3. Description

a. Mono Input

1. MIC Input

Each mono input channel offers a balanced microphone input via the XLR connector

and also features a switchable +48V phantom power supply for condenser

microphones. The XLR jack is configured for pin 1 (ground), pin 2 (positive (+)) and

pin 3 (negative (-)).

2. LINE Input

The LINE input is designed to accept balanced or unbalanced line level signals such

as those from keyboards, drum machines or samplers. There is enough gain

available on the line input to accept even lower level signals such as those from an

unbalanced microphone or guitar output. If a balanced signal is to be connected to

the line input, then a ¼” TRS (stereo) phone plug should be wired for the tip (positive

(+)), the ring (negative (-)) and the sleeve (ground).

Be very careful during the installation: touching live wires can cause life-threatening electroshocks.

Keep this device away from rain and moisture.

Unplug the mains lead before opening the housing.

PROMIX1212E_v2 HQPOWER

NOTE: Either the MIC or the LINE input of a given channel can be connected at one time. Never connect both

simultaneously to the same channel.

3. INSERT

These mono channels are equipped with insert jacks to connect external signal processors such as

compressors, noise suppressors or effect devices, to the individual input channels. Insert points are useful

for adding dynamic processing or equalization to a channel or the mix. Unlike reverberation, which is

usually added to the dry signal, dynamic processing is normally applied to the entire signal. These jacks

can also be used as a direct output by sending the signal from the ring. To do so, insert a ¼” plug halfway

into the jack so the tip of the plug connects to the ring of the jack.

4. TRIM

The TRIM control adjusts the input sensitivity (channel gain) of the MIC and LINE inputs on the mono input

channels. This control can be adjusted to accommodate input signals from a wide variety of sources, from

the high outputs from keyboards or drum machines to the small signal outputs of microphones. This wide

range eliminates the need for MIC / LINE switching. The best S/N balance and dynamic range will be

achieved if you adjust the TRIM control on each channel separately so that the PEAK LED (11) for that

channel lights occasionally.

NOTE: This control should always be turned fully anticlockwise whenever you connect or disconnect a signal

source to one of the inputs.

5. EQUALIZER

All mono input channels are fitted with three-band EQ. The upper (HIGH) and lower

(LOW) shelving controls have their frequencies fixed at 12kHz and 80Hz respectively.

The midrange control has a peaking response, with Q fixed at 2 octaves and the

frequency at 2.5kHz. All three bands have up to 15dB of cut and boost with a centre

detent for “off”.

6. AUX SEND 1, 2

Both AUX SEND 1 and 2 are mono and post EQ, and control the level of the signals

sent to the AUX buses.

• AUX SEND 1 is pre-fader and the signal sent to the AUX 1 bus will be unaffected

by the channel fader setting.

• AUX SEND 2 is post-fader and the signal sent to the AUX 1 bus will be affected

by the channel fader setting.

For almost all effects send purposes you may want to use the post-fader AUX 2 so that when a fader level

is adjusted, any reverb sent from that channel follows the fader. Otherwise, when the fader is pulled down,

the reverb of that channel would still be audible. You can also use the AUX SEND 2 to feed inputs to a

multi-track recorder or any unbalanced line level application. On the other hand, for cueing purposes and

monitor amplifiers, use the pre-fader AUX 1.

8. FX Control

This control alters the signal level sent to the FX send outputs and the built-in digital

effects processor. The FX send signal can be used in conjunction with external signal

processors (this signal of which can be returned to the mixer via the AUX return

input), or simply as an additional auxiliary output.

9. MON Control

The MON control is designed for feeding a separate monitor mix to the musicians

onstage via the MON output jack.

10. PAN Control

The channel PAN positions the output of the channel in the stereo field of the main mix if the L-R selection

switch (13) is depressed). Its constant power design ensures there are no level discrepancies whether the

signal is hard-panned, centre-staged or somewhere in between. The channel PAN also determines the

stereo position of any signal routed to the G1-2 bus when the G1-2 bus is selected with the G1-2 switch

(14).

PROMIX1212E_v2 HQPOWER

11. PEAK LED

The PEAK LED illuminates when a channel is going into overload.

It detects the peak level after the EQ and will light at 3dB before

clipping to warn that the signal is approaching overload. You do

not want the PEAK LED to light except very intermittently during a

take or a mix. If it does light persistently, reduce input gain with

the TRIM control (4).

12. PFL Selection Switch

The PFL (Pre-Fader Listen) switch enables monitoring the mono

signal of any channel(s) selected (button depressed) at nominal

levels through the headphones or control room monitor outputs.

The signal is post EQ and independent of the channel fader’s

position.

13. L-R Selection Switch

When the L-R switch is depressed, the post-fader channel signal

is fed to the master L-R faders.

14. G1-2 Selection Switch

This switch enables to select the channel for routing to the G1-2

stereo bus, controlled by the master G1-2 fader. This signal is

post-fader and the stereo placement is adjusted by the PAN control. The G1-2 bus

offers you a second stereo submix with its own stereo G1-2 submaster fader. It can

be used as a convenient mixing aid both live and in the studio.

15. Channel FADER

This fader allows users to adjust the signal level from the corresponding input

channel that is to be sent to the destinations selected by the 1-2 and L-R buttons.

b. Stereo Input

4. TRIM

The stereo TRIM control operates in the same manner as the mono TRIM control.

The stereo inputs are designed for any line level signal. Most line level sources such

as MIDI instruments and effects units will have their own output level control.

However, any added adjustment necessary for proper levelling can be done with the

TRIM control.

5. EQUALIZER

The stereo EQUALIZER operates in the same manner as the mono EQUALIZER.

The left and right signals will be affected equally. Using one stereo equalizer is

generally preferable to using two mono equalizers when equalizing a stereo signal as

it avoids possible discrepancies between the left and the right settings.

6. AUX SEND 1, 2

Same function as for the mono channel.

8. FX Control

Same function as for the mono channel.

9. MON Control

Same function as for the mono channel.

11. PEAK LED

Same function as for the mono channel.

12. PFL Switch

Same function as for the mono channel.

13. L-R Selection Switch

Same function as for the mono channel.

14. G1-2 Selection Switch

Same function as for the mono channel.

15. Channel FADER

Same function as for the mono channel.

PROMIX1212E_v2 HQPOWER

16. L (MONO) LINE Input

On the stereo input channels, the ¼” line inputs are designed for stereo or mono line level signals such as

those from a keyboard, drum machine, CD player or sampler. However, these inputs can also be used as

standard mono line inputs by connecting the signal to the L (MONO) line in. This signal will be routed

equally to the BAL control and the left and right outputs in the same way as the standard line input

channels. For the stereo line inputs the mono channel PAN control (10) is replaced by the BALANCE

control (18).

17. R LINE Input

When using stereo input channels as stereo input channels, the left signal should be connected to the L

input and the right signal to the R input. These signals will be routed to the AUX, EQ and channel FADER

controls equally, and will retain their stereo separation. The AUX, EQ, BAL and channel FADER controls all

operate similarly to those on the mono input channels. When a stereo signal is put into a stereo input

channel, these controls will affect the left and right signals equally. The stereo line input jacks are ¼” TRS

balanced phone jacks (tip = +, ring = -, sleeve = ground).

18. BAL Control

For a mono input to the L (MONO) input the function of the control is the same as the PAN controls (10) of

the mono channels. However, when a channel is run in stereo, this control functions as a BALANCE

control, determining the relative balance of the left and right channel signals being sent to the left and right

MASTER MIX buses. For example, with the BALANCE control turned fully clockwise, only the right portion

of the channel’s stereo signal will be routed to the MASTER MIX. The BALANCE also determines the

relative amount of left and right channel signals being sent to buses G1 and G2 respectively when the G1-2

selection switch is depressed.

c. Master Section

19. STEREO AUX RETURNS (left/mono, right)

The AUX RETURN jacks are the mono or stereo returns for AUX 1 and 2. If you connect a signal to the

left/mono return jack only, the AUX RETURN will operate in mono and the signal will be routed to the

respective AUX RETURN controls (37) and then mixed into the left and right MAIN MIX STEREO outputs

(27) and/or G1-G2 outputs (24), depending on whether you selected either or both outputs with the L-R

(40) or AUX RETURN G1-2 (41) switches.

20. AUX SENDS

AUX SEND 1 and 2 are the outputs for the signals sent from the AUX SEND controls (6). They are ¼”

unbalanced phone jacks (tip = +, sleeve = ground). AUX 1 is pre-fader and AUX 2 is post-fader.

22. FX SEND

These ¼” TS outputs are the final output from the EFX send mixing bus. This feed may be used to connect

an external digital effects processor or even to an amplifier and speakers depending on your desired

settings. They are ¼” unbalanced phone jacks wired: tip = +, sleeve = ground.

23. MON SEND

This monitor jack is the output for the signals sent from the channel MON control (9). This is a ¼”

unbalanced phone jack wired: tip = +, sleeve = ground.

PROMIX1212E_v2 HQPOWER

24. G1-2 OUT

A channel’s output will be routed to the G1-2 GROUP OUTS (24) by depressing the G1-2 selection switch

(14). These outputs are ¼” TRS balanced phone jacks wired: tip = +, ring = -, sleeve = ground.

25. CTRL R OUT

The L-R control room outputs can be connected to an amplifier to power stereo control room (or other)

monitor speakers and are ¼” unbalanced phone jacks wired: tip = +, sleeve = ground.

26. MONO OUT

This jack outputs a monaural mix of the stereo signal from the ST bus. The level for this output is controlled

by the MONO fader in the master control block. The output is a mix of the ST bus’s L and R signals. This is

best suited for use with a mono sound system or for the addition of a subwoofer to your set of speakers,

adding much more punch to low frequencies. This is a ¼” unbalanced phone jack wired: tip = +, sleeve =

ground.

27. STEREO OUT

The stereo outputs consist of both left (L) and right (R) balanced XLRs, wired: pin 1 = ground, pin 2 = hot +,

pin 3 = cold -, and ¼” unbalanced phone jacks wired: tip = +, sleeve = ground.

28. TAPE IN

These jacks will accept the signal from an external device with a stereo output such as a cassette recorder.

29. REC OUT

The REC outputs also provide an output of the MASTER MIX. These outputs are RCA jacks and designed

primarily for inputs to tape recorders, etc.

30. PHONES OUT

The PHONES output will feed headphones and is a ¼” TRS jack, wired as tip = left signal, ring = right

signal, sleeve = ground.

31. MAIN POWER Switch

43. PHONES/CTRL ROOM

The level of the selected signals is adjusted with this control and routed to both the CTRL R OUT (25) and

PHONES OUT (30).

44. MONITOR Selection Switches (PFL, L-R, G1-2)

This mixer allows you to monitor singly the L-R main mix, the G1-2 group mix or the pre-fader PFL signal

by selecting one of the appropriate switches.

45. PHANTOM POWER ON/OFF Switch

When using condenser microphones, +48VDC can

be switched on or off to the XLR microphone inputs

for all mono channels. When the switch is in the ON

position, +48VDC will be provided between pins 2

and 3 of all mono microphones XLR input

connectors.

It is safe to connect balanced dynamic microphones

or line level devices even if this switch is on.

Connecting unbalanced devices or devices whose

transformers are centre-grounded will cause hum or

malfunction. Shorting the +48VDC can also damage

your mixer. Mute the monitors or PA speakers when

turning the phantom power on or off.

46. PHANTOM POWER LED

This red LED lights when the phantom power is turned on.

47. AUX SEND 1-2

These controls will alter the signal level being sent to the auxiliary mixing buses 1 and 2, the signal of which

is suitable for connecting stage monitors allowing you to listen to the music being played.

3. Description

a. Mono Input

1. Entrée MIC

Chaque canal d’entrée mono offre une entrée symétrique pour microphone à partir

d’une connexion XLR et dispose d’une alimentation fantôme de +48V pour des

microphones à condensateur. La connexion XLR est configurée comme suit : broche

1 (masse), broche 2 (positif (+)) et broche 3 (négatif (-)).

2. Entrée en ligne LINE

L’entrée LINE a été conçue pour accepter des signaux à niveau en ligne symétriques

ou asymétriques comme ceux d’un clavier, d’un module de batterie électronique ou

d’échantillonneurs. Il y a suffisamment de gain pour y brancher de faibles signaux

comme ceux d’un microphone asymétrique ou d’une guitare. Si vous désirez

connecter un signal symétrique à l’entrée LINE, câblez une fiche TRS de ¼” comme

suit : la pointe (positif (+)), la bague (négatif (-)) et le manche (masse).

Être lors de l'installation : toucher un câble sous tension peut causer des électrochocs mortels.

Protéger l’appareil contre la pluie et l’humidité.

Débrancher le câble d'alimentation avant d’ouvrir le boîtier.

PROMIX1212E_v2 HQPOWER

REMARQUE : Ne connecter que l’entrée MIC ou l’entrée LINE d’un canal. Ne jamais connecter les deux aux

deux canaux simultanément.

3. INSERT

Ces canaux mono sont équipés de jacks d’entrée pour la connexion de processeurs de signaux externes

comme p.ex. des compresseurs, des réducteurs de souffle ou autres, aux canaux d’entrée individuels. Les

jacks INSERT sont pratiques pour le traitement dynamique ou l’égalisation d’un canal. Le traitement

dynamique, contrairement à la réverbération qui est généralement ajoutée au signal direct, s’applique sur

le signal en entier. Ces jacks peuvent également être utilisés comme sortie directe. Pour ce faire, insérer

une fiche ¼” à moitié dans le jack pour que la pointe de la fiche se connecte à la bague du jack.

4. TRIM

Le réglage TRIM ajuste la sensibilité à l’entrée (le gain du canal) des entrées MIC et LINE sur les canaux

d’entrée mono. Il est possible de régler de telle façon à accepter des signaux d’entrée de sources diverses,

du signal fort d’un clavier ou d’un module de batterie électronique au signal faible d’un microphone. Cette

étendue élimine la commutation MIC / LINE. Vous obtiendrez le meilleur rapport S/B et étendue dynamique

en réglant le TRIM de chaque canal séparément de manière à ce que la LED DE SURCHARGE

(« PEAK ») (11) du canal ne s’illumine que occasionnellement.

REMARQUE : Positionnez ce réglage complètement à gauche lors de la (dé)connexion d’une source de signal.

5. ÉGALISATION

Tous les canaux d’entrée mono sont munis d’une égalisation 3 bandes. Les

potentiomètres des aigus (HIGH) et des graves (LOW) ont une fréquence de 12kHz

et de 80Hz respectivement. Le potentiomètre des moyens a une réponse en crête,

avec un Q fixé à 2 octaves et une fréquence de 2.5kHz. Les trois bandes ont une

intensité d’augmentation et de diminution jusqu’à 15dB avec un déclic central pour

« off ».

6. AUX SEND 1, 2

Les deux AUX SEND 1 et 2 sont mono et post-EQ, et sont utilisés pour régler le

niveau du signal vers les AUX.

• AUX SEND 1 est pré-atténuation et le signal vers AUX 1 ne sera pas influencé par

un réglage de la glissière.

• AUX SEND 2 est post-atténuation et le signal vers AUX 1 sera influencé par un

réglage de la glissière.

Utilisez le réglage AUX 2 (post-atténuation) pour tous les effets pour que la

réverbération réponde aux réglages de la glissière et que la réverbération soit coupée lorsque vous

positionner la glissière sur la valeur minimale. Utilisez l’AUX SEND 2 pour alimenter les entrées d’un

enregistreur multipiste ou toute application en ligne. Pour des applications de repérage ou de balance,

utilisez l’AUX 1 pré-atténuation.

8. Réglage FX

Ce bouton permet de régler le signal vers les sorties FX et le processeur à effets

numérique interne. Ce signal peut s’utiliser avec des processeurs d’effets externes

(ce signal peut ensuite être renvoyé à la table de mixage via l’entrée retour AUX), ou

comme sortie auxiliaire additionnelle.

9. Réglage MON

Permet l’alimentation d’une enceinte de retour sur scène via le jack de sortie MON.

10. Réglage PAN

Le PAN positionne le signal de sortie du canal dans le champ stéréo du mixage général. Ses spécifications

éliminent les décalages de niveau de volume, qu’il soit situé sur un côté, au centre ou entre-deux. Le canal

PAN détermine également la position stéréo d’un signal envoyé vers G1-2 lorsque G1-2 est sélectionné

(14).

PROMIX1212E_v2 HQPOWER

11. LED de SURCHARGE

La LED de SURCHARGE (PEAK) s’illumine dès que le canal

atteint la surcharge. Il détecte le niveau de crête après l’EQ et la

LED s’illumine à partir de 3dB avant la saturation pour avertir que

le signal approche la surcharge. Veillez à ce que la LED ne

s’illumine pas excepté de manière intermittente pendant une prise

ou le mixage. Si la LED s’illumine régulièrement, diminuez le gain

d’entrée avec le potentiomètre TRIM (4).

12. Interrupteur de sélection PFL

Cet interrupteur PFL (Pre-Fader Listen) permet d’écouter un

signal mono sélectionné (bouton enfoncé) à l’aide d’écouteurs ou

depuis des sorties de monitorage. Le signal est post-égalisation

et indépendant de l’atténuateur de la voie.

13. Interrupteur de sélection L-R

Le signal post-atténuation est envoyé vers les glissières maîtres

L-R lorsque l’interrupteur est enfoncé.

14. Interrupteur de sélection G1-2

Cet interrupteur permet de sélectionner le canal qui sera envoyé

et contrôlé par la glissière maître G1-2. Le signal est post-

atténuateur et l’emplacement stéréo se règle à l’aide du régulateur PAN. Les jacks

G1-2 offrent un second mixage stéréo avec glissière stéréo G1-2.

15. GLISSIÈRE

Cette glissière règle le niveau du signal envoyé vers 1-2 ou L-R.

4. TRIM

Le régulateur TRIM du canal stéréo fonctionne de la même manière que celui du

canal mono.

5. ÉGALISEUR

L’égaliseur du canal stéréo fonctionne identiquement à celui du canal mono. Les

signaux de gauche et de droite seront influencés de manière équivalente. Il est

préférable d’utiliser un égaliseur stéréo à deux égaliseurs mono avec un signal stéréo

afin d’éviter des différences de réglage entre les égaliseurs.
