3 [Hi-Z] switch (channel 4)
This switch is used when connecting a device directly to the
mixer without a DI (direct injection box) for example,
instruments with passive pickups, such as an acoustic-electric
guitar or electric bass without battery. This function is effective
only for the phone jack input.
4 [LINE] input jacks (channels 5/6, 7/8, 9/10)
Connect line-level devices such as electronic instruments,
acoustic-electric guitars, CD players, and portable audio
players. These jacks support phone, RCA-pin, and stereo-mini
plugs.
RCA-pin Stereo-mini
NOTE For the channel 7/8 input, if both phone and RCA-pin jacks are
used at the same time, the phone jack will take priority. For the
channel 9/10 input, if both phone and stereo-mini jacks are
used at the same time, the stereo-mini jack will take priority.
The signal from the device connected to another jack will be
muted.
5 [MONITOR OUT] jacks
These are for connection to a powered speaker for monitoring
purposes, and output a mix of the signals from channels 1 to
9/10. You can adjust the output level using the [MONITOR OUT]
control !. If only the [L (MONO)] jack is used, the signals from
the L and R channels are mixed and output.
6|[SUBWOOFER OUT] jack
This is for connection to a powered subwoofer, and outputs a
mono signal. If this jack is in use, the low frequencies below
120 Hz to the [SPEAKERS L/R] jacks will be cut. The output
level is linked to that of the [MASTER LEVEL] control (C).
7 [REVERB FOOT SW] jack
This is for connection to an unlatched-type footswitch such as
the Yamaha FC5 useful for solo performers, since you can
toggle the reverb on and off as needed with your foot.
8 [SPEAKERS L/R] jacks
Use commercially available speaker cables to connect the
speakers. These jacks support TS phone plugs.
9 [IMPEDANCE SELECT] switch
Set this switch to match the impedance of the connected
speakers. If you are unsure of the impedance of the connected
speakers, set this switch to “4Ω”. Changing this setting changes
the maximum output from the amp and changes the conditions
for which the [LIMITER] LED comes on.
NOTICE
• Make sure the power switch is off before changing the setting of this
switch.
• Setting this switch incorrectly could result in damage to the mixer/your
speakers.
) [PHANTOM (CH1/2)] switch/LED
When this switch is on, the LED lights indicating that phantom
power is available for channels 1 and 2. Turn this switch on to
supply power to condenser microphones or a DI (direct
injection box).
NOTICE
Follow the important precautions below, in order to prevent noise and
possible damage to external devices and the mixer when you operate
this switch.
• Be sure to leave this switch off if you do not need phantom power, or
when you connect a device that does not support phantom power to
channels 1 and 2.
• Do not connect/disconnect a cable to/from channel 1 or 2 while this
switch is on.
• Turn the [LEVEL] control of channels 1 and 2 to the minimum before
operating this switch.
! [MONITOR OUT] control
Determines the signal level output from the [MONITOR OUT]
jacks (5). The [MASTER LEVEL] control does not affect the
[MONITOR OUT] signal.
@ Equalizer controls [HIGH, MID, LOW]
The equalizer shapes the [HIGH], [MID], and [LOW] audio
frequencies. Turning the control to the right amplies (boosts)
the corresponding frequency band, while turning it to the left
attenuates (cuts) the band. Setting the control to the D
position produces a at response in the corresponding band.
# [REVERB] button/LED
When this button is on, the LED lights indicating that you can
apply reverb. This button is off when you turn on the mixer.
(Unlike other switches, this button cannot be locked.)
$ REVERB [TYPE/TIME] control
Determines the reverb type and its length. Turning the control to
the right lengthens the time of the selected reverb type.
“HALL”: Simulated reverb of a large space, such as a
concert hall.
“PLATE”: Simulated metal plate reverb, producing a more
hard-edged and bright sound.
“ROOM”: Simulated acoustic ambience of a small room.
“ECHO”: Echo effect suitable for vocals.
% [REVERB] controls (channels 1– 4)
Determines the amount of reverb for each channel when the
[REVERB] button (#) is on.
^ [N STEREO /O MONO] switches
(channels 5/6, 7/8, 9/10)
Setting the switch to
N
STEREO” will assign the signals from
the L and R channels to each left and right speaker and output
each signal. Setting the switch to “
O
MONO” will mix the output
of different L and R sources to output the same signal to both
the left and right speakers. For keyboards with mono output,
guitars, or other non-stereo sound sources, when the switch is
set to “
O
MONO”, the stereo jacks can be conveniently used as
multiple mono jacks.
& Level meter
The level meter shows the level of output signal from the
[SPEAKERS L/R] jacks.
NOTICE
If used at a high volume so that the [LIMITER] LED flashes continuously,
the internal power amplifier section is being excessively overloaded and
may malfunction. Reduce the output level with the [MASTER LEVEL]
control so that the indicator flashes only briefly on the highest transient
peaks.
* [POWER] LED
This LED lights when the power is turned on by pressing the
power switch.
( [FEEDBACK SUPPRESSOR] switch/LED
When this switch is on, the LED lights indicating that feedback
is automatically suppressed. (This utilizes a seven-band notch
lter. When this switch or the power switch is off, the notch lter
will be reset.)
A [LEVEL] controls
Use these controls to adjust the volume for each channel. To
reduce noise, set any [LEVEL] controls on unused channels to
the minimum.
B [MASTER EQ] control
Use this control to adjust the overall sound frequency balance.
The center position “MUSIC” is a basic setting and if you turn
the control to the left, this creates an optimum setting for
speech, cutting unneeded low range frequencies. Turning the
control to the right creates an optimum setting for playback of
sound sources, by boosting the low and high ranges. If you turn
the control further to the right, the [BASS BOOST] LED lights
indicating that the bass boost function is active, giving you an
even more powerful bass tone.
C [MASTER LEVEL] control
Determines the volume of the signal output from the
[SPEAKERS L/R] and [SUBWOOFER OUT] jacks. This allows
you to adjust the overall volume without changing the relative
volume balance among the various channels.
D Vents
There are vents located on both sides of the mixer, and a
cooling fan is installed on the exhaust side. Do not block the
vents on either side when using the mixer.
E [AC IN] jack
Connect the included power cord here.
F [ ] (Power) switch
For turning the power of the mixer on (O) and off (N).
NOTICE

Precautions for Rack Mounting
This mixer is rated for operation at ambient temperatures ranging from 0 to 40 degrees
Celsius. If you install this mixer along with other devices in a poorly ventilated EIA
standards rack, the ambient temperature inside the rack may rise, resulting in
inefficient performance. Be sure to rack-mount in the following conditions so the mixer
does not overheat.
• When mounting the mixer in a rack with devices such as power ampliers that generate a
signicant amount of heat, leave more than 1U of space between it and other equipment. Also,
either leave the open spaces uncovered or install appropriate ventilating panels to minimize the
possibility of heat buildup.
• To ensure sufficient airow, leave the rear of the rack open. If you’ve installed a fan kit in the rack,
there may be cases in which closing the rear of the rack will produce a greater cooling effect.
Refer to the rack and/or fan kit manual for details.
Troubleshooting
Check the following items before contacting a Yamaha dealer.
If the symptoms are not improved, contact your nearest Yamaha dealer.
Power does not come on.
Did you rmly and securely connect
the power cord?
Power shuts down suddenly.
Are the vents of the mixer blocked?
Since inadequate ventilation can result in
overheating the mixer, the power may be
turned off automatically to prevent
overheating. Ensure proper ventilation for
cooling, and then turn on the power again.
No sound is heard.
Did you connect the mixer’s
[SPEAKERS L/R] jacks and the
speakers’ input jacks using the proper
speaker cables?
Did you rmly and securely connect
the speaker cables?
