INPUTS - The UA series allows you to use two types each of input connectors to the UA-3000, UA-4000 and UA-5000 respectively.
XLR INPUT TERMINAL (Figure 5)
A XLR female jack is used to connect the output signal from a mixer, cross-over or EQ to Your UA series amplifiers. A balanced connection is
recommended for cable runs longer than 20ft. When constructing your own XLR cables follow the pin configuration described below for proper
connections.
RCA CONNECTOR (Figure 6) – For UA-3000 only
This is the input terminal of the audio signal, RCA connector is unbalanced specification. For cable runs shorter than 20ft., you may choose the
RCA unbalanced input option. This unbalanced input option may be more convenient for most users due to the abundant supply of prefabricated
cables available at your local audio dealer. Please refer to the following figure-6 for the specifications of the pinout.
EURO BLOCK DIAGRAM (Figure 7) – For UA-4000 & UA-5000 only
Internally connected parallel to the XLR connector.
OUTPUTS -
BINDING POST/BANANA PLUG: Connect your speakers to the binding post outputs on the rear of the amplifier. The speaker wire may be connected
by bare wire (directly connected, usually for permanent connections), banana plug, orspade connector. Connections are made to channel one and
channel two outputs for Stereo Mode or across the red terminals of channel one and channel two for Mono Bridge Mode (UA-4000 & UA-5000 only).
IMPORTANT NOTICE: Although a speaker will operate with the positive and negative leads plugged into either terminal on the amplifier binding post,
be sure to plug the negative lead into the black terminal and positive lead into the red terminal. Ensuring proper polarity will avoid speakers being out
of phase that can cause a loss of bass response.

When connecting your speakers to the amplifier using banana plug, be sure that the red and black caps on
the binding post are completely screwed in. Insert the banana plug into the caps of the binding post, be sure
that the banana plug is inserted securely to avoid the risk of popping out.
BARE WIRE CONNECTION: (Figure 9)
When connecting your speakers to the amplifier using bare wire, unscrew the red and black caps on the
bindingpost, be sure not to completely remove or unscrew the red and black caps. Strip back the wire
insulation ½” (13mm). Insert the bare wire into the hole that was revealed by unscrewing the binding post
cap. After inserting the wire into the binding post hole, screw the binding post cap down on the wire. To
reduce the risk of shock or damage to your amplifier, be sure that the wire connected to one binding post
does not come in contact with that of another.
SPADE CONNECTOR: (Figure 10)
When connecting your speakers to the amplifier using spade connector, unscrew the red and black caps on
thebinding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade
connector intothe binding post and tighten the caps down on the spade connector. To reduce the risk of shock
or damage to your amplifier, be sure that the wire connected to one binding post does not come in contact
with that of another.

OPERATING MODES
STEREO OPERATION : Connect your inputs into channel one and channel two (also channels three and four for the UA-4000 & UA-5000) of the amplifier.
Connect your speakers to the outputs on the rear of the amplifier. Be sure that your front gain controls are turned down to their lowest level (fully
counterclockwise). Turn your amplifier on. Turn your input source level up. Use your front gain controls to regulate the output volume. Be sure not to raise the
volume to the clip level, however an intermittent clip signal is acceptable.
MONO BRIDGE OPERATION (UA-4000 & UA-5000 only): Be sure your amplifier and all other audio equipment are powered down. Press the
Bridge button. Connect input signals to channel one and three. Connect your speaker across the red output binding post on the rear of your amplifier. Turn your
equipment on (your amplifier should always be the last item you turn on). Apply an input source signal to your amplifier. Use the channel one and three gain to
regulate your amplifier output.
PARALLEL MONO (UA-4000 & UA-5000 only): Parallel ties the two channel line inputs together, so that they will both be driven by the same signal,
without the need for external jumpers or wiring. Four amplifier channels will operate independently. Though they carry the same signal, their gain controls affect
only their respective channels, and they both must use their respected speaker outputs. Never attempt to parallel the speaker outputs, this may cause serious
damage to your amplifier! To run in parallel mono mode connect your system as you would if you were going to run in stereo mode. Then press the Parallel
button. Be sure the amplifier is off or the power is disconnected before making any changes.
SUBWOOFER MODE: This mode sends low frequencies to your speakers without the use of an external cross-over. The subwoofer operation can be
operated in mono only. Set the subwoofer mode switch to the “ON” position. Use the frequency selector to adjust the subwoofer output frequency from 20Hz to
200Hz.

PROTECTION
1. Switch ON Mute Protection
The mute circuit is used at the inputs when the unit switched ON, output of between a few seconds the amplifier will be muted. This is done so that turn-on/ off
noises from mixers and other gear is blocked in case the entire system is powered up at once.

2. Short Circuit Protection
The UA series comes with built-in Output Short Circuit Protects. The Output Short Circuit Protection protects the output
devices of the amplifier from short circuits and stressful loads. If your speaker lines shorted, the amplifier automatically
detects this problem and discontinued operation for that channel. If one side of your amplifier becomes shorted and goes
into protect mode, the other side will continue to operate normally. Channel output during the “Short Circuit Protection" will
be interrupted (i.e. no sound output). Short Circuit Protection can usually be traced back to the signal output line (i.e.
speaker line). Check the line from the output terminal of the amplifier to the speaker. If this line is good, check the internal
speaker connections and components. A short circuit will usually be traced to a bad cable or a bad speaker component
and is rarely traced to the amplifier itself.
3. Overheating Protection
The UA series amplifiers are cooled by Dual 2-speed fans, and always are kept at moderate temperature. During low level output the fans run at normal
speeds. During high output and as heat raises, (exceeding 50°C.), the fans will run at higher speeds to aid the cooling process. If the heatsink temperature
exceeds 91°C., the amplifier will mute until the amplifier cools down. When the amplifier cools below 90°C., the amplifier will return to normal operations. Be
sure not to operate your amplifier below the minimum load ratings to reduce the risk of overheating problems.
4. DC Circuit Protection
If dangerous subsonic frequencies or direct current (DC) is detected in the amplifier's output, the unit will activate its DC/low-frequency
protection circuitry and the amplifier will be muted.This protects the loads and prevents oscillations. The unit will resume normal operation while
the amplifier no longer detects dangerous low-frequency or DC output.
