INPUTS -
The UA series allows you to use two types each of input connectors to the UA3000 and UA-4000 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.

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 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.
