Back Panel Layouts
UPA‐1 Back Panel
1.Status Led Selector ‐ Status LEDs can be turned on and off with this selector.
2.RCA /Unbalanced Audio Input ‐ Standard RCA input connection that connects to a standard RCA audio output connection on a preamplifier, receiver or multi‐channel processor.
3.Unbalanced/Balanced Input Selector – When turned towards ‘Un‐Bal’, the RCA (unbalanced) input is chosen and active. When turned towards ‘Bal’, the XLR/Balanced input is chosen and active.
4.XLR /Balanced Audio Input ‐ Standard XLR input connection that connects to a standard XLR audio output connection on a preamplifier, receiver or multi‐channel processor.
5 ‐ 6: Speaker Terminals ‐ These 5 way binding posts accept stripped speaker wire, banana plugs, or spade connectors. Be sure to observe correct polarity when connecting speakers and be sure that the wires do not touch between positive and negative terminals.
When using the UPA‐1 to ‘bi‐wire’ a speaker, use both negative and both positive terminals to connect to the corresponding negative and positive terminals on your speakers. In a standard wiring situation, use only one negative terminal and one positive terminal to single negative and positive terminals on the speaker.
Note: Potentially lethal voltages present! Never connect, disconnect or modify speaker wiring with the amplifier turned on.
7.Voltage Indicator – All Emoitva amplifiers operate on either 115V or 230V. The voltage is detected when the amplifier is turned on, and is identified by the indicator lights. There are no user adjustments, the amplifier automatically adjusts to the voltage.
8.Remote Trigger Input/Output – The UPA‐1 can be remotely triggered by another device, and in turn, remotely trigger another device. When a remote trigger output from a preamplifier, processor or other audio device is connected to the trigger input here, the amplifier will power up and shut down along with the first device. Another device (CD player, amplifier, etc) can be added to this chain using the trigger output.
A 3.5mm, 5‐12 volt mono audio cable is used for both inputs and outputs. If building your own cable, center is positive and outer shield is negative.
9.Master Power Switch ‐ This rocker switch provides the master power for the amplifier. After it is in the ON position, the amplifier can be turned on manually from the front panel switch or automatically with the trigger input via 3.5mm input jack.
Under normal use, this switch should remain on, leaving the amplifier in standby position, and coming to full power with either the front panel ‘STANDBY’ button, or activation through the remote trigger.
