Connections

Connecting the INPUT

The Input has a balanced screw terminal connector that accepts a line-level signal. The screw terminals should be connected as shown in the following figure:

Connecting the UNBALANCED IN

The UNBALANCED IN uses an RCA-type connector. It accepts a line-level signal (–10 dBV) with the SENSITIVITY switch in the 0 dB position (pushed IN). When connecting a low-level signal, push the SENSITIVITY switch OUT (20 dB position). Use high-quality, two-conductor shielded cable to make these connections.

Strip the wire back about 1/2" inch, loosen the screw enough to loop the wire around the shaft of the screw (clockwise), and tighten down the screw with either a slot-head or phillips-head screwdriver.

Use high-quality, three-conductor shielded cable for balanced connections. The better the shield, the better the audio signal is protected from induced EMI and RFI.

If connecting an unbalanced line-level signal to the Input, wire the connections as shown in the following figure:

Connecting the Speakers

The speaker output connectors are screw terminals. Use 16 or 18 gauge wire for connecting the amplifier outputs to the speakers. Strip the wire back about 1/2" inch, loosen the screw enough to loop the wire around the shaft of the screw (clockwise), and tighten down the screw with a slot- head screwdriver.

If using a 4-ohm speaker, connect the 4Ω output terminal to the "+" terminal on the speaker, and connect the "0" output terminal to the "–" terminal on the speaker.

If using a constant-voltage distributed speaker system, connect either the 25V, 50V, 70V, or 100V output terminal to the "+" side of the speaker system, and connect the "0" output terminal to the "–" side of the speaker system. Make sure that the taps on the speakers add up to no more than the rated power for the UP4000 Series Amplifier being used.

CAUTION: To prevent the risk of electric shock, never touch the bare wires coming

from the OUTPUT TERMINALS of the amplifier when it is switched on.

When the connections have been made, insulate the 50V, 70V, and 100V terminals of the amplifier using the protective cover supplied.

Connecting the POWER INPUT 24V.D.C.

Connect a 24 VDC power supply to these spring terminals as an alternate method to power the UP4000 Series. To minimize the voltage drop across the wire and prevent overheating, use at least 16 AWG wire for the UP4061, and 14 AWG wire for the UP4121 and UP4161.
