BACK PANEL FEATURES

PAGE INPUT (15)

The Page input is a 600 ohm transformer balanced input. The telephone page input should be connected to the + and terminals; if a shielded cable is used, the shield should be connected to the terminal and not connected at the source.

PAGE GAIN TRIM (16)

Controls the signal level of the Page input.

PAGE MUTE THRESHOLD (17)

Adjusts the level of incoming signal from Page input required to activate the muting of Channels 1 to 4. Clockwise rotation decreases the amount of signal required for muting. Full counterclockwise rotation will disable muting.

NOTE: Signal at Page input with appropriate Mute Threshold setting will mute Channels 1 to 4.

EXTERNAL REMOTE VOLUME (18)

These terminals allow connection of an external volume control. To gain complete control of volume from the external volume control, the front panel Master volume control must be set to maximum. The external volume control should be connected as shown in Figure 1.

CHANNEL 1 MUTE THRESHOLD (19)

Adjusts the level of incoming signal from Channel 1 required to activate the muting of Channels 2 to 4. Clockwise rotation decreases the amount of signal required for muting. Full counterclockwise rotation will disable muting.

NOTE: Signal at Channel 1 input with appropriate Mute Threshold setting will mute Channels 2 to 4.

CHANNELS 1 TO 4 SCREW TERMINAL INPUTS (20)

Channels 1 to 4 have low impedance mic and high impedance line level input capability. The low impedance mic input

( , Low Z +, Low Z -) is an electronically balanced input with built-in 24 V DC phantom power. The high impedance line level input is a single-ended input. To use the High Z screw terminals, a jumper MUST be placed from High Z (-) to .

CHANNEL 1 AND CHANNEL 2 XLR CONNECTORS (21)

These inputs are in parallel with the Low Z screw terminal inputs. Pin 2 on the XLR corresponds to the Low Z (+) screw terminal. Phantom power is supplied.

CHANNEL 3 AND CHANNEL 4 RCA INPUT JACKS (22)

These inputs are resistively summed to mono and are in parallel with the High Z screw terminal inputs. The shorting jumpers on the screw terminal inputs are shipped in place for these inputs.

MUTING SCREW TERMINALS (23)

Provides connection for external switch closure to activate muting functions. A switch closure from terminal 1 to mutes Channels 1 to 4. A switch closure from terminal 2 to mutes Channels 2 to 4.

24 V DC OUTPUT TERMINALS (24)

Provides connection for a low current (20 mA) 24 V DC output for powering low current external add-on equipment.

5

CH 4 OUT RCA JACK (25)

Provides a direct output of Channel 4 that is independent of EQ and muting. This output is ideal for music on hold applications.

AUX OUT RCA JACK (26)

Provides a line level output to drive external power amps, hearing assistance systems, or as a record output for taping.

This output is after the EQ and Master Volume Control.

LOOP IN/LOOP OUT JACKS (27)

Functions as a preamp out/power amp in patch point. The Loop Out signal is a post EQ/Master Volume line level output.

LINK SWITCH (28)

Breaks the connection between the preamp and the power amp (Loop Out/Loop In). These two jacks are shorted together when the switch is in the "In" position. To use the Loop Out/In jacks as a patch point, the switch must be placed in the "Out" position. The line level output signal is present at the Loop Out jack regardless of switch setting.

OUTPUTS (29)

A direct output, as well as several isolated transformer outputs, are provided to allow the proper interface between the amplifier and the speaker system. The direct output allows direct connection to a 4 ohm speaker system. To use this output, disconnect the jumper between the 4 ohm terminal and the XFMR terminal. Connect the speaker (or speakers) from the GND terminal to the 4 ohm terminal.

Also provided are 8 ohm, 25 volt, and 70 volt balanced outputs. To use these outputs, the jumper between 4 ohm and

XFMR must be installed. For 8 ohm speaker systems, connect between the COM terminal and the 8 ohm terminal. For

"distributed" speaker systems, 25 volt and 70 volt outputs are provided. One more output is provided on the UMA

Series amplifiers. This is a balanced, transformer-isolated line level output. This output is provided for direct connection to booster power amplifiers, etc. This output is designed to deliver 1 V RMS into a 600 ohm load. See Figures 4 through 7 for possible output connections.

NOTE: Due to the high gain and frequency response of the UMA Series amplifiers, it is necessary that the input cables be routed away from the output cables to prevent instability.

AC OUTLET (UNSWITCHED) (30)

Provides AC power for auxiliary equipment with power consumption — 300 watts maximum.

FUSE (31)

The fuse is located within the cap of the fuseholder. If the fuse should fail, IT MUST BE REPLACED WITH THE

SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOID-

ING THE WARRANTY. If the amp repeatedly blows fuses, it should be taken to a qualified service center for repair.

WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCON-

NECTED FROM ITS POWER SOURCE.

LINE CORD (120 V PRODUCTS ONLY) (32)

For your safety, we have incorporated a three-wire line (mains) cable with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the equipment without proper grounding facilities, suitable grounding adaptors should be used. Less noise and greatly reduced shock hazard exist when the unit is operated with the proper grounded receptacles.
