Rear Panel

4. Input 2

Input 2 can accept more than one type of audio signal. This input section has a 3 position Phoenix connector for Mic or Line input

signals and a 3.5mm stereo jack that is summed. The level to the amplifier mix is controlled by Input 2 level located on the front panel.

Note: Only one type of input signal can be applied at one time.

Balanced Mic / Line - Balanced Microphone or Line level signals connect to the (+), (–), and (G) terminals. To select between

Mic or Line input levels, refer to the DIP switch chart on the rear of the amplifier for feature assignment. If connecting an

unbalanced line level input, tie (short) the (G) and (–) terminals together for negative or ground connection and the positive or

(+) signal to the (+) terminal on the amplifier input. If the input is used in Mic mode, Phantom power for condenser type

microphones is available in the DIP switch settings on the rear panel.

Input 2 Stereo Summed - Input 2 consists of stereo 3.5mm summing inputs, suitable for connection to the output of iPod

CD/DVD players, etc.

5. Input 3

Input 3 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.

6. Input 4

Input 4 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.

7. Remote Mute Connector

Shorting the Remote Mute terminals will mute the inputs that are assigned to receive the mute command. When an input is set to

Mute Receive via the corresponding DIP switch, the input associated to the switch will be muted when terminals (G) and (M) are

shorted together. This connection is usually done via remote switch on a microphone.

8. VOX Mute Sensitivity Control

Input 1 signal can be used to trigger or activate a mute command. When an input is set to Mute Receive via the corresponding DIP

switch, the input associated to the switch will be muted when a signal is applied to Input 1. The VOX Mute Sensitivity Control adjusts

how sensitive the mute circuitry from Input 1 reacts. Setting the control fully counter-clockwise will lower the sensitivity, where a

higher amplitude signal will be required at Input 1 to trigger the mute send circuits. Fully clockwise will raise the sensitivity of the mute

circuits, where a lower amplitude signal will trigger a mute send. Calibration of this control in conjunction with the microphone to be

used is very important to assure the proper amount of signal from the mic is enough to trigger the mute circuits. If it is not calibrated

properly, the mute may not be triggered when a weak voice vs a strong voice uses the mic.

9. Zone 2 Output Port

This terminal provides a 600Ω unbalanced output that is typically connected to a PBX music on hold port, also known as MOH. Inputs

are assigned to the Zone 2 bus via switch associated with the input. Note: 10kΩ output impedance is available via the internal shunt

selection.

10. Zone 2 Output Level Control

This control will vary the level at the Zone 2 output terminals. Fully counter-clockwise (0) is off, fully clockwise (10) is the maximum

output level. The Zone 2 level control is PRE Inputs 1, 2, 3 and 4 volume controls.

11. Remote Input Select (RIS) Port

Inputs 2, 3 & 4 can be remotely activated or selected. When any of the RIS input control port pins are shorted to ground, the signal

from that input selected will be routed to the amplifier main mix bus. The RIS control port was designed to work with the Atlas Sound

WPD-RISRL accessory item. See "Remote Input Selection and Level Control" for operation.
