UNDERSTANDING THE INPUT FUNCTIONS

SETTING THE VOX AND MUTE JUMPERS

DUAL VOX AND DUAL MUTE - The Amplifier provides two inde-

pendent VOX (V1 & V2) and two MUTE (M1 & M2) SYSTEMS

JUMPER SETTINGS - The VOX and MUTE Functions are

SWITCHED-ON or OFF by setting the JUMPERS on the VOX (A)

and MUTE (B) SOCKET. See Fig. 8A.

FUNCTION SOCKETS - EACH INPUT IS PROVIDED WITH A

VOX (V1 & V2) AND A MUTE (M1 & M2) SOCKET.

The SOCKETS are located on the Main PCB inside the Amplifier

as shown on the SWITCHES and JUMPERS LOCATION DIA-

GRAM in this Manual. Each Socket is identified by an ID NUMBER

and the FUNCTION and DEFAULT settings are listed on the

FUNCTION SWITCHES and JUMPERS DEFAULT SETTING

TABLE in this Manual.

INPUTS VOX AND MUTE FUNCTION - All Inputs including the

Module provide 2 - VOX SEND and 2 MUTE RECEIVE functions.

The VOX and MUTE functions are SWITCHED-ON, on each Input,

by Internal Jumpers provided for each Input. Two VOX BUSS

SEND (V1 & V2) and two MUTE BUSS RECEIVE (M1 & M2) can

be independently or simultaneously SWITCHED-ON to suit the

application requirement.

TO SET: Lift the Jumper and reset as required. making sure that

the JUMPER is properly positioned over the two shorting pins.

The Amplifier features two independent Remote Volume Control Capability: The INPUT 4 (AUX 1) Remote Volume (Reference 26) and

the MASTER REMOTE VOLUME CONTROL (Reference 11). A 10 K ohm Potentiometer is required for either control. Mount the 10 K

Pot on a suitable Wall Plate or any other convenient surface and connect to the Amplifier RVC Terminals as shown in the Diagram. The

Paso Model RVC10W Decora Style Remote Volume Control may be used.

INPUT 4 (AUX 1) OPERATION

When connected the Remote Volume adjusts the INPUT 4 (AUX 1) Level only. Usually this input is utilized for the Music Source (Satellite

Receiver, CD Player, etc.).

MASTER VOLUME OPERATION

The Control is a Master Volume and controls all the Inputs of the Amplifier with the exception of the MOH and ZONE 1 and ZONE 2

Outputs.

CABLE

To connect the Remote Control to the Amplifier use a two conductor wire not less than AWG 24. While the Remote Volume System uses

DC rather than audio caution should be exercised in the layout of the wire. Always avoid routing next to power lines. If the total wire resist-

ance exceeds 3 K ohm the Volume may not go down to zero.

APPLICATION

This

Note

illustrates

typical

installation

Restaurant/Diner/Lounge using Background Music and a Jukebox.

The Background Music can be automatically interrupted when the

Jukebox is activated. The Background Music is then automatically

restored once the Jukebox stops playing.This built-in feature of the

DMS Amplifier eliminates the need of any external device.

PAGING MICROPHONE

PRIORITY PAGING MICROPHONE - A Low Impedance Dynamic

Microphone can be connected to the Amplifier INPUT 1. The

Microphone Input can be set to provide Priority Paging over both

the Music Program and the Jukebox if activated. Optionally Paging

may be generated from the Phone system if desired.

PAGING FROM THE PHONE SYSTEM

PRIORITY PAGING FROM THE PHONE SYSTEM - Paging may

be generated from a Phone System by using the TEL INPUT of the

Amplifier. The TEL INPUT can be set to provide Priority Paging

over both the Music Program and the Jukebox if activated.The TEL

INPUT provides a 600 ohm Transformer balanced Phone interface.

MUTE 2 DELAY

The Jukebox Configuration utilizes the VOX/MUTE 2 Buss. In order

to prevent the premature JUKEBOX/MUSIC SOURCE switching

(the Music Source cuts-in while the Jukebox is active) a MUTE 2

DELAY TRIMMER is available on the Rear panel to increase the

MUTE 2 DELAY as necessary. The MUTE 2 DELAY can be adjust-

ed from 3 to 30 Seconds.

EXAMPLE: If the Jukebox is playing and the Tune has a long pause

or the long pause while the Jukebox is cycling between CD’s it is

possible that the Music Source (Background Music) may cut-in

causing annoying and unwanted chatter while the Jukebox is still

active.To prevent this problem the MUTE 2 TIME DELAY should be

adjusted accordingly.

at the Gas Pumps.

For larger systems use a higher power Amplifier

and the additional quantity of speakers required.

C _ STORE INDOOR SPEAKERS

The Amplifier is equipped with two independent 1

Watt , 8 ohm Amplifiers = ZONE 1 and ZONE 2.

C-STORE - Up to 4+4 Ceiling Speakers may be

utilized indoors in the Store area, Rest Rooms or

other area such as a separate concession. By uti-

lizing the separate (2) 1 Watt Amplifiers as a first
