UNDERSTANDING THE INPUT FUNCTIONS

SETTING THE VOX AND MUTE JUMPERS

DUAL VOX AND DUAL MUTE - The Amplifier provides two independent 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.
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.

Turn Attenuator (rear panel) fully counterclockwise.
Turn INPUT 5 Front Panel Control to midway.
Switch Amplifier and Music Source ON.
Turn Attenuator Control (rear panel) until desired Output
Level is achieved.
Adjust INPUT 5 Front Panel Level Control Up-Down as
desired.
STEREO SUMMING
Most Music Source Devices provide a Stereo Output.
Accordingly the Amplifier is equipped with two Jacks for the
AUX 1 Input (L and R). The two Inputs are internally
buffered and electronically mixed to Mono. This system
ensures that the Music Device is properly loaded and that
the Stereo Signals are correctly summed (L+R) to Mono
without distortion.
CABLE
To connect the music source devices to the AUX 1 Input
use two single conductor shielded audio cable terminated
in a single prong phono plug on both ends.

DUAL MUTING SYSTEM - The Amplifier is equipped with a DUAL
noiseless, fast acting Logic MUTING Switching System. When any
of the INPUTS are activated and a Signal is present on a given
INPUT and either VOX 1 or VOX 2 or BOTH are Switched-ON
(using internal Jumpers) then the MUTE 1 or MUTE 2 BUSS or
BOTH are ACTIVE. If any of the INPUTS have the MUTE 1 or
MUTE 2 Switched-ON (by Internal Jumpers) then the INPUT (or
INPUTS) will be MUTED according to the Jumpers Setting. Once
the SIGNAL-ON on the ACTIVE INPUT is terminated the normal
functions are automatically restored on all muted inputs.

DIRECT MUTING - Direct Muting may be accomplished by shorting the MUTE 1 and MUTE 2 Terminals to the G Terminal through
an external switch. Each time the Muting Switch is closed the corresponding MUTE BUSS is activated.

INSTALLATION TIPS
1) Use high quality, short length audio cables and position
the Equalizer in close proximity to the Amplifier. Avoid
mounting the EQ on top of the Amplifier unless is Rack
mounted.
2) Be sure that the Amplifier input controls and the EQ level
control are set at zero prior to turning the system On.
3) The Amplifier TONE BY PASS SWITCH (Reference 17)
should be set to ON ( linear response position).
4) Carefully adjust the EQ Level Control to avoid distortion
caused by excessive signal boost.
5) Follow the instructions supplied with the Equalizer.
WIRING
To connect to an External Equalizer use two (2) single conductor shielded audio cables terminated in a single prong
phono plug on both ends.

REMOTE VOLUME CONTROLS
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 resistance exceeds 3 K ohm the Volume may not go down to zero.

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 adjusted 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.

AUTO SERVICE STATION C - STORE - APP. DATA 123
APPLICATION
This Note illustrates a typical Auto Service Station
C-Store application. The size of the Service
Station and the number of Gas Pump Islands to
cover will determine the amount of outdoor
Waterproof Speakers required and the Power
Output of the Amplifier.

GAS PUMP OUTDOOR SPEAKERS
40 WATT SYSTEM EXAMPLE - The PASO Model
C55DMST Waterproof Music Speaker is recommended. Typically each Speaker should be tapped
at 5 Watt. In this configuration up to 8 Speaker
may be used with the Model DMS3040 40 Watt
Amplifier for distribution of Music and Messages
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 utilizing the separate (2) 1 Watt Amplifiers as a first
and second zone, only the Music program will be
distributed inside the Store. This avoids the continuous and annoying repeating of the messages
in the indoor areas. The output level may be
adjusted by the 1st and 2nd Zone Level Control.

ZONE 1 - ZONE 2 PROGRAM SOURCE SELECTOR
The program Source for each Zone Output may
be selected by setting the Zone 1 and 2 Jumper
Set to either AUX 1 - AUX 2 or Module Source.

MUSIC ON HOLD
The Zone 1 Amplifier provides a separate 600
ohm Transformer Balanced Music on Hold Output
for the Telephone system. If the Zone 1 Input
Select Jumper Set is set to AUX 1, the MOH
Output receives the Music from the Satellite
Receiver without Paging or Messages interruptions.

PAGING MICROPHONE
PRIORITY PAGING MICROPHONE - A Low
Impedance Dynamic Microphone can be connected to the Amplifier INPUT 1. The Microphone can
be set to provide Priority Paging over both the
Music Program and the Message Repeater.
Optionally Paging may be generated from the
Phone system if desired. The TEL INPUT provides
a 600 ohm Transformer balanced Phone interface.

MESSAGE REPEATER
The Message Repeater provides pre-recorded
Messages at the Gas Pumps Only. Each time a
message is initiated by the Repeater (AUX 1) the
Music (AUX 2) is automatically muted for the duration of the message.

REPEATER REMOTE VOLUME
A Master Remote Volume Control PASO Model
RVC10W may be provided to adjust the Output
Level of the Message Repeater in accordance to
the outdoors noise.
