UNPACKING

Immediately upon receipt of the amplifier, inspect the unit
and shipping container for indications of improper handling
or in transit damage. The equipment was carefully inspect­ed and tested before leaving the factory. Notify the
Transportation Company immediately if any damage is
found. ONLY THE CONSIGNEE CAN FILE A CLAIM WITH
THE CARRIER FOR DAMAGE DURING SHIPMENT. Be
sure to save the carton and packing material as evidence of
damage for the shipper inspection. DO NOT SHIP the unit
back to the factory unless authorized by the factory.

FUNCTION SWITCHES AND JUMPERS

UNDERSTANDING THE INPUT FUNCTIONS

VOX AND MUTE - The Amplifier provides an independent VOX
and MUTE SYSTEM

FUNCTION SOCKETS - EACH INPUT IS PROVIDED WITH A
VOX (V1) AND A MUTE (M1) SOCKET.

INPUTS VOX AND MUTE FUNCTION - All Inputs provide a VOX
SEND and a MUTE RECEIVE functions. The VOX and MUTE
functions are SWITCHED-ON, on each Input, by Internal Jumpers
provided for each Input.The VOX BUSS SEND (V1) and the MUTE
BUSS RECEIVE (M1) can be independently SWITCHED-ON or
OFF to suit the application requirement.

Fig. 8 - Any Input VOX and MUTE Functions

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.

The SOCKETS are located on the Main PCB inside the Amplifier
as shown on the SWITCHES and JUMPERS LOCATION DIA­GRAM 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.

TO SET: Lift the Jumper and reset as required. making sure that
the JUMPER is properly positioned over the two shorting pins.

The VOX JUMPER has two positions: OFF, and V1
The MUTE JUMPER has two positions: OFF, and M1

The figure below shows how the VOX 1 Logic Switch is switched
ON and the MUTE 1 Logic Switch is SWITCHED-OFF by moving
the Jumpers as indicated. When the Input is activated by a Source
signal the corresponding VOX Signal is sent to the V1 BUSS.
When the VOX 1 is activated by any Input the MUTE Signal is
present on the MUTE 1 BUSS and it will MUTE any Input with the
MUTE M1 turned on.

SETTING THE VOX AND MUTE JUMPERS

Fig. 8A - VOX and MUTE Sockets

IMPORTANT NOTE

BE SURE NOT TO SET BOTH THE VOX AND
CORRESPONDING MUTE ON THE SAME
INPUT OR THE INPUT WILL MUTE ITSELF
WHEN ACTIVATED.

EXAMPLE: INPUT 1 - V 1 and M 1 BOTH ON.

INPUT 1 - MICROPHONE INPUT

MICROPHONE TYPE

The Microphone Input accepts Low Impedance (250-600 ohm)
Dynamic Microphones. The Microphone may be a balanced output
type (three wire) or an unbalanced output type (two wire).

PASO MICROPHONES

All PASO low impedance Microphones have a balanced output for
best performance. Connect the RED lead to terminal HOT, the
WHITE lead to terminal COM and the SHIELD to terminal G.

WIRING

CABLE

MICROPHONE INPUT

Attach the microphone leads to the ter­minal strip as per diagrams at left.

DO NOT GROUND THE MICROPHONE
CABLE SHIELD TO THE CHASSIS OF
THE AMPLIFIER

BALANCED MICROPHONE

IMPORTANT NOTE: The use of an
unbalanced Microphone (two leads) is
not recommended. For best results in a
PA Application always use a
Unidirectional Dynamic, Low
Impedance, Balanced Microphone
(three leads).

UNBALANCED MICROPHONE

Attach the Microphone leads to the ter­minal strip as per diagram in Fig 10A.
The cable length should not exceed: 15
Ft. (4.5 m).
