GUIDELINE TO OPERATE THE AMPLIFIER

1.  Place the Amplier in dry and well ventilated place. Considerable heat is generated inside the amplier during 

continuous use, therefore do not block the top cover ventilation holes by placing anything on top of the amplier.

2.  Only good quality Low impedance microphones like 5 CORE 5CM-ND 780X, ND 99X or ND series to be used to 

avoid / reduce feedback & howling. This will help obtaining satisfactory power output from Amplier without 
howling or feedback.

3.  Driver Units, Columns Speakers & Box speakers give best performance and are safe from damage when fed with 

up to half of their handling capacity. This is because these have to handle certain peak music signals and 
transients which may be two to three times higher than the power wattage being fed to these by Amplier.

4.  It is advised to keep the master Control of the Amplier at’0’ position before switching ‘ON’ the Amplier & later 

may be moved to optimum position say ‘6 to 8’.

      CAUTION
The equipment must be earthed properly before operating it to avoid electric shock. A wire from the Earth terminal 
must be connected to either water pipe or to electrical earth for safe operation.

SPEAKER CONNECTIONS

Low impedance Speaker Connections
Speaker impedance taps of 4Ω, 8Ω & 16Ω have been provided at the rear. Always use 23/38 or thicker speaker cable 
to reduce power loss in the cables. Make proper matching speaker connection as explained below.

Correct Phasing of Loudspeakers

• 

When two or more speakers/Units are installed in the same area and are facing the same direction, it is essential 
that their Cones/ diaphragms act in unison. Otherwise the sound level of one speaker will be cancelling the sound 
level of the other. To avoid any mistake, the terminal of Box Speakers and the driver unit are marked ‘+’ & ‘-‘. 
Always connect the COM of the amplier to ‘-‘ of Speaker and 4Ω/8Ω/16Ω of the ‘+’ of the Speakers.

• 

In case of LMTs the COM of all the LMTs should be connected to the COM of the red terminal strip of the Amplier 
and the Power tap to 70V/100V lines as shown in gure.

      CAUTION
• 

When 70V/100V line is being used, no Speakers / driver units should be connected to 4Ω/8Ω (low impedance) tap.

• 

Loudspeaker / driver unit should be connected to either COM-4Ω, COM-8 Ω, COM-16Ω, COM-70V, COM-100V 
terminals, but never to more than one set of terminals.

Safety Instructions

•  WATER AND MOISTURE: In order to prevent any re or shock hazard, do not expose this equipment to rain or 

moisture.

•  POWER SOURCE: The equipment should be connected to a 220-240V 50/60Hz or 12V DC power source.
•  POWER CORD PROTECTION: Do not cut, kink, damage or modify the power cord supplied with the equipment, 

keep the power supply cord away from heaters and harmful chemicals. Do not place heavy objects on the power 
cord.

•  Operation on Generator: When operating the Amplier on a generator, make sure it is switched ‘OFF’ till the 

generator voltage has stabilized and then only switch the amplier ‘ON’.

•  VENTILATION: The amplier should be situated so that its location or position does not interfere with its proper 

ventilation, Also do not insert or drop anything into the ventilation holes.

•  PREVENTION OF LOSS IN SPEAKER CABLES: Always use thick cables for low impedance speakers 

connections, Use of cable type 23/38 or thicker is recommended as heavy current ow through the cables.

•  PROPER SELECTION OF OUTPUT TERMINALS: When 70v/100V line is used, do not connect speakers 4Ω/8Ω/16Ω 

(low impedance) tap. Similarly do not connect speakers to 70V/100V line when 4Ω/8Ω/16Ω tap is being used.

•  GROUNDING OR EARTHING: The equipment must be earthed properly before operating it to avoid electric shock. 

A wire from the earth terminal must be connected to either water pipe or to electrical earth for safe operation.
