WARNING FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY BEFORE YOUR INITIAL START-UP! CAUTION! Keep this equipment away from rain, moisture and liquids.
IMPORTANT: The manufacturer will not accept liability for any resulting damages caused by the non-observance of this manual or any unauthorised modification to the equipment. • Never let the power-cable come into contact with other cables. Handle the power-cable and all mains voltage connections with particular caution! • Never remove warning or informative labels from the equipment. • Do not open the equipment and do not modify the equipment.
This 100V line slave amplifier was designed specifically for use in permanent audio installations, where reliability and premium sound quality are a must. Highly rugged construction and high efficiency design make this amplifier perfect for continuous duty applications in situations were power will be left on for indefinite periods of time. This 100V line amplifier is warranted from defects for one year from the date of purchase.

Identification: 1. Power LED - This LED will light up once the amp is switched on 2. SIGNAL LED - This LED will light up when signal is being received 3. CLIP LED - This LED will flash when the output signal starts to distort. A this point turn the master volume anti-clockwise to prevent damage. 4. PROT LED - This LED will illuminate when the unit goes into protect mode. Switch off the amplifier and check the output connections for faults or short circuits before powering on and resuming operation. 5.
Connections To The Mains Before connecting the amplifier to the local mains voltage outlet should be checked to ensure the available supply is 240V~AC 50Hz. This product is CLASS1 and requires a protective mains earth to be connected at all times. DO NOT remove or disconnect the earth. Power On/Off Procedure After connecting your amplifier to the mains, turn all controls counter clockwise to the “min” position.

Loads presented to the amplifier must be equal to or greater than listed above. Speaker impedances must be measured using a true impedance meter, do not standard multimeters.
Connection With The Mains Connect the unit to the mains via the IEC mains inlet using the 13A UK - IEC cord supplied. The earth has to be connected. Switch the unit on. After switching on the speaker system, wait 8 - 10 seconds before you turn the volume control up in order to avoid speaker damage. CAUTION! Increase the level of each channel up to the point where the clip LEDs illuminate. Always check the sound pressure level with a meter in order to keep to the legal threshold.
Problem Chart PROBLEM CAUSE REMEDY No Power The power cord is not connected Check the power cord and any No Sound The power cord of the respective product is not connected properly or not at all. Check the power cord and if the plugs are properly connected with the sockets. The connection socket or the plug is dirty. Clean the socket and/or the plug. Noise The input signal is too strong Reduce the input signal via the gain control.
