Signal input: Inputs (RCA or XLR) are for connecting a preamplifier to your amplifier. It is designed to receive an 

analog 

signal (as opposed to 

digital 

signal). To connect your source we are using a traditional 

RCA 

cable, they are 

usually identified by a color code 

RED 

to the RIGHT channel and 

WHITE 

to the LEFT channel.

Speaker output: Connect speaker to the terminals.

Important Note

: Check the impedance of your speakers. When using a pair of speakers, you can use speakers 

with an impedance of between 4, 8 and 16 ohms. BE SURE TO USE THE MATCHING TERMINALS.

Power Socket with main fuse: Main fuse is located on the rear of the amplifier just below the power cord socket. 

Replace with the same type and value fuse. Once all connections to the amplifier have been made, connect the 

power cable to an electrical outlet and turn on the unit as it is ready for operation.
