10. Do not use this amplifier if the power cord is broken or frayed. Protect the power cord from being walked upon or pinched particularly at the plugs and the point where it exits from the apparatus. 11. Only use accessories specified by the manufacturer. 12.

3. Clip/limit indicator This indicator signals when the amplifier output is clipping or limiting. It has two different indication states: If the clip limiter is engaged, it has a short time constant and it illuminates briefly. (See page 13 ). If the clip limiter is not engaged, it has an increased t...

8. Gain switch channel A . Three of the switches in the DIP-switch selects the maximum gain of the channel to be either 20, 23, 26, 29, 32, 36, 39 or 41 dB. (See page 6 ). 9. AC power cable. WARNING! A label just below the mains cable on the rear of the amplifier indicates the AC mains voltage, for ...

5.2 Link switch The Link switch located on the rear panel (the central DIP-switch) is for changing the operation mode of the amplifier (see below, section 5.3). 5.3 Operation modes 5.3.1 Stereo mode In this mode, both channels operate independently of each other. This is used for all 2-channel modes...

5.3.5 Bridge mono mode features Bridged mono mode combines the power of both channels into one speaker. This results in twice the voltage swing, four times the peak power and just less than three times the full power of a single channel. One way to understand the load and power from the amplifier’s ...
