Mains Switch

Use the mains switch to switch the unit’s power on. A soft-start function prevents inrush current peaks on the mains, additionally preventing the mains line protection switch from activating during the amp’s power-on operation. Loudspeaker outputs are activated via relay switching with a delay of approx. 2 seconds, which effectively eliminates eventual power-on noise.

During this delay period, the Protect LED lights to confirm correct operation of the protection circuitry.

Protect (PROT)

A lit Protect LED indicates that one of the integrated protections against thermal overload, short-circuit … has been activated. The audio channels’ protection circuits operate in- dependent from each other. At the occurrence of failure or overload conditions the affected power amp channel is separated from the load connected via output relay, preventing the connected loudspeaker systems and the power amplifier itself from being damaged. Whatever caused the fault – e.g. a short-circuited speaker cable – needs to be remedied. In case of thermal overload you have to wait until the power amplifier automatically returns to normal operation.

Limiter

The Limit indicator lights as soon as the integrated dynamic limiter is being activated and the power amp is driven at the clipping limit or generally at its maximum capacity. Short-term blinking is not a problem, because the internal limiter trims input levels of up to +21dBu down to a THD+N of approximately 1%. If, on the other hand, this LED lights constantly, reducing the volume is strongly recommended to prevent the connected loudspeaker systems from being damaged by probable overload.

Level Indication

The level indicators signify the power amplifier’s current modulation. The -30dB LED starts lighting at approx. 30dB below full modulation while the -10dB LED lights at approx. 10dB below full modulation. Shorted speaker cables or the activation of a protection circuit causes these indicators to go out.

Power

The Power indicator lights when switching the power amplifier on. If the power on LED does not light please check to make sure the unit is plugged in or that the primary fuse is not blown. If the fuse is blown please contact an authorized service center.
