CONTROLS

Input L, Input R

Electronically balanced inputs for the connection of LINE-

level signal sources such as mixers, signal processors,

etc. Establishing a connection is possible via phone or

XLR-type plugs. Whenever possible, balanced signal feed

is always preferable to guard against potential noise or HF-

interference.

Caution: Before making any connections or

disconnections, make sure to set the corresponding

level controls to their counterclockwise stop.

The input section of the PowerSub 312 also allows Mono-

Sub operation. The stereo signal needs to be fed to the L

and R inputs and the low-frequency range signals of both

channels are summed prior to being processed in the

power amplifier section. All other applications employ only

the (L)/Mono input.

Parallel Outputs L/R

Connected in parallel to the input jacks, these connectors

are used for "carrying through" the input signal.

CLIP indicates, when lit, that the internal power amplifier

is actually operated in the border range before clipping.

Short-term blinking is uncritical, because the amp's audio

limiter keeps distortion under control leaving the sound

unaffected. Constant lighting of this indicator signals

that the input section is probably overdriven and sound

degradation could be the result. Lowering input levels can

prevent input clipping before it occurs.

SIGNAL

Indicates that an audio signal is present at the input and

that it is output as well.
