Controls - Dynacord PowerSub 312 Owner's Manual

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.
