Back Panel Controls, Connectors and Indicators
INDICATORS: Illumination of LED indicates status of amplifier.
Power: Electric current is live and present in the system
Limit:
This LED lights when the limiter is engaged to pre-
vent the amplifier from clipping. As a visual warn-
ing, it stays lit for a short period after the limiter has
turned off
Protect: The built-in amplifier has shut down to protect
itself
Signal: A line-level signal is present in the system
IN L & R inputs: Electronically balanced XLR and 1/4" phono
connectors accept input signal from line-level sources. IN L & R
also routes to THRU L & R outputs.
LEVEL: Controls the master volume at the pre-amp stage.
HIGH PASS FILTER: When sending a full range signal
through the subwoofer to top cabinet, the HPF blocks LF sig-
nals below
indicated frequencies from reaching the top cabinet.
VARIABLE LOW PASS FILTER: When sending a full range
signal to the subwoofer, the variable LPF blocks HF signals
above indicated frequencies from reaching the subwoofer.
THRU L & R outputs: Provide a loop-thru of the signals com-
ing in on the L and R inputs. The High Pass filter is active on
these outputs. These outputs and the High Pass filter area
always active regardless of whether the unit is in master or
slave mode. Typically these outputs are used for top cabinets.
POLARITY SWITCH: Changes the polarity of the subwoofer,
also referred to as the "phase". Listen and adjust for maximum
bass.
MASTER/SLAVE: This mode is used to provide the ability to
adjust multiple sub units from the master sub. When switched
to MASTER, all sub controls are functional and both L and R
inputs are operational. The LINK OUT connector sums the
input signals from both L and R inputs and is used to send a
signal to a sub in SLAVE mode. When set to SLAVE mode, only
the L input connector is active and the LEVEL, POLARITY, and
LOW PASS FILTER are inactive. To attach more subs, set them
to SLAVE mode, use the LINK OUT of the previous sub, and
send this signal to the L IN on the SLAVE.
LINK OUT: Used to send a signal to a sub set to SLAVE mode.
When the sub is set to SLAVE mode, the LINK OUT provides a
summed signal of the L and R inputs. (See MASTER/SLAVE for
more information.)
POWER SWITCH: Turns the AC power of the unit on and off.
AC INPUT: Input for attachment of the IEC power cord.
