CERWIN-VEGA! PROFESSIONAL ACTIVE SERIES

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	= the system is being driven to its maximum capacity (clipping)
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” phone 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 signals 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 coming in on the L and R inputs. The High Pass filter is active on these outputs. These outputs and the High Pass filter are 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 opera- tional. 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.)

PARAMETRIC EQUALIZER (CVA-121 only): one band full parametric equalizer with adjustment of the Gain, Frequency, and Q. The higher the setting, the narrower the frequency range becomes that is being affected.

POWER SWITCH: turns the AC power of the unit on and off.

AC INPUT: input for attachment of the IEC power cord.
