Cerwin-Vega CVA - 28 User Manual

A)  Power Indicator:  Illuminates when the system is powered  

 on.

B)  Limit Indicator:  Illuminates when the protection limiter is  

 active.

C)  Protect Indicator:  Illuminates when the amp has shut    

 

down to protect its self. 

D)  Signal Indicator:  An audio signal is present at the input.

E)  Power, On/Off:  Switches system on and off.

F) Voltage Switch: Allows system to be used with 

 

supply voltages of either 110-120 volts or 220- 240 volts.

G) AC Output: Intended to run power to one or two 

 

additional CVA-28 units.  NEVER daisy chain more than  

 

three CVA-28’s from a single source!

H)  AC Input: Input for attachment of an IEC power cord    

 

I)  FUSE: Be sure to use the correct value and rating  

 

 

fuse for the voltage selected!

J)  Level Control:  Adjusts the input signal to the amplifi er.

K) 

Line/Mic: Balanced and unbalanced signals are 

  supported on both the XLR input connector and the 

  quarter inch input connector. Allows input to accept 

 

either a line level or a mic level signal. Mic/DI is for a   

 

microphone or instrument direct input. Line is for a line  

 

level output from an audio source such as a mixing board

L)  No Sub/Sub:  Use the “No Sub” position when a  

 

dedicated subwoofer is not being used.  This position  

 

 

provides more bass for full range use.  Use the “Sub”   

 

position when a dedicated subwoofer is used. This  

 

 

position reduces some low frequency information that   

 

may interfere with your subwoofer frequencies creating a  

 

“muddier” or less-defi ned sound. Experiment with this   

 

control for the best results. Removal of these bass  

 

 

frequencies also allows the CVA-28 to play louder.

M) Off/Contour: Provides an alternate internal equalizition  

 

circuit that reduces mid range.  Setting this switch to the  

 

On position when playing the CVA-28 at high volumes  

 

will reduce mid range frequencies for a more even 

 response.

N) THRU: This THRU signal bypasses the controls and is a  

 

buffered output of the IN signal. Allows the signal at IN  

 

to be routed to another CVA-28. Note that you must set  

 

up the controls on each CVA-28 independently.

O) IN: Balanced XLR and 1/4 inch TRS connectors accept  

 

signals from balanced or unbalanced line level or Mic  

 

level sources. Signal at IN is bufferred and routed to    

 Thru.
