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.

Warning: Do not plug system into a 220-240 volt circuit while switch is in the 110-120 volt position. Be sure to use the correct value and rating fuse for the voltage selected!

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 amplifier.

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-defined 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.
