CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK DO NOT REMOVE
COVER. NO USER SERVICABLE PARTS
INSIDE. REFER SERVICING TO
QUALIFIED PERSONNEL!
The lightning flash with arrowhead symbol within an
equilateral triangle is intended to alert the user to
the presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.
The exclamation point within an equilateral triangle
is intended to alert the user of the presence of
important operating and maintenance (servicing)
instructions in the literature accompanying the
appliance.

provide many years of dependable service and reliable sound reproduction.
Please read this entire manual, especially the Safety Warnings, before operating your
amplifier.
UNPACKING AND PAPERWORK
Carefully unpack the amplifier and keep the original carton and packing materials for future
moving, shipment or long-term storage. After opening the box, please check for visible signs
of damage that were not apparent from the outside of the box. If you encounter what appears
to be concealed damage, please contact your Carver Professional Dealer before installing
unit.
Important Paperwork
Make sure to save your sales receipt. Your receipt is extremely important to establish the
duration of your Limited Warranty and for insurance purposes. Next, make a note of the
serial number, which is located on the back of the amplifier. Record it in the space provided
below for convenient reference.
Model: _______________ Serial Number: __________________________
Purchased at: __________________________ Date: _________________
Finally, take a moment to fill out the Warranty Registration Card packed with the amplifier and
return it to Carver Professional. This will allow us to keep you informed about new products,
as they become available

CONTROLS AND FUNCTIONS
1. Rack Mount Ears
The ears for rack mounting the CV Series amplifiers are removable. If your installation does not require rack
mounting, the rack ears can be removed, however the screws that fasten the rack ears to the chassis should
be replaced to maintain the chassis’ structural integrity.
2. Level Controls
The Level Controls on the CV Series amplifiers utilize a DC voltage to control the output level of the CV
Series amplifiers through a VCA (voltage controlled amplifier). The knobs can be removed and replaced with
black plastic caps provided with the amplifier. Before installation of the plastic caps, be sure to set the
maximum level that you will need for each channel or zone. Once the caps have been installed they are
difficult to remove.
3. Status LED Display
The READY (Green LED) indicates that the power-up process has completed, and the amplifier is
operational. PROTECT (Red LED) indicates that the CV Series amplifier has detected a fault (over-current,
over-voltage or short circuit, and has placed itself into a protect mode. Check all connections and level
settings for a problem. THERMAL (Red LED) indicates that the CV Series amplifier has exceeded the
maximum allowable operating temperature. The CV Series amplifier will restart as soon as the power
transformer or heat sink has reached a safe operating temperature.
4. Level Display LEDs
Five LEDs per channel or zone, display the signal level of the CV Series amplifier. SIGNAL LED indicates
there is signal at the input of that channel or zone. The -20dB LED indicates a signal at the output of 20dB
below rated output. The –12dB LED indicates a signal at the output of 12db below rated output. The –6dB
LED indicates a signal at the output of 6dB below rated output. The CLIP LED indicates a signal at the output
that exceeds the rated output of the amplifier. NOTE: It is normal to operate the CV Series amplifier so that
the CLIP LED illuminates (Red) at the loudest peaks of the information being reproduced. If the Clip LED is
staying on continuously, or for extended rather than momentary intervals, levels in that channel or zone
should be reduced to avoid driving the amplifier into over-voltage or over-current conditions.
