FRONT PANEL CONTROLS 1. Rack Mounting Ears Two front panel mounting holes are provided on each mounting ear. 2. Fan Vent CV-5000 amplifier is cooled by two rear-mounted fans. Cool air flows through the front fan filters, reducing the temperature of the inside components while forcing the heat out the rear vents. Never block these vents and keep them clean at all time. 3. AC Power Switch This switch controls the unit’s main power. 4. Signal Indicators These green and yellow LED

7. Protect Indicators These red LED indicate that the channel is in Protect mode. When the channel goes into protect mode all output for that channel will turn off by output relay. The protect LED will light when overheating or other severe problems occur. This is to protect any speakers connected to the channel. These LEDs light for approximately five seconds whenever the amplifier is powered on, and fade slowly when the amplifier is powered off. This is normal operation. 8. Channel input

REAR PANEL CONTROLS 1. Fan This is a variable speed cooling fan. Cool air enters the amplifier through the fan ports located on the front of the amplifier chassis, be sure not to block these ports when installing the amplifier or other associated equipment. 2. Input connectors Connect the input source to these electronic balanced Combination connectors using either XLR or 1/4” TRS plugs. The 1/4” TRS and XLR plug configured as follows: Pin 2 (Tip) hot, Pin 3 (Ring) cold

5. Limiter switch When the input signal connected to your amplifier is too high, you can end up with a distorted output signal. To prevent this, both channels of your CV-5000 feature a clip limiter that can be engaged or disengaged selectively. 6. Bridge / Stereo / Parallel switch This switch changes the amplifier operating mode from either stereo or mono, and bridged or parallel. You can place this switch in “STEREO” position (center) for normal stereo operation. When placed in “PARALLEL

PROTECTION The CV-5000 incorporates protection features. The front panel Protection LED indicates the activity of the relay speaker connection circuitry in each channel. When the Protection LED turn on, this circuitry is active and all connected speakers are muted. Initial Power Up - For approximately five seconds after initial power-up, the protection circuitry is activated and the speaker outputs are muted. If everything is operating normally, you will hear an audible click a

SETUP Cl ip Limiter Clipping is the result of an amplifier running into a power supply limitation. The maximum output voltage that any amplifier can produce is limited by its power supply. Attempting to output a voltage (or current) level that exceeds the power supply results in a “flattenin” effect on the signal, making it’s waveform look cut off or “clipped”. A clipped waveform exhibits extreme harmonic distortion, dominated by large amplitude odd-ordered harmonics and m

Mode Select Stereo Mode In stereo mode, both channels operate independently, with their input gain controls. Signal at channel 1’s input produces output at channel 1, while signal at channel 2’s input produces output at channel 2’s output. Recommended minimum nominal load impedance for stereo operation is 2 ohms per channel. Parallel Mode When set to Parallel mode, a signal applied to channel 1’s input will be amplified and appear at outputs for both channel 1 & 2. With set
