Cerwin-Vega! CXA - AMPLIFIER SERIES CXA AMPLIFIER FRONT PANEL DESCRIPTION Figure 1.1 1. Fan Vent The CV-Series amplifiers are cooled by two rear-mounted fans (except for CV-900 which is cooled by a single rear mounted fan). Cool air flows through the front fan filters, reducing the temperature of internal components while forcing the heat out the rear vents. Never block these vents and keep them clean at all times. 5.
Cerwin-Vega! CXA - AMPLIFIER SERIES CXA AMPLIFIER REAR PANEL DESCRIPTION Figure 1.2 1. Fan This is a variable speed cooling fan. Cool air enters the amplifier through the fan filters located on the front of the amplifier. Be sure not to block these ports when installing the amplifier or other equipment. 2. Input connectors Connect the input source to the unbalanced RCA connectors using standard RCA cables. 3. Link connectors These jacks are used to send a parallel signal to another device or amplifier. 4.
PROTECTION Every model in the CV-Series incorporates protection features. The front panel Protection LED indicates the activity of the speaker connection relay circuitry in each channel.When the protection LED turns 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.
SETUP (CONTINUED) CONNECTIONS Mode Select Stereo Mode (5-Way Ouptut Binding Posts) Stereo Mode In stereo mode, both channels operate independently with individual 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.
