Page 5: Operation
CA-8320 Powered Mixer Operation Make certain that speakers and input sources are properly connected before switching Keep volume levels at minimum gain and equalization set to 0dB position before switching on. When the AC Mains power switch is pressed, this unit starts operation with tuner display. -

Tape In Section Aux In Section 10. Tape In Control This knob provides control of the level of signal sent from the Tape In jacks to the Main L/R buss. 11. Aux In Control This knob provides control of the signal level sent from the Aux In jacks to the Main L/R buss. -
Page 10: Monitor Section
Monitor Section 12. Monitor Graphic Equalizer Each slider controls the cut (decreased gain) or boost (increased gain) for its associated frequency band in the MONITOR section. The middle position indicates flat response (no cut or boost). Moving the slider upwards increases that frequency’s gain, while moving it down decreases the level of that frequency. -

Main Section 16. Main Graphic Equalizer Each slider controls the cut (decreased gain) or boost (increased gain) for its associated frequency band to the Main L/R buss. The middle position indicates flat response (no cut or boost). Moving the slider upwards increases that frequency’s gain, while moving it down decreases the level of that frequency. -

The Main/LR Amplifiers are bridged (combined) to deliver a mono signal ONLY from the Bridge jack. 21. Power Indicator This LED indicator is lit when the AC mains to the CA-8320 is switched on. 22. Phantom Power Switch This switch activates the phantom power supply for channels 1-6. When the switch is switched on, +48VDC power is supplied to pins 2 and 3 of each channel’s input connector. - Page 13 CA-8320 Powered Mixer 25. Protection Indicator This LED indicates the state of the amplifier’s protection circuitry. When the Protection LED is on (illuminated), the protection circuitry is active, indicating that the unit is not operating normally. This is typically due to overheating or power...

Page 14: Input/Output Section
Input/Output Section 1. Channel Inputs 1-6 Each channel provides a high impedance (“high-Z”) input on a balanced 1/4” tip-ring-sleeve connector for line-level devices (synths, drum machines, etc.), and a low impedance (“low-Z”) input on a balanced 3-pin XLR jack for mic-level sources such as condenser and dynamic microphones. - Page 15 2. Channel 7 & 8 Inputs MIC INPUTS Both channels are active balanced, eliminating input transformers while maintaining the RF and hum rejection of transformer coupled circuits. Nominal input level: -50dB to –20dB. IMPORTANT: When a mic (or equivalent 150 Ω source) is NOT connected to these inputs, be sure the channel volume level is set to “0.”...

Rear Panel Controls 1. Speaker Output Jacks The CA-8320’s design provides up to 200W per channel to the Main L and Main R stereo outputs, or 400W using the Bridged (mono) output jack. The separate Monitor outputs deliver a maximum of 200W per channel. -
Page 17: Connections
CAUTION: When connecting devices to your CA-8320, avoid using non-standard plugs and cables. Speaker Connection The diagram below presents three approved CA-8320 speaker setups. Please take notice of the speaker impedance (Ω) requirements of each and be careful to avoid impedances lower than those specified. - Page 18 CA-8320 Powered Mixer The diagrams below present the approved impedance ranges for connecting speakers to one or both MONITOR A/B outputs. Please be careful to avoid impedances lower than those specified.

Page 21: Application-Specific Setups
Powered Mixer Application-Specific Setups For simple CD playback, a band PA, or a conference PA/installed sound system, see the following CA-8320 sample setups. Conference PA/Installed Sound System In the POWER AMP section, set the power amp mode to STEREO. Connect mics to channels 1-8. - Page 22 To record the sources connected to your CA-8320, connect the input of your recording device to the REC OUT jacks of the CA-8320. To Play Back a CD Switch the power on to the CD player and then to the CA-8320.

Connect the monitor speakers to the Power Amp Monitor A/B jacks. To connect an external processor such as a delay unit, connect that unit’s input to the CA-8320’s Effect Out jack. Then connect the unit’s output to the CA-8320’s AUX IN jack. - Page 24 Adjust the input level of the external effects device so it gets enough level but doesn’t distort. Use the CA-8320’s AUX IN control to adjust the level returning from the external effects device to the CA-8320’s effects buss.
