- Volume (Channel A / Channel B): Independent rotary controls for adjusting the output level of each channel.
- VU Meters: Two analog meters displaying the output level for Channel A and Channel B.
- Power Switch: Toggles the amplifier's main power on or off.
5.2 Rear Panel
Image 2: Rear view of the Avantone Pro CLA-200 amplifier, detailing the input/output connections, voltage selector, and mode switch.
- Voltage Select: Switch to select between 115V and 230V AC input voltage. Ensure this is set correctly for your region before connecting power.
- AC Inlet: Standard IEC power connector for the AC power cable.
- Inputs (XLR): Balanced XLR input connectors for Channel A and Channel B.
- Link (XLR): XLR output connectors that mirror the input signal, allowing for daisy-chaining to other amplifiers.
- Outputs (Speakon / Binding Posts): Speaker output connectors for Channel A and Channel B. Both Speakon and binding post terminals are provided.
- Mode Selector: Switch to select the amplifier's operating mode:
- Parallel: Both channels receive the same input signal from Channel A, driving two separate speakers.
- Bridge: Combines both channels into a single, higher-power mono output. Use only one speaker connected to the designated bridge output.
- Stereo: Each channel operates independently, with separate inputs and outputs.
6. Setup
Follow these steps to set up your CLA-200 amplifier:
- Unpacking and Placement: Carefully remove the amplifier from its packaging. Place the unit on a stable, level surface or install it in a standard 19-inch equipment rack. Ensure adequate ventilation around the unit; do not block any vents.
- Voltage Selection: Locate the Voltage Select switch on the rear panel. Verify that it is set to the correct voltage for your region (115V or 230V) before connecting the power cable. Incorrect voltage selection can cause severe damage to the unit.
- Input Connections: Connect your audio source (e.g., audio interface, mixer) to the XLR Input connectors on the rear panel using balanced XLR cables. For stereo operation, connect to both Channel A and Channel B inputs.
- Speaker Connections: Connect your passive studio monitors to the Output connectors. You can use either Speakon cables or standard speaker cables with the binding posts. Ensure correct polarity (+ to + and - to -) for all connections. For stereo operation, connect one speaker to Channel A outputs and another to Channel B outputs. If using Bridge mode, refer to the rear panel diagram for the correct single speaker connection.
- Mode Selection: Set the Mode Selector switch to your desired operating mode (Stereo, Parallel, or Bridge) based on your setup requirements.
- Power Connection: With the amplifier's front panel power switch in the OFF position, connect the supplied AC power cable to the AC Inlet on the rear panel and then to a suitable wall outlet.
- Initial Power On: Turn the front panel volume controls to their minimum (fully counter-clockwise) position. Then, press the Power switch to turn on the amplifier. The VU meters should illuminate.
7. Operating Instructions
Once the CLA-200 is set up, follow these guidelines for operation:
- Power On/Off Sequence: Always power on your amplifier after turning on your audio source and power off your amplifier before turning off your audio source. This helps prevent transient pops or thumps that could damage your speakers.
- Volume Adjustment: Slowly increase the Volume controls for Channel A and/or Channel B to achieve your desired listening level. Observe the VU meters to monitor the output signal strength. Avoid consistently driving the amplifier into the red zone on the VU meters, as this indicates clipping and can cause distortion and potential speaker damage.
- Monitoring: Use the VU meters as a visual reference for your audio levels. They provide an indication of the average signal level.
- Mode Usage: Ensure the Mode Selector switch is set correctly for your application. Changing modes while the amplifier is operating is not recommended. Power off the unit before changing the mode.
8. Maintenance
Proper maintenance ensures the longevity and optimal performance of your CLA-200 amplifier:
- Cleaning: Disconnect the power cable before cleaning. Use a soft, dry cloth to wipe the exterior of the unit. Do not use liquid cleaners, aerosols, or solvents, as these can damage the finish or internal components.
- Ventilation: Regularly check that the ventilation openings are clear of dust and debris. Ensure there is always adequate airflow around the amplifier to prevent overheating.
- Cable Connections: Periodically check all audio and power cable connections to ensure they are secure. Loose connections can lead to signal loss or intermittent performance.
- Storage: If storing the amplifier for an extended period, disconnect it from power, clean it, and store it in a dry, temperature-controlled environment, preferably in its original packaging.
9. Troubleshooting
If you encounter issues with your CLA-200 amplifier, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable disconnected; Power switch off; Incorrect voltage selection; Blown fuse | Check power cable connection; Ensure power switch is ON; Verify voltage selector setting; Consult qualified service personnel for fuse replacement. |
| No sound from speakers | Input cables disconnected/faulty; Speaker cables disconnected/faulty; Volume controls at minimum; Incorrect mode selection; Source device not sending signal | Check all input and speaker cable connections; Increase volume; Ensure correct mode (Stereo/Parallel/Bridge); Verify audio source is active and sending signal. |
| Distorted sound | Input signal too high; Amplifier overdriven (clipping); Faulty cables; Damaged speaker | Reduce input signal level from source; Lower amplifier volume; Check VU meters for clipping; Inspect cables for damage; Test with different speakers if possible. |
| One channel not working | Faulty input/speaker cable for that channel; Incorrect mode selection (e.g., Bridge mode selected for stereo); Faulty speaker | Swap input/speaker cables to isolate fault; Ensure Stereo or Parallel mode is selected for two-channel operation; Test with a different speaker. |
| Overheating | Blocked ventilation; Excessive load; Prolonged high-level operation | Ensure clear airflow around the unit; Reduce speaker load if possible; Allow amplifier to cool down. |
If the problem persists after attempting these solutions, please contact Avantone Pro customer support or your authorized dealer.
