5. Setup
Follow these steps to set up your Technical Pro AX1200 amplifier:
- Placement:
- Place the amplifier in a well-ventilated area. Avoid direct sunlight or heat sources.
- The AX1200 is designed for 2U rack mounting. Ensure proper rack ventilation if installed in an equipment rack.
- Audio Input Connection:
- Using RCA cables, connect your audio source (e.g., DJ mixer, audio interface) to the AUDIO INPUTS (RCA) on the rear panel. Match Channel A to your left audio signal and Channel B to your right audio signal.
- Speaker Output Connection:
- Connect your passive speakers to the CH A / CH B OUTPUTS (Banana Binding Post) on the rear panel.
- Ensure correct polarity: connect the positive (+) terminal of the amplifier to the positive (+) terminal of the speaker, and the negative (-) terminal of the amplifier to the negative (-) terminal of the speaker. Incorrect polarity can result in poor sound quality.
- Verify that your speakers' impedance is compatible with the amplifier's output capabilities (e.g., 2 ohms, 4 ohms, 8 ohms).
- Power Connection:
- Ensure the amplifier's POWER switch is in the OFF position.
- Connect the supplied AC power cable to the AC Power Inlet on the rear panel of the amplifier.
- Plug the other end of the power cable into a standard 110V-60Hz AC wall outlet.
6. Operating Instructions
Once the amplifier is properly set up, follow these steps for operation:
- Power On:
- Before powering on, ensure the CH-A / CH-B Level Controls on the front panel are set to their minimum (MIN) position.
- Flip the POWER Switch to the ON position. The POWER indicators and iridescent blue LED meters should illuminate.
- Adjusting Levels:
- Start playing audio from your source at a moderate level.
- Slowly increase the CH-A / CH-B Level Controls on the amplifier until the desired volume is reached.
- Monitor the CLIP Indicators. If they light up frequently or stay lit, reduce the input level from your source or the amplifier's level controls to prevent distortion and potential speaker damage.
- Power Off:
- Before powering off, it is recommended to reduce the CH-A / CH-B Level Controls to their minimum position.
- Flip the POWER Switch to the OFF position.
7. Maintenance
Proper maintenance ensures the longevity and optimal performance of your amplifier.
- Cleaning:
- Always unplug the amplifier from the power outlet before cleaning.
- Use a soft, dry cloth to wipe down the exterior surfaces. Do not use liquid cleaners, aerosols, or abrasive chemicals.
- Ventilation:
- Regularly check that the ventilation openings are clear of dust and debris. Blocked vents can lead to overheating.
- Ensure there is sufficient space around the amplifier for proper airflow, especially if rack-mounted.
- Cable Connections: Periodically check all cable connections (power, input, output) to ensure they are secure and free from damage.
