5. Setup
5.1 Rack Mounting
The AX2000 is designed for standard 19-inch rack mounting. Secure the amplifier using appropriate rack screws (not included) to prevent movement and ensure proper ventilation within the rack. The unit occupies 2U of rack space.
5.2 Connecting Audio Sources
Use RCA cables to connect your audio source (e.g., mixer, CD player, audio interface) to the RCA input jacks on the rear panel. Ensure that Channel A input is connected to the left channel output of your source and Channel B input to the right channel output.
5.3 Connecting Speakers
Connect your passive speakers to the banana binding post outputs on the rear panel. Ensure correct polarity (+ to + and - to -) for each channel. The banana binding posts are compatible with banana plugs or bare wire connections.
5.4 Power Connection
After all audio connections are made, connect the provided AC power cord to the AC power inlet on the rear panel of the amplifier and then to a grounded 110V AC power outlet.
6. Operating Instructions
6.1 Powering On/Off
- Ensure all volume controls on the amplifier are set to their minimum position before powering on.
- Press the Power Switch on the front panel to turn the amplifier on. The power indicator will illuminate.
- To power off, press the Power Switch again.
6.2 Adjusting Volume Levels
Slowly turn up the Channel A and Channel B Volume Controls to achieve the desired output level. Adjust the volume gradually to avoid sudden loud sounds.
6.3 Monitoring Signal Levels
Observe the blue LED level meters on the front panel to monitor the audio signal strength. If the red CLIP indicator illuminates, it means the input signal is too strong, and clipping is occurring. Reduce the input level from your source or the amplifier's volume controls to prevent distortion and potential speaker damage.
7. Maintenance
7.1 Cleaning
Regularly clean the exterior of the amplifier with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure the unit is unplugged from the power source before cleaning.
7.2 Cooling System
Periodically check the cooling fan vents for dust accumulation. Use a soft brush or compressed air to clear any obstructions. Proper ventilation is crucial for the amplifier's longevity and stable operation.
