3. Setup and Installation
3.1 Unpacking
Carefully remove the amplifier from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. Report any damage to your dealer immediately.
3.2 Placement
Place the amplifier on a stable, flat surface. Ensure there is sufficient space around the unit for proper airflow to prevent overheating. The unit is designed for surface mounting.
3.3 Connections
Before making any connections, ensure the amplifier is powered off and unplugged from the electrical outlet.
- Input Sources: Connect your audio sources (e.g., mixing board, microphone) to the appropriate input jacks on the rear panel. Refer to the rear panel diagram (not provided in current data, but implied for a manual) for specific input types and locations.
- Speaker Outputs: Connect your speakers to the amplifier's output terminals. Ensure correct polarity (+ to + and - to -) for all speaker connections. This amplifier is suitable for 70V transformer-isolated balanced speakers.
- Power Connection: Once all audio connections are secure, plug the amplifier's power cord into a grounded 120V AC, 60Hz electrical outlet.
4. Operating Instructions
4.1 Powering On/Off
Locate the red power switch on the front panel. Press the switch to the 'ON' position to power on the amplifier. The switch will illuminate when the unit is powered on. Press it again to power off.
4.2 Adjusting Input Levels
The front panel features individual input level controls. Rotate these knobs clockwise to increase the volume for the corresponding input, and counter-clockwise to decrease it. Adjust these controls to achieve a balanced sound level from all connected sources.
4.3 Tone Controls
The amplifier includes BASS and TREBLE tone controls. Adjust these to fine-tune the audio output to your preference or room acoustics.
- BASS: Controls the low-frequency response. Turn clockwise for more bass, counter-clockwise for less.
- TREBLE: Controls the high-frequency response. Turn clockwise for more treble, counter-clockwise for less.
4.4 Master Volume
The master volume control adjusts the overall output level of the amplifier. Start with the master volume at a low setting and gradually increase it to the desired listening level. Avoid setting the volume too high, which can cause distortion or damage to speakers.
5. Maintenance
5.1 Cleaning
To clean the amplifier, first unplug it from the power outlet. Use a soft, dry cloth to wipe down the exterior surfaces. Do not use liquid cleaners or aerosol sprays, as these can damage the finish or internal components.
5.2 Ventilation
Regularly check that the ventilation slots on the top and sides of the unit are free from dust and obstructions. Blocked vents can lead to overheating and reduced performance.
5.3 Storage
If storing the amplifier for an extended period, ensure it is powered off, unplugged, and stored in a cool, dry place away from direct sunlight and extreme temperatures.
