Installation

Unpack and inspect contents. Place on stable, level surface with adequate ventilation.

1. Position amplifier: Ensure minimum 10cm clearance on all sides for proper ventilation.
2. Connect speakers: Use high-quality speaker cables to appropriate terminals.
3. Connect source devices: Use RCA or XLR cables for audio sources.
4. Connect phono: For turntable with magnetic cartridge.
5. Plug into AC power outlet.

WARNING! Amplifier is heavy; lift with care using two people. Ensure proper ventilation to prevent overheating.

First-Time Setup

Power on amplifier; allow warm-up time for optimal performance.

1. Input selection: Use INPUT SELECTOR to choose appropriate source.
2. Volume control: Start with volume at minimum, gradually increase.
3. Balance adjustment: Use BALANCE control if needed.
4. Speaker connections: Ensure correct polarity (red to red, black to black).
5. Remote setup: Install batteries in RC-11S2 remote.

CAUTION! Do not connect or disconnect cables while amplifier is powered on. Allow 30 minutes warm-up for best sound quality.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No sound	Input selection/volume	Check input selection; increase volume; ensure speakers connected.
Distorted sound	Overload/connections	Reduce volume; check speaker connections; verify source quality.
One channel silent	Balance/cable	Adjust balance control; check cable connections; swap channels to test.
Hum or noise	Grounding/cables	Check grounding; use quality cables; separate from power cables.
Protection mode active	Overload/short circuit	Turn off, check speaker wires for shorts, allow cooling, restart.

Reset: Power cycle amplifier if issues persist.
