Installation

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

1. Connect speakers: Use high-quality speaker cables to gold-plated binding posts.
2. Connect source components: Use RCA or XLR cables for balanced/unbalanced connections.
3. Connect turntable: Use phono input for MM/MC cartridges with proper grounding.
4. Plug into AC power outlet (120V, 60Hz).

WARNING! Amplifier is heavy; lift with care using proper technique. Ensure adequate ventilation space around unit.

First-Time Setup

Power on amplifier; allow 30 minutes warm-up for optimal performance.

1. Input selection: Rotate INPUT selector to desired source (CD, TUNER, PHONO, etc.).
2. Volume adjustment: Start with volume at minimum, gradually increase to listening level.
3. Phono setup: Select MM/MC setting based on cartridge type; adjust loading if needed.
4. Tone controls: Set to preference or use DIRECT mode for pure signal path.

CAUTION! Always turn volume to minimum before powering on/off to protect speakers.
