Installation

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

1. Connect speakers: Use heavy gauge speaker wire to A/B speaker terminals.
2. Connect source components: Use appropriate cables for phono, CD player, tuner, etc.
3. Connect power cord: Plug into grounded AC outlet.
4. Ensure proper ventilation: Allow at least 4 inches clearance on all sides.

WARNING! Ensure proper grounding. Do not block ventilation openings.

Operation Guide

Power on amplifier; allow 30 seconds for stabilization.

1. Select input source: Turn INPUT SELECTOR to desired position (Phono, CD, etc.).
2. Adjust volume: Start with volume at minimum, gradually increase to desired level.
3. Select speakers: Use SPEAKER A/B switches to activate connected speakers.
4. Use tone controls: Adjust bass and treble to suit listening preferences.

CAUTION! Avoid operating at maximum volume for extended periods.

Controls and Functions

Front Panel: POWER switch, INPUT SELECTOR, VOLUME, BALANCE, TONE CONTROLS, LOUDNESS, SPEAKER SELECTOR.

Rear Panel: AC power inlet, PHONO inputs, LINE inputs, TAPE inputs/outputs, SPEAKER terminals.

Input Selection: Phono, CD, Tuner, Aux, Tape 1, Tape 2. Tone Controls: Bass and treble with center detent. Loudness: Compensates for Fletcher-Munson curves at low volumes. Speaker Selection: Independent A/B switching for multiple speaker systems.

Connecting Components

Phono: Use shielded cables for turntable connection. CD Player: Connect to CD input. Tape Deck: Use REC OUT/PLAY IN for recording.

1. Turn off power before making connections.
2. Use high-quality interconnects for best performance.
3. Match cable colors (red-right, white-left).
4. Ensure secure connections to prevent hum and noise.

Tip: Keep signal cables away from power cords to minimize interference.

Phono Section

Supports both moving magnet (MM) and moving coil (MC) cartridges.

1. MM Cartridges: Standard 47k ohm loading, 100pF capacitance.
2. MC Cartridges: Use external step-up transformer or head amplifier.
3. Grounding: Connect turntable ground wire to PHONO GND terminal.
4. Adjustments: Use INPUT SENSITIVITY if available for optimal matching.

WARNING! Do not connect line-level sources to phono input.

Tone Controls

Bass and treble controls with defeat function for pure signal path.

Bass Control: ±10dB at 100Hz. Treble Control: ±10dB at 10kHz. Loudness: Engages bass boost at low volume settings. Tone Defeat: Bypasses tone control circuitry for direct signal path.

Maintenance

Unplug before cleaning. Use soft, dry cloth for exterior. Clean controls with contact cleaner if necessary.

CAUTION! Do not use solvents or abrasive cleaners. Keep away from moisture.

Technical Information

Direct coupling design eliminates output capacitor for improved bass response. Dual power supply provides stable operation. Protection circuitry prevents damage from shorts and overloads. Manufactured to meet international safety standards.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No sound	Power/speaker selection	Check power connection; verify speaker selection; ensure volume up.
Hum or noise	Grounding/cables	Check ground connections; ensure cables properly shielded.
Distorted sound	Overload/connections	Reduce volume; check speaker connections; verify source level.
One channel dead	Balance/connections	Check balance control; verify cable connections; test speakers.
Protection circuit active	Short circuit/overload	Check speaker wires for shorts; allow cool-down period.

Reset: Turn off power, wait 30 seconds, restart.
