High frequencies are clear and energetic, while the tone controls, filters, loudness function, and audio muting provide extensive adjustment for different speakers, recordings, and listening rooms.

Important Vintage Audio Note

This is a large, high-powered vintage stereo receiver and must be used with adequate ventilation.

Do not cover the upper ventilation grille or install the receiver inside a tightly enclosed cabinet.

Confirm that the rear voltage selector matches the local AC supply before connecting the receiver to power.

Switch the receiver off before connecting or disconnecting speakers, turntables, tape decks, preamplifiers, power amplifiers, antennas, or other components.

Confirm the speaker impedance and wiring configuration before operation, particularly when using more than one speaker pair.

Because the receiver weighs approximately 52 lbs, two-person handling is recommended when unpacking, moving, or positioning it.

The appearance of the illuminated dial and meters may vary depending on room lighting, camera exposure, and display settings.
