SLS Audio QG-500AVR 5.1-Channel Surround Sound Home Theater AV Receiver

Up for sale is a used SLS Audio 5.1-Channel Surround Sound Home Theater AV Receiver (Model: QG-500AVR / OG-500AVR), finished in sleek anodized black.

This receiver was originally manufactured as the central powerhouse for SLS Audio’s highly acclaimed Q-Line Gold and Silver home theater systems—a specialized setup famously co-engineered, refined, and endorsed by legendary music producer Quincy Jones. Built for SLS by the seasoned audio experts at Sherwood, this receiver is designed to handle high-fidelity dynamics with an output of 100 Watts per channel. It comes fully loaded with classic processing formats including Dolby Digital EX, Dolby Pro Logic IIx, and DTS Digital Surround, making it an absolute treat for a dedicated 5.1 living room cinema layout or a high-performance stereo audio listening setup.

Condition & Testing Notes:

• Performance Audio: In Good Working Order. This receiver has been carefully bench-tested in our retail shop across all standard analog (RCA) inputs, auxiliary paths, and main discrete speaker output terminal channels (Front, Center, and Surround). Audio signals pass clearly, cleanly, and balanced with plenty of dynamic push.
• Testing Limitations: Please note that while the core audio amplification section operates beautifully as expected, this unit has not been fully tested across all ancillary sub-systems, such as its analog composite/component video routing matrix or the onboard AM/FM radio tuner tracking. It is priced accordingly as a reliable, heavy-hitting multi-channel audio amplifier node.
• Cosmetics: Shows minor, honest cosmetic scuffs and faint hairline scratches on the top metal cabinet panel and around the rear jacks consistent with normal shelf integration and equipment stacked placement over time. The front display lens is clear, and the interface buttons are crisp (please see all detailed photos).
• Note: This listing is for the standalone receiver with its factory-attached power cable only. A remote control, AM/FM antennas, or original packaging are not included.

Shipping & Store Policies:

• Shipping: Home theater AV receivers house heavy, high-current power transformers.
