🌟 Standout Highlight – Full Immersion with 1970s Quad Sound

The Pioneer QX-747 wasn’t just a receiver — it was a revolution in home listening.

In an era dominated by stereo, this unit offered discrete 4-channel playback, giving listeners a true surround-sound experience decades before home theaters existed.

Its compatibility with CD-4 and SQ quad formats, combined with the ability to fall back to high-power stereo mode, makes it one of the most versatile and musically engaging receivers of its time.

Few vintage units offer such a unique blend of analog charm, power, and spatial depth.

🌟 A Receiver That Dared to Go Beyond Stereo

At a time when most homes were just discovering stereo, the Pioneer QX-747 pushed boundaries — delivering true quadraphonic sound that surrounded the listener with depth and motion.

This wasn’t just about more channels — it was about reimagining the listening space. With dedicated quad decoding and the power to drive four speakers with clarity and balance, the QX-747 transformed living rooms into immersive sound stages, long before surround sound became mainstream.

Its elegant layout, glowing meters, and tactile feel reflect an era where audio was both art and engineering — and where Pioneer led the way with vision and style.

Condition:

This receiver is in “Excellent” condition, displaying minor signs of use with a bright, clear dial. All knobs, feet, and the attached AM antenna and AC cord are present and intact. Although the manual is missing, it can be found online or we can provide a PDF upon request. Please inspect all photos thoroughly for the actual condition.

Service:

Upon inspection, the unit had scratchy controls, a dim dial, and some distortion in one channel. Therefore, it underwent servicing by our technician. Pioneer used certain transistors in this model that are known to fail after 40 years, so all of these were replaced. This upgrade resolved the distortion issue. Additionally, several questionable capacitors were replaced. 

Testing:

After servicing, the receiver was tested on our bench and performed excellently, delivering a powerful, warm, distortion-free signal characteristic of analog receivers. All inputs, outputs, and features were confirmed operational, and the tuner spins smoothly. Additional testing was conducted, and we can provide specific feature information upon request. This is a remarkable find for the vintage audiophile.
