Quad 66 Pre


The Quad 66 is a high quality preamplifier system with full remote control operation.

It comprises two units; a mains operated preamp to which the various sound sources are connected and a separate battery operated control panel incorporating all the main function controls for operating the preamp and Quad CD player, or any other remote control CD player using the same remote control language.

If the battery fails the control panel can be directly powered from the preamp. A display on the main unit shows all functions selected.

The unit will accept inputs from seven sources; Disc, CD Radio, AV, Aux 1, Aux 2 and Tape (with off tape monitoring).

A second tape recorder may be connected to the Aux 2 input and both the AV and Aux 1 inputs have anti hum-loop circuitry.

The control panel has rotary volume and balance adjustment plus press buttons for Disc, CD play, Radio, AV, Aux 1 and 2, Tape, Tilt (2), Bass Step (2), Filter (2), Cancel, Standby, Search (2), Track, Pause, Stop and Store.

The standby facility enables the 66, and any other equipment connected to the AC auxiliary outlet, to be switched on and off via the remote control panel.

Just replaced my upgraded Quad33 with a 66 preamp. Even though the 33 was good, this is another level of performance - especially in the mid/bass range, Can't wait to upgrade this one!

re: 66 Pre

I have a Quad 66 preamp with 306 amp. Very loyal to it.

Have just acquired a Naim Nova and Core which are networked; but I want to play from the Core server through the Quad in another room. (The Quad 66 CD player having just broken down, uneconomically).

Any ideas please on how I might connect it? Could I use the CD jacks from a usb?

Just re-activated my 25yo units p/ 5 years in storage. Still work wonderfully. Thanks for manuals. Z, Biloxi-MS and Detroit-MI

Thanks very much for providing this. I bought my kit second hand and this is the first time I've had the opportunity to read the manual. Cheers!

Thanks for this. My manual got mislaid during a home-move. Have just bought my second Quad 66 (bought June 2010) after 25 years of happy service from the first!
