QUAD 33 Pre Amplifier

The external design is specifically intended to continue the QUAD

tradition of practical simplicity. Yet, it would be foolish to ignore

the implementation of modern-day capabilities, such as an informative

backlit display, delicate LED illumination and remote control

functionality. And just like the original, the overall appearance is

unmistakably QUAD, albeit now with a premium machined and anodised front

panel and all-metal chassis.

The new QUAD 33 is supported by digital microprocessor control but is otherwise faithful to a classic analogue design.

The 33 feeds the loudspeakers via the power amplifier using dedicated

stereo pre-outputs, with an RCA line-level and balanced XLR pre-out

option. For additional versatility and functionality, there’s also an

AUX output.
