Note: To get the best out of the remote control functions, please use ONLY the supplied remote control with your QUAD 33.

Connections

Analogue Outputs

Balanced Output
Balanced connections provide greater dynamic headroom and lower noise. If your amplifier has balanced inputs (such as the matching QUAD 303 power amplifier), it is recommended that you use the balanced connections, whenever possible.

Unbalanced Output (AUX)
The AUX direct output is used for connecting to a unit with Line (RCA) inputs that requires no preprocessing or volume control of the signal, for example an integrated amplifier, audio processor, AV controller or an audio recording device.

Pre-Out
If you cannot use the balanced outputs, connect high quality stereo screened RCA cables from the Pre outputs of the QUAD 33 to Line (RCA) inputs of your power amplifier (such as the the QUAD 303).

Headphone Output
A stereo 6.3mm (1/4") jack is provided on the front panel for connecting headphones. When headphones are connected the speaker outputs will be deactivated.

Analogue Inputs

Balanced Input
Balanced connections provide greater dynamic range and lower noise. If your source has balanced outputs, please connect them to the QUAD 33 balanced inputs. You will need one XLR balanced cable per channel.

Unbalanced Input(AUX)
Connect your analogue sources to one of the three line-level inputs AUX1, AUX2 or AUX3.

Phono Input(MM/MC)
Connect your turntable to the phono input. Connect the earth lead from your turntable (if available) to the ground terminal.
The QUAD 33 phono preamplifier input is compatible with MM and MC cartridge types. You can select the MM of MC functionality by cycle pressing the 'phono' button on the front panel or remote control handset.
