Changing Output Level Chart

To reduce the output connect

additional resistors in parallel

with R119|122 as follows:

470{llor 9 dB attenuation (180 mV)

180Q for 15 dB attenuation ( 90 mV )

100Cr for 20 dB attenuation ( 50 mV)

To increase the output

change resistors as

follows:

All input connections are clearly marked on the back of the control unit. Phono

sockets are used for all inputs and an earth/ground terminal is provided for the

Disc input if separate grounding is required.

The signal cable from the turntable should be plugged into the DISC L and R

sockets. This will normally incorporate a separate earth/ground lead which must

be connected to the earth/ground terminal to avoid hum problems.

The 34 is supplied fitted with a disc input module suitable for most high quality

moving magnet cartridges. Other modules are available with different input

impedances and sensitivities for moving magnet and moving coil cartridges.

Contact your dealer or Quad direct for further details.

The signal cable from the CD player should be connected to the GD L and R

sockets. The normal input sensitivity of 300 mV is suitable for all CD players but

this can be altered by replacing the plug-in 'flags' into resistor sockets R1 35/1 36.

Flags for input sensitivities of 100 mV and 500 mV can be obtained either from

your dealer or Quad direct. This input is intended primarily for compact disc

players but can be used as an auxiliary input for a Nicam/Satellite receiver or

similar source.

For a Quad FM tuner or other tuners of a similar output level. The tuner signal

cable should be connected to the RAD L and R sockets.

The signal playback cable should be connected to the REP L and R sockets and

the record cable to the REG L and R sockets. The record and replay levels of

300 mV have been chosen to suit most recorders currently available and can

be altered by replacing the plug-in'flags'into

R135/136 (record)

andR137/138(replay).

To switch on press the on/off bufton on the front of the control unit. This has

a sequential action so pressing it again will switch the unit off. Any equipment

connected to the auxiliary AC outlet socket will also be switched at the same

time. When switched on the 34 automatically selects RADIO. Other inputs and

functions can easily be selected as required.

Normally any equipment connected to the auxiliary AC power out socket would

be left switched on and the equipment turned on and off using the on/off button

on the 34 control unit.

Select the required input source by pressing the appropriate selector button.

The green LED next to the chosen input will light to show which source is

selected.
