With the LIFT switch you can isolate input from turntable/pickup arm ground as well as the

ground of the box containing this circuit. On certain cases this can help in the reduction of

noise and "hum". If you experience any 'hum' induced by the proximity to other

electronics, move the SUT n°3 to a different location, further away from possible causes of

noise, and try to change its orientation rotating it clockwise/anticlockwise until any noise is

eliminated or reduced to an acceptable level.

The figure 4 represents the front panel of the SUT n°3. The SUT N°3 is switchable for gain

(1:12, 22 dB gain or 1:24, 28 dB gain) and impedance (LOAD). There are two knobs, one for

the gain (the lower one) and one for the load (the one at the top). Once all connections

have been made, adjust the gain and the impedance switches on the front panel of the SUT

N°3 to the appropriate setting for your cartridge. Mute your amplifiers or turn them down

while adjusting the LOAD and GAIN to protect your speakers as pulses may be generated.

The table below gives an indication of the most suitable gain setting for your cartridge:

please note that it will depend upon the characteristics of the following phonostage,

amplifiers and speakers sensitivity.

0,1 – 0,2 mV 0,2 – 0,3 mV 0,3 – 0,4 mV 0,4 – 0,5 mV

12x – 22dB

24x – 28dB
