3. INSTALLATION 3.1 AC Mains Supply. The equipment is fitted with a 3-pin IEC connector which is approved internationally. A mating socket with power cord and mains plug is supplied. Before connecting the unit to the supply, check that the equipment is set for the correct mains voltage. The unit is set for 110-120V 60Hz or 220-240V 50Hz operation internally, and should only be changed by an authorized service centre. -

Increasing the input gain pushes more signal level into the valve, thus generating more harmonic distortion and creating that special “valve sound”. At the same time the output level can be turned down to preserve the same level at the outputs, so a choice of sounds is available. -
Page 10: Output Gain
5.6 Output Gain. This controls the level at the equipment outputs, and is variable between -∞ and +15dB. This control acts like an output fader effectively, and is very useful when recording direct to tape or hard disc through the equipment. You may find that some digital recorders require a good deal of input level in order to register a 0dB reading on their meters. -
