LINE VOLTAGE
The 945 Preamp/Tuner is supplied in either a 17” Black Version, or a 19” Silver Version. The 19” model
has rackmounting holes provided for installation in equipment racks. The holes are on standard EIA
spacings, though the faceplate height is not standard EIA size.
The 945 produces very little heat during operation, and therefore requires no special considerations for
ventilation. The preamp/tuner should be located at least several inches away from components that
contain large power transformers (such as power amplifiers), due to the possibility of audible hum or buzz
from magnetic radiation.
The 945 Preamp/Tuner is available in either 120 VAC or 240 VAC, 50/60 Hz versions . Make sure that
the unit is configured for your local AC line voltage before attempted use. The configuration is labelled
directly above the power cord entry point.

OUTLETS
Units wired for 240 VAC are supplied without AC power cords. Local agents will supply cords with male
connectors appropriate to the local standard.
Units wired for 120 VAC are supplied with a detachable AC power cord. The female connector plugs
into the receptacle provided on the rear panel. This power cord is a standard IEC Type 320, 3-wire, 16
gauge assembly. Should replacement ever be necessary, be sure to replace it with an identical cord.
Never remove the grounding pin from the male end of the cord. In applications where a grounded wall
outlet is not available, a ground adaptor should be employed, with the ground tab or wire of the adaptor
connected to a suitable earth ground.
Units wired for 720 VAC have a total of four outlets for connection of associated components. The
polarized Unswitched Outlet is powered at all times, which should generally be used for a turntable or
tape deck. The remaining three Switched Outlets (one grounded, two polarized) are powered when the
Power Switch is engaged, as indicated by the switch’s green light. The grounded outlet is provided for
equipment requiring a grounded connection.
Units wired for 240 VAC have a total of three reverse-IEC outlets for connection of associated com-
ponents. The Unswitched Outlet is powered at all times, which should generally be used for a turntable
or tape deck. The remaining two Switched Outlets are powered when the Power Switch is engaged, as
indicated by the switch’s green light.
for all models, the maximum power available from the Unswitched Outlet is 200 watts. The maximum
total power available from the Switched Outlets is 800 watts. This total power may be drawn from a single
outlet, or a combination of outlets. Since some power amplifiers consume more than 800 watts at
maximum output, check the power amplifier’s rating before connecting to these convenience outlets.
