The 915 Preamplifier 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.

The 915 produces very little heat during operation, and therefore requires no special consider-
ations for ventilation. The preamplifier 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 915 Preamplifier is configurable for either 100  - 120 volt, or 200  - 240 volt operation. This
is accomplished by changing internal jumpers on the printed circuit board. The procedure is
detailed in the section “CHANGING LINE VOLTAGE RATING”. 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 connector.

UP/MUTING

SYSTEM

Units wired for200-240

VACare  supplied without power cords. Local agents will supply cords with

male connectors appropriate to the local standard.

Units wired

for 100-120 

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, 18 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.

For units wired 

for 200-240 

VAC, 

the front panel Power Switch controls the power to the

Preamplifier’s circuitry. If desired, this switch may be left “on” at all times to allow circuits to be

thermally stabilized for maximum fidelity as soon as the system is used.
