LOCATION
The P1000 power transformer can generate a substantial magnetic field, so caution should be exercised in the
placement of low level components such as a tape deck, mixer or mic preamp to avoid inducing noise in the low
level circuitry. The amplifiers can also produce considerable heat in normal operation so the primary consideration
when determining a location for the amplifiers is to allow for adequate ventilation. The large heatsinks provide
unrestricted airflow, but care must be taken to keep the slots in the bottom panel and top cover clear. If the amplifier
is mounted in an equipment rack, make sure adjacent equipment does not impede cool air flow.
Rack systems should have two fans 4" to 5" in from the front of the amplifier blowing upward.
Inadequate ventilation can shorten component life, especially when other equipment raises the ambient air
temperature, so circulating fans should be considered in tight quarters.

AC LINE
The P1000 is capable of operation from either a 115 VAC/60Hz or a 230 VAC/50-60Hz power line. The power line
selector switch is located on the rear panel. Check that the switch is set in the correct position before putting the
amplifier into service.
Connection is made by a 16 gauge, IEC Type 320, grounded line cord. For safety considerations only a properly
grounded (earthed) receptacle should be used. If a grounded circuit is not available, do not break off the ground
pin; use the proper adapter plug for a two wire receptacle.
IMPORTANT: The power line fuse is mounted on the rear panel of the amplifier. If this fuse blows, replace
it only with a fuse of the same type and rating. The correct replacement fuse value is printed in the
parts list.

UNBALANCED INPUT
The unbalanced inputs use conventional RCA phone jacks. Set the BALANCED/UNBALANCED switch to the
UNBALANCED position to use these jacks.
