LOCATION
The P1500 and P3000 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 P1500U and P3000U operate from a 120 volt, 60Hz AC power line. The P1500CE and P3000CE operate from
a 230 volt, 50-60Hz AC power line. 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. Mounted on the rear panel
is the line fuse which interrupts the power to the amplifier. If this fuse blows replace it only with the same type
and rating fuse. The correct replacement fuse value is printed on the rear panel of the amplifier. If the new fuse
blows, this is an indication of a fault with the amplifier. Servicing should be performed only by a qualified
technician.
