The DIN-25 umbilical cable should never be connected or removed with the power
supply chassis plugged into house power.
The preamplifier has five sets of stereo input connections, both single-ended and
balanced output connections and a full function remote control in addition to the normal
complement of front panel control functions.
The preamplifier's voltage and current rating are indicated by affixed tag on the rear of
the preamplifier’s separate power supply. It will indicate 240 volts, 220 volts, 120 volts,
or 100 volts. A 1.0 amp 3AG slow blow fuse is provided with 100-120 volt units, and a
0.50 amp slow blow fuse is provided with 220-240 volt units. The input frequency rating
of the power supply is 50 to 60 Hz. The preamplifier typically draws approximately 25
watts of power from the utility mains during operation.
Please verify that the indicated voltage requirement of this preamplifier’s power supply
is consistent with the utility voltage at your location.
We have provided a standard IEC AC power cord that fits into the IEC 320 line
receptacle at the rear of the power supply chassis. The preamplifier and power supply
is equipped for operation with an earth ground provided by the users AC outlet. Do not
defeat this safety ground. The chassis and circuit ground of the preamplifier is
connected to earth through a power thermistor, which gives a ground connection for
safety but helps avoid ground loop related noise issues.
Please connect the power
supply to the preamplifier chassis by the supplied umbilical before plugging the
power supply into the wall. Conversely please unplug the power supply from the
wall before disconnecting the umbilical cable.
