The SAX100 amplifier may be operated in ambient
temperatures as high as 130°F. Forced air ventilation
may be required if the amplifier is installed in a con-
fined space or a rack with other heat producing com-
ponents.

The SAX100 has a single ended, one side grounded
input. The amplifier may be driven from any source ca-
pable of delivering 0.30 volt or more to a 50,000 ohm
load. The input connection is available at either of the
pin jack connections on the rear panel of the amplifier.

The output of the SAX100 can be connected for either
25 volt or 70 volt output. Either side of the output may
be grounded; or if no ground connection is made, the out-
put voltage will be balanced. If it is necessary that a
center point between the two lines be grounded, a 2,200
ohm ±5% 1 watt composition resistor may be connected
from each side of the output to ground.
The output connections are available on the nine pin
plug on the rear of the unit. The mating plug should be
wired as shown below in Fig. No. 1 for either 25 volt or
70 volt output. Assembly of the plug and pins is shown
in Fig. No. 2.

The amplifier is provided with two A.C. line power
transformer taps. If the amplifier is to be used on a line
voltage of less than 120 volts, the 120V tap should be
used. If the line voltage is greater than 12OV, the 13OV
tap should be used. These connections are accessible in
the upper left hand corner of the front chassis of the
amplifier. The amplifier is shipped from the factory wired
for 130 volt operation. The red-black wire is used for
the 130 volt connection, the yellow-black for the 120 volt
connection. To change the line voltage tap, disconnect
the wire going to the red-black lead and connect it to the
yellow-black, or vice versa.
