the front panel is switched to the OFF (O) position.
Make sure the power cord is inserted and seated
fully into the IEC connector by moving it slightly
back and forth and up and down while pushing
in. The power cord is relatively stiff and should be
routed so that there is no excessive force pulling to
the sides or up or down that would stress the pins
or internal connections. Tighten the cord strain
relief screw to lock the power cord in place.

Figure 3.6 – Sample of Configurations Setting Label
Review the factory-set supply voltage and ampli-
fier configuration detailed on the label placed on
the side of the amplifier (see Figure 3.6). This
configuration can be changed by the user. See

Start-up Procedure
3.5.1
Voltage-Mode Operation
Perform the following steps to startup and operate
your amplifier in Controlled-Voltage.
1. Turn down the level of your signal source.
2. Turn down the gain control of the amplifier.
3. Depress the POWER switch to turn the
amplifier ON.
4. Wait for the yellow READY and green RUN
LEDs to illuminate.
5. Adjust the level of your input signal source
to achieve the desired output level.
6. Turn up the Gain control on the amplifier
until the desired voltage or power level is
achieved.
7. Adjust the input signal level to achieve the
desired output level.
3.5.1
Current-Mode Operation
Before configuring your amplifier for Current mode
operation, it is important to verify the amplifier is
operating correctly in Voltage mode. Perform the
steps provided in the "Voltage-Mode Opera-
tion" Start-up Procedure to test the amplifier in
Controlled-Voltage mode. Use care if your load is
very-low impedance since high currents can be
caused by low input levels. Then refer to the "Ap-
plications" section of this manual for instructions
on Controlled-Current configuration and operation.
