4.3.4 Compensation Setting (applies to
Controlled Current operation only)
When the amplifier is used in Controlled Current
(CC) mode, the current control loop is tuned with
one of two available RC networks: CC1 (R63 and
C16) or CC2 (R82 and C25). Place Jumper J5 in
the UP position to select the CC1 network (factory
default). Place Jumper J5 in the DOWN position
to select the CC2 network. See Figure 4.4.

4.3.5 Ready/Run Mode or Standby Mode
Power-up
The amplifier will bypass Standby Mode and cycle
directly to Ready/Run Mode on power-up when
Jumper J11 is in the Left position (factory default).
To set the amplifier to power-up to Standby Mode,
place Jumper J11 in the Right position. See Fig-
ure 4.5.

4.3.6 Standby Mode on Overload
When this option is enabled, the amplifier will
move into Standby Mode when it senses an activa-
tion of the IOC (Input/Output Comparator) Distor-
tion Alert circuit. The IOC Distortion Alert circuit
continuously compares the input waveform to the
output waveform. When a distortion of more than
0.5% occurs, the IOC circuit will activate. The am-
plifier will remain in Standby Mode until the Reset
switch on the front panel is pushed or a Reset
signal is received on the Interlock – I/O Connector.
Figure 4.6 – Standby Mode on Overload Setting
Once reset, the amplifier will return to Ready/Run
(operational) Mode. To enable Standby Mode on
Overload, place the jumper across the two pins
labeled J13. See Figure 4.6.
