4.1.5 Fault Status Indicators
Four Fault Status indicators are located on the
amplifier front panel (see Figure 4.4). These LEDs
monitor the internal conditions of the amplifier
and will illuminate when a fault condition occurs.
Depending on the fault condition and the configu-
ration of the unit, the amplifier may be placed in
Standby mode when a fault condition occurs. Re-
fer to the chart in Figure 4.6 to determine the fault
condition being indicated and the action required
to clear the fault condition.
NOTE: See the "Applications" section for fault
status indicator interpretation when operating a
multi-amp system.
Back-Panel Controls

and Connectors
This section provides an overview of Back-Panel
controls and connectors found on the 7224/7226.
Please refer to Figure 4.7 for visual locations.
AC Supply – Standard 20 amp 3-pin IEC-type
male connector.
Output Terminal Strip – Connect output lines
97-8004167 07-14-17

Information subject to change
from the load to this 3-position terminal strip with
#8 screws. It accepts up to #10 AWG wire.
BNC Input Connector – This input option pro-
vides a standard unbalanced input.
Input Selector Switch – When in the LEFT
position, the unbalanced BNC input connector is
enabled. When in the RIGHT position, both unbal-
anced BNC and balanced Phoenix® input con-
nectors are enabled. The Input Select switch also
functions as a Ground Lift switch for the Unbal-
anced BNC input connector. If circulating currents/
ground loops/60-Hz Hum occur when using the
unbalanced input, move the Input Select switch to
the right to lift the ground on the connector.
Terminal Block Input Connector – This input op-
tion provides a balanced input. It can also be used
as an unbalanced input.
Interlock Connector – This 25-pin, D-sub connec-
tor is used for interlocking and combining functions
in a system of multiple amplifiers. It can also be
used for remote control and monitoring applica-
tions (see the "Applications" section for more
information).
