M Series Power Amplifiers
4 Advanced Features
and Options
4.3 Optional Barrier Block Outputs
If you prefer, the 5-way binding post outputs on
your M-Series amplifier can be replaced with
model CEAS1 barrier block outputs (see Figure
4.3). You can order your M-Series amplifier
with barrier block outputs factory-installed on
new amplifiers or they can be added to existing
M-Series amplifiers by an authorized Crown
Service Center. Please contact Crown Technical
Support or your local Crown Service Center for
more information on this option.

4.4 Tamper-Resistant Hole Plugs

Your M-Series amplifier comes with a set of
tamper-resistant hole plugs, which allow you to
"protect" the level controls against unautho-
rized adjustment. To use, simply pull off the
control knobs from the front of the amp, and

slip the hole plugs into place (see Figure 4.4).
The plugs should slide easily into position,
without forcing. Once in place, the plugs will
help to avoid most accidental or intentional
tampering (some situations may require addi-
tional security measures).
To remove the hole plugs, simply pry the plug
away from the amplifier case using a small, flat-
blade screwdriver. To help to ensure adequate
security, the plugs have been designed to be
more difficult to remove than to place into posi-
tion. If necessary, additional hole plugs can be
purchased separately from Crown's Parts
Department (Part # 103234-1).
Store your knobs in a safe location should you
need to make level adjustments in the future.

tivity Setting
The M-Series amplifier also provides an
optional 0.775-V input sensitivity setting. If you
determine your application requires this sensi-
tivity setting, please contact Crown Technical
Support for more information.
