M Series Power Amplifiers

4Advanced Features and Options

4.3Optional 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.

4.5Optional 0.775-V Input Sensi- 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.
