OPERATION: GAIN CONTROL SECURITY PLATE

Gain Control Security Plate

After final gain adjustments have been made, the gain controls can be covered with a security plate. This easy-to-use security plate makes it difficult for others to adjust the gain. This may be desirable in instances where the gain controls should not be tampered with. To install the security plate:

1.Use a 9/64” or 3.5mm hex key to loosen the screw. Do not remove; just loosen sev- eral turns.

3.Line up the tabs with the keyed portion of the ventilation slots, insert into the slot and then slide the panel fully right, locking it in the slot.

2.Orient the panel as shown and slide the right end of the plate under the screw.

4.Make sure the LED’s are visible, then tighten the screw with the hex key. Do not over tighten!

When properly installed, the security panel will still allow you to monitor all the channel status LED’s and power LED. The amplifier front panel will look like the illustration, right, after installing the security plate.
