GAIN CONTROLS

Turn the gain controls clockwise to increase gain and counterclockwise to decrease gain. At the maximum setting, the voltage gain of the amplifier is +35 dB, and a 1.26V input signal produces 70V at the output.

The Gain controls are marked in dB of attenuation. There are 21 detents for repeatable adjustments. The upper 14 steps are about 1 dB each, and settings should normally be made within this range. The range below -14 dB should not be used for normal program levels, as the input headroom could be exceeded, but can be used for testing at reduced levels. At the minimum setting, the signal is completely cut off.

The Gain controls are recessed and can be adjusted with a small screwdriver or flat tool. If desired, the Gain Control Security Cover can be installed to prevent changes to the installer's settings.

GAIN CONTROL SECURITY PLATE

The cover blocks access to the Gain settings. The LED indicators are still visible to mon- itor the system's operation.

1.Use a 9/64" or 3.5 mm hex driver to loosen the screw several turns. Do not remove it completely.

2.Slide the right end of the cover under the loosened screw.

3.Insert the left end tabs into the last row of ventilation slots, and slide the panel fully to the right. It should lock into the slots.

4.Confirm that the LED's are visible through the cover. Tighten the hex screw carefully.
