OWNER’S MANUAL MODEL 312 STEREO AMPLIFIER

Locate the amplifier as close as possible to its final installation point. Allow access to the rear panel for making connections.

The Model 312 Stereo Power Amplifier is extremely efficient and convection cooled, eliminating the need for fans or forced-air cooling. Multiple chassis can be stacked vertically, facilitating an upward flow of warm air currents throughout the vertical heatsink areas. This upward flow must not be blocked or recirculated around the chassis if proper cooling is to be maintained.

Typical installations allow the amplifier to be rigidly coupled to a support structure or floor via optional spiked coupling supports that are available separately from JRDG. In carpeted installations, these supports provide excellent anchoring from the amplifier chassis to the rigid floor or sub-floor below. If there is concern about damage to the structure or floor’s finish, a coin can be placed beneath each spiked coupling support. In installations where the resonant properties of the supporting structure are poor or unknown, the amplifier chassis can be loosely coupled to the supporting structure via the supplied compliant isolation interface pads. This will help to attenuate the transfer of vibration or resonant energy from the support structure to the amplifier chassis.

RISK OF ELECTRICAL SHOCK!

WARNING: Do not attempt to access the interior of the MODEL 312 STEREO AMPLIFIER by removing the top or bottom cover. Doing so will void your warranty and could expose you to dangerous, potentially lethal electrical voltages.
