The Model T6400 2-Card Power Amplifier Mainframe is designed to house, supply power to and cool up to two Titan series power amplifier cards. The mainframe is designed to mount in a 19-inch equipment rack/cabinet, taking up only 2 rack units (RUs) of space or 3.5” of vertical space. All cooling is back to front, so no additional vertical space is required in the rack for cooling. The mainframe has removable rack mounting ears, which may alternately be placed near the bottom of the mainframe for ease in mounting this unit on a wall, such as in a telephone closet, or on the back for rear rail mounting reinforcement.

The mainframe has connections for audio inputs and speakers, as well as status monitoring outputs such as fan speed, amplifier (heatsink) temperature and amplifier status signals. The fan speed and temperature outputs are voltages whose values are proportional to speed or temperature, respectively. The mainframe also has individual input level controls for each of the possible 4 channels. The audio inputs on the back are made via plug-in lugless compression-type screw terminals. Also, the speaker connections are made via larger scale terminals of the same type. The power amp cards slide in from the front and have individual power switches on the front along with power and signal presence LEDs.
