The PM-1T is a tray that mounts above a projector using a standard (1.5" I.D.) round projector pole or any smaller round or rectangular pole. The tray accommodates up to two FP-PA20 Audio Power Amplifiers (for stereo operation) and two PS-24U2 Power Supplies. There is adequate space remaining for associated STICK-ON and TX series modules. If two FP-PA20 type amplifiers are not used, multiple STICK-ON, FLAT-PAK and TX series modules may be mounted. Examples of typical tray-mounted modules may include STICK-ON series power amplifiers. Headphone amplifiers, VCA modules, line amplifiers, video amplifiers or distribution amplifiers may also be mounted.
