RDL PM-1T Pole Mount TrayThe 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.
