Lowell MA30-RK Rack-Mount 30W Mixer/Amplifier, 70V

The mixer integrates a 30W power amplifier with speaker outputs supporting 4ohms, 8ohms, 25V, and 70V configurations through screw terminals. Operated by 120VAC 60Hz, the primary AC input is safeguarded by a rear circuit breaker, while a separate circuit breaker protects the rear receptacle. The front panel encompasses three input channels (MIC/TEL, PROGRAM, AUX1), along with BASS and TREBLE controls, a power active LED, and an output level LED. The inclusion of rackmount brackets enhances installation flexibility and convenience.
