SAMSON / HIGH RISE MIC GAIN BOOSTER

A unique microphone booster equipped with two-stage gain switching, an HF LIFT switch, and a LOW CUT switch. When HF LIFT is turned ON, the high frequencies are emphasized, resulting in a clear sound.

Overview
■Microphone booster
■LOW CUT (120Hz) switch
■GAIN switch (+30dB | +20dB | +20dB/HF LIFT)
■48V phantom power drive *Cannot be used with condenser microphones
