MIPRO MI-909T Digital In-Ear Transmitter for Wireless

MiPRO's MI-909T is a digitally-encrypted rack transmitter that is used in both live applications and professional installations, such as language interpretation. It operates in a 64 MHz wide bandwidth and allows multiple preset compatible channels operation. The transmitter has high dynamic range stereo audio inputs, delivers up to 100mW output power, and is able to withstand professional audio mixers' maximum output levels. Menu settings allow input sensitivity, encryption, EQ DSP processors to be set-up via a rotary control knob. A built-in Scan function enables auto-scanning for an open, interference-free frequency and that frequency can sync with the bodypack receiver via the ACT button.
