Mipro MI-909T

The MI-909T is a rugged digitally-encrypted rack transmitter. It operates in a 64 MHz wide bandwidth and allows multiple preset compatible channels operation. Delivering up to 100mW output power, it has high dynamic range stereo audio inputs 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, once selected, that frequency can sync with the bodypack receiver with a simple push of the ACT button. The MI-909T is ideal for both live applications and professional installations such as language interpretation.
