The TT-73 expands the range of applications for use On Stage, portable systems, hotel rooms, On Location recording, etc.\u003cbr\u003eParticular attention has been paid to the internal power supply, which has been custom-designed to operate near audio transformers without induced noise.\u003cbr\u003eA new feature in the range of desktop units is the implementation of DI THRU jacks for simultaneous use of instrument amplifiers. A ground switch prevents any ground loops from introducing hum into the audio when using these.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eMicrophone Input Impedance: HI, minimum 1200 Ohm, LO, minimum 300 Ohm.
