The HERITAGE AUDIO DTT73 expands the range of applications for On Stage use, portable systems, hotel rooms, On Location recordings, etc.\u003cbr\u003eParticular attention has been paid to the internal worldwide 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 sockets for simultaneous use with instrument amplifiers. A ground lift 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. Higher gain positions gradually have higher impedances, optimal for low-gain ribbon microphones.
