Heritage Audio TT73 - Desktop Mic Preamp and DI

The Heritage Audio TT73 is a table top reformatted DMA73. The Table top format widens the range of applications to on stage, portable systems, on the road, on location recording and much more. The TT 73 can be used to provide a 1073-driven line level signal to the FOH, or provide studio quality recordings where ever you need to record whether it be a hotel room or on a location recording. 

The unit also contains a THRU jack for simultaneous use of instrument amplifiers = and a ground lift switch which prevents any ground loops introducing hums in the audio when using these.

  • Microphone input impedance: HI, 1200 Ohm minimum, LO, 300 Ohm minimum. Higher gain positions gradually have greater impedances, optimum for lo gain ribbon mics. Input is transformer balanced and floating.
  • Line input impedance: 10K Ohms bridging, transformer balanced and floating.
  • DI input impedance: Greater than 2 Megohms, unbalanced.
  • Output impedance: Less than 75 Ohms, transformer balanced and floating, to drive a load of 600 ohms (factory terminated).
  • Maximum output: Greater than +26dBu into 600 ohms.
  • THD: Less than 0.025% at 1 Khz, less than 0.05% at 100Hz.
  • Frequency response: 20Hz ( +0.3dB ) to 20Khz (-0.2dB)
