Standing for DUAL TABLETOP 73, the DTT-73 is the dual channel version of the TT-73 Mic Preamp. The DTT-73, widens the range of application to On Stage use, portable systems, hotel rooms, on-location recordings or wherever inspiration strikes.

Now, you are able to give 1073-driven line levels to FOH engineers, using the front panel DI inputs. While on the road, you can record at the same studio quality level from hotel rooms and more. Stage microphones can be brought up to line level without using long cable runs. These are just some of the possibilities.

Special care has been taken with the internal worldwide power supply, which has been custom engineered to operate close to audio transformers with no noise induced.

New to Heritage Audio's range of tabletop units is the implementation of DI THRU jacks for simultaneous use of instrument amplifiers. A ground lift switch prevents any ground loops introducing hum in the audio when using these.

The combination of wood and RAF blue gray steel makes the tabletop units aesthetically stand out in any professional recording environment and will bring your pro or semi pro facility the touch of class your customers are looking for.

A Single Channel Version is also available.

Microphone input impedance: HI, 1200Ω minimum, LO, 300Ω minimum. Higher gain positions gradually have greater impedances, optimum for lo gain ribbon mics. Input is transformer balanced and floating.
Line input impedance: 10KΩ bridging, transformer balanced and floating.
DI input impedance: Greater than 2 Megohms, unbalanced.
Output impedance: Less than 75Ω, transformer balanced and floating, to drive a load of 600Ω (factory terminated).
Maximum output: Greater than +26dBu into 600Ω.
THD: Less than 0.025% at 1 Khz, less than 0.05% at 100Hz.
Frequency response: 20Hz ( +0.3dB ) to 20Khz (-0.2dB)
Maximum gain: Slightly greater than 80dB
Noise: Less than -100dBu.
