Heritage Audio DTT73 - Desktop Dual Mic Preamp and DI

The Heritage Audio DTT73 is a dual desktop mic pre. The DTT 73 is in essence a re-formatted DMA73, designed to be used on stage, in portable systems, in hotel rooms, on location recordings and more. The DTT-73 allows musicians to provide FOH engineers with 1072-driven line level signals. The compact design and handle make the unit easily portable to any recording location. A new addition to the desktop units is the DI THRU jacks which allows for simultaneous use of instrument amplifiers.

Specifications

• 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)
• Maximum gain: Slightly greater than 80dB
• Noise: Less than -100dBu.
