Heritage Audio DTT-73 Dual Tabletop Mic Amplifier

The Heritage Audio DTT- 73 is a dual channel desktop microphone preamp and DI derived from the iconic 1073.


The Heritage Audio DTT-73 delivers the iconic 1073 sound vibrant and colourful. Both channels feature separate input and output level controls which allow you to drive and saturate the input to obtain the rich and colourful sound of vintage consoles. Each channel offers up to 80dB of gain, capable of powering any condenser, dynamic or ribbon microphone.


The DTT-73 is a portable unit that will give your sound source a huge dose of vintage sound thanks to the use of Carnhill input and output transformers. Both DI inputs are placed before the input transformers which impart some colour to any instrument, be it a guitar, bass or synthesizer. Two DI Thru jacks are included and let you plug an instrument into an for greater tone and flexibility in the studio or on stage.
