HADMA73 - ’73 Stylle Dual Mic Preamp / DI
The DMA-73 is a dual-channel mic pre with a sound and circuitry almost identical to that of the legendary Neve 1073. Perfect for old ribbon mics, the 80dB microphone preamp re-creates faithfully that vintage sound. The Line mode with 50dB of gain allows for reamping of prerecorded tracks and it´s perfect for adding some class A color to lifeless recordings.
Two XLR mic and line inputs on the rear and two ultra-high-impedance J-Fet direct inputs and a 20dB pad to avoid overloading will handle any source. The DMA-73 is packed in a standard 19” howsing with an external low nois powersupply.
