Heritage Audio Super 8 - 8 Channel Mic Pre with ADC

Heritage Audio Super 8 - 8 Channel Mic Pre with ADC

The Heritage Audio Super 8 is an 8 channel Microphone preamp with ADC that provides the classic 'british sound'. The Super8 can capture MIC, LINE or INSTRUMENT level signals and with the on board ADC, have the signal instantly digitised and sent to your DAW.

The built in analog to digital converter uses the latest technology to offer pristine conversion at a user selectable sampling frequency. The Súper 8 can either be the Master or Slaved to another unit as there is a BNC IN & OUT for reliable syncing. It even offers an alternate route to the converter via a DB25 connector to expand the unit´s flexibility.

The Súper 8 offers a fantastic, compact solution for when several high quality preamps and top class conversion is needed.

Using our Class A 73 Preamp building experience we were able to fit 8 MIC/Line preamps into a sturdy 2 unit rack. All 8 are faithful to our 3 stage all Class A design with Carnhill transformers fitted at the input and the output. The first two channels also include our high quality JFET DI as well as a fully sweepable Lo-cut filter. All 8 channels include switches for 48 V, Line, Lo-cut (-3 dB at 82 Hz) and Phase.

There is built in analog to digital conversion available on 3 different digital formats: ADAT, AES/EBU and SPDIF with BNC connectors for reliable word clock syncing. Selectable sampling frequencies from 44.1 kHz to 192 kHz. 

Not only can the MIC/Line Preamp outputs be directly sent to the DAC, but there also exists the possibility of choosing an alternative input, per channel, for the digital conversion, making this an extremely flexible unit. This can really come in handy if you need to output the preamps to an EQ or compressor before returning them for digital conversion.
