Drawmer Masterflow DC2496

Product Description

The Drawmer DC2496 is an extremely sophisticated, high resolution analogue to digital converter designed for use in demanding recording and broadcast applications. Both analogue (balanced XLR) and digital (AES/EBU, S/PDIF, ADAT 8 Channel light pipe and TDIF 8 Channel) I/O is provided as standard. The audio converters are 24bit and the digital output can be either 16, 18, 20, 22 or 24bit at sample rates of up to 96kHz. Noise shaped dithering is included and Word Clock input and output is available.

Why 96kHz? Digital processing has until now been confined to 48kHz sampling frequency. In order to achieve the required bandwidth for professional audio, a very severe low pass filter at 23kHz is required to separate analogue signal frequencies from the clock frequency otherwise unpleasant aliasing will occur. This requires the use of a FIR digital filter which is part of the A/D and D/A converters. Unfortunately these filters cause what is known as time smear, where short transients are smeared over a longer time period giving loss of HF detail. At 96kHz sample frequency, the low pass filter is less severe and at twice the frequency, so time smear is considerably reduced.

A second important consideration is the increased audio bandwidth up to 40kHz. This allows harmonics which extend above human hearing to be generated and preserved. These harmonics, although not audible themselves, make a contribution to the sound quality.
