The wide dynamic range of high-resolution digital recording has remained largely unexploited simply because pre-amplifier technology cannot deliver an equivalent dynamic range. More significantly, limited headroom pre-amplifiers may also degrade or "squash" the dynamic range of the sound source, en-route to the recording medium.
From the silence of the noise floor to the onset of clipping, the Drawmer 1962 provides an input dynamic range of more than 133dB, eclipsing the performance of other front-end devices and coming close to theoretical perfection.
A minimal signal path connects a matched pair of pre-amps directly to the high resolution 24-bit A/D converters. Further innovative processing circuitry including Drawmer's two-band Dynamic Spectral Enhancement (DSE), Fine-Tune EQ, Tube Drive and Transparent Limiting can be inserted in the signal path for creative applications. In addition, the 1962 uses Drawmer's digital 'bit-splicing' techniques to facilitate 24-bit recording on the Tascam and Alesis ADAT 16-bit digital multitrack machines. 
The Drawmer 1962 is the 'one-box solution' for committing audio directly to the digital domain.
Sample Rate: This selects 48.0kHz, 44.1kHz or EXTERNAL CLOCK for synchronising to other digital devices.
Word Length: The standard D62/T provides 16-, 18-, 20- or 24- bit Word Length (bit resolution) with AES/EBU, SPDIF and Tascam™ TDIF-1 digital outputs. The optional D62/A provides the Alesis ADAT™ optical interface.
Dither: This switch provides a choice of 11 types of noise shaping (position12 is Dither-off). Positions A, B, C and D are playback modes for high-resolution recordings from digital recorders.
Source: When Chs is selected channels 1 and 2 are sent directly for A/D conversion. MIX inserts the channel PAN controls into the signal path and enables up to three other stereo analogue signals, via rear panel inputs, to be mixed with channels 1 and 2 before A/D conversion.
