Drawmer DC2476 all-digital stereo mastering processor
This is an amazing processor. It is slightly used but IN GREAT SHAPE! I'm trying to get some footing for my family so I'm selling to keep them secure.Blessings and Immediate Payment is Required. I will ship to Canada and Mexico for 50 more on the shipping. I do not accept bidders with zero feedback. If payment is not made immediately Thank You and Blessings! Drawmer DC2476 The Drawmer DC2476 is an extremely sophisticated, all-digital stereo mastering processor designed for use in demanding recording and broadcast applications. Both analogue (balanced XLR) and digital (AES/EBU and S/PDIF) I/O are provided as standard. The audio converters are 24-bit and the digital output can be either 16, 18, 20 or 24-bit at sample rates of up to 96kHz. Noise shaped dithering is included and Word Clock input and output is available. Main Features 24 bit A/D - D/A conversion 32, 44.1, 48, 88.2 or 96kHz In/Out sample rate Multi band 'Bootstrap' compression Gain Normalisation for maximum loudness Multi band expansion and limiting Five band digital EQ with �18dB range Dynamic EQ with full band compressor Multi-band tube modelling for musical tone shaping De-essing Word Clock In/Out, Midi In, Out and Thru Three band stereo width control Expert factory patches and user memory Autofade PCMCIA slot for parameter transfer to other Drawmer DC2476 units AES/EBU, SPDIF digital input / output connectors Balanced XLR analogue input / output connectors
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. Finally, the user interface has been designed to make the Drawmer DC2476 as simple to operate as possible. In fact, once you�ve got used to using the cursor buttons, the Adjust knob and the Adjust knob push switch to move around the various screens and their parameters, operation is almost entirely intuitive. Custom graphics are used wherever possible to monitor the processor function and its adjustments while front panel LED bargraph meters constantly monitor the input and output signal levels, limiter activity, plus the amount of gain reduction being applied in each of the three frequency bands. Effects: The signal chain comprises six blocks in addition to the Input and Output sections. The Dynamic EQ and Equaliser blocks are of necessity full-band (they affect the entire signal), while the Expander, Compressor, Limiter and Tube Drive sections that follow are all three-band. Multi-Band Processing: The main purpose of the split band section is to allow the three different parts of the audio spectrum to be treated independently so as to minimise side effects, but each of the dynamic processes may be adjusted differently in each of the three bands if required. This opens up many creative possibilities for introducing level dependent spectral changes. The user may adjust the two crossover points that define the three frequency bands into which the signal is split prior to processing. The crossover frequencies may be accessed from the second page of any of the split-band effects blocks. Gain Management System: Since both the Dynamic EQ, Compressor and Parametric Equalisers ...
