Drawmer Unveils A2D2 AES Grade 1 Dual Ooutput A/D Converter, M-Clock Plus & M-Clock Lite

Drawmer USA has unveiled the A2D2 AES Grade 1 Dual Ooutput A/D Converter, M-Clock Plus and M-Clock Lite.

A2D2 AES GRADE 1 DUAL OUTPUT A/D CONVERTER


The A2D2 is a stereo A/D converter giving simultaneous dual stereo outputs at different selectable sample rates from 44.1kHz to 192kHz – so it is possible to have a main output at, say 192kHz with another at 44.1kHz as a low resolution copy.

Features:
• Accurate 24 segment peak reading LED bar meters shows incoming signal level from -50dBfs to 0dBfs plus separate overload LEDs.
• Dual input configuration allows either a fully variable input level from -2dBu to +28dBu via front panel rotary controls or 24 turn precision presets for a fully calibrated input.
• Each digital output has selectable word length of 16 or 24 bits, with automatic dither generation.
• The internal low jitter clock generator is Grade 1 AES standard.
• External clock input.
• 3 word clock outputs to allow the A2D2 to act as master clock generator.
• Burr Brown analogue input stages.
• The A2D2 uses a linear power supply to minimise interference with the internal clocks.

M-CLOCK PLUS AES GRADE 1 MASTER CLOCK/DUAL SAMPLE RATE CONVERTER


M-Clock Plus is a high stability master clock generator offering clock rates from 44.1 to 192kHz, coupled to two sample rate converters, which allow material to be re-sampled and syncronised to the selected high precision clock.

In addition to the internal clocks, M-Clock Plus can sync to either external word clock or clocks from AES/EBU signals. Precision clock frequency measurement and display indicates the exact frequency of the selected clock, whether internal or external, to an accuracy of 2ppm.

Features:
• M-Clock Plus has an external word clock input and an AES11 input which retrieves the clock from an AES audio signal.
• Each sample rate converter has selectable AES, SPDIF or TOSLINK inputs, with simultaneous AES, SPDIF and TOSLINK outputs. This allows many possibilities for format conversion as well as sample rate conversion.
• Sample rate converter #2 has inputs on the front panel for easy access.
• User selectable word length of 16 or 24 bits with automatic dither generation – particularly valuable for 16 bit word lengths at low signal levels.
• 10 word clock outputs – 8 at the rear and 2 at the front for easy access.

M-CLOCK LITE AES GRADE 1 MASTER CLOCK


It is now widely accepted that one of the essential requirements for high quality digital recording is a first class, high stability master clock generator. These can be complicated devices with many added features, which although useful, may be surplus to requirements. The aim of M-Clock Lite is to provide a simple, high quality clock generator, which is forward compatible with high speed clocks predicted for the future. M-Clock Lite features an AES Grade 1 master clock generator, meaning that the generated clock has a long term frequency accuracy of +/- 1ppm.

Features:
• M-Clock Lite offers clock rates of 44.1, 48, 88.2, 96, 176.4, 192, 352.8 and 384kHz at extremely low jitter.
• An external clock input allows the user to select an alternative clock source without having to re-route clock cables.
• 10 Outputs are provided, 8 at the rear and 2 for easy access on the front panel.

No pricing or availability has been announced. More information on the Drawmer A2D2 AES Grade 1 Dual Ooutput A/D Converter, M-Clock Plus and M-Clock Lite
