D.O.TEC® MADI.SRC offers best quality sample rate conversion of a complete MADI stream (64 audio channels) in realtime. The device supports any source and destination sample rates from 30 kHz to 50 kHz and their multiples (48k/96 kFrame, 56/64 channels). High end chips with a THD+N > 140dB and a frequency response linearity better than 0.025 dB guarantee excellent sound quality.
Inputs and outputs are layed out with both optical (SC multi-mode) and coaxial (BNC) connectors and work in parallel. Thus both outputs carry the converted input signal and can be distributed twice. If required the signal format can be converted from/to optical/coaxial by using the SPLIT.CONVERTER.
The MADI.SRC can be used whereever sample rate conversion with highest sound quality is requested. The stream is processed in realtime and all channels provided at the output will be phase and sample accurate to each other.
By activating the extra ordinary Split Mode, the inputs and outputs can be used in combination to allow for conversion of more than 32 (@96 kHz) or 16 (@192 kHz) channels, depending on the SRC's setting.
Synchronisation can be achieved via wordclock or AES3id (AES11), video reference, the MADI input signal as well as the internal clock.
Due to its comprehensive features, the MADI.SRC is also a versatile device beyond 'simple' sample rate conversion. For instance in an environment where two digital systems do not use the same word clock source (e.g. FOH or OB van). The MADI.SRC can be used as decoupling unit to connect both asynchronous systems without any loss in sound quality (see also: press release "Rock am Ring").
With the SRC switched off, the device works as a simple format converter and supplies the different MADI formats at the output ports (48k/96k Frame, 56/64 channels).
The MADI.SRC offers highest reliability by two phase redundant power supplies with inlets and switches on the rear panel.
