26 channels of AES/EBU - MADI conversion in each rack unit. Versions available for 110ohm XLR and 75ohm coax.
Multi-Channel Converters
The DM714 and MD704 are now available with 75ohm BNC connections for all digital audio inputs and outputs as well as AES digital sync input and output.
DM714 and MD704 AES/EBU Converters
High quality digital audio format conversion with built-in sample rate converters.
The DM714 and MD704 24-bit converters provide MADI conversion to/from digital (AES/EBU) equipment such as digital multi-track recorders, digital audio workstations, audio routers, and facility patching systems. Both converters are two rack spaces high and are housed in a stainless steel chassis with machined, heavy aluminum front panels.
The DM714 converts incoming AES/EBU digital audio to MADI. In addition to the 24 input channels (12 AES/EBU pairs), there are two auxiliary analog inputs (XLR) and one auxiliary digital input pair (S/PDIF or AES/EBU). Each main AES/EBU input is automatically evaluated for sample-rate conversion. The incoming sample rate is compared with the internal rate. If they are the same, no conversion occurs. If the rates differ, sample-rate conversion is activated. The samplerate conversion range is 32-56 kHz.
The MD704 converts incoming MADI signals to 24 digital output channels (12 AES/EBU pairs). In addition to the 24 analog outputs, there are also two auxiliary analog outputs (XLR) and one auxiliary digital output pair (S/PDIF or AES/EBU). The main 24 outputs can be bit-depth converted from 24 to 20 or 16 bits.
AES/EBU and Word Clock external digital sync inputs on both units provide synchronization to digital systems. Sample Rate Source and Sample Rate are automatically sensed by both units. Supported sample rates include 44.1, 48, 88.2, and 96 kHz. In addition, pull-up and pull-down rates for the standard sample rates, as well as custom sample rates are available.
Four-segment front panel LEDs monitor the input/output signal strength. LED meter segments indicate -42, -18, -6 (green) and -0.005 dBFS (red). The analog inputs and outputs can be calibrated from the front panel of each unit.
