Project Description

DirectOut Technologies MADI.9648

A bidirectional MADI transcoder that synchronously converts 128 channels between 1FS 48 kHz and 2FS 96 kHz MADI formats in live sound systems.

  • Bidirectional MADI transcoder
  • Simultaneous up- and down-conversion of 128 audio channels
  • Four independent 32-channel synchronous SRC blocks providing:
    • up-conversion of two 64-channel MADI streams at 44.1/48 kHz to four 32-channel MADI streams at 88.2/96 kHz
    • down-conversion of four 32-channel MADI streams at 88.2/96 kHz to two 64-channel MADI streams at 44.1/48 kHz
  • Auto-detection of MADI formats: all channel counts, sample rates and frame rates are allowed
  • Simple to install: no setup required
  • Six coaxial (BNC pairs) MADI ports – inputs and outputs
  • Two dual-SC, multi-mode fibre optic MADI ports – bidirectional
  • Front panel LED display for overview of signal presence and MADI formats
  • 1U rack mounting unit
  • Dual PSUs for redundancy
  • USB port for firmware updates

The DirectOut MADI.SRC is also available if asynchronous decoupling sample rate conversion is required.

There are several other units which convert between MADI and other audio formats: ANDIAMO 2, ANDIAMO 2.DA and 2.AD handle MADI and analogue conversion; the ANDIAMO.AES converts between MADI and AES3 and the ANDIAMO 2.XT between MADI and both AES3 and analogue, with SRC as an option. The MONTONE.42 is a MADI-to-Ethernet bridge with full AES67 compliance.

Description

DirectOut Technologies’ MADI.9648 is a MADI format converter intended for rapid installation in live sound systems and broadcast sound applications.

The architecture of the MADI.9648 is based on four independent sample rate conversion blocks: two are used for up-conversion and two for down-conversion. The SRCs always take their master clock reference from one particular source in each pair of input ports.

Each synchronous up-conversion SRC block allows a MADI source at 44.1/48 kHz, with up to 64 audio channels, to be converted to a pair of MADI streams at 88.2/96 kHz, each with up to 32 channels, locked to the input MADI stream. As there are two up-conversion blocks, this enables a total of 128 channels of audio in 44.1/48 kHz MADI format to be interfaced to a digital mixing console operating at 96 kHz sample rate.

Simultaneously, each synchronous down-conversion SRC block allows a pair of 88.2/96 kHz MADI streams, each with 32 channels, to be down-converted to a single 44.1/48 kHz, 64 channel MADI output, locked to one of the two inputs. This provides an interface for console auxiliary sends, cue feeds, cleanfeeds as well as primary outputs. Again, as there are two down-conversion blocks, up to a maximum of 128 audio channels can be handled. The down-converter outputs are dual, and are available on two separate connectors for ease of distribution.

A total of eight MADI ports is provided. Ports 1 to 4 each comprise a pair of BNC connectors, providing an input and an output at 88.2/96 kHz. Ports 5 and 6 also each comprise a pair of BNC connectors, providing an input and an output at 44.1/48 kHz. Ports 7 and 8 are separate bidirectional SC-type optical ports at 44.1/48 kHz.

A great virtue of the MADI.9648 is that it has no controls and requires no setup. All MADI format parameters are auto-detected and the unit self-configures accordingly. Channel counts of 56 or 64 (at 44.1/48 kHz) and 28 or 32 (at 88.2/96 kHz) are compatible, as are 1FS 48k and 2FS 96k frame rates.

A set of front panel LEDs indicate signal presence and sample rate for each input format, as well as confirming the clock rate source.

A USB port is provided to enable firmware updates.

MADI.9648 occupies 1U of rack space with a depth of 200 mm. Dual redundant universal PSUs with independent IEC inlets are fitted for maximum reliability; only one PSU is wired via the front panel power switch to ensure continued operation in the event of accidental switch-off.
