DMI-AMM

This card offers both the SD-Range and the S-Series consoles 48 channels of automatic microphone mixing which can be used in any console input channel.

When dealing with live sound scenarios that involve several live microphones with unpredictable dialogue, mixing them can be a challenge for an engineer. DiGiCo are proud to offer the DMI-AMM (Automatic Mic Mixing) as a versatile solution for these issues.

The DMI-AMM system works by instantly fading up a microphone’s gain when one person begins to speak and reducing the gain of the other microphones. When the speaker pauses, all microphone levels return to medium gain, collectively matching the level of one microphone with the full gain share. The resulting effect is as if all speakers are sharing one microphone. When several people talk at once, the gain is shared between the speakers. Each channel is given a Share Meter, which is shown in percentage, not dB. This makes it easy to see what channels are taking the majority of the gain.

The DMI-AMM also allows adjustment of the relative sensitivity (or weighting) of the AMM on a per channel basis. This means that should one of the speakers be quieter than the others, they still have the ability to “take over” the system. Furthermore, the card features a vital noise floor control that imposes a lower limit on the level detector of all mics in the AMM to prevent a noisy mic from catching a disproportionate share of the gain.

This card offers both the SD-Range and the S-Series consoles two independent 48 channel automatic microphone mixers which can be used on any console input channel. Both the S-Series and SD-Range allow a Virtual AMM so that the AMM routing and parameters can be set before a card is inserted.

Main Features

• Two independent 48 channel automatic microphone mixers
• Weighting control on a per channel basis
• Share meter in percentage to show which channels are taking the majority gain share
• Noise floor control
• Simple integration into both the S-Series and the SD-Range software
• Virtual AMM to set up a session before the card is present
• Compatible with S-Series, SD12 and Quantum Range

DMI-ADC

This card provides 16 analogue inputs on 2 x 25 way “D” connectors. The ADC card is a line card only. There is no microphone amplifier or phantom power available. There is no gain control function for these inputs (only digital trim). Maximum input level +22dBu.

As a simple solution to expanding the local i/o of the S-Series, DiGiCo offer the DMI-ADC and the DMI-DAC. Both use 2 x 25 way “D” connectors to add either 16 analogue inputs or 16 analogue outputs. Both cards are compatible with S-Series, Quantum Range, SD12, Orange Box and 4REA4.

Main Features

• 16 analogue inputs
• 2 x 25 way “D” connectors
• Compatible with S-Series, Quantum Range, SD12, Orange Box and 4REA4

DMI-AES

This card provides 16 Inputs (8 pairs) and 16 outputs (8 pairs) on 2 x 25 way “D” connectors. All AES inputs are provided with sample rate conversion (SRC) by default. All AES outputs are synchronised to the mixer system clock.

Developed by the Audio Engineering Society (AES) and the European Broadcasting Union (EBU), this digital audio format was originally developed in 1985 and was the first professional digital audio format to gain widespread acceptance. There have been several revisions over the years. Also known as AES3 or IEC-60958 Type I, the data protocol includes up to two channels of up to 24-bit audio running at sample rates up to 96 kHz.

Multi-channel digital audio formats such as MADI have become popular, but AES3 is still a very useful format to distribute stereo signals (such as L/R mixer output) or to integrate stereo signal processors such as reverbs.

The DMI-AES provides 16 Inputs (8 pairs) and 16 outputs (8 pairs) on 2 x 25 way “D” connectors. All AES inputs are provided with sample rate conversion (SRC) by default. All AES outputs are synchronised to the mixer system clock.

Main Features

• 2 x 25 way “D” connectors
• 16 inputs (8 pairs) and 16 outputs (8 pairs)
• Sample rate conversions on all inputs
• Compatible with S-Series, Quantum Range, SD12, Orange Box and 4REA4

This card provides 16 output channels at 48kHz (with SRC) and Supports Aviom's proprietary A-Net Pro16 protocol. It has 1 Ethercon connection and faceplate DIP switched for Stereo output selection.

The DMI-AVIOM allows easy integration with Aviom’s personal monitoring systems through the use of their A-Net protocol. The card provides 16 output channels (8 stereo) at 48kHz with inbuilt sample rate conversion for seamless compatibility with consoles running at 48kHz or 96kHz and supports Aviom’s proprietary A-Net Pro16 protocol. It has 1 Ethercon connection and faceplate DIP switches for stereo output selection.

Main Features

• 16 output channels (8 stereo)
• Faceplate DIP switches for stereo output selection
• Inbuilt sample rate conversion
• Compatible with S-Series, Quantum Range, SD12, Orange Box and 4REA4

DMI-DAC

This card provides 16 analogue outputs on 2 x 25 way “D” connectors DAC card is line level only. Maximum output level +22dBu (Digital Full Scale)

As a simple solution to expanding the local i/o of the S-Series, DiGiCo offer the DMI-ADC and the DMI-DAC. Both use 2 x 25 way “D” connectors to add either 16 analogue inputs or 16 analogue outputs. Both cards are compatible with S-Series, Quantum Range, SD12, Orange Box and 4REA4.

Main Features

• 16 analogue outputs
• 2 x 25 way “D” connectors
• Compatible with S-Series, Quantum Range, SD12, Orange Box and 4REA4

This card can be used to connect another DiGiCo device that uses RJ45 Standard MADI (64 channels in and out) at 48KHz or 96KHz or an SD Series DiGiCo Rack with the appropriate connector (D-Rack, D2-Rack)

MADI (Multichannel Audio Digital Interface) is arguably one of the most popular protocols for transmitting high channel counts in professional audio. This is partially due to its ease of use, and the ability for cables to be run long lengths with minimal signal loss. Originally only capable of transmitting 56 channels, MADI is now capable of transmitting up to 64 channels.

DiGiCo offers two MADI DMI cards, each with different connector types. Both the MADI-B (BNC) and the MADI-C (RJ45) cards can be used to connect up to 64 channels of audio in and out at both 48kHz and 96kHz. At 48kHz, the B connection can be used as a redundant audio stream. Should the A stream fail during use, the B stream will seamlessly take over. At 96kHz, the B connection must be connected to provide the full channel count.

Main Features

• RJ45 connection
• 64 channels in and out at 48kHz and 96kHz
• Redundancy if working at 48kHz
• Only for use with DiGiCo audio over Cat5 devices
• Internal switches to determine whether connected to a console or a rack
• Compatible with S-Series, Quantum Range, SD12, Orange Box and 4REA4
