Based on a proprietary DSP mix platform, the CDC four:m is a fully featured versatile digital console with the look, feel and simplicity of using an analogue console. The CDC four:m builds upon the CDC four feature set by providing the user with GEQs on all aux busses in addition to the master L and R, plus the inclusion of a 6 x 4 matrix with GEQ, PEQ and dynamics processing.

Due to its audio performance the CDC four:m excels equally well in recording applications as it does in its primary function as a live sound console used for concert touring, corporate AV, schools and houses of worship. It also has the advantage of being rack mountable making it ideal for situations requiring up to 56 channels in a 19” rack.
The CDC four:m brings Cadac sound and build quality to the compact, rack mountable, digital console market providing a high-quality solution for all applications and budgets.
The CDC four:m features 16 fully motorised channel faders, high resolution TFT colour display and fully recallable scene memory. Cadac’s signature sound quality is achieved by using specially developed remarkably low distortion EQ filters, true analogue sounding compressors, 96 kHz 24-bit Delta Sigma AD/DA converters and fourth generation 32/40-bit floating point SHARC processors.

Multitrack recording is achieved via an optional MC MADI network bridge, while input channels can be increased for live applications with the optional MegaCOMMS card and the CDC I/O 3216 stagebox, which provides an additional 32 inputs and the 16 outputs up to 150 metres (492ft) away on stage.
The CDC four:m, which has GEQs on all aux busses in addition to the master L and R, and when used in conjunction with a CDC I/O 3216 the console’s 6 x 4 matrix, with GEQ, PEQ and dynamics, are available on the stagebox’s outputs.
With Cadac’s iPad App – TabMix – there is the ability to control the major features of the console remotely, making both sound check and show time easier as it frees the console operator from the confines of the mixer’s location.
Cadac’s analogue mic-amps have been universally acclaimed as the premium mic-amp in the industry.
The design brief for a digital console was simple and consistent with the brand’s ethos for over 50 years – audio first.
Cadac’s digital consoles bear the hallmark of their analogue origins which can be traced back beyond the now legendary J-Type to those classic consoles of the golden age of recording studios. The audio performance still retains its traditional wide dynamic range and low noise floor through a combination of unique analogue emulating algorithms and the latest 24-bit / 96 kHz Delta Sigma AD/DA convertors.
Another key to the Cadac sound is the attention paid to latency management – a major factor in digital audio performance and over looked by a majority of other digital consoles.
This video provides an overview of Cadac’s CDC four:m latency management
All digital consoles take time to process audio. Combining signals with different paths and processing, most digital consoles when summing the multiple signals will be partly out of phase. Cadac digital consoles have an extensive automatic latency management system which manages all internal routing and associated processing latency, which means that all audio samples are synchronised before summing, resulting in absolute phase coherency at all outputs.
The CDC eight, CDC seven-s, CDC six and CDC five on a Cadac’s MegaCOMMS network have a latency of under 0.4 milliseconds, from analogue inputs on stage, through the console, to analogue outputs on stage. This makes them perfect for in-ear monitoring. All inputs and all outputs are time aligned to sample accuracy – no matter the routing or where they are located in the network.
Cadac’s Console Remote Manager iPad App – TabMix – provides wireless remote control of the key functions of the CDC four:m. Once a wireless router is connected to the console there is no difficult setup procedure as the App automatically detects and selects the active console type.
With TabMix’s intuitive graphical user interface and real-time command of the console, sound check becomes less of a chore and more of a creative process.
TabMix is free to download from Apple’s App Store.
The MegaCOMMS card is the audio interface for the CDC four:m that allows the consoles to take advantage of Cadac’s MegaCOMMS audio protocol. The optional card enables the CDC four:m to connect to Cadac’s range of stageboxes permitting the input count to rise to 64 along with, up to 26 outputs on stage. The card simply slots in the rear of the console and connection to the stagebox is via 2 co-axial cables of up to 150 metres (492 feet) in length. This neatly dispenses with the need for heavy, bulky and expensive analogue multicores.

The CDC I/O 3216 is the ideal stagebox for the CDC four:m. It is a 4U fixed configuration unit featuring 32 mic / line analogue inputs and 16 XLR analogue outputs permitting the input count to rise to 64 along with 16 outputs selected from the available 26, on stage.
The stagebox is connected to the CDC four:m via the MegaCOMMS card allowing the console to take advantage of Cadac’s propriety low latency MegaCOMMS audio network protocol.
The CDC I/O 3216 can be located up to 150 metres (492 feet) away from the console using just a pair of co-axial cables.
When the CDC I/O 3216 is used in conjunction with the CDC four:m the console’s 6 x 4 matrix outputs, with GEQ, PEQ and dynamics, are available on the stagebox’s outputs.

The mic-pres can be controlled remotely from the console and the outputs can also be assigned from the console. To complete the user interface there are signal present, clip and phantom power indication plus mute indication for the outputs.
By using the MegaCOMMS interface card the CDC four:m can also take advantage of either of Cadac’s audio network bridges; the CDC MC MADI or CDC MC Dante. This allows the CDC four:m to be integrated into third party MADI or Dante audio networks.
The MC MADI convertor will allow you to stream the input channels to your DAW (with the appropriate computer interface) and make multi-track recordings quickly and easily. Recordings can be made at the standard 48 kHz MADI sample rates or at 96 kHz for more demanding applications. Multi-track recordings can then be played back through the CDC four:m for remixing or for “virtual sound check” when the live artiste is not available.
The CDC MC MADI is a MADI to MegaCOMMS audio network bridge allowing the seamless integration of MADI audio streams into a MegaCOMMS audio network. The 1U unit can operate at 96 kHz or 48 kHz and can handle up to 64 inputs and outputs and is equipped with 128 channels of SRC as well as its own independent word clock.
The MC MADI comes as standard with dual PSUs ideal for mission critical applications. The MADI audio connections are handled via co-axial and optical. To aid with configuring the MegaCOMMS network the unit’s co-axial ports glow either red or blue for Rx (receive) or Tx (transmit) – a real boon for speeding up low light set-up.
The CDC MC Dante is a 1U Dante to MegaCOMMS audio network bridge enabling Dante units to be incorporated in to the MegaCOMMS audio network. The unit can work at either 96 kHz or 48 kHz and can handle up to 64 inputs and outputs.
The MC Dante also has 128 channels of SRC as well as its own independent word clock with audio connections via co-axial plus dual PSUs as standard for extra peace mind when used in critical applications. As with the CDC MC MADI unit the co-axial ports glow either red or blue for Rx (receive) or Tx (transmit) – enabling fast and accurate configuring of the MegaCOMMS network especially in low light.
