XC Core and XD Core System 

The 52/XC Core is DHD's central processing unit 

for small or medium-sized mixing consoles with processing 

of up to 24 faders. It works just as well for 

small and medium-sized routers with a matrix size of 

2176 x 1856. The 52/XC Core occupies only half the 

width of a 19” 1 U rack slot. 

Rear View of 52/XC Core (52-7400) 

The 52/XD Core is our high-performance device for 

all routing and mixing tasks, fitting in only 1 U. 

With the support of up to four DSP modules, the 

52/XD Core is powerful enough to master the most 

demanding applications. 

The system can be used to process up to 64 faders 

or to set up an audio routing system with a matrix 

size of 8704 x 7424. 

Designed to Create Distributed Systems 

The 52/XC and 52/XD Cores and the 52/XC Concentrator 

provide common RJ45 ports for the 

connection of control modules and I/O boxes. Here, 

standard CAT cables are used, carrying A udio, 

Power and Control signals in the same cable – 

DHD's APC technology. 

Thus, your setup benefits from the advantages of 

common CAT cabling infrastructure which allows 

you to place I/O boxes and control modules anywhere 

you need them. 

All Gigabit Audio and data connections between 

Studio Machine Room 

52/XC I/O boxes 52/XC Concentrator 52/XC Core 

cores and concentrators are based on standard 

fibre-optic cables for gigabit Ethernet – DHD's GA 

technology. 

The 52/XC Concentrator is always dedicated to one 

core and acts as APC port extension unit. 

This design principle allows you to create true 

distributed installations, where every part of the 

system is where it should be. The use of standard 

data cables and structured cabling for the interconnection 

of DHD modules can dramatically reduce 

the overall system installation costs.

Rear View of 52/X D Core (52-74 4 0 /52-7450 ) 

The specialised rock-solid hardware of 52/XC and 

52/XD Cores consumes very little power. The combination 

with highly efficient external power supplies 

considerably reduces the operating costs of a DHD 

system compared to products of other manufacturers. 

To ensure that your audio network keeps running at 

all times, the 52/XC and 52/XD Cores provide extensive 

resilience features.

The Processing Engine 

The 52/XC and 52/XD Cores are the basis for all mixing 

console surfaces of the Series 52 product line. 

They power, for example, a small 4-fader 52/DX desktop 

mixer, a compact 8-fader 52/SX console, a medium - 

size d 16-fader 52/RX system or a large 32-fader 52/MX 

console. 

All 52/XC input and output modules and 52/ XC 

Concentrators are compatible with the 52/XC and 

52/XD Cores. You may also use I/O modules and cores 

of our 52/XS series. 

Used as routing matrix, the cores are not only able to 

switch audio signals, but can also fade those in and out 

and even apply DSP processing ( g ain, EQ or dynamics) 

to the signals. You may also create complex On-Air 

switching systems as well as talkback systems. 

For direct control, combine the 52/XC or 52/XD Cores 

with a great variety of DHD control modules, including 

faders, router control panels and TFT/touch displays. All 

control modules and TFT/touch displays use standard 

CAT cables for communication with the cores. 

DHD provides special PC software for remote control, 

routing, scheduling and monitoring. Third-party 

systems, too, can interface via GPIO or by using the 

open DHD External Control Protocol via Ethernet or a 

serial port. 

The flexibility of the 52/XC and 52/XD Cores is mainly 

based on the Toolbox5 configuration software. All your 

ideas and requirements for certain functions will be 

defined during a configuration process typically done 

by DHD or by your system integrator. This configuration 

is what makes your system work. However, if you need 

to change it later, just use the Toolbox5 software again. 

Studios use the 52/XD Core 

as central audio routing matrix. 

Any Series 52 control module 

can directly control the 

52/XC or 52/XD. 


Talkback 

52/XC I/O modules provide 

audio connectors and GPIO signals. 

DHD software uses Ethernet 

for configuration and 

control of the cores . 

Other systems can use 

Ethernet and GPIO to 

interface with the 52/X C .

Audio Networking 

DHD Audio Networking 

DHD cores provide high-quality digital audio networking using a 

unique ultra-low latency technology which needs only one audio 

sample for the synchronous data transmission of your digital audio 

signal. Simultaneously to the “MADI-like” audio data transmission, an 

IP-based transfer of control data packets takes place. 

This technology comes in two different versions: 

DHD GA and DHD APC. 

DHD GA “Gigabit Audio” uses standard gigabit Ethernet data transmission 

based on fibre-optic cables. This allows simultaneous transfer 

of 512 input channels and 512 output channels per port plus IP-based 

100 MBit/s control data packets. 

Use DHD GA for powerful core-to-core interlinks or for the connection 

of I/O boxes and control modules to the core via c oncentrators. 

DHD GA supports link lengths of up to 500 m using multi-mode fibreoptic 

cables or of up to 40 km using single-mode fibre-optic cables. 

DHD APC “Audio , Power & Control” uses standard Ethernet data 

transmission based on CAT cables. This allows the simultaneous transfer 

of 48 input channels and 48 output channels per port plus IP-based 

10 MBit/s control data packets. 

Use DHD APC for core-to-core interlinks or for the connection of I/O 

boxes and control modules. DHD APC supports link lengths of up to 

100 m using standard CAT cables. 

DHD APC will also provide the 48 V power required by end devices 

like I/O boxes or control modules.

Audinate Pty Ltd under U.S. patent number(s) 7747725, 8005939, 

7978696 and other patents issued, see www.audinate.com/patents. 

Dante is a trademark of Audinate Pty Ltd. 

IP Audio Networking 

Especially for the use with playout and radio automation software, 

DHD designed an IP audio interface to connect a PC directly to 

the console by using the PC's network card as sound card. 

This PC only needs the DHD XCIP driver to send 16 channels for 

playout and receive 16 channels for record. 

® 

The DHD XCIP driver (WDM for Windows 7) is included in the 

52-7140 XC DHD IP Audio Interface. 

The DHD 52/ XC Dante IP Audio Interface distributes the audio 

signals from the console to any other Dante-enabled DHD device, 

third-party device, PC or Mac. This allows monitoring, talkback 

and connection of remote facilities to the studio via the network. 

The audio network cloud might consist of: 

• DHD devices with 52-7180A XC Dante IP Audio Interface which 

connects up to 48 inputs and 48 outputs to the Dante IP network 

® 

• PC or MAC with Dante Virtual Soundcard for ASIO (Windows ) 

® 

or Core Audio (OS X ) based software which connects up to 

64 inputs and 64 outputs to the Dante IP network 

• Dante-enabled devices from other manufacturers connected to 

the Dante IP network
