Operator Manual

The maximum count of any one type of connection is:

• 96-off input insert sends.

• 96-off input insert returns.

• 96-off input compressor external side chain connections.

• 96-off input noise gate external side chain connections.

• 96-off input direct outputs.

• 51-off mix bus insert sends.

• 51-off mix bus insert returns.

• 51-off mix bus direct inputs.

• 1-off talk mic input.

However, the XL8 can have much more than the standard connectivity by adding

DL451 I/O units. As there are nine AES50 connections

(fully redundant) available,

potentially, another 432 audio connections can be achieved (subject to other system

limits). This gives a maximum XLR count of 720. Figure 3 shows a system

configuration containing the extra nine DL451 I/O units, but does not show the

redundant duplicated network.

All connectivity is controlled via the GUI.

Surround capabilities

Theatres and broadcast have differing requirements for surround, and both are catered

for in the XL8.

Conventional stereo and SIS™ panning is assignable on a channel by channel basis

(channel one can be in stereo while channel two can be in SIS™), as follows:

• Stereo left–right routing to master buses.

• SIS™ left–right–centre routing to master buses.

Three additional surround modes operate as follows:

• Quad (left, right, LS and RS).

• Surround (left, right, centre, surround).

• 5.1 surround (left, right, centre, subwoofer, LS and RS).

Network

The XL8’s digital audio network utilises the physical connectivity of Ethernet

(EtherCon® connectors and Cat 5e/Cat6 cable), but replaces its data protocol with

AES50 protocol (implemented as SuperMAC) and the HyperMAC high capacity system,

which are more suited to high quality, low latency audio distribution. The use of the

AES standard allows straightforward interfacing with any third party hardware that also

utilises this connection.

AES50 and HyperMAC connections carry digital audio, control data and standard

Ethernet traffic bi-directionally down a single cable. Cat 5e cable is used for the ‘local’

(24-channel) connections and the single digital ‘snake’

— between control centre and

router — is either Cat 5e/Cat6 or fibre optic. The combination of audio, control, clock

and third party Ethernet data in a single network means that the hardware interfaces on

a single RJ45 connection.

1. These spare AES50 ports can also be used to directly connect any AES50 equipped units, such as a

hard disk recorder.

2. The digital snake is equivalent to a 384-channel analogue multi-core cable (192 channels in each

direction).
