PRO2 Live Audio System
Owner’s Manual
Effects processing and GEQs
The PRO2 contains eight mono Klark Teknik (KT) GEQs and eight effects processors as
standard.
The effects processors (six maximum) can be freely chosen from the following:
•Stereo delay.
•Stereo flanger.
•Stereo phaser.
• Stereo harmoniser.
• Stereo reverb (KT DN780).
•Stereo Dynamic EQ.
• GEQ (each effect slot can be sacrificed to gain an additional four GEQ effects).
• Eight channels of SQ1 Dynamics.
Up to 28 mono KT GEQs can be patched into any output. There are many patching
options for the effects processors. They can be patched to any source or destination
within the system and you can even patch directly to and from an effect externally.
Surround capabilities
Theatres and broadcast have differing requirements for surround, and both are catered
for in the PRO2.
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, centre, right surround).
• 5.1 surround (left, centre, right, subwoofer (LCRS), LS and RS).
Network
The PRO2’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’
1
— 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.
All system connections are duplicated for full dual redundancy.
1. The digital snake is equivalent to a 384-channel analogue multi-core cable (192 channels in each
direction).
