CAMCO USER MANUAL
VORTEX POWER AMP SERIES
P.21
5.1 E.U.I. (Extended User Interface)
The E.U.I. slot contains the Rear XLR Panel and the Input Signal Parallel switch
as standard. Other input cards are available (See 5.1.3 Accessories) Always switch
off and unplug the VORTEX from mains, when working on the E.U.I.
The switches described below are not readily accessible and cannot be
checked visually from the outside. To remove the E.U.I. unscrew the two Phillips
head screws at the left and right end of XLR-Panel and carefully slide out the
E.U.I. To ret the E.U.I into the VORTEX, carefully insert the PCB in the guide-rail
(left/right) and slide it in.
Don’t forget to replace the screws!
5.1.1 Input Signal Parallel Switch
If you want to hard-wire the XLR input connectors together on the E.U.I., just
change from Stereo to Mono using switch S1. Be careful when you do this!
(See section 3.7, Input Signal Chaining)
5.1.2 Filter On / Off Switch
If a lter is present on the E.U.I. this can be activated or bypassed using switch
S2.
5.1.3 Accessories
Different types of lters are available. For further information contact your
dealer or CAMCO
5.1.4 What Are The Possibilities Using The E.U.I.?
The E.U.I. is a very powerful interface, which allows access to most of the system
parameters. For example: volume, input signal, mute, output current, clip signal,
temperature and more. It makes it possible to utilise lters, remote control,
signal processing, and more… Please contact your dealer or CAMCO to
customise the E.U.I. according your wishes.
5.2 C.A.I. (Camco Audio Interface)
5.2.1 Camco Audio Interface
C.A.I. is a bus system, in which all signicant device functions can be monitored
externally and remotely controlled using a master PC. Up to 99 devices can be
controlled in parallel in each phase of the bus system, which simply consists
of a two-core insulated cable. The master can serve several phases for larger
applications. For more information, please contact your dealer or distributor.
5.2.2 Wiring
To connect the VORTEX to your C.A.I. - system use a fully-wired telephone-type
cable with RJ12 connectors. For longer distances use high grade cable like
for RS485, DMX512 for AES/EBU digital audio. You can chain several VORTEX
ampliers using the second C.A.I. Connector on each amplier. A linear net-
work topology is recommend with 100 Ohm termination at its end. Please refer
to RS 485 specications.
5.2.3 C.A.I. Address Settings
The C.A.I. address selection procedure will not affect the operation of the
VORTEX but whilst this procedure is active, the Volume cannot be adjusted by
using the Pots.
