1.11 MD24 MULTI DISTRO PANEL
Figure 33: MD24 Multi Distro Panel
As seen in the system block diagram of Figure 6, the MD24 Multi Distro panel is used onstage for
distribution of MC28100 MULTI return snake lines that originate from the CO24 Control Output
panel located at FOH. The MD24 panel can be packaged separately and located either stage left or
right (depending on physical constraints regarding snake runs) or, alternatively, can be mounted in the
amplifier rack that is first in line for patching purposes.
A DOM2 AMP LINK cable is run from the Multi Distro panel to the appropriate 19 pin CA-COM
connector of the first amplifier, e.g., B lines for FOH left if the amplifier rack is located stage right.
AMP LINK cables are then used to connect subsequent stage right amplifiers so that all receive B lines
(including subwoofer and 2-way amplifier racks which are configured using SUB and 2-WAY COMB
connectors, respectively). A CROSS LINK cable is then used to distribute C lines for FOH right from
the MD24 Multi Distro panel cross stage to the stage left amplifiers. These racks are connected in the
same way using AMP LINK cables and similar connections are performed for the A and D lines to
accommodate Left-Left and Right-Right arrays, as necessary. Separating signal distribution lines to
individual L-L, L, R and R-R arrays is also an effective way to avoid potential ground loop problems.
1.12 CO6 CONTROL OUTPUT PANEL
The CO6 Control Output panel is a scaled down 6 channel version of the 24 channel CO24 panel that
is suitable for 2-way or 3-way stereo FOH or fill / delay system applications. CO6 is intended for use
with a 2 in x 6 out (or 3 x 6) Digital Signal Processor (DSP) for the creation of a compact, modular
drive rack or for standalone master amplifier rack packaging. DSP outputs are connected to the 6x
female XLR patch bay on the rear side of the CO6 panel and these outputs are in turn assigned to the
front panel 19-pin CACOM connector. This provides a 6 channel multicore return snake system when
used with a standard 30 metre DOM30 (Cross Link) cable. For longer cable runs, multiple DOM30
cables can be extended using the DOMP adapter (19-pin male-male CACOM adapter).
The CO6 Control Output panel allows for maximum flexibility while providing a scaleable architecture
that can be used for small, medium and even large system applications since it is compatible with the
dV-DOSC and V-DOSC signal distribution strategy and cabling/connector standards.
