796-20
SIX ZONE CONNECTING BLOCK/EXPANDER
The Model 796-20 is a Six Zone Connecting Block that allows IR control of elaborate multizone audio/video
systems. It serves as an expansion module for the 795-20 or, by itself, as a six zone block. Expansion
beyond 6 zones can be achieved with multiple 796's, limited only by IR noise considerations. The zone
input terminals permit the connection of any Xantech IR Receiver, Keypad or controller device. Each zone
output can control 2 or more pieces of equipment per zone, independent of the other zones, via single or
dual emitters or be direct wired to the IR input of Xantech Preamps, etc. The common output port can drive
1 single or 1 dual emitter or the IR input of Xantech Connecting Blocks for control of common source
equipment from any zone. The 796-20 utilizes active isolation devices for elimination of internal zone-to-
zone cross-talk as well as high speed amplification to all output ports for operation with a wide range of
IR controlled products.
SPECIFICATIONS
• Zone IR Inputs: Six 3-screw terminal connectors to interface with all Xantech 3-lead IR receivers and/or
keypads.
• Outputs: 12 Zone emitter ports (3.5mm mini mono jacks) and 1 common port (screw terminals).
• Green LED test indicators are connected in series with the zone outputs. They will only light when the
connected emitter or device is conducting current.
• Zone output ports A and B and the common port are parallel driven and have a 470-Ohm resistor in series
with each port for lower power operation. This prevents overload of IR sensors on A/V components and
also allows the use of models 282, 283, 284 & 286 series Mini Emitters, Xantech Controllers, Preamps,
etc. in any combination.
• Power requirements: 12 volts DC. Use 781RG or 782-00 Power Supplies.
• Power is applied via the
+12 & G
of the common terminals (see
Figs. 2-4
).
• Dimensions: 13-3/8" W x 1-7/8" D x 1" H
INSTALLATION
Fig. 2
, illustrates a typical installation using the 796-20 in a six zone system. A variety of Xantech IR
Receivers and a keypad are shown in the various zones. When configuring a system, please keep the
following items in mind:
1. Additional IR Receivers may be wired in parallel at each zone input, if desired, up to a total of twelve.
More than twelve is not recommended, even in a zoned system, because stray IR noise picked up by
the many IR receivers may cause erratic operation and reduce remote control range.
