INSTALLATION
The IR receiver leads for the VCIR-CFL are connected in the same way as for any of the other Xantech IR
Receivers. The only exceptions are to identify the leads on the ribbon cable correctly and the use of the
Status LED Indicator. Typical connections are shown in
Figs. 3. and
4
.
Fig. 3
shows connections to a connecting block in a simple single zone system. A 786-00 Power Supply
provides 12 VDC to drive the Status LED in the VCIR-CFL to indicate the ON/OFF condition of the system
A/V receiver.
You may reduce the brightness
of the Status LED by placing a resistor in series with the STATUS lead.
Use a resistor value that achieves the desired brightness level (usually 1k to 10k Ohms, 1/8 watt).
Fig. 4
illustrates connection of 2 or more VCIR-CFL's to a ZPR68-10 in a multi-zone system. Here, the
STATUS terminal on the zone drives the Status LED in the VCIR-CFL's to have a visible zone ON/OFF
indicator in the remote rooms.
The terminal marked STATUS on the ZPR68-10 connects to the Status leads on the VCIR-CFL's (in series
with a resister, if desired) as part of the normal 4-wire hookup.
Connect additional VCIR-CFL's (if any) in the same manner as shown.
Connect the speaker volume control sections as shown in
Fig. 5
. Four-conductor speaker wire (two wires
for each channel) is connected from each of the VCIR's to the power amplifier (home run from each room).
Also, each channel (left and right) requires a pair of wires from the VCIR-CFL to the speakers. The plug-
in connectors and the printed circuit board of the VCIR-CFL are marked with the terminal identifications.
CAUTION:
Be sure
the amplifier or re-
ceiver speaker ter-
minals are con-
nected to the INPUT
terminals on the
VCIR-CFL and the
speakers are con-
nected to the OUT-
PUT terminals on
the VCIR-CFL as
shown in Fig. 5!
The negative right input wire (
INPUT R–
) and the negative right output wire (
OUTPUT R–
) are connected
together in the VCIR-CFL. Likewise,
INPUT L–
and
OUTPUT L–
are connected together. There are no
common ground connections between the left and right channels in the VCIR-CFL, allowing bridged type
amplifiers to be used, if desired.
NOTE:
Since the VCIR-CFL and the 760-00 volume control sections are identical, you can intermix them
in the same system as shown in
Fig. 5
. Simply use the 760-00's in rooms where you do not need IR control.
MOUNTING
The VCIR-CFL is intended to be wall-mounted in an electrical junction box and trimmed with a decorator-
style plate (not included). Observe the following:
1. Even though the VCIR-CFL has high rejection of IR Interference from High Frequency Ballasted
Overhead or Compact Fluorescents and direct or reflected sunlight, you should choose a wall location
away from strong locations of such interference as they will have the effect of reducing the range of
satisfactory operation.
