The Model VCIR-CFL is an impedance match-
ing stereo speaker volume control combined
with a "CFL Friendly" IR Receiver. It mounts in
a single gang J-box. The volume control sec-
tion has the same impedance matching capa-
bilities as that of the Xantech Model 760-00
Match Maker volume control. The IR Receiver
section has similar performance to that of the
480-80 CFL Dinky Link IR Receiver with the
added feature of a STATUS LED for system
ON/OFF indication.
CAUTION:
The VCIR-CFL is designed to
control products that operate with 36 to 42
kHz IR Carriers only!
NOTE
: The volume control section of the
VCIR-CFL is manually controlled only.
The IR
Receiver section is for control of other system components -- it cannot control the volume control
section!
SPECIFICATIONS – VOLUME CONTROL SECTION
• Type
: 2 channel TRI-FI™ wound precision autoformers, with independent gnds.
• Terminals
: Plug-in type screw terminals.
• Power Rating
: 25 Watts continuous, 150 Watts peak.
• Freq. Response
: 20-20,000 Hz
±
1dB at 1 watt.
• Attenuation
: 11 steps at 3 to 6 dB per step - 35 dB max. (Max. CCW is OFF).
S1 setting: 0 dB @ Max. CW (pass-through position).
S4 setting: 9 dB @ Max. CW.
S8 setting: 13 dB @ Max. CW.
• Impedance
: S1 setting: Pass-through position. i.e. 8 Ohms on OUTPUT reflects 8 Ohms to INPUT (Max.
CW position).
S4 setting: 8 Ohms on OUTPUT reflects 32 Ohms to INPUT . Likewise, 4 Ohms on OUTPUT reflects 16
Ohms to INPUT (Max. CW position).
S8 setting: 8 Ohms on OUTPUT reflects 64 Ohms to INPUT. Likewise, 4 Ohms on OUTPUT reflects 32
Ohms to INPUT (Max. CW position).
• Mounting
: Fits most new construction junction boxes - uses single space.
NOTE: It may be necessary to cut off the back portion of a J-box or use a "P" ring to have sufficient room.
Be sure to check fit before choosing J-boxes!
• Dimensions
: 1-5/8" (41.3mm) W x 2-7/8" (73mm) H x 2-7/16" (62mm) D
