IRC-2.0 & IRC-2.1
Surface Mount Mini Infrared Receivers
SmartPath
™
INSTALLATION INSTRUCTIONS
The IRC-2.0 and IRC-2.1 are very small IR Receivers designed to be mounted on
flat surfaces in furniture recesses, under shelves, etc., using the double-sided tape
supplied. Among their unique features is an exclusive Ambient Noise Suppression
(ANS) system. It acts to push down IRI, CFL, EMI, or ESI noise sources so that
stronger signals from IR remotes have adequate margin for command of the
controlled component.
Note: The ANS will take a few seconds to adjust to a given noise source. During this
time, the blue Activity LED will glow brightly and then fade out. If the interference
disappears momentarily, then returns, the fade down process will repeat. Certain
noise sources, however, (such as Plasma Screens) may result in low-level flickering
even after the fade down. This is normal. Such signals have been acted upon by
the ANS, allowing most equipment to be controlled.

FEATURES/SPECIFICATIONS
• The IRC-2.0 and IRC-2.1 are identical except for lead termination. (See Fig. 1)
The IRC-2.0 has a unique 3.5mm quad plug to accommodate STATUS as well as
IR, Power and Gnd connections. The IRC-2.1 comes with stripped ends plus a
4-conductor terminal strip allowing interface connections to in-wall room-to-room
wiring.
• Exclusive Ambient Noise Suppressor (ANS) system.
• STATUS Indicator: Green LED for System On/Off indication.
• ACTIVITY Indicator: Blue LED indicates IR signal activity in a completed circuit with
a Terminator or an Emitter.

• Requires Power Supply, Terminator Block and Emitters for IR Repeater operation.
• Mounting: Attaches to any flat surface using the included double-sided tape. The tape may
be applied to the back, top, or bottom surfaces of the IRC-2.0 / IRC-2.1 to accommodate
the installation.
• Power: 12V DC @ 6 mA. Supplied from connected Terminator.
• IR Lens rejects visible light interference.
• Crosshatch Shield (internal) inhibits EMI/ESI Interference.
• Carrier Frequency Acceptance Range: 28 to 90 kHz.
• Control Range: Up to 35 feet, depending on remote strength and ambient noise conditions.
• Control Angle: ±50˚ off axis.
• Room-to-Room Wire Recommendations: Use 4-conductor (min.) 24 gauge unshielded
solid or stranded copper wire up to 1200' (Cat. 5e ok), 22 gauge up to 2000', 20 gauge
up to 3000' and 18 gauge up to 5300'.
• Maximum recommended cable length: 5300' with 18 gauge.
• Dimensions: 29⁄16" (65mm) L x 9⁄16" (14mm) W x 1⁄2" (13mm) D.
SYSTEM CONNECTIONS
The following are a few typical applications of the IRC-2.0 and IRC-2.1 for IR repeater systems.
A Basic System
Fig. 2 shows a basic plug-and-play installation, such as controlling components that are
behind closed cabinet doors or in a closet.

1. Mount the IRC-2.0 in a recessed cabinet area or under a shelf, using the two-sided
adhesive tape supplied.
2. Plug the IR Receiver and Emitters into the SpeakerCraft AT-1.0 Amplified Terminator, as
shown.
3. Set the DIP switches on the AT-1.0 to EM ON and NET ON or OFF.
4. Plug in the Power Supply.
5. The remote control, fired at the IRC-2.0, should now control the components.

A Multi-Room System
Fig. 3 is an example of the IRC-2.1 wired IR Receiver in a multi-room system with other
SpeakerCraft IR receivers in various rooms, plus a local IRC-2.0. These control the various
components in the main room or equipment area.

1. Pull 4-conductor wire from each room (home runs) to the AT-1.0 Terminator near the
controlled components.
Note: Use 24 gauge unshielded solid or stranded copper wire up to 1200' (Cat. 5e
ok), 22 gauge up to 2000', 20 gauge up to 3000' and 18 gauge up to 5300'. Total
lengths include all wire runs from each room added together, not just the longest
single run. If using shielded wire, these lengths would be reduced by approximately
30%. Also, to achieve operation with long lengths, the lower DIP switch on the
AT-1.0 must be set to the NET ON position.
2. Connect IR receivers in each room to the 4-conductor home runs as shown, using the
4-conductor terminal strip supplied.
3. Connect the home run wires to the correct terminals on the AT-1.0 EZ-Connect Terminals.
Note: You may use the SpeakerCraft CB Connecting Block (not illustrated, stock #
ASM20200) to help connect the many paralleled home run wires to the AT-1.0
EZ-Connect Terminals.
4. Install and plug the various emitters into the AT-1.0.
5. Set the DIP switches to EM ON (or BL ON if using Blasters behind closet doors) and
NET ON.
6. Plug the local IRC-2.0 IR Receiver into the IR RCVR jack.
7. Plug in the PS-1.0 12V DC Power Supply.
8. A remote control, fired at the IR receivers, should now control the components.
Note: Refer to the SpeakerCraft AT-1.0 Instructions for Power Supply considerations.
STATUS Brightness
Fig. 3 also shows how an external resistor can be added to reduce the brightness of the
Status LED’s on SpeakerCraft IR Receivers to any desired level.
In this example, a PS-1.0 12V DC Power Supply is used as the voltage source to indicate
ON/OFF status of an A/V Receiver.
Choose a resistor value that achieves the brightness you desire (about 2.2k to 12k, 1/8 W).
Connect it in series with the STATUS lead on each IR receiver desired, as shown.
