1. Operation
The IR Sensors act as “antenna” for your infrared wireless microphone system. A multiple array of wide angle IR-sensitive LED’s in each sensor receives the infra- red signal emitted by your IR transmitter. The Sensor Power LED (2) will light to indicate the sensor is properly connected to the IRW-2PA when powered on. The Channel A and B IR LED indicators, located on the front panel of the IRW-2PA, will light green when an infrared signal on the corresponding channel is detected. These sensors should be positioned for maximum range and mobility of the wireless microphone user.
2. Additional Sensors
To increase mobility and maximum range, additional sensors can be either plugged into the remaining Infrared Sensor Inputs (1) or daisy-chained with existing sen- sors using the optional IRW-SY Multiple Sensor Y-adapter.
3. Wall Mounting
The IRW-1S sensors can be mounted on walls using any of the Wall Mounts (3) included. See the Installation section on pg 6 of this manual for information re sen- sor positioning.
INSTALLATION
3.Connections:
a. Connect the IRW-1S IR Sensors to the IRW-2PA receiver by plugging the sensor coaxial extension cable plugs into the Infrared Sensor Inputs (1). Each sensor input will receive both channels A and B signals. To increase mobility and maximum range, additional sensors can be added by plugging into the two remaining inputs, or by daisy-chaining sensors. To daisy-chain sensors, disconnect the sensor from the coaxial extension cable and use the optional IRW-SY Multiple Sensor Y-adapter to reconnect the original sensor as well as the additional sensor/extension cable.
b. Connect the speakers to the Speaker Output (2) spring clip connector using speaker cable (not included). The power amp can handle loads of 4Ω impedance or greater. When using multiple speakers, care must be taken to ensure that the total impedance is not less than 4Ω and that all speakers are in phase with each other. Following are some speaker combinations that the amplifier can handle.
One Speaker | | |
4Ω | = | one 4Ω speaker | |
8Ω | = | one 8Ω speaker | |
16Ω | = | one 16Ω speaker | |
Two Speakers | | |
8Ω | = | 4Ω + 4Ω | (wired in series) |
4Ω | = | 8Ω 8Ω | (wired in parallel) |
8Ω | = | 16Ω 16Ω (wired in parallel) |
Four Speakers | | |
4Ω | = | (4Ω + 4Ω) (4Ω + 4Ω) | (wired in series/parallel) |
8Ω | = | (8Ω 8Ω) + (8Ω 8Ω) | (wired in series/parallel) |
4Ω | = | 16Ω 16Ω 16Ω 16Ω (wired in parallel) |
Six Speakers | | |
6Ω | = | (4Ω + 4Ω + 4Ω) (4Ω + 4Ω + 4Ω) |
5.3Ω = | (8Ω 8Ω 8Ω) + (8Ω 8Ω 8Ω) |
10.6Ω = (16Ω + 16Ω) (16Ω + 16Ω) (16Ω + 16Ω) |
Eight Speakers | | |
8Ω | = | (4Ω 4Ω) + (4Ω 4Ω) + (4Ω 4Ω) + (4Ω 4Ω) |
4Ω | = | (8Ω 8Ω 8Ω 8Ω) + (8Ω 8Ω 8Ω 8Ω) |
8Ω | = | (16Ω 16Ω 16Ω 16Ω) + (16Ω 16Ω 16Ω 16Ω) |
c. Connect the AC/AC power supply to the side panel 3-prong AC Power Input (3) and connect the other end to an AC outlet.
d. If desired, connect an auxiliary device to the IRW-2PA using the Aux Input (4) 1⁄4” jack. This input is designed to accept line level inputs from CD players, MP-3 players, and tape decks. Use a stereo-to-mono adapter cable so that the right signal is not lost from the stereo mix. If the audio level is too low, try using the Mic Input. e. If desired, connect a microphone to the Mic Input (5) 1⁄4” jack. This input is designed to accept mic level to low line level signals.
