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

 

 

=

one 4Ω speaker

 

=

one 8Ω speaker

 

16Ω

=

one 16Ω speaker

 

Two Speakers

 

 

=

4Ω + 4Ω

(wired in series)

=

8Ω 8Ω

(wired in parallel)

=

16Ω 16Ω (wired in parallel)

Four Speakers

 

 

=

(4Ω + 4Ω) (4Ω + 4Ω)

(wired in series/parallel)

=

(8Ω 8Ω) + (8Ω 8Ω)

(wired in series/parallel)

=

16Ω 16Ω 16Ω 16Ω (wired in parallel)

Six Speakers

 

 

=

(4Ω + 4Ω + 4Ω) (4Ω + 4Ω + 4Ω)

5.3Ω =

(8Ω 8Ω 8Ω) + (8Ω 8Ω 8Ω)

10.6Ω = (16Ω + 16Ω) (16Ω + 16Ω) (16Ω + 16Ω)

Eight Speakers

 

 

=

(4Ω 4Ω) + (4Ω 4Ω) + (4Ω 4Ω) + (4Ω 4Ω)

=

(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.

IRW-2PA specifications

Nady Systems IRW-2PA is a sophisticated wireless microphone system specifically designed for professional audio applications, featuring remarkable technology and user-friendly characteristics. This system offers a reliable solution for musicians, presenters, and audio professionals seeking high-quality sound without the constraints of traditional wired setups.

At the core of the IRW-2PA is its UHF (Ultra High Frequency) transmission technology, which ensures exceptional sound clarity and minimal interference. This frequency range provides a robust and stable transmission, making it suitable for live performances, corporate events, and educational environments. The system also offers multiple channels to avoid any possible signal conflicts, ensuring seamless operation in busy environments.

One of the standout features of the IRW-2PA is its dual-channel receiver, which allows users to connect two microphones simultaneously. This is especially beneficial for duets or interviews, where two speakers can be amplified without the need for multiple receivers. The receiver's backlit display provides clear visibility of essential information such as channel selection, signal strength, and battery life, allowing for quick adjustments even in low-light conditions.

The IRW-2PA includes a handheld microphone that is ergonomically designed for comfort and ease of use. The microphone features a cardioid pickup pattern, which effectively captures sound from the front while minimizing background noise, providing a professional sound that is crucial for live performances.

Another notable characteristic is the system's wide frequency response range, ensuring that it accurately reproduces vocals and instruments with clarity. This, combined with a high dynamic range, allows for effective handling of varied audio sources without distortion.

Battery life is another important aspect of the IRW-2PA. The system utilizes rechargeable batteries, which not only save costs over time but also ensure convenience for users who are frequently on the go. The system can operate for several hours on a single charge, making it an ideal choice for long events and performances.

Overall, the Nady Systems IRW-2PA stands out for its advanced technology, user-friendly features, and reliable performance. Its combination of dual-channel capability, ergonomic design, and robust UHF transmission makes it an excellent choice for professionals in need of a versatile and high-quality wireless microphone system. With its attention to detail and commitment to sound excellence, the IRW-2PA truly represents the pinnacle of modern audio technology.
