Introduction

Thank you for selecting the Azden "RED" infrared system as your wireless solution. We are confident that it will perform beyond your expectations. For over 40 years Azden Corporation has been creating technologically advanced products. By taking advantage of the latest in CAD design and SMT production techniques, Azden's engineers are able to produce products that exceed the published specifications and perform well beyond the warranty period.

Azden "RED" represents a breakthrough in wireless. Instead of the normal radio waves that other wireless systems use, Azden "RED" uses invisible light beams in the infrared range.

Through the use of infrared you will no longer be plagued by outside interference. "RED's" enhanced performance assures you of the finest in audio clarity and reliability. The specially selected high-frequencies provide you with trouble free performance, even in fluorescently lit rooms. Like all infrared, Azden "RED" will not operate correctly outside in the sunlight.

In the real world, the ability to use multiple systems in the same location without frequency interference will prove to be a tremendous benefit to you. Using infrared means that the audio generated in your room stays in your room. Your discussions cannot be overheard on other systems in other rooms.

Designed by professionals - for professionals, Azden "RED" will provide you with years of worry-free, high-quality performance.

Troubleshooting

The single most important thing to ALWAYS check when trouble arises is the battery. Make sure they are fresh and the POWER LED is glowing brightly.

SYMPTOM CAUSE

No POWER LED

a. Receiver switch Is set to "OFF"- change to "ON"

b. External 12V DC power source is not connected or is malfunctioning c. Dead or very weak battery in body-pack or handheld

No audio from body-pack

a. Make sure the volume on the receiver is turned up for the appropriate channel and the body- pack is powered ON

b. If two body-packs are being used, make sure they are set to different frequency channels

c. If using an external mic, make sure it is plugged in to the body-pack properly and the internal gain control has been adjusted.

No audio from handheld mic

a. Make sure the volume on the receiver is turned up for the appropriate channel and the handheld mic is powered ON

b. If two handheld mics are being used, make sure they are set to different frequency channels

Intermittent audio

a. Make sure there is a clear path between the emitter and the receiving sensor. Best results are obtained when the receiving sensors are mounted high - above everyone• fs head Limited working range a. Install extra external sensors

b. If using a body-pack, set the Power Mode to Hi.

c. Make sure all emitting points on the transmitters are covered by hands, towel etc. Move them and face the emitting point to the receiver direction.

d. Make sure all emitting points on the transmitters are wet. Make clean with dry towel. e. Make sure direct sun light or any strong light is coming into the sensor.

Be careful the mounting position of external sensor or the facing direction of internal sensor.

Infrared transmission operates via light waves rather than radio frequencies, which can often be susceptible to interference from various electronic devices. This makes the IRH15C an excellent choice for environments with heavy RF traffic, ensuring clear and uninterrupted audio signals. Because the infrared signals cannot penetrate solid objects, the device works best in line-of-sight situations, making it particularly effective for indoor settings.

The IRH15C receiver operates on a frequency range of 2.3 MHz, which is regulated and protected for optimal performance. It is capable of receiving audio from multiple IR transmitters, allowing for flexibility in various applications, especially when multiple speakers are involved. This device can operate in conjunction with the Azden IRH2 infrared transmitter, creating a comprehensive system that delivers superior audio quality.

In terms of design and usability, the Azden IRH15C is compact and lightweight, making it easy to transport and set up for various applications. It features a simple interface, enabling users to quickly connect it with audio equipment and start using it with minimal setup time. This system also includes a built-in rechargeable battery, allowing for extended use without the need for frequent replacements.

The sound quality produced by the Azden IRH15C is rich and clear, which is essential for any professional audio environment. With a low signal-to-noise ratio and excellent frequency response, users can expect high fidelity audio that meets industry standards.

In summary, the Azden IRH15C infrared receiver stands out for its reliability, ease of use, and exceptional audio quality. Its infrared technology minimizes interference, making it a solid choice for professional audio applications. With features tailored for flexibility and performance, the Azden IRH15C is a valuable tool for any audio or video production. Whether you are a sound engineer, a videographer, or a performer, this device is designed to enhance your audio experience and ensure consistent performance.
