UHF-4 Receiver

1. Rackmounting the Receiver

There are 2 options available for rackmounting the UHF-4 receiver: singly or side-by- side with another UHF-4 Series receiver.

a.Single mounting: Remove the receiver SIDE MOUNT CLIP (1) from each side of the receiver (as shown) and slide in the optional ERM-3 RACK EARS (2).

b.Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (1) from both UHF-4 receivers, join the two receivers with the EJC-3 JOINING CLIP

(3)and attach the ERM-33 RACK EARS (4) as shown. (Note: Do not mount

the receiver in a rack directly above an amplifier or other source of high heat – this could degrade the performance of the UHF-4. Always ensure adequate airflow and heat dissipation in any rack configuration.)

2. Powering the Receiver

Plug the 15V/0.3A AC/DC ADAPTER (5) provided into the DC INPUT JACK (9) on the back of the receiver. Then plug the power supply into an AC outlet. Press the POWER SWITCH (11) once to turn on the receiver. The POWER ON LED (12) will now light and the receiver is operational.

3. Antennas

The UHF-4 receiver is supplied with FOLDING ANTENNAS (15). These should be extended fully to obtain maximum range. Optimal antenna position is 45 degrees from the receiver (at 90 degrees from each other). For maximum range, it is always best to maintain a line of sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible.

4. Mute (Squelch) Adjustment

In normal operation, the SQUELCH CONTROL (6) should be set fully clockwise to the factory preset RF level (Max. Sens.). However, in areas of high RF activity, the squelch (or mute, as it is sometimes called) may need to be adjusted to compensate for the adverse conditions in a particular location. If, with the transmitter off, the receiver’s A and/or B DIVERSITY LED INDICATORS (13) flicker or stay on, the squelch control should be turned counterclockwise until the A and/or B LEDs extinguish. When the squelch is properly adjusted, the A or B LEDs will only light when the transmitter is turned on. Turning the squelch control too far counterclockwise will reduce the range, but yield a quieter squelch (mute) function. During operation, especially at ranges greater than 75 feet, one or the other of the A or B LEDs may alternate briefly. This is normal–the unit’s DigiTRU Diversity™ reception ensures that the received audio will not be interrupted. When both LEDs extinguish, the transmitter is out of range for that given location, and the user should move closer to the receiver to re-establish the radio link.

UHF4LTSYS11, UHF4HTSYS16, UHF4HTSYS11, UHF4HTSYS14, UHF4LTSYS14 specifications

Nady Systems has established itself as a pioneer in the wireless audio technology industry, offering a diverse range of products that cater to musicians, audio professionals, and performers. Among their offerings, the Nady UHF Wireless Microphone Systems stand out, particularly the models UHF4LTSYS13, UHF4HTSYS15, UHF4HTSYS13, UHF4LTSYS16, and UHF4HTCH11.

One of the primary benefits of UHF technology is the ability to operate on a wider range of frequencies, reducing the likelihood of interference and ensuring clearer audio transmission. This makes them suitable for a variety of applications, from live performances to studio recordings.

The UHF4LTSYS13 is designed for those who prefer a lavalier microphone solution. It features a lightweight and compact design, providing ease of use without sacrificing sound quality. The system operates on UHF frequencies, ensuring it captures clear audio signals even in challenging environments.

Conversely, the UHF4HTSYS15 and UHF4HTSYS13 are handheld microphone systems ideal for vocalists and presenters. These models come with dynamic handheld microphones that are engineered to deliver powerful, rich sound, making them perfect for live performances. The UHF4HTSYS15 features enhanced frequency response and transmission characteristics, allowing for optimal audio fidelity.

The UHF4LTSYS16 offers similar benefits to the UHF4LTSYS13 but boasts additional features such as extended battery life and improved range. This makes it particularly suited for long events where reliability is critical.

Lastly, the UHF4HTCH11 model is tailored for situations demanding flexibility and adaptability. It supports interchangeable microphone capsules, giving users the freedom to customize their microphone according to their specific needs.

All models feature an auto-scan function for easy setup, ensuring users can quickly find and switch to a clear frequency, minimizing disruptions. Additionally, they come equipped with a robust receiver that provides a stable signal and exceptional audio quality.

In summary, Nady Systems’ UHF4 series represents the company's commitment to quality and reliability in wireless audio transmission. With a range of options suited for various applications, these systems are an excellent choice for anyone looking to enhance their audio experience.
