6.Instrument Use

Secure the connection from the GT CABLE (30) by turning the slip ring on the plug into the transmitter clockwise to thread it on the jack. To unplug, reverse the process. Plug the 1/4” phone plug into the instrument. When ready to play, slide the audio MUTE SWITCH (26) to “ON” position Adjust the volume of the receiver as per the Audio Output Instrument Connection section of the above UHF-4 receiver instruction. (Note: The INPUT LEVEL CONTROL (28) is deactivated and not used when the UB-4 is in INSTRUMENT mode. Levels should be adjusted with the volume control of your instrument.)

(Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or connections are used with any wireless system. Therefore, the supplied INSTRUMENT CORD (30) has a factory installed capacitor inside the 1/4" plug. This capacitor provides first order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still give you scratchy noises, we suggest these steps to eliminate them:

1)Make sure all guitar volume and tone pots are clean and all contacts are solid–this is very important.

2)A 47pf capacitor soldered across the hot to ground terminals of the guitar’s volume and tone pots will provide extra filtering.)

7.Microphone Use (with either a lavalier or headworn microphone)

Secure the connection from the LAVALIER (32) or HEADWORN MIC CORD (31) by turning the slip ring on the plug into the transmitter clockwise to thread it on to the jack. To unplug, reverse the process. To use the lavalier mic, attach it at chest level. Do not place it too close to the mouth–a distance of about six inches usually works best. To use the headworn mic, place it on the head and adjust the boom so that the mic is about one inch to the side of the front of the mouth. As the microphone cord also serves as the antenna, be sure to extend it fully. Rolling up or shortening the cord may reduce the effective operating range–keep it as straight as possible. When ready to speak, slide the OFF/STANDBY/ON SWITCH (26) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above UHF-4 receiver instruction. [Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling and screeching) will be avoided. Please also note the pickup pattern characteristics of the microphone selected. Omnidirectional mics pick up sound equally from all directions, and are prone to feedback if not used carefully. Unidirectional mics are more resistant to feedback, but pick up sound sources best that are directly in front of the mic. Also, mics that are farther from the sound source, such as lavaliers, require more acoustic gain and thus are also more prone to feedback than close-source mics such as handheld or headworn models that are used close to the mouth].

For optimum performance, an INPUT LEVEL CONTROL (28) is provided. Adjust the gain by turning the control with a small screw driver. For lavalier mic use, it is recommended that the level be set at about 1/2 maximum. For headworn mic use, it may be advisable to turn the gain down somewhat, depending on the volume levels expected. In either application, experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and is not recommended.)

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.

These systems utilize UHF (Ultra High Frequency) technology, which provides numerous advantages over traditional VHF systems. 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.
