RCS Audio-Systems UBR-016 UHF receiver for Sound-Guide system 863–865 MHz with leather bag content_copy

The UBR-016 is a UHF receiver from RCS Audio-Systems, specifically designed for use in personnel guidance systems. It serves as a receiving device for sound guide systems, where a central transmitter unit (e.g. UBT-016) transmits audio signals to multiple receivers. The receiver enables wireless transmission of voice and audio signals with a range of 50 to 80 meters, making it suitable for guided tours in museums, exhibitions, or events. Signal transmission occurs in the frequency range of 863 to 865 MHz, with 16 different frequencies available to minimize interference. The transmission technology is based on PLL-synthesized modulation, ensuring stable and interference-free transmission.

Applications

The UBR-016 is primarily intended for mobile applications in tour and guidance technology. It is used in combination with a transmitter (e.g. UBT-016) to enable group tours without acoustic interference from other groups or ambient noise. The range of 50 to 80 meters is sufficient to cover large rooms or outdoor areas, although the actual range depends on the environment, such as walls or metallic structures. Typical use cases include museums, exhibitions, conferences, or cultural events.

Functions and Equipment in Detail

The receiver features an audio frequency range of 50 Hz to 15 kHz ±3 dB, enabling clear and natural reproduction of speech and music. The signal-to-noise ratio is 80 dB, ensuring high sound quality and low background noise. The output is configured as LINE, allowing direct connection to headphones with a 3.5 mm jack. The maximum modulation bandwidth (Max. Deviation) is ±40 kHz, ensuring robust and distortion-free transmission. Power supply is provided by two AAA micro-batteries (1.5 V) or rechargeable NiMH batteries specifically developed for the UBR-016 and UBT-016 models.

Technology Explained Simply

The PLL-synthesized transmission technology ensures that the receiver is precisely tuned to the transmitter's frequency, minimizing interference from other devices or frequency drift. The frequency band of 863 to 865 MHz is located in the UHF range, offering good wall penetration and low sensitivity to electromagnetic interference. The 16 available frequencies allow flexible use in environments with multiple simultaneous tours, preventing signal overlap. The output via a 3.5 mm jack is universal and compatible with most headphones designed for sound guide systems.

Compatibility and Accessories

The UBR-016 is part of a personnel guidance system and operates with the UBT-016 transmitter. Accessories include headphones for sound guide systems, which can be directly connected to the 3.5 mm output. The use of NiMH batteries in AAA format is possible, with the battery set specifically developed for UBR-016 and UBT-016. The batteries are rechargeable, free from memory effect, and can be charged using standard NiMH chargers.

Mounting and Installation

The receiver is compact and portable, with dimensions of 60 x 85 x 19 mm. It can be easily placed in a pocket or attached to a belt, with a leather pouch included in the delivery scope to protect the device from mechanical damage. Installation involves inserting the batteries or rechargeable batteries into the integrated battery compartment and connecting the headphones to the 3.5 mm jack. Operation is controlled via a simple on/off switch located on the front of the device.

Advantages in Operation

The UBR-016 provides reliable and interference-free transmission of audio signals over a range of up to 80 meters. The high signal quality, with a signal-to-noise ratio of 80 dB and a frequency range of 50 Hz to 15 kHz, ensures clear voice reproduction. The use of rechargeable NiMH batteries reduces operational effort and costs during continuous use. Combined with a transmitter such as the UBT-016, it enables professional tour technology that has proven effective in cultural and tourism facilities. The included leather pouch protects the device and facilitates transportation.
