The SR 4500 true diversity receiver provides maximum ease of use and the widest range of functions in its class. Its accurate battery life readout is a previously unavailable, invaluable advantage in live sound applications. A complete line of accessories makes the SR 4500 your first choice for every application. The transmitter uses a pilot tone to transmit battery status data to the receiver that displays the remaining battery capacity. The pilot tone decoder also allows the detection and display of other important information including the current position of the transmitter MUTE switch.

Auto Setup and Environment Scan functions automatically analyze the local RF environment, find usable frequency groups, and set frequencies. The optional HUB 4000 Q integrates the SR 4500 into a HiQnet™ system. With the PC control software System Architect™ setting up and monitoring highly complex systems is incredibly easy. A logic output allows remote control of external devices, e.g., an automatic microphone mixer. ´

Naturally, the SR 4500 operates in an extremely wide UHF band (30 MHz) and each frequency preset provides up to 19 intermodulation-free channels*. The maximum number of selectable frequencies is 1200. Using several frequency bands allows you to operate as many as 70 channels simultaneously. A large, backlit color display and a jog wheel make the SR 4500 easy to use and a programmable LED ring indicates important system parameters at a glance.

Housed in a half-rack, all-metal case, the SR 4500 is the most compact, reliable, and powerful UHF receiver in its price bracket. 

The HT 4500 is a professional handheld transmitter with a rugged body and connects to a choice of six different microphone elements to cover a wide range of applications.

Microphone elements include dynamic and condenser cardioid and hypercardioid models. The 30 MHz wide UHF band provides up to 1200* selectable frequencies, and several preset frequency banks for various countries help you set up a multichannel system very quickly. A backlit display makes it very easy to tune the HT 4500 to the same frequency as the SR 4500 receiver. A pilot tone system continuously sends transmitter status data including MUTE switch position and remaining battery life to the receiver.

Integrated charging contacts let you charge the optional BP 4000 battery pack without having to remove it from the transmitter. After only one hour, the battery pack will be fully charged and you can use the transmitter for 12 hours continuously.
