WMS 4500

• Complete wireless networkable solution for touring and installations.
• Maximum performance in an ultra-compact design.
• Integration into a HiQnet® system with optional HUB 4000 Q

The WMS 4500 is the Wireless System for the professional use. It is based on the market feedback of its successful predecessor WMS 4000.

The result is not only even more robust system, it also includes a number of useful features including an advanced backlit display on the transmitters and the receiver, remaining battery life readout, silent mode, pilot tone status data transmission, environment scan and rehearsal functions, auto setup frequency search, and many other functions that make the WMS 4500 extremely user-friendly.

Interesting detail: The charging unit CU 4000 reduced the operation cost almost to null, additionally it helps the environment to reduce the waste on batteries. The charging unit comprises two loading slots, so it is possible to recharge either two transmitters (HT 4500, PT 4500) or two battery packs BP 4000.

The WMS 4500 is fully compatible to its predecessor WMS 4000. Additionally it offers 2 new frequency bands in the range of 500 – 530 Mhz and 570 – 590 Mhz.

All in all the WMS 4500 provides not only an unparalleled sound quality, but also an robustness and an feature set, which is unrivalled in this price segment.

HiQnet® - System Architect
With the optional HUB 4000 Q, AKG wireless systems can be integrated into a HiQnet® system. The wireless system can be remote-controlled and monitored with the Harman control software System Architect™ (from a PC), the AKG Wireless iPhone App (from an iPhone/iPod touch/iPad) or VM² (from a Soundcraft Vi mixing console). The setup and configuration of the frequency management of a multichannel wireless system is incredibly easy within the System Architect™ with tools like 1 Click Setup, RF Monitor, Device Manager and Environment Scan.
