IVM4500 IEM in-ear monitoring provides higher level audio quality and radio performance without compromising reference capability, and caters to all needs of engineers. Users in the tour and installed sound markets will find the easy-to-use technology ideal for onstage monitoring. The IVM4500 IEM allows the input signal to be processed individually to meet the requirements of both the artist and the sound system environment.

Designed and developed in Austria, with the experience and skill of AKG’s engineering team, the IVM4500 IEM offers a highly diversified system, which includes high-end radio electronic and a manual radio signal attenuator for more RF dynamic. Antenna diversity, with two matched antennas, and a new reference radio electronic design contribute to the stable signals of the receiver.

The SPR4500 IEM bodypack receiver features a rugged die-cast aluminum case. Auto Setup function for finding clean frequencies make setting up extremely easy.

Pre-programmed frequency preset groups support TV channels and ensure an easy and reliable system setup. Up to 14 intermodulation-free channels* can be used within a 30 MHz wide UHF band. In addition, up to 1200 frequencies can be selected manually.

The enhanced frequency setup shows the number of free channels, and new preset groups support TV channels. The quick frequency change function supports monitor engineers throughout performances to make their projects easily adjustable.

The IP 2 earphones connect to the SPR4500 bodypack receiver. These high quality earphones provide a wide-range sound with sharply contoured bass reproduction as well as excellent isolation to suppress high ambient noise levels encountered, e.g., on a loud concert stage.
