Following the success of its predecessor the IVM4, AKG proudly launches its IVM4500 IEM In Ear Monitoring System at NAMM. Building on a leading global reputation in professional wireless audio solutions and monitoring, IVM4500 IEM supports users with high quality audio and radio performance, with reliable reference capability. Users in the tour and installed sound markets will find the easy-to-use technology ideal for onstage monitoring.

Designed, developed and manufactured 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; enhanced frequency setup to show the number of free channels and supported TV channels and quick frequency change functions to support monitors, all within a rugged housing.  Battery life for the IVM receivers has been tested up to 10 hours.

“AKG’s IVM 4500 IEM in-ear monitoring hardware raises the bar for audio quality, as the user becomes more in-tune with their own sound,” stated Wolfgang Fritz, product marketing manager – tour sound, AKG.  “AKG continues to set the standard of high-quality, reliable performance, while IVM4500 IEM adds another groundbreaking, performance-enhancing technology to the industry.”

IVM4500 IEM features antenna diversity, with two matched antennae and a new reference radio electronic design, all of which provide stable signals for the receiver.  IVM4500 IEM’s audio quality boasts a high-end and powerful headphone amplifier, ultra linear frequency response and dual mode for individual mix.  The quick frequency change functions support monitor engineers throughout performances to make their projects easily adjustable.

“The in-ear monitoring market has become far more mature over the years,” continued Fritz.  “Artists demand, and rightfully so, an in-ear monitor that combines reliability, performance, power, comfort and quality audio – traits we’ve worked tirelessly on to ensure the IVM4500 IEM meets the standards of the performer.”

Included in the IVM4500 IEM system are the SPR4500 IEM diversity receiver, which automatically shows the number of free channels and supports TV channels with pre-programmed preset frequencies; the SST4500 IEM transmitter, which is adjustable to 10, 20, 50 and 100 mW depending on country laws; and the IP 2 ear-channel headphones, providing excellent acoustics and low impedance. The SPC4500 antenna combiner, the SRA2 W directional antenna and the RA4000 W omni-directional antenna complete the package.
