The AKG IVM 4 is the first wireless system ever to combine all the features required for professional in-ear monitoring in a single, compact device. The IVM 4 system features an integrated dbx compressor, an equalizer offering a large number of EQ presets and in-ear-optimized binaural room simulations that provides musicians, vocalists and presenters with outstanding high-performance signal processing flexibility for a natural listening experience with more life-like imaging.

The IVM 4 allows the input signal to be processed individually to meet the requirements of both the artist and the sound system environment. Unique integrated signal processing for a natural listening experience and a complete set of inputs and outputs make the IVM 4 an ideal tool for professional applications. The IVM 4 system includes the SST 4 stereo transmitter, SPR 4 bodypack reciever, and the IP 2 earphones.

SST 4 stereo transmitter
The SST 4 is the first stereo transmitter ever to combine all the features required for professional in-ear monitoring in a single, compact device. The SST 4 allows the input signal to be processed individually to meet the requirements of both the artist and the sound system environment. An integrated dbx compressor, many EQ settings, and optimized binaural room simulation algorithms provide outstanding high performance signal processing flexibility. Preprogrammed frequency preset banks ensure an easy and reliable startup. 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. These features allow the IVM 4 to be used together with any AKG WMS 400 or WMS 4000 wireless microphone system. The SST 4 lets you adjust the RF output within the approved range, which is particularly important when the in-ear monitor system is used together with a complex wireless microphone system. This allows optimum system matching for improved reliability.

SPR 4 Bodypack Reciever
The SPR 4 bodypack receiver features a rugged die-cast magnesium case. Auto Setup and Environment Scan functions for finding clean frequencies make setting up extremely easy. The 30 MHz bandwidth allows manual selection of 1200 frequencies or the system chooses from preprogrammed frequency preset banks. The SPR 4 provides a backlit display and jog control for ease of use. The display indicates the received signal strength and battery status along with other parameters. Integrated charging contacts allow the optional BP 4000 battery pack to remain inside the receiver whilst being charged on the CU 4000 charger (optional). The BP 4000 will be charged to capacity in only one hour, and can power the SPR 4 for about seven hours.

The only control the artist needs to operate is an ergonomically shaped volume control with integrated on/off switch. Placed in the center of the SPR 4 top panel, the volume control with its clearly discernible detents can be operated intuitively even if it is positioned outside the user's field of vision. An Individual mix function allows a personalized monitor mix to be set up even where only a small sound system with no separate monitor mixer is available. To accommodate the individual preferences of users, the SPR 4 has been designed to drive a large number of different types of earphones.

IP 2 earphones
The IP 2 earphones connect to the SPR 4 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. An integrated sliding cable tie and the supplied soft-rubber earmolds in three different sizes enable the earphones to adapt to every shape of ear and head.
