Features and scope of delivery Features and scope of delivery The UHF wireless system IEM 100 is an in-ear monitoring system especially suitable for profes‐ sional events, on rock stages and in concert halls, theatres and musicals. Your IEM 100 UHF wireless system consists of the following components: 9.5-inch stereo transmitter IEM 100 ST –...
Installation and starting up 4.2 Transmitter Rack mounting The unit has been designed for rack mounting in a standard 19-inch rack; it occupies one rack unit. Connecting the power supply NOTICE! Damage to the external power supply due to high voltages! The device is powered by an external power supply.
Installation and starting up Attaching the antenna Attach the included antenna to the back of the transmitter. To improve transmission quality and adapt to spatial conditions, it can be rotated and swivelled. If there is not enough space on the device for direct assembly of the antenna, for example because there is not much space in the rack, you can use the included coaxial cable to assemble the antenna separately from the device.
