Installation and starting up 4 Installation and starting up 4.1 General Information Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively. Create all connections while the device is off.
Installation and starting up 4.2 Receiver Rack mounting The unit has been designed for rack mounting in a standard 19" rack; it occupies one rack unit (RU). Connecting the power supply NOTICE! External power supply The device is powered by an external power supply. Before connecting the external power supply, ensure that the input voltage (AC outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual cur‐ rent circuit breaker.
Installation and starting up Attaching the antennas Attach the included antennas to the rear panel of the transmitter. To improve the transmission quality and to adapt to the spatial conditions they are rotatable and swivelling. In case the space provided on the device for direct assembly of the antennas is not sufficient, for example because the space on the rack is narrow, you can use the optionally available coaxial cable to assemble the antennas separately from the device.
Installation and starting up Connecting microphone of instrument n Ensure that the transmitter is switched off. n Connect the microphone or instrument cable to the input on the transmitter (mini-XLR panel connector). n Turn on the transmitter and check the transmission by using the microphone or instru‐ ment. If necessary, adjust the amplification of the transmitter and the levels on your mixing console or your amplifier. 4.
