Putting the receiver into operation Putting the receiver into operation Preparing the receiver for use Setting up the receiver on a flat surface Fitting the device feet Do not fit the device feet when mounting the receiver into a 19” rack. 왘 Clean the base of the receiver where you want to fix the device feet. 왘 Fit the device feet to the four corners of the receiver. 왘 Place the receiver on a flat, horizontal surface. Please note that the device feet can leave stains on delicate surfaces.
Putting the receiver into operation Connecting the rod antennas to the rear of the receiver 왘 Connect the rod antennas 씏 (see diagram). 왘 Align the antennas in a V-shape. 씏 씎 씋 Mounting the antennas to the front of the rack To mount the antenna connections to the front of the rack when rack mounting the receiver, you require the AM 2 antenna front mount kit (optional accessory). The AM 2 consists of: • 2 BNC extension cables • 4 washers • 2 nuts (screw-in BNC socket to BNC connector), , .
Putting the receiver into operation 왘 Connect the rod antennas 씏 to the two BNC sockets of the BNC cables 왘 Align the antennas upwards in a V-shape. . Connecting remote antennas (optional accessories) CAUTION! Danger of damage to the antennas To supply an active direction antenna (e.g. A 3700 for the UHF range) or an antenna booster (e.g. AB 3700), a direct voltage (which cannot be switched off) is output via the antenna sockets of the receiver.
Putting the receiver into operation Connecting an amplifier/mixing console The receiver’s XLR-3M socket 쐉 and the ¼” (6.3 mm) jack socket 쐈 are connected in parallel.
