Multi-channel Wireless Mic System Hookup 1. Rack mount your gear. The GA3 rack adapter can accommodate two half-rack sized units, such as a receiver, a splitter, or an AM2 kit (which includes two front mounts for antennas). Consider how many channels you will need, and select the appropriate number of GA3 units (see the sample drawings on the following pages to get an idea of how this works). 2. Determine whether you will need an antenna splitter(s) based upon the number of channels you require. A rule of thumb is that you will need a splitter for every four channels. If doing more than 8 channels, you will need to group them in groups of 4, or 8 units with another "master" ASA1 which takes the feed from the antennas. Another great advantage which splitters offer is that they will provide DC power to the receivers right through the connection cable. A single splitter will power up to four receivers. 3. Determine where you wish to place your antennas. If you wish to keep them at your rack, you will need an AM2 kit for every splitter you have, unless you optimize the cascading feature of the splitter, which allows the operation of eight receivers of the same frequency range from one pair of antennas. An AM2 it front-mounts two antennas, and takes a total of 1/2 a rack - keep this in mind when configuring your system. If, instead, you wish to remote-mount your antennas to increase the coverage area, you will need to utilize A 1031-U antennas, which are typically mounted to mic stands or WM1 wall mounts. Since the antennas will be used away from the rack, it is not necessary to use AM2 kits. Antenna Splitter and Mounting Packages Considering the number of individual items required to rig an evolution wireless G3 receiving antenna splitter system, we have put together seven packages to make ordering these items simpler. These packages address seven common scenarios. NOTE: The antennas supplied with all ew rack-mountable receivers are to be used only in chassis-mounted (rear jacks), or in conjunction with the AM2 front-mounting kit. These are ground plane devices and are never to be used as a remote antenna solution on the end of a cable. Due to the variables in one installation to another, the following items are not included with Sennheiser splitter/combiner kits. It is suggested you check and see if you may require any of the following: • GA3 rack mounts (which are not included with 100 series) • RG58 cable to run to your antennas • Mounting brackets for remote antennas • Rack screws The following is a list of splitter and antenna kits that Sennheiser currently offers for G3 units: G3OMNIKIT4 Active splitter kit for four receiver system using omni-directional remote paddle antennas, includes ASA1/NT, two A1031-U, GA3 G3OMNIKIT8 Active splitter kit for eight receiver system using omni-directional remote paddle antennas, includes two ASA1/NT, two A1031-U, GA3, two BB1 G3DIRKIT4 Active splitter kit for four receiver system using directional remote paddle antennas, includes ASA1/NT, two A2003-UHF, GA3 G3DIRKIT8 Active splitter kit for eight receiver system using directional remote paddle antennas, includes two ASA1/NT, two A2003-UHF, GA3, two BB1 G3FRONTKIT4 Active splitter kit for four receiver system using front-mount antennas, includes ASA1/NT, GA3, AM2 G3FRONTKIT8 Active splitter kit for eight receiver system using front-mount antennas, includes two ASA1/NT, two GA3, AM2, two BB1 ASA1/NT Active antenna splitter with DC power distribution for G3 receivers, includes required NT1-1 US power supply and eight 20" BNC cables AC3/NT Active antenna combiner with DC power distribution for IEM transmitters, includes required NT3-1-US power supply and four 20" BNC cables G3IEMDIRKIT4 Active combiner kit for four IEM transmitters with DC power distribution, includes AC3/NT, GA3, A2003-UHF 20
