Introduction

The SWA6SS is designed to distribute and amplify the RF signal from a pair of antennas to up to 6 SWM7000

Series receivers. You can also cascade multiple SWA6SS units to distribute the RF to many more receivers (see

block diagram detail on page 4).

Your Sabine Antenna Distribution Amp features very low inter-modulation distortion, high dynamic range and low

noise components, and reduces multiple antenna interference in multiple system usage.

Please refer to your SWM7000 Operating Guide for important information about the correct setup of your re-

ceiver.

Components

This Antenna Distribution Amp will allow you to connect up to 6 Sabine SWM7000 receivers to one set of anten-

nas — thus alleviating the “antenna farm” of multiple-receiver antenna placement — and improving reception as

well. This setup can be combined with the Sabine Extension Antennas (SWASS-EXT) for additionally improved

reception. Extension antennas must be purchased separately. Or you can use the standard antennas from your

receiver.

Installation Connections

1. Connect receiver Antenna 1 input to any RF Output 1 connector on the SWA6SS. Likewise, connect any

receiver Antenna 2 to any RF Output 2 connector on the SWA6SS.

2. Connect Antennas. You may use the supplied dipole antennas from your receivers and mount them either on

the front or back of the Antenna Distribution Amp. Make sure the dipoles (small rubber antennas) are mounted

so they can “see” the transmitters. To further maintain line of sight, replace the supplied antennas from your

receivers with Sabine Extension Antennas (SWASS-EXT).

3. Terminate any unused RF outputs. Failure to do this may result in poor performance or droputs. Your Antenna

Distribution Amp comes with 8 RF Terminators. Remove these as necessary to connect receivers, but save

them in case you change your configuration later.

3. Turn on Power switch.

NOTE: Using the set up illustrated in step number 4 on page 4 of this operating guide, one pair of SWASS-EXT

antennas connected to seven Antenna Distribution Amplifiers will accommodate up to 35 receivers, or 70 audio

channels.

General Information on Antenna Placement

Antennas used with the Antenna Distribution Amp should be placed in an open area within visual range of the

intended microphone locations. Note that the range of a True Mobility transmitter is about 100 meters, but that

structural objects can reduce that range. Extension antennas are recommended to maintain good reception

when the antenna divider is located far from the transmitters.

Antenna Placement Cautions

 Since the installation of the antennas influences the operating efficiency of the receiver, the most important

rule is to minimize the distance between receiving antenna and transmitter for better reception and perfor-

mance. Make sure the antennas can “see” the transmitters.

 Placing Extension Antennas: Position the one marked

LEFT

at stage left (on the left hand side of a

performer facing the audience) and so on. When you mount the extension antennas on a stand or on a wall,

make sure the short end of the triangle is up.

 In order for the system to be effective, both extension antennas should be in a good pickup position at all

times but separated by about ten or fifteen feet if the antennas are within 100 or so feet. Separate them about

20 to 25 feet in very large rooms or fields. If you put the antennas too far apart, i.e., at opposite ends of the

room, or in separate rooms, to improve coverage, diversity is defeated and you will get dropouts. In other
