Multiple Systems Operation
Sabine 2.4 GHz Smart Spectrum
the antenna inputs of 6 receivers. A combination of 2-channel receivers
(SW72-R or SW72-NDR), a set (2 pieces) of SWASS-EXT-2, and one
SWA6SS, would reduce the antenna clutter of 12 transmission chan-
nels to a single pair of extension antennas. See Section 12 for more
information about setup and use of the SWASS-EXT-2.
4.
Fourth, software control for the ND series receivers allows up to 70
receiver channels to be controlled from a single computer. This quick
and powerful control methodology means you can monitor and change
transmission channels, mic modeling, compression and de-essing —
in short, all front panel controls — from a remote laptop or desktop. In
addition to simplifying multiple unit operation with remote front panel
controls, the remote software provides additional features and func-
tions not available from front panel control. See Section 13 for more
information about setup and use of the Remote Software.
11.2. Antenna Distribution Amplifier
Sabine's optional accessory SWA6SS Antenna Distribution Amplifier is ideal
for simplifying antenna set up when multiple receivers are used, by using a
single pair of antennas to replace pairs for up to 6 different receivers. Standard
equipment packed with each Antenna Distributor includes an AC power cable,
and 6 pairs of 1-meter long jumper cables (RG-58 AU foam core) for connect-
ing the Antenna Distributor to receivers (2 cables provide true diversity recep-
tion to each receiver).
For best results, the Antenna Distribution Amplifier should be positioned close
enough to the receivers to minimize cable runs. In most applications, you can
use the standard Sabine 2.4 GHz antennas supplied with any of the receivers
to connect to the terminals on the Antenna Distributor, and then connect (in
matching pairs) the jumpers to all your receiver antenna connections (up to 6
receivers, 1 pair per receiver).
Care should be exercised when using longer cables, due to possible trans-
mission signal loss (approximately 1.7 dB/meter). Using the "rule-of-thumb"
that a signal loss no greater than 6 dB will prove acceptable in many circum-
stances, you may be able to use RG-58 cable up to 3 meters or so in length.
However, a better strategy than moving the Antenna Distributor to a better
position, and risking excessive transmission loss back to the receivers or
requiring an upgrade to more expensive cable, is to utilize a pair of Sabine
Extension Antennas (SWASS-EXT-2). These will connect to the antenna inputs
of the Antenna Distribution Amplifier, and offer increased range, better rear-
source RF rejection, an expanded 135 degree forward sensitivity, flexible mount-
ing options, and signal boost (see Section 12).

tenna Distribution Amplifier, please refer to the operating guide included with
