Fourth, software control for the ND series receivers allows up to 70 re-
ceiver channels to be controlled from a single computer. This quick and
powerful control methodology means you can monitor and change trans-
mission 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 functions 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 equip-
ment 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 connecting the
Antenna Distributor to receivers (2 cables provide true diversity reception 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 or 915 MHz 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 transmis-
sion 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 circumstances,
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 up-
grade to more expensive cable, is to utilize a pair of Sabine Extension Antennas
(SWASS-EXT). These will connect to the antenna inputs of the Antenna Distri-
bution Amplifier, and offer increased range, better rear-source RF rejection, an
expanded 135 degree forward sensitivity, flexible mounting options, and signal
boost (see Section 12).

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