Sabine SWM4000 Smart Spectrum

Wireless

Note: transmitting devices such as cellular phones and two-way radios may interfere with

wireless audio transmissions. Keep your transmitters and receivers away from these and

other potential sources of interference.

Congratulations on purchasing your Sabine SWM4000 Series Wireless Microphone System. This system

is specially designed to provide you with excellent audio quality, ease of use, and reliability.

Frequency Bands The SW4000 series is available in several frequency bands to accommodate various

local governmental regulations throughout the world. The frequency band of your system is represented

by the numbers appended to the part number. For example, the SW40-RM3-U-915 operates in the 915

MHz band while the SW40-RM3-E-860 operates in the 860 MHz band.

The band recommended for the US and Canada, along with Central and South American is the 915 Mhz

band. This band is immune to interference from analog and digital TV, mobile or smart phones, and most

WIFI devices. It operates with up to 8 concurrent users in the same location.

Contact your local distributor to determine the best band for your location outside of the Americas. Or, visit

Installing the SW4000 system in your sound system.

Antennas. Antennas pick up the signal from the transmitters and transfers it to the receiver where it con-

verted to an audio signal. A pair of SWAANT dipole antennas are included with your system. Antennas are

like the “eyes” of the system. You will hear dropouts if the antennas cannot “see” the transmitter. Antennas

cannot “see” through steel or concrete. If your antennas are mounted on the back of the receiver, rotate

the receiver body around so that the antennas are in the line of sight of the transmitter.

A receiver mounted in a rack must use the back-to-front cables and have the antennas mounted in the line

of sight of the transmitter on the front of the rack. Also, dipole antennas should be orientated to the 11:00

and 2:00 positions for the best reception.

If the antennas are blocked or shadowed, you should replace the SWAANT antennas with Sabine’s

SWASS-EXT-3 external antennas. Make sure you specify the frequency band of your system when

you order.

Audio Connections Your receiver has both a balanced XLR and unbalanced ¼-inch audio jacks on the

back panel to connect the receiver to your mixer or powered speaker. Use the balanced jack whenever

possible.
