The Antenna

For most basic wireless applications, the antenna supplied with a system’s re- ceiver is more than adequate. As your wireless system grows, however, you may find you require one or more remote antennas to accommodate the increased number of channels. Receivers in large setups are most often rack-mounted. If the antennas are left inside the rack, per- formance can be degraded due to the rack and metal housings in the transmis- sion path. Remote antennas allow the receiver antennas to be placed in a loca- tion which provides better reliability and reception.

In order to manage additional antennas, Sennheiser offers a variety of useful tools. Antenna splitters, such as the ASA1, allow a single pair of antennas to “feed” multiple receivers. The new active ASA1 allows wideband splitting of antennas and can be daisy chained for use with multiple channel setups. Because the ASA1 is active, boosters are typically not required unless the antenna cable runs are in excess of about 90 feet.

Antenna combiners, such as the AC3, are similar to splitters but are used only with wireless monitoring systems to combine up to four transmission signals onto a single transmit antenna.

Both the ASA1 and AC3 power the G3 receivers/transmitters they are connected to right through the antenna cable – a cool concept!

A1031-U

Passive, omni directional UHF antenna which can be mounted on a stand. Receives/trans- mits signals in a Taurus or “donut” shaped pattern.

ASA1

1:4 active antenna splitter. Allows up to four receivers to operate off a pair of antennas.

Wireless Monitor Systems

Another revolution in the world of live sound is the widespread use of wireless monitor systems. Since such systems offer better signal-to-noise ratios without feedback, they provide the user with great freedom of movement and control. In addition, wireless monitor systems provide excellent hearing conservation since they do not need to be loud in order to “cut through the mix.” Add in great cost-ef- ficiency, space-savings, and portability when compared to hauling ordinary monitors, and you can easily see why wireless monitoring is so popular.

The evolution wireless G3 monitor system is engineered with the same principles of high quality and durability as all other evolution wireless G2 systems. The SR300G3 transmitter features 1/4” and XLR balanced inputs for easy compatibility, and robust output power (30 mW) for extended range and signal stability. With preset UHF frequencies (from the user-selectable 1,680 available) and multiple channel operation, the system can provide wireless monitoring for every performer on stage. Engineers will love the built-in Ethernet port for computer control with Sennheiser WSM software for both PC and Mac computers. The unique Focus feature allows you to switch between standard stereo (2-channel) monitoring and Focus Mode, which provides limited mixing capabilities (the ability for performers to pan between their vocals and the instrumentation, for instance). Frequency number and channel num- ber display functions provide clear indication, and the system’s channel Naming function allows you to add a custom name to each preset. In addition, convenient front-panel headphone monitoring allows for quick and easy monitoring of each channel’s signal.
