Chapter 3 ‒ Axient System Features
Audio Quality and Digital Signal Processing
Axient delivers the cleanest, quietest, and most transparent wireless audio quality to date. With signal-to-noise ratios
exceeding 113 dB, Axient is the only choice for applications with dozens of microphones open simultaneously. Audio is
provided in both transformer-balanced analog and AES3 digital formats. Dual digital signal processors (DSP) maintain
precise audio tracking between transmitter and receiver over the whole audio dynamic range, resulting in superior linearity
and transparency in the presence of audio transients and sibilance.
Spectrum Management
Until now, quickly finding clean, ready-to-use frequencies could involve a variety of calculation and scanning tools, along
with careful analysis and manual programming. The AXT600 Spectrum Manager uses wizards to provide guided and
automated RF coordination tools to find the greatest number of available frequencies.
The Spectrum Manager offers precision wideband scanning and on-board compatible frequency calculation, as well as
backup frequency monitoring, ranking and deployment – all on demand. The Spectrum Manager not only captures a
detailed scan of your venue and displays it graphically, it can also listen in on a particular signal or store the data from a
site survey for later use.
Together with Shure Wireless Workbench 6 software, Spectrum Management tools open up a rich graphical interface for
viewing the RF world and choosing the optimal frequencies for all wireless channels on a production.
Interference Detection and Avoidance
Interference can come from anywhere - other wireless microphones, intercoms, digital devices – wreaking havoc with the
frequencies selected to make the show happen. Receivers are equipped with sensitive interference detection circuitry that
alerts users when a signal is compromised.
In the event of signal degradation, Interference Avoidance technology enables engineers to move to a clean, compatible
frequency - manually or automatically. Respond to an alert by either manually selecting a new frequency, or, when
used in conjunction with the Spectrum Manager, back-up frequencies are constantly monitored, ranked, and deployed
automatically the instant interference is detected.
Interference Detection and Avoidance delivers the confidence of knowing that no matter what happens, interference will
not ruin the show.
Frequency Diversity
Frequency Diversity enables audio transmission from a single source on two independent radio frequencies, providing
the best possible protection against interference for the most important performances. With Frequency Diversity mode
enabled, the receiver continuously analyzes signal quality and uses both frequencies to provide optimized audio on a
single channel.
With two independent RF signals transmitting the same audio, the presence of direct RF interference on one frequency
causes zero interruption. Instead of producing annoying dropouts or audio artifacts, the receiver seamlessly and
automatically switches to the other frequency, delivering clean, uninterrupted audio.
Transmitter Remote Control
ShowLink™ Remote Control enables real-time remote adjustments of all transmitter parameters using a wireless network
connection between linked transmitters and receivers. Whether performers are on stage in the middle of a show, or off
stage waiting for their cue, ShowLink lets engineers make crucial changes to their transmitter settings - without ever
leaving the control booth.
Remote frequency changes, gain adjustments, RF mute enabling, RF output power adjustments, and more are all
possible over the ShowLink network. Simply add a ShowLink Access Point to any network and instantaneous wireless
transmitter control is realized over a wide coverage area for up to 16 transmitters. Additional Access Points can be used
to extend coverage area and increase the number of supported channels. Real-time wireless remote control is now
possible with ShowLink.
