AIROCKS PRO ARX-900 USER GUIDE V1.0
Or the network can consist of one Master and up to 100 Relay units operating in a multi-hop
configuration:
Each AiRocks Pro unit can be configured to operate either as the
network “Master” unit or as a “Relay” unit (all AiRocks Pro units are
identical and include the same hardware and software). The number
of Relay units is limited by both the practical considerations
mentioned above, as well as network “polling” when using the
AiRocks Pro Network Management System (NMS) discussed below.
In an AiRocks Pro network, each AiRocks Pro Relay unit receives an
audio transmission from a single “upstream” unit, and then re-
transmits that same signal to one or more downstream units. Thus,
each AiRocks Pro unit creates its own point-to-multipoint sub-network. The input to each sub-network is
the signal received by the single uplink AiRocks Pro unit. Therefore,
an AiRocks Pro
network
is a group of
one or more sub networks all of which emanate from a single network Master
. Networks can be as
simple as one Master unit and one Relay unit in a point-to-point configuration, or as complex as
hundreds of units with multiple “branches” and “sub-networks”.
If there is a failure of one of the upstream AiRocks Pro units, the downstream units automatically begin
scanning for any other AiRocks Pro transmission within range. If an acceptable signal is found, it then
becomes the input signal for that sub-network, or any newly created sub-networks. Thus an automatic
switchover is accomplished without the need for manual intervention.
An AiRocks Pro network creates an extensive “cloud” of ultra-reliable wireless audio for both small and
large venue sound reinforcement applications. AiRocks Pro operates in the license-free 900 MHz
frequency band and includes fully automatic channel scanning and selection with automatic link
monitoring and optimization, so there is no need for complex frequency coordination or
intermodulation calculations.
AiRocks Pro units are designed to be very simple to install. When initially powered up, an AiRocks Pro
unit enters the Relay operating mode (unless it was previously configured as a Master unit) and begins
scanning for an upstream signal. When a signal is found, the unit begins sending the received analog
audio out to the connected speaker via an XLR connector. It (optionally) also begins relaying the digital
wireless signal, on a different frequency, to any downstream units within range. Front panel controls
