ATL twotwo sub1, User Manual

Applications – 2.1 Configurations
All twotwo active subwoofers can be used to extend the bass response of any twotwo series monitor, or to
reproduce the LFE channel in a surround system. The diagrams on the following pages illustrate a variety of
configuration suggestions. The configurations and settings described here apply equally to all
twotwo
active
subwoofer models.
There are three important points to note. First, the twotwo loudspeaker (or optional remote controller) at
the start of the control chain acts as the system master controller and sets the volume for the entire system.
Secondly, the final loudspeaker in the chain must have the loop-back terminator plugged into the RJ45
Remote Thru socket. Finally, if an AES3 digital input signal is connected to any loudspeaker in the chain the
audio data is passed automatically over the RJ45 control line to the next monitor in the chain, and will be
used if the AES3 input is selected but not connected on that loudspeaker.
The diagram below illustrates one example of configuring the analogue audio and control connections in
a stereo configuration using a
twotwo sub1
active subwoofer to extend the bass performance of
twotwo
active monitors. In this arrangement the left and right analogue inputs are connected to the subwoofer,
and the digital output from the subwoofer (suitably high-pass filterered, if desired) is passed on to the
satellite
twotwo
monitors via RJ45 cable.
The optional remote controller is shown here as the first item in the control chain, with the loop-back
terminator plugged into the RJ45 Thru port on the last device in the control chain (in this case, the front left
twotwo
loudspeaker).
