Power LED
The POWER LED illuminates whilst internal power is present within
the unit. If this indicator is not on, the most likely reason is simply the
absence of mains power, but under fault conditions it may also indicate
a ruptured mains fuse or a problem with the internal power supply
module.

LED
The source of this XLR input must be from the audio feed that is the source of
the echo. This is used by the cancelling algorithm to calculate what to remove
from the near end.
Near End Input
An XLR 3 pin socket is used for the NEAR END input channel and it can take
an analogue or AES/EBU digital feed. The input will automatically detect
whether the source is analogue or digital. It is electronically balanced, with
the following connections:
Pin 1: Screen.
Pin 2: Phase.
Pin 3: Non-phase.
The source of this XLR input must be from the audio feed that is
contaminated with the echo. It is from this feed, that the cancelling algorithm
will be subtracting it’s echo estimation to produce an echo free result.
Outputs
Analogue Outputs 1 & 2
The analogue outputs consist of two XLR male connectors professionally
balanced with following connections:
Pin 1: Screen.
Pin 2: Phase.
