Audio Inputs

The audio inputs are two 3-pin female XLR connectors located in the area labeled
BALANCED INPUTS. Signal is applied between pins 2 and 3, pin 1 is connected to ground.
When the Controller is linked to a signal source with balanced outputs, the XLR connections
are simply wired pin to pin (1 to 1, etc.). As a result of the balanced nature of the outputs (and
providing that balancing is respected by way of the connection to the amplifier), there is no hot
or cold pin - the Analogue TDcontroller being neutral regarding the polarity of the signal.
Output Level Switch
The 3-position output level switch is used to match the processor gain to the amplifier gain for
optimum signal to noise ratio. The three gain values available are +6, 0 or -6 dB. For minimum
noise floor the -6dB setting should be chosen, for maximum headroom the +6dB position
should be used.

Audio Outputs

The audio outputs are the three 3-pin male XLRs located in the area labeled BALANCED
OUTPUTS. The channel corresponding to each output connector is identified by the labels
Left, Right and Sub L+R (mono SubBass).
Signal is applied between pins 2 and 3, pin 1 is connected to ground.
When used with an amplifier with balanced inputs, the wiring of the output XLR is simply pin to
pin (1 to 1, etc.), the polarity of the signal being preserved if the source connected to the input
is also balanced (see previous section).
Sense inputs
The sense inputs of the three channels (left, right and SUB) are arranged on a
six-pole barrier strip set into the rear panel within the area labeled SENSE
INPUT. The Sense inputs are intended for connection to the output signals of
the amplifiers driving one cabinet of each the channels being used.
Connection is made via the female part - removable - of the connector
(supplied with the Controller) as outlined below:

cabinets will NOT BE PROTECTED if the sense lines are unconnected.
