There is no ‘standard’ for the relative gains between Analogue and AES3 so depending on the levels
delivered by the audio source, it may be necessary to adjust the digital input gain trims to normalise
them. It is possible to adjust the gain of the AES3 input using the Input Route AES3 Gain parameter.
For example, to achieve 0dBFS = +18dBu, set the AES3 trim to -­‐2dB. To achieve 0dBFS = +24dBu, set
the trim to +4dB.
This device will automatically lock onto any sample rate within the range 28kHz and 108kHz.
Networked Audio (Dante) Inputs
When the Digital Audio Network option is fitted, it is possible to select any channel(s) as being
sourced from this network. To do this, connect the audio network connection to the connection on
the rear of the Device, and set the relevant Input Route menu Source parameter to “Dante” (for
example.)
When the Digital Audio Network input is installed and routed, the “Net Audio” indicator above the
encoders will illuminate. This indicator will come on even if there are no cables plugged into the
networked audio port on the Device.
As for the AES3 inputs, it is possible to set the relative gain between an Analogue input and the
signals sourced from the Digital Audio Network using the Input Route Dante gain parameter.
The amplifier will automatically select the correct sample rate from the incoming stream.
For other details on the operation of the Digital Audio Network, please refer to the relevant
manufacturer’s documentation.
Gain and Polarity
The gain page of the input channel selected allows users to increase or decrease the amount of
signal going into the selected input. Using the “SELECT” encoder to highlight the Gain value allows
the value to be changed by the “ADJUST encoder in 0.2dB steps from -­‐40dB to +20dB. The presence
of an active Group Overlay parameter is indicated by the ‘[]’ symbol (See
Overlays ). This page will
also allow users to change the polarity of the selected input from normal to reverse. And to mute
the selected channel.
Delay
The delay page which controls the amount of delay associated with the input channel selected and is
adjustable from 0 to 998ms. The delay parameter is adjustable in fine steps at low values; the
adjustment becomes progressively coarser as the value increases. The presence of an active Group
Overlay parameter is indicated by the ‘[]’ symbol. See
Overlays .
High Pass Filter
System high pass filtering is provided for the input signal. Filter type is selectable from 1
st
order,
Butterworth, Bessel, Linkwitz-­‐Riley and Hardman. Filter slopes of up to 4th order or 24dB / octave
are provided. Not all filter types are available in all slopes. For example 18dB / octave Linkwitz-­‐Riley
filters do not exist.
The Hardman type filter is always described by its order as the filter becomes progressively steeper
rather than following a linear slope so a dB/octave description is not accurate.
