Factory and User Gain are provided for each Module output. These two stages provide a level of security and control
for the system designer (Factory) and a further level of adjustment for the user (User), both of which combine to
balance the level between frequency bands in a multi-way crossover.
Generally, output gain values are configured within a Module / loudspeaker preset file and should not need to be
adjusted further.
12.4.5 Attenuator
An attenuator gain adjustment is provided for each power output channel in the 20000DP. This control replaces the
traditional volume control found on conventional amplifiers and should typically be left at 0 dB during use.
12.4.6 Amp Gain
The Amp Gain corresponds to the gain adjustment in a conventional separate loudspeaker processor and amplifier
system. When using a pre-defined Module loudspeaker preset file, the Amp Gain settings will normally remain as
defined in the file. The limiter and output gain settings of the Module were configured with this gain setting and
will not be automatically compensated if changes are made. This configuration scheme, though unusual, allows for
compatibility with legacy Dolby / Lake products.
12.5 Gain / Level Optimization
12.5.1 Maximize Volume Capability
To maximize the volume capability of the device, ensure there is sufficient headroom in the signal path to avoid
clipping before the limiters engage. It must be possible to achieve enough gain through the device to engage
the limiters and realize a high average SPL. As an optimal setting, allow for a headroom of 10 dB or more for all
channels; the simplest way to accomplish this is to increase the Module input gain.
12.5.2 Minimize Noise
To help provide the best volume to noise ratio, use an AES or Dante digital input signal wherever possible. If using
analog inputs, ensure that unused or unnecessarily high headroom is not introduced at the input to the device. If full
or high average power is not required, the Module input gain may be reduced.
