PLM+ SERIES Operation Manual rev 1.0.0

10.3.3. Module Input Gain

Input Gain is used to adjust the level between different speaker cabinets in the system. This gain can remain at
0.00 dB unless a lower level is required for the cabinet/s driven by this Module.

To adjust, navigate to MODULES > EQ/LEVELS > LEVELS in the Lake Controller. Please refer to the Lake
Controller Operation Manual for further details.

10.3.4. Module Output Gain

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 (Contour configuration) or the
Module output level (Mesa configuration).

1. Factory Gain is set by the system designer and can be hidden within the Module file. The Factory Gain
parameter is only accessible when the Module is unlocked and the Lake Controller is in Designer Mode. Adjust via
MODULES > LEVELS > METER OPTIONS > ADJUST FACTORY.

2. User Gain is editable by a user unless the system designer has locked away the parameter; adjust via
MODULES > LEVELS.

Generally, output gain values are configured within a Module / loudspeaker preset file and should not need to be
adjusted further.

10.3.5. Attenuator

An attenuator gain adjustment is provided for each power output channel in the PLM+. This control replaces the
traditional volume control found on conventional amplifiers and should typically be left at 0 dB during use.

To adjust, navigate to I/O CONFIG > EVENTS & CONTROL > STATUS in the Lake Controller. Please refer to the
Lake Controller Operation Manual for further details.

10.3.6. 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 other Lake products, assuming the amplifier gain is set as specified in the speaker preset.

When creating a loudspeaker preset Module file, adjust by navigating to I/O CONFIG > EVENTS & CONTROL >
CONTROL in the Lake Controller. Please refer to the Lake Controller Operation Manual for further details.
