Lake-enabled Amplier Reference
The attenuation value may also be set by tapping the numeric display at the top of the fader. A numeric
keypad opens allowing an absolute value to be entered.
20.6.2 Mute
2
The large mute button below the meter display activates the mute function for the power output channel.
The button changes color to red when the mute is applied, and the legend changes from UNMUTED to
MUTE. This function is equivalent to muting via the front panel for PLM and PLM+ Series devices.
20.6.3 Phase Reverse
3
A phase reverse button is provided which inverts the audio signal within the channel power output stage.
The button is blue and normally shows the legend +Φ; when applied it turns red and shows -Φ. Note that
this is an additional phase reversal at a later stage in the signal chain from the Lake Processing Modules, and
does not have an equivalent control via front panel operation, or elsewhere in the Lake Controller software.
20.6.4 Meters
4
Four vertical bar graph meters are depicted for each channel. These display output voltage (V), current (I)
and power (P), along with the amount of gain reduction applied by combined action of the various limiters
and protection circuitry (L). The meters correspond to the four bar graph meters on the PLM or PLM+ Series
front panel display in METER MODE, MODULE VIEW. Clip indicators for, respectively, voltage and current
are located directly above the voltage and current meter. Clip behavior is shown by a red light, using a fast
update rate to correctly indicate ballistics.
Two numerical displays are above the meter block. The top display switches mode dynamically to show the
parameter closest to clipping at the moment: voltage (V), current (I) or power (P). The bottom display shows
the current value of the Limiter meter.
20.6.5 Speaker Data Block
5
The display block below the meter section provides user feedback about the loudspeaker connected to each
power output channel.
▸ SPEAKER - The name shown here corresponds to that of the Module outputs and usually describes the
frequency band (e.g. Low, Mid, High) that a particular power output channel addresses.
For Modules with two or more identical output
channel names, the channel number will be
appended.
