Figure 9.12.3: Temperature meter
view
Temperature View provides information about the current operating temperatures within the PLM and
loudspeakers.
Frame block:
▸ Line 1 TEMP METERS flag – confirms Temperature view
▸ Line 2 (blank)
▸
Line 3 Power supply temperature meter, denoted by 'PSU'. A bargraph meter displays the current PSU
temperature as a percentage of its maximum permitted value. The numerical percentage value is also
displayed at the right-hand end of the meter.
▸ Line 4 Processor temperature meter, denoted by 'DSP'. A bargraph meter displays the current tem-
perature of the main Lake processor as a percentage of its maximum permitted value. The numerical
percentage value is also displayed at the right-hand end of the meter.
Blocks 2, 3 and 4 are unused in Temperature View.
Output blocks:
▸ Line 1 Current actual temperature of the channel's power output stage (denoted by 'AMP') as a
percentage of its maximum permitted value. The numerical percentage value is also displayed at the
right-hand end of the meter in dB relative to signal clip.
▸ Computed temperature of voice coil of loudspeaker connected to the output channel (denoted
Line 2
by 'VC'). This parameter is calculated using the power currently being dissipated in the load and loud-
speaker data from the LoadLibrary Fingerprint as it is presented by the SpeakerSafe output. Displayed in
degrees Celsius. The numerical value is also displayed at the right-hand end of the meter.
▸ Computed temperature of magnet of loudspeaker connected to the output channel (denoted by
Line 3
'MAG'). This parameter is calculated and displayed in a similar way to the voice coil temperature.
