A bargraph meter displays the current PSUtemperature as a percentage of its maximum permitted value. The numerical percentage value is alsodisplayed 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 numericalpercentage 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 apercentage of its maximum permitted value. The numerical percentage value is also displayed at theright-hand end of the meter in dB relative to signal clip.Line 2▸ Computed temperature of voice coil of loudspeaker connected to the output channel (denotedby ‘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 indegrees Celsius. The numerical value is also displayed at the right-hand end of the meter.Line 3▸ Computed temperature of magnet of loudspeaker connected to the output channel (denoted by‘MAG’). This parameter is calculated and displayed in a similar way to the voice coil temperature.
