PAM1 MK2 User Handbook Issue 1
Fixed Mode: Fixed Mode should be used when the audio signal under test should not change
despite the position of the yellow
‘Hear Box’.
In the example shown below, channels 1, 2, 3, 5
and 6 are selected as the L, R, C, Ls and Rs components respectively.
Their selection is denoted by the hori
zontal green cursor displayed below the ‘pair’ identification.
Providing the user does not switch away from the selected signal input or User Preset , then the
PAM1 will continue to measure the Loudness of the highlighted audio components. In this mode
of operation PAM1 does not make the assumption that the audio signals are present in the correct
SMPTE channel order for 5.1 sound
– by selecting the channel components individually, non
SMPTE order 5.1 audio can be chosen and measured. Unused channels can also be turned
‘OFF’
for Stereo , 4.0 or other custom applications. As per the ITU-R guidelines, the LF channel is not
subject to measurement.
Follow Mode: Follow Mode should be used when the audio signal under test is determined by the
position of the yellow Hear Box . In operation, as the user scrolls to hear audio components of the
displayed audio signal, the green Loudness cursor will move accordingly and measure the 5
component signals to the right of the selected source. In this mode of operation PAM1 makes the
assumption that the audio signals are present in the correct SMPTE channel order for 5.1 audio.
As per the ITU-R guidelines, the LF channel is not subject to measurement.
