KS-342
VU scale These meters conform to the VU standard, providing
an averaged level reading. 0 VU marks the reference position.
BBC scale Developed by the British Broadcasting Corporation,
this peak meter standard goes from 1 to 7 (each step repre-
sents 4 dB) with a fast rise and slow fall time. The reference
level is “6”.
Nordic scale Another peak meter type, with 0 again being the
reference level, but the readings are from –42 to +12 dBu.
In each case, a peak LED is provided as part of the metering
system, which lights at 6 dB below maximum level.
MS operation
MS operation is usually carried out using a specialized micro-
phone designed for this kind of recording.
To use the MS facility with channels 1 and 2, make sure that
both channels 1 and 2 have their output destination selected
as MS.
Note that the dedicated XLR-5 connector can be used with ap-
propriately-wired microphones in this mode. It provides phan-
tom power, etc. in exactly the same way as the XLR-3 connec-
tors, and the line selector switches, etc. should be set appro-
priately.
The AUX inputs cannot be used for cascading in this mode.
The fader for channel 1 becomes the width control for the MS
signal, and the fader for channel 2 is the level control.
The fader gang switch (1-2) obviously cannot gang the faders
in MS mode—instead, it inverts the phase of the signal fed to
channel 2.
When monitoring, the L+R mode takes a new meaning, with the
decoded left and right signals being decoded.
AES/EBU output
The AES/EBU jack provides digital output in AES/EBU format,
at the selectable sampling frequencies of 44.1, 48 or 96 kHz.
The resolution is 20 bits.
