Tutorial
If
AUTO
mode is selected and the unit is in
PRE
, the
AZX
+ will act purely as a
phase meter, and it will then be apparent when you have timing errors in any
material you pass through it.
If you detect timing errors and wish to correct them, the suggested procedure is
as follows:
1
Ensure that the
AZX
+ is in
POST
.
2
Select
AUTO
and
STEREO
modes. If the result is satisfactory you need
proceed no further.
Sometimes the material will contain information that hinders the operation of
the autotracker, and this can cause the
TIME SHIFT
to swing or ‘hunt’ for the
correct value. If this happens, you should use
MANUAL
mode.
3
Put the
AZX
+ into
MANUAL
,
MONO
, and
DIFFERENCE
modes.
4
Sweep the time relationship using the
ADJUST
control. Do so until you find the
TIME SHIFT
at which the perceived signal is minimised.
Hint: You can often recognise this by noticing that vocalists and solo instruments
disappear from the mix, leaving just the reverberation behind.
5
Return to
STEREO
mode, and use
PRE
/
POST
to compare the uncorrected
and corrected signals.
6
If you are satisfied with the results, restart the audio material and allow the
AZX
+ to process it.
Note: You may adjust the
TIME SHIFT
manually while the material is playing without
introducing glitches. This may be of use when you wish to use
MANUAL
mode but
know that there are a limited number of changes in the
TIME SHIFT
during the
course of the material.
Note: You may use
MONO SUM
mode to assess the mono-compatibility of the processed
and unprocessed signals. In this mode, the level is reduced by 6dB to avoid the
possibility of signal clipping.
