OUTPUT
All the needed settings to the outputs can be applies through here. Each of the available outputs
is separated in different sections.
Digital Output / Analog
and
Headphones Output
– is intended to control the peak output
level of the digital and analog output. A De-emphasis option is provided on both the analogue and
digital outputs. The following control options are available –
FLAT
(off),
50μs
(for Europe) and
75μs
(for USA).
The
Digital Output
should be internally or externally synchronized in order to be functioning
correctly. This is specified by the Sample rate setting. If the synchronization should be made
internally, a value from the standard range of
32
to
192 kHz
should be chosen. If the synchronization
method is external, the relevant option should be selected from the drop-down menu. When
External synchronization is chosen,
Sync loss s.r.
and
Sync tout
should be set in order for possible
loss of the audio at the digital output to be prevented. If such is present, the DB6400 will switch
to internal synchronization (the value being specified in
Sync loss s.r.
) after the defined
Sync
Timeout
expires.
MPX Out Level
should match the one of the transmitter (or link device if one is used).
HD Time Alignment
– Because of the time delay in the digital portion of the HD Radio audio
path, the analog and digital signals are supposed to be time-aligned. When the alignment is correct,
the transitional blend from analog to digital or vice-versa will be almost transparent. When setting
this parameter, have in mind that a time-alignment error of 1 millisecond will cause spectral
notches during transition which will be audible by the listeners.
IT IS RECOMMENDED
when the HD time Alignment is not used, the slider (value) to be set
to
0 ms
as by default. Otherwise the result will be undesired audio delay.
