CROSSFADE (CONF.CROSSFADE) - – read/write
With this parameter, set the crossfade time between channels when switching from one to the next (in
seconds).
From 0 to 25.5 s
LINE 1 or 2 / MPX / PLAYER sub menu
These parameters are available as INPUT.LINE1.SW / INPUT.LINE2.SW / INPUT.MPX.SW /
INPUT.PLAYER.SW serial commands (see section 6.2.5).
THRESHOLD (INPUT.xx.SW.THRESH) – read/write
With this parameter, set the silence threshold level in dBFS on the selected channel.
From -90 to 0 dBFS
SILENCE (INPUT.xx.SW.SILENCE) – read/write
With this parameter, select the channel (L / R / L or R / L and R) on which silence detection must be
performed (not available on the MPX sub-menus).
L, R, ANY or BOTH
DELAY (INPUT.xx.SW.DELAY) – read/write
With this parameter, set the switching delay in seconds when audio loss occurs.
From 1 to 120 s
BACK DELAY (INPUT.xx.SW.BACKDELAY) – read/write
With this parameter, set the delay before returning to the highest priority channel, in seconds.
From 0 to 30 s
5.4.3. Line1 menu (ANA)
These parameters are available as INPUT.LINE1 serial commands (see section 6.2.5).
PRESENCE (INPUT.LINE1.PRESENCE) – read only
This parameter indicates the presence of audio signal at the input: none, left, right or L&R.
NONE, L, R, L&R
LEVEL (INPUT.LINE1.LEVEL) – read/write
This parameter is the max audio peak in dBu that can come from the transmitter on the LINE1 input. For
example, if the audio peak from the source is +6 dBu, this parameter must be set to +6 dBu for optimal
operation. If you do not know the audio source level, you may use an audio analyzer or display first level
measurements on the front panel to read the LINE1 LEVEL. Be aware that if the level is poorly set the
deviation may become too low or too high. This level is also called nominal level, i.e. the level producing the
deviation as set in the Modulation menu.
From -18 dBu to +18 dBu
