Overdrive the main clipper to hear the effect of this control and then back the drive back down after
the finesse control is set to your taste.
'OVERSHOOT CONTROL' Controls how much the main clipper will pass overshoots to the compos-
ite clipper. The range of overshoot control is 1 to 10 with lower numbers allowing more overshoots
through to the composite clipper.
'ITU LIMITER' Sets the threshold of the integrated ITU limiter or turns it off. When activated, the unit
will comply with the ITU BS.412 standard that requires limiting the power of the broadcast MPX sig-
nal. This limiter will drastically reduce the loudness of your signal and should be used only if the regu-
lations in your country require you to comply with ITU BS.412. Otherwise set this parameter to off.
The thresholds are calibrated in dB relative to the ITU BS.412 reference.
The 'OUTPUT' menu contains all of the options and parameters relating to the control and conditioning
of the audio outputs.
The 'ANALOG' menu contains the controls relevant to the analogue outputs.
'OUTPUT LEVEL' Controls the output level of the analogue output. Range is -12dBu to +24dBu.
'MODE' This parameter sets the output mode of the analogue and headphone outputs. The available
options are FM, delayed FM, same as AES2 and MON representing the distortion controlled clipping
path, delayed distortion controlled clipping path, same as selected on AES2, the look-ahead limiting path
and the lower latency talent (DJ) monitor path.
'DE-EMPHASIS' This controls the de-emphasis setting of the analog and headphone outputs. Options
are Off, 50 µs (Europe) and 75 µs (USA)
'HEADPHONE LEVEL' Sets the output level of the front panel headphone port. Range is 0 to 25 with
higher numbers equating to more volume. The headphone port follows the output mode and de-emphasis
settings of the analogue outputs.
The 'DIGITAL' menu contains the controls relevant to the AES/EBU digital outputs. DSPXtreme features two
AES/EBU outputs, each of which is separately adjustable with the following controls:
'OUTPUT LEVEL' Controls the peak output level of the digital output. Range is -12dBFS to 0dBFS.
'MODE' This parameter sets the output mode of the digital output. The available options are FM, delayed
FM, DR and MON representing the distortion controlled clipping path, delayed distortion controlled clip-
ping path, the look-ahead limiting path and the lower latency talent (DJ) monitor path.
'RATE' This parameter sets the output sampling rate for the AES/EBU digital output. The available rates
are 32 KHz, 44.1 KHz, 48 KHz, follow digital input rate and follow external sync rate.
'DE-EMPHASIS' This controls the de-emphasis setting of the digital output. Options are Off, 50 µs
(Europe) and 75 µs (USA).
The 'STEREO' menu contains all the controls relevant to the DSP stereo encoder that generates the multi-
plex signal.
'OUTPUT LEVEL' Controls the output level of the main composite MPX output. Range is 0dBu to
+12dBu. Secondary composite MPX output has an adjustable potentiometer available on the back of the
unit.
'PILOT LEVEL' This parameter sets the level of the composite signals 19 Khz pilot tone. The adjustable
range is 6% to 12% and an OFF setting for mono applications.
'PILOT PROTECTION' Activates a narrow notch filter that protects the pilot in the multiplex signal. If
you are using lots of composite clipping, this filter will protect the pilot region from being contaminated
with harmonic products. As a consequence, you might need to readjust the MPX output level slightly as
activating this filter may increase overshoots slightly (how much will depend on the amount of composite
clipping used).
'ITU LIMITER' Sets the threshold of the integrated ITU limiter or turns it off. When activated, the unit will
comply with the ITU BS.412 standard that requires limiting the power of the broadcast MPX signal. This
