respond to a decrease of input level. The DECAY time can be varied between 1 and 10 which corre-
sponds to 200mS to 000mS on a semi-exponential scale.
'MIXER'
menu. Each band can be adjusted over a small range to provide small EQ changes. These controls
are limited in range to prevent excessive drive into the peak clipping stages and excess distortion being
introduced.
BAND1MIX:
-dB to +dB of level adjustment is available.
BAND2MIX:
-dB to +dB of level adjustment is available.
BAND3MIX:
-dB to +dB of level adjustment is available.
BAND4MIX:
-dB to +dB of level adjustment is available.
The
'CLIPPER'
menu contains the clipping controls that form the final peak limiting stages of the DSPXmini-
FM.
'BASSCLIP'
Controls the clip level of the mix of Bands 1 and 2
.
The clip level range is -6dB to 0dB refer-
enced to the main clippers output level.
'HFCLIPPLING'
This control redistributes high frequency peak control between the limiters and the HF
clipper
.
The range is 0 to 17 with 0 equating to full control by the limiters and higher numbers producing
less control by the limiters on a frequency dependent basis, leaving control by the HF clipper. This control
is similar to a variable de-emphasis control in the limiters side-chain control signals.
'MAIN CLIP DRIVE'
Controls the drive into the main output clipper that defines the systems peak clipping
ceiling. Adjustable over a -6dB to +6dB range.
'MAIN CLIPPER HARDNESS'
Another distortion controlling mechanism that helps to reduce IMD in the
final clipper. The range is 1 to 10 with 10 producing the least distortion control. A setting of 10 effectively
bypasses this control.
'OVERSHOOT CONTROL'
Controls how much the main clipper will pass overshoots to the composite
clipper. The range of overshoot control is 1 to 10 with lower numbers allowing more overshoots through
to the composite clipper.
'COMPOSITE CLIP
Controls the drive into the composite clipper which effectively sets the amount of
composite clipping. The range of composite clipping is -0.dB to +2dB.
The 'STEREO' menu contains all of the controls relevant to the DSP stereo encoder that generates the
multiplex signal.
'LEVEL'
Controls the output level of the composite MPX output. Range is 0dBu to +12dBU
'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 OUTPUT'
This controls the 19KHz pilot output reference signal which is available on the DSPXmini-
FM back panel. Options are enabled and disabled
The 'SCHEDULE' menu contains all the controls for the dayparting (REAL TIME CLOCK) preset switch-
ing.
'TIME'
Sets the time and day of the DSPXmini-FM’s Real Time Clock.
'DAYPARTING ON/OFF:
Enables or disables the scheduling.
'DP(X) ON/OFF'
Enables or disables an individual daypart schedule.
'DP(X)'
Sets the preset to switch to when this daypart is triggered.
'DP(X) START'
Sets the start time day and time of the daypart. There is also an ‘ALL days’ option.
'DP(X) LENGTH'
Sets the length in minutes that the daypart will run for.
