Density EQ
works creating four floating
thresholds for the average sonorous energy
, in
four frequency bands: 80 Hertz, 1 KHz, 6 KHz
and 12 KHz. This equalization allows to obtain,
still in conditions of high loudness, a contour of
equalization based on the energy of bands
(instead of differences of relative gain between the
bands like in a conventional EQ).
To change a value, select a band and touch briefly
the JOG (note that the arrow becomes a pencil).
Turn the JOG to move the slider.
The
dotted area
is only for laboratory testing. It is
not a safe operating zone for audio processing.
Bass Clipper (Punch)
This control changes the threshold of a low band
limiter. The change of this threshold allows to
brings “punch” to the music’s below 80 Hz.
Increasing this threshold you increases the bass
peaks, but not the general bass loudness in a
noticeable way. You must use a monitoring
system with good low response to hear this
adjustment.
Values over -4dB must be carefully tested
according to the music that your radio station
plays, so it can produce audible distortion with
some music’s styles. All default presets uses this
control at the minimum (– 6dB) except “Melodic Hi
Boost”; “POP”; “Night FM” and “Rock”.
REMEMBER
• Changes occurs in real time, that is to say, as you
modify the value, the change will be listened on the air.
Chapter 5 Remote Control
462dsp can be controlled from a PC, by means of
RS-232
connection. The control software
“VirtualRack 462dsp” offers numerous features:
•
To change the current program to anyone of
the 30 presets from the PC using a drop-down
menu. The change take place in real-time.
• Create and edit the programs with an
advanced graphical interface.
•
Save the factory presets and user programs to
the HD, as backup or to transfer them to others
562’s units.
•
To automate changes of processing according
to a scheduling, to use different processing
programs from different hours from the day.
You can increase the loudness of your radio in
the rush hours of car traffic to arrive more force
at the radio receivers from car when they are in
the centric zone. For other schedules smoother
adjustments can be used, and finally last in the
night to set a very smooth programming, to
accompany music. The frequent change of the
processing ways tends to fight the auditory
fatigue that happens when the radio sounds
always equal throughout the day.
Note:
This
feature requires a PC connected to the 462’s,
running 462dsp VirtualRack..
•
Manage the 462dsp processing programs from
the Solidyne Audicom7 on-air automation
software. You can change the programs
according to the musical style.
The software runs on Windows 2000/XP. For
more details about this software, please refer to
the on line help contained into the CDROM.
5.2 Set up and connections
Interconnection is made using a standard cable
RS-232, with DB-9 female connectors in an end
and male in the other. The computer must have an
available serial port.
VirtualRack software automatically recognize to
the 462dsp, by exploring all RS-232 ports.
An
USB to RS-232
adaptor of good quality can be
used. Please refer to the on-line help for details
about the software.
