2.1 MPX level
The first adjustment is the modulation level on the
transmitter (please see “1.4.2 – Modulation level”).
2.2 Audio settings
Audimax 362HD was designed to offers an easy
and very intuitive operation. You don’t need to have
specialized knowledge to start up the processor and
to adjust the sound settings. Simply begins placing
all knobs to the center position. That is all! You will
be on-air with a great sound. Soon you will have to
customise the sound according to the musical style
of your radio, for which we recommends you to read
the following explanations kindly.
2.2.1 Input level
Audimax 362HD has an automated control for the
input level. The rear panel presents balanced inputs
(+4dBu) and unbalanced inputs (-10 dBV). Make
sure to connect the mixing console to the appropriate
inputs according its nominal output level.
Automatic input gain control (AGC) eliminates
variations in characteristics of the operation of the
mixing console level, and compensates for
differences in level of the recorded material. That is,
if the level from the console remains very low for
some time, the processor will compensate its input
to maintain a constant output level. If the output
level of the console exceeds constantly 0VU; AGC
attenuate the signal. In this way the program signal
reaches the processing steps with constant level
and sound on-the-air is consistent, always with the
same degree of processing.

To verify that the input level is appropriate, observing
the three LEDs on the AGC, located on the front panel
operate properly: The first LED (green) should be
always on in the presence of music or voice; the
second (yellow) flashing audio peaks or always on.
The third LED (red) should never be turned on
permanently.
2.2.2 Customizing the sound
All adjustments are made from seven knobs located
in the front panel.
The stage Dynamic Equalizer is a 3-bands
dynamic audio equalizer that allows reinforcing
certain frequencies, usually the bass, to have a
sound with ‘punch’, ideal for the car-stereos. Unlike
the conventional EQ’s, whose action is lost for high
levels of modulation, this EQ emphasizes its action
when higher is the modulation.
To adjust the dynamic EQ, make sure that the
multiband compressor is operating. For this, see the
LED’s meters located at the right; the first LED’s
must be illuminated.
In these conditions, turns the Dynamic Equalizer
knobs (Low, Mid and Hi). Turning the knobs to the
left, the response of the dynamic EQ will be flat.
Turning the knobs to the right, a boost in this band
takes place. When you boost a band, the action of
the compressor for this band increases.
NOTE: Dynamic Equalizer make changes over the
attack times of mutiband compressor.
The Band Energy section increases the peaks
density for the band, achieving high loudness
signals. This control changes the recovery times of
the audio compressors. It must be settled according
to the musical style and the kind of sound that
you’re looking on-the-air: compact with high
loudness and “punch'’, turning the knobs to the right
(fast recovery times); or more soft and smoothly,
with the knobs at the left (slow recovery times).
Multiband Compressor is the core of the
processing system, constituted by 3 independent
audio compressors that works on 3 frequency
bands: Low, Mid and Highs.
The Multiband control changes the input gain of
the compressors . This control affects more
radically the output level of the Audimax 362HD.
Turning this knob to the left you will obtain a
smoother sound, with little processing and therefore
