4.3 FRONT PANEL
The front panel of the SX-M32 provides with all functionalities commonly used during a recording session such as
the Gain control of the input channels, the mix bus assignment L-C-R, the mixing of the channels, the monitoring
etc. Each function is fully explained in the following chapters.
INPUT SECTION [ IN 1 to IN 3 ]
This section treats all functionalities concerning the input channels such as the input gain, the sweep LF-Cut, the
mixing level and the assignment to the mix bus. It also contains a small modulometer to control the modulation
level and to indicate eventual overload
4.3.1 Input Gain control [GAIN]
The gain potentiometers are retractable. A light pressure the [GAIN] knob releases the gain potentiometer.
It progressively controls the gain of the Mic/Line preamplifier of the corresponding channel [IN1 to IN3] within a
range of 12dB to 78dB.
NOTE: the overall gain range is quite wide and therefore the gain must be carefully adjusted. An
excessive gain will reduce the available headroom and may lead to an overload. A gain being set
too low degrades the signal to noise ratio.
4.3.2 Input Limiters
Each of the 3 input channels has its own Limiter. It is part of the microphone pre-amplifier design and it acts as a
protection Limiter. The threshold is set 2 dB below the clipping level and can not be modified.
When the modulation level reaches the threshold, the Yellow and the Red Leds are lighting simultaneously.
4.3.3 Sweep LF-Cut [LF CUT]
The sweep LF-Cut potentiometers are retractable. They progressively adjust the LF-Cut frequency of the
corresponding channel [IN1 to IN3] and also automatically activates the PFL (pre-fader listening) as soon as the
knob is released.
The LF-Cut is adjustable from 25Hz to 340Hz with a slope of 12dB per octave
NOTE: The LF-Cut circuitry is located right after the microphone preamplifier and is independent from the
"Pre LF-Cut" which is located before the microphone preamplifier
