4.3.4 Pre-Fader Listening [PFL] or [AFL]
As mentioned above, then Pre-Fader Listening function [PFL] is automatically activated when the [LF CUT] knob is
released. As soon as a PFL is activated, it is signalled by the PFL Led located beside the headphone connector.
The corresponding channel is then audible in the headphone outputs in place of the current monitor selection, and
the modulation level of that channel is displayed on the main peak-meters.
Thus the gain and/or the LF Cut frequency can be precisely and individually adjusted, as its listening is not being
affected by the other channels. More than one channel can be summed in PFL mode by simply releasing
additional [PFL] knobs. When the LF-CUT knob is recessed, the PFL is turned Off and the monitor is audible again
as previously selected. When recessed, the Gain and the LF Cut are protected of any inadvertent miss-
adjustment.
NOTES: - by default the PFL is activated only by the [LF CUT] knob. By means of an internal soldering
jumper, the PFL can also be activated with the [GAIN] knob. (must be specified at the order)
- by default the pre-listening functions is taken PRE-Fader (PFL), by means of an internal
soldering jumper it can be changed to AFTER-Fader (AFL). (must be specified at the order)
WARNING: Any modification of the internal settings must be done by a qualified technician. Please contact
SONOSAX or your nearest SONOSAX dealer for any change.
4.3.5 3 Led modulometer
These small modulometers indicate the input level of the corresponding channel and also indicate the eventual
overloads and the Limiter's activity. The modulation is located after the microphone preamplifier but before the
fader of the channel. Thus it allows controlling the modulation level even if the fader is closed.
The modulomètres works either in DOT mode or as a Bargraph, depending on the Power On mode ECO or ON
Level indications: YELLOW: lights on as soon as the modulation reaches approx –18dB.
GREEN: lights on as soon as the modulation reaches the nominal level 0dB
RED: lights on when the modulation reaches 9dB above the nominal level
Input Limiters:
when the modulation reaches the threshold level of the limiter, both the Yellow and the Red
leds light on simultaneously.
Overloads:
The overload is indicated 2 dB before the clipping is reached.
When in Bargraph mode, only the upper red led is lighting
When in DOT mode, all leds light on simultaneously,
NOTE: the brightness of the leds varies automatically depending on the ambient light.
4.3.6 Channel fader ( Mix Volume )
The channel's faders [IN1 to IN3] controls the level of the modulation sent to the mix busses ( Mix Volume ).
Its range goes from minus infinite to +20dB.
The unity gain ( 0dB) is reached when the potentiometers is in vertical position ( line at 12 o'clock )
4.3.7 Panning [ L C R ]
The PAN switch routes the modulation of the corresponding channel [IN1 to IN3] to the stereo mix busses and
consequently to the main outputs as follow:
Position L: the modulation is routed to the Left output channel only.
Position C: the modulation is routed to both the Left and Right output channels simultaneously.
Position R: the modulation is routed to the Right output channel only.
