4.1.8 Optional 3 bands semi-parametric Equalizer [EQ]
Each of the input channels of the SX-ES64 can be equipped with an optional equalizer module. The design of
this powerful 3-band semi parametric equalizer is derived from previous models SONOSAX SX-S and SX-ST
whose effectiveness and sonic transparency has been proven on the field for decades.
• 80 Hz and 8 kHz: these filters have a shelve curve. Bass and treble adjustments are controlled by the
[80Hz ] and [8kHz] knobs within a range of ±15 dB
• MF: is a semi-parametric (sweep frequency) equalizer with a broad fixed bandwidth. ( Q Factor: -- )
The upper knob progressively adjusts the central frequency from 200 Hz to 8 kHz, the lower knob adjusts
the gain of the filter.
4.1.9 3 Leds peak-meter
This small peak-meter indicates the pre-fader level of the input channel. It also indicates an eventual overload
and the activity of the Limiter. The modulation is measured after the microphone preamplifier and after the
equalizer sections but before the fader of the channel. Thus it allows controlling the modulation level even if
the fader is closed.
The peak-meter works either in DOT mode or as a conventional Bargraph, depending on the Power On switch
position [ECO] or [ON].
Level indications: YELLOW: lights on as soon as the modulation reaches approx –20dB.
GREEN: lights on as soon as the modulation reaches the nominal level 0dB
RED: light on 10dB above nominal level
Input Limiters:
when the modulation reaches the threshold level of the limiter, both the Green and the
Red leds light on simultaneously.
Overloads:
The overload indication turns on 4 dB before the clipping is reached.
When in Bargraph mode, only the upper red led is lighting, all others turn off.
When in DOT mode, all leds light on simultaneously,
NOTE: the brightness of the leds varies automatically depending on the ambient light.
A light sensor is located under the secondary peak-meter
