Monitoring System; Channel Gain; Channel Equalization; Genuine Ecler Faders & Crossfader - Ecler HAK310 Mode D'emploi

4.2. Monitoring System

The HAK is equipped with a flexible and easy monitoring system that will allow the
performers to finely tune PFL (Pre-fader listening) and PGM (Program Monitor) levels of the main
inputs through the VU-METER and the HEADPHONES.
For HEADPHONES monitoring, the PGM/PFL switch (26) allows you to select between
post fader or pre-fader listening. In PFL position, the PFLs crossfader (28) allows you to quickly fade
between the two prelistening channels PFL.

4.3. Channel gain

All the HAK310 input channels have accessible input sensitivity GAIN (17) and ADJ (14)
controls. These controls have the function of compensating for differences of level existing between
the sound sources connected to the table.
All input sensitivity adjustments must be done very carefully using the VU-METER and/or
headphones as a reference and avoiding that all the red LEDS of the VU-METER light up, otherwise
input could be clipped (Overload). MIC input gain control is located in back panel ADJ (14).

4.4. Channel equalization

The tone controls for each of the two main channels provide a +10/-30dB boost/cut at high
and low frequencies and +10/-25dB at the mid range. This great attenuation range is specially
indicated for the famous "kill" effect, which cuts the band over which it performs. Following
indications of experienced DJs, we have arrayed the control-knobs of the EQ section horizontally.
This placement enables a more comfortable area to work with.
MICRO channel has two band (bass, treble) tone control.
ATTENTION: Use equalization carefully, by boosting too much the low frequency range,
you can induce an excessive displacement of the speakers membrane.
4.5. Genuine ECLER Faders and Crossfader
The HAK310 uses a new generation of ECLER faders / crossfader featuring an improved
precision and very smooth movement, a very fast cut-in-time, and extra long life performance tested
up to 4.000.000 operations when combined to the ECLER VCA system (VCA=Voltage Controlled
Amplifier). In addition to its extremely high performance, the HAK310 Crossfader system features a
SHAPE Adjustment and a REVERSE Function. The SHAPE Adjustment knob allows you to "tune"
the fade curve of your crossfader from "Soft" (Mixing) to "Sharp" (Scratching).
