4.6. Cutter / Transformer 
 

Input selector Switches (29) found inside the HAK310 are high quality components which 

have proven through the years their excellence due to their great precision and endurance. Using 
them a cut switches, you can perform (similar to a "hard" set fader) total cuts to the respective 
channel. If this cut-off is done rhythmically to the beat, you will achieve the famous Transform effect. 

The direction of the Cut switch can be customized individually (8 positions) after 

unscrewing the front cover (Sec 4.7). 
 
4.7. Replaceable components (Faders, Crossfader, Switches) 
 

In addition to an internally modular assembly system, the HAK have mounted in an 

easy-to-replace module all the main components that suffer an especially high wear: the two main 
faders, the crossfader and the cut switches. All these components can be substituted by just using a 
screwdriver because they have multipin connectors. 

 
In order to replace any of the elements, proceed as follows: 

1. Remove the fader buttons from the HAKs silver-plated surface. 
2. Unscrew the module from the front panel. 
3. Remove it from its fitting hole. 
4. Remove the screws which correspond to the element you wish to exchange. 
5. Unplug the multipin connectors. 
6. Replace it with a new one. 
7. Plug in the multipin that you unplugged in step 5. 
8. Gently put the front panel back in its place. 
9. Screw it tight. 
10. Put the fader buttons back on its place. 

 
ATTENTION: Always use original ECLER GENUINE SPARE PARTS for your HAK310. 
 
4.8 Outputs 
 

Headphones: in order to obtain a high performance, these should be of the high 

impedance type (200-600



). Plug them to the PHONES output (34), in the front panel, by means of 

a standard stereo jack. Sleeve is Ground, Ring is Right Channel and Tip is Left Channel. 

The HAK310 has two main outputs OUT1 (8-9), balanced ¼” TRS Jack, 0dB on 600



 and 

RCA (10) connectors 0dB on 1k



. OUT2 (7) RCA, +6dB on 1k



 with their own volume control by 

using a rotary knob to adjust the output signal. Small plastic black Jumpers (A set of 5 jumpers is 
delivered with the HAK310) can internally adjust (Fig 2) main outputs to +6dBV (2V) or 0dBV (1V). 

ATTENTION: You must be careful when setting up the general output level of the mixer. 

The "clip" display of the connected power amplifiers must never remain permanently lightened up, 
but do it occasionally by following the rhythm of the bass signals that are being played. 

CAUTION: Output level changes must be performed by a qualified technician. 
The HAK310 mixer has a REC (11) output of 0dBV nominal on 10k
