4.5.- Removeable / Exchangeable module (Faders, Crossfader with VCA, PUNCH, SHAPE)
The addition of the Voltage Controlled Amplification (VCA) control to the fineness,
precision and mechanical strength of the crossfader has resulted in an operating life greater than
300.000 operations. That means that the SMAC crossfader operating life is 30 times greater than a
high quality mechanical crossfader.
Once the operating life of the crossfader, SHAPE, PUNCH switches or faders has ended,
they can be easily changed proceeding as follows:
1.- Remove external screws of the module.
2.- Remove the module.
3.- Disconnect the multipin connectors.
4.- Remove the screws of the element to be replaced.
5.- Replace the desired element.
6.- Fix the new element to the module.
7.- Connect the multipin connectors.
8.- Place the module and fix the screws.
Always use original ECLER GENUINE SPARE PARTS for your SMAC
4.6. External effect output, EFF
Each mixing channel of the SMAC PRO40 are provided with a rotatory potentiometer (8) to
send the signal to an external effect unit: sampler, rever,... The potentiometer controls the signal
level send to the external unit. The EFF output (27) must be connected to the input of the effect unit
and the output of the effect unit can be connected to the MIX input (26) or to a LINE input. The MIX
input is a direct access to the main mix bus and hence, no control is possible. But if a LINE input is
used, the signal can be processed as a normal sound source.
4.7. Crossfader assignement
The SMAC PRO40 has a crossfader with VCA and the adjacent channels (Channel 2 and
Channel 3) are permanently assigned to it. The remaining channels, can be assigned to any of the
crossfader extrems (A-B) by means of the 3-position lever switch (10). This switch can also bypass
the crossfader and send the signal directly to the mix bus.
4.8. Crossfader curve adjust:
Thanks to the VCA concept, it's now possible to modify the gain/attenuation behaviour of
the crossfader. The SMAC PRO40 provides this feature, enabling you to control the fade-in and
fade-out characteristics of the crossfader. The Crossfader knob XF SHAPE (12) at the housings
frontplate let you adjust the response curve from soft to hard independently so that you could
perform from sharp Scratch to smooth House techniques.
