Sending to external effects units FX Send/Return
The 4 channels from the GOA4D are equipped with potentiometers (8) that allow sending the signal to an external
effects unit, sampler, etc. These potentiometers allow to precisely adjusting the signal level sent from each
channel.
The FX SEND output (41) has to be connected to the effects processor's input and its output to the RETURN input
(42) or any LINE input (36).
This signal send can be configured either PRE or POST fader with the PRE/POST toggle switch (9), so that the
level is affected or not by the channel fader.
The GOA4D also wears a general FX SEND controller (17), which adds the four channels, a general FX RETURN
controller (15) and a controller for the FX RETURN monitoring signal, FX CUE (16).
Faders
®
The GOA4D is equipped with the new generation of AUDIOPHONY 60mm faders (11) which are precise,
extremely soft and their features withstand over 4.000.000 manipulations, thanks to the VCA system (VCA: Voltage
Controlled Amplifier)
The usage of VCA technology allows the modification of the fader's behavior. On the frontal panel you will find the
FADER SHAPE potentiometer (18), which allows adjusting the fader's curve so that the volume is proportionally
distributed on the fader's range or that it appears suddenly.
Crossfader
Each channel can be assigned to the crossfader (12) using the A/OFF/B switch (10). The crossfader allows melting
the signals assigned to its sides. If the switch is in position A or B, the channel is assigned to one or the other side
of the crossfader. The OFF position disables the crossfader function for this channel.
The GOA4D's crossfader includes a range of controls which allow adjusting its behavior and make it a really
accurate tool. The SHAPE control (19) allows you to precisely adjust the skew angle of the crossfader's curve.
Turning the controller completely to the left, the two songs will be melt softly. The crossfader's curve raises when
turning the controller to the right. Moving the controller completely to the right, the signal will enter suddenly with
just a short movement of the crossfader, which is a very suitable feature for scratching techniques.
The REVERSE switch (20) inverts the crossfader's direction. Depending on the selected direction, it is possible to
perform "cuts" as well as "transforms" moving the crossfader into the same direction.
The electronically correction for the CUT IN (21) is only effective if the GOA4D has been equipped with the optional
ETERNAL crossfader (ref. XF ETERNAL). If it only wears the standard crossfader, the CUT IN potentiometer must
remain in the OFF position. The CUT IN is the existing distance between the physical end of the crossfader and the
entering point of the signal. The position with the shortest CUT IN provides a nearly instantaneous signal cut. To
find this position the fader has to be set to an end and the CUT IN potentiometer must be turned rightwards until a
musical signal can be heard. To enlarge the CUT IN time, turn the potentiometer to the left.
If you want to extend the life time of your crossfader, the GOA4D allows the installation of the awarded ETERNAL
crossfader. This inductive crossfader technology is based on a magnetic control system and is completely contact
free. The combination of this technology with an exclusive, mechanical sliding system provides a soft handling and
one of the most precise crossfaders available these days. The inductive ETERNAL crossfader has been specially
designed to execute extreme turntablism techniques, which require an extremely soft and fast movement of the
crossfader.
