AUX (9) Auxiliary Send
The PHONO/LINE module of the SCLAT 200vs features a stereo bus for auxiliary sends,
AUX. This send is by default configured as post-fader, i.e. the position of the channel FADER (16)
affects the signal level sent to the AUX SND bus.
This behaviour can be internally modified and converted to pre-fader by just repositioning the
jumpers indicated in figure 1.
ATTENTION: The modification of the pre-fader or post-fader setting must be carried out by
a qualified technician.
PFL (17) Pre-Fader Listening button
Activates the visual monitoring on VU 1 and audio monitoring of the input signal on the
corresponding channel. See paragraphs: Visual and audio monitoring in the MASTER Module
chapter.
CUT (18) Switch
Cuts the channel signal just before reaching the fader, letting you execute any gain or tone
adjustment through the monitoring system (VU METER or Headphones). In order to maximize the
signal to noise ratio of the mixer, it's recommended to mute all unused channels. Unmuting a channel
with a raised fader instantly activates the channel. A visual indication lights up when the channel is
muted.
XFA (19), XFB (20) Crossfader assignment buttons
The MASTER module of the SCLAT 200vs features a horizontally positioned fader. This
device - called STUDIO VCA XF - lets you make a transition between any channel signals in a very
easy way.
The Studio VCA (Voltage Controlled Amplifier) is an electronic gain circuit, which is used to
indirectly control the level of an audio signal. The crossfader generates a continuous voltage which is
used to remotely control the gain of an intermediate amplifier. Advantages of this concept are that
unwanted noise is eliminated, as the signal does not pass through the crossfader, and the useful life
of the crossfader is greatly extended. The SCLAT uses studio-quality VCA circuits which offer better
Distortion and Signal to Noise Ratio characteristics than other VCAs found in DJ mixers.
The two push-button found below the MUTE button let you assign the current channel either
to the A Crossfader channel (XFA) or to the B Crossfader channel (XFB). A visual indication shows if
the current module is assigned to channel A or B of the crossfader. If a module is not assigned to any
crossfader channel, the signal will be sent directly to the main mix bus. if both push-buttons are
depressed, the module will be assigned to XFA
PEAK (14) and SP (15) Indicators
The PEAK indicator lights up when signal clipping is imminent. The signal is not yet clipped
but the real clipping threshold (saturation) is almost reached. The PEAK indication may sporadically
light up to the rhythm of the music (bass frequencies) or during a "shout". It should under any
circumstances keep lit permanently. The peak indicator activates at +10dB above the nominal input
level.
The SP (Signal Present) indicator directly monitors the input signal before the GAIN control.
Its threshold is set at -40dB. This indication is an excellent quick reference for verifying that the signal
source is actually working.
Channel FADER (16)
The SCLAT 200vs only employs high quality professional faders.
