Dual-Layer Fader Strips
Dual-Layer Fader Strips
Layer Switching
The 8 channel faders, CUTs & SOLOs can control either the:
● Analogue level, of the main channel paths.
● 8 DAW fader tracks, within the DAW software.
The layer switching is handled from the Control Surface Panel:
Select DAW (it turns red) to ip all
8 Fader Strips to the DAW layer.
Deselect DAW (not illuminated) to
control the analogue layer.
When you change layer, all 8
channel faders (plus SEL, CUT &
SOLO switches) update to their
corresponding positions.
Both layers are ALWAYS active, even if the DAW is
not connected. This means that if you set an
analogue fader level, and then switch to DAW, you will still hear
the analogue channels (providing audio is present).
Therefore, take care NOT to change layer by accident - if
nothing is happening to your analogue channel level when you
move a fader, check that you are controlling the correct layer!
Channel Fader
The channel fader is a high-quality ALPS 100mm linear fader
that can control either the analogue main channel level or a
DAW fader. The fader is motorised and can automate both the
analogue level and DAW fader layers.
Fader Scale & Resolution
Please bear in mind that the scale beside the channel fader is
for analogue level indication only.
When controlling the DAW layer, the fader scale is dictated
by your software. For example, in Logic, faders can operate
to +6dBFS above unity, yet in Pro Tools it is +12dBFS. This
means that the resultant fader scale, and the resolution at the
top of the fader differs depending on the DAW.
This is a limitation of the HUI
TM
protocol.
Channel SOLO & CUT
The CUT switch mutes either the analogue
main channel or a DAW fader. It can be
automated on both analogue and DAW layers.
The CUT switch is also activated when using
solo-in-place (see below).
The SOLO switch places the channel into one
of three solo modes: AFL (after-fade listen),
PFL (pre-fade listen) or SIP (solo-in-place).
The mode is selected globally from the master
section, see page 40
You can select multiple SOLOs in all modes.
When using solo-in-place, all channels not in solo are CUT.
You can isolate a channel, so that it does not CUT in response
to other SOLOs, using the SIP SAFE function, see page 25.
When using either AFL or PFL, some of the main mix can be
“blended in” behind the solo’d channels using the SOLO IN
FRONT master control. See page 40 for details.
Analogue Level Control
The diagram below illustrates what occurs when the fader
strips are switched to the analogue channel layer:
The fader (and CUT) are not in the audio path but act as
control signals, sending D.C. control voltage changes to the
analogue “Level Control”. This applies attentuation, mute and
up to +10dB of gain to the analogue main channel path.
In addition to responding to physical fader (and CUT) moves,
the analogue level control is adjusted by:
● HUI
TM
/ MIDI automation - this allows you to automate the
faders and CUTs of the 8 analogue main channel paths.
● Global commands - for example, press UNITY (on the
Control Surface Panel) and then press a fader strip SEL
switch - the analogue level (and fader) are set to 0dB.
The components used in Control 2802 ensure a clean,
accurate and repeatable automation platform - control
resolution is very ne, and when channels are CUT, click-free
silent muting is applied.
For more on analogue fader automation, please see the
“Automation & Control Surface Manual”. For more on UNITY,
see page 25.
DAW Fader Control
When fader strips are switched to the DAW layer, their D.C.
control voltages are processed by on-board microprocessors
to output HUI
TM
control surface functionality and automation.
The microprocessors also respond to incoming mute, solo-in-
place commands, fader positions and MIDI automation.
This enables you to control DAW parameters, and write and
replay automation.
The setup and operation of the DAW layer is covered fully
in the “Automation & Control Surface Manual” which can be
