Configuration notes for the DSP sound effects
The HELIX DSP MINI MK2 offers unique DSP
sound effects like "Augmented Bass Processing",
" StageXpander", "RealCenter" and many more. In
order to enjoy all DSP sound effects, specific set-
tings have to be made in the hardware and software
configuration.
Notes for Center Processing with its functions
RealCenter and ClarityXpander
If you want to use the RealCenter and ClarityXpander
function for a center speaker follow the subsequent
steps:
1. You need at least one left and one right analog or
digital input signal.
2. Open the IO menu of the DSP PC-Tool. Route the
left and the right analog or digital input signal (no
sum signal) to the output channels A and B (see
example in the following image). It does not mat-
ter, if the output channels are defined as front,
rear or center channel.
Note: You will achieve the best performance if
the input signal is a fullrange signal.
3. Generate a summation signal from the same two
input signals and route this to the output chan-
nel E. This channel should be defined as "Center
Full".
4. Repeat steps two and three for all routing matri-
ces that are used.
5. Now switch to the FX menu and activate the de-
sired sound effect by placing a tick.
Note: The Center Processing affects only the out-
put channel E.
Notes for StageXpander and ClarityXpander
function
Normally, the settings of the StageXpander and
Front ClarityXpander only affect the output chan-
nels A and B. If you want to drive a fully active
2-way front system, it is necessary that these sound
features affect all four output channels A to D.
Therefore, you have to activate the routing in the
FX menu under "Front processing" by activating the
"Link to C+D" function.
Notes for Augmented Bass Processing with
its functions Dynamic Bass Enhancement and
SubXpander
There are as well some adjustments necessary if
the Augmented Bass Processing and its sound ef-
fects shall be used.
1. You need at least one left and one right analog or
digital input signal.
Note: If you use the analog input then you
achieve the best performance if all four input
signals are used.
2. Open the IO menu in the DSP PC-Tool. Generate
a summation signal from all left and right analog
or digital input signals and route this to output
channel F.
3. Repeat the routing for all routing matrices used.
4. Now switch to the FX menu and activate the de-
sired sound effect by placing a tick.
Note: The Augmented Bass Processing affects only
the output channel F.
