Section 4: Stereo Mode
Although Orfeusz206 is a spatial sound unit, it also provides an alternate Stereo Mode useful for
managing speakers in a conventional stereo set-up.
Stereo Mode comprises 3 main modules: Input Mixer, Output Mixer and System Configurators. We call
here system any combination of filters/eq/gains/delays required to perform a full crossover unit.
This section describes successively the various modules, and then illustrates with general examples how
Orfeusz206 crossover systems allow for extra-fast set-up.
Input Mixer
The block diagram of the Input Mixer is shown below, and consists of identical gains, delays and
graphic equalizers available on each section. Inputs 1 and 2 are summed to provide signal 'mix',
appropriate for feeding subwoofers.

Here are operation details about the Input Mixer. Please refer to the screenshot on next page to locate
corresponding controls.
Level-meters show signal level in dBFS at A/D conversion stage.
Inputs 1 and 2 are equipped with a soft-mute button.
When adjusting gain, make sure not to clip signals. A clipping led is available in gain each
section.
Delay values can be either typed in the edit boxes, or set with the jog-dial, which has gross and
fine adjustment knobs.
To switch on graphic EQs, click the corresponding 'On' switch. Click again to switch off
(bypass).
Graphic EQs may be linked ('Link' button): the changes made to one section are duplicated in the
two other sections.
EQs' filters bandwidth is adjustable (narrow, medium or large).
You can load and save EQ presets ('Preset' button). For a flat correcting curve, load the flat
factory preset.
EQ output level is adjustable from –12 dB to +12 dB.
If the EQ section is clipping (red led), lower the input gain in that same section.
To set an EQ slider back to 0, double-click on it.
