DSP CONTROLS
A - Green LED 'sig' (signal): it lights up when an input signal is detected.
B - Red LED 'clip': it lights up when a clipping (excess of signal level) is
detected in the input stage of the internal DSP. If this indicator flashes
frequently or is always on, reduce the input level, acting on the volume
control (6) or on the mixer's output gain control.
C - Yellow LED 'thw' (thermal warning): when lit, it indicates that the
temperature of the internal power amplifiers is close to, or higher than,
the attention threshold: the internal microprocessor is analyzing the avail-
able energy. It is a normal behavior for this LED to flash even in absence
of input signal. For a correct operation, check periodically (monthly) the
rear panel's ventilation grills and verify that they are free of obstructions.
Also check that the speaker's temperature is not too high due to proximity
to heat sources or because subjected to direct radiation from the sun.
D - Red LED 'prot' (protection): this led indicates the intervention of the
protection circuit of the internal power amplifiers. The reason may be an
excess in terms of temperature, of output current or a fluctuation in mains
supply value (lighting strikes or brown outs). The LED comes on even if
the speaker has been muted by remote control, via the RAConLS software
program (refer to par. 5.3).
P1 - P2 - P3 - P4 - P0: these LEDs show the active Preset.
P1 - P2 - P3 - P4 are the factory (default) preset, P0 is the user preset.
The four LEDs P1 - P2 - P3 - P4 come on when the speaker has been muted
by remote control (refer to par. 5.3).-
UP - DOWN: these pushbuttons allow for preset selection.
For a description of the presets and how to load them refer to par. 4.2.
E - Green 'Sub 1' and 'Sub 2' LEDs: when on, they indicate that the SUB
OUT output is active and what type of sub-woofer drive signal has been
selected (refer to par. 4.2).
