4.5. Virtual Speaker Mode - powersoft IpalMod User Manual

15 : 4.4.9. Gate
The system is equipped with a gate output block intended to improve the overall signal-
to-noise ratio. The gate reduces the output gain for small signals interpreted as noise. The
hold time indicates how long the gain reduction occurs after the output signal falls below
the threshold. The attenuation parameter indicates the amount by which then output gain is
decreased withn respect to no attenuation. Note that the system gain changes slowly and
not abruptly so the effect is unnoticeable.
15 : 4.4.10. Voltage RMS Limiter
Set a threshold limit and the attack/release time for the average (rms) output voltage.
15 : 4.4.11. Voltage Peak/Clip Limiter
Set a threshold limit and the attack/release time for the peak output voltage. A clip limiter will be engaged.
Clip limiter can be set as flat (same clipping level per frequency) or frequency dependant (clipping level changing depending
on the thershold set) see the graph for reference.

15 : 4.5. Virtual Speaker Mode

The virtual speaker mode allows the user to enter a set of Thiele Small parameters that
describe a transducer: this can be either a physically existing loudspeaker the user would
like to emulate, or a non-existing, ideal transducer.
The DSP uses these parameters to drive the amp module so that the entire system
performs exactly as if the cabinet houses the wanted transducer.
The system automatically adapts its internal processing using information from the pres-
sure sensor to virtually reproduce the behavior of the user defined transducer. The way this
is achieved is practically user-transparent, meaning that the user can "interact" with the
system only by changing the virtual speaker's parameters and not the system's internal loop
parameters.
