Limiter-Calculator

Notes on the limiter calculator & converter

All predefined values ​​above must be known.
Power amplifier: input sensitivity in volts*, power at impedance.
Speaker: The RMS load capacity.

Then you select your DSP, or enter manually
the reference point. If your limiter works in dBu, enter 0.

Finally, press “Calculate Limiter”.
In addition to some interesting values ​​for the power amplifier and speakers,
you can now read the thresholds for your limiters below.

If a peak limiter and a RMS limiter is used together in the output,
you have the choice between 100% safe (+3dB) and the usual, more dynamic +6dB.

Note: 
0dBu always corresponds to 0.775V.
Full input voltage (sensitivity) means that your power amplifier
delivers 100% power at this applied voltage (0.775V).

Reference point:
Check your data sheet for “Maximum Output Level” in dBu.
This value corresponds to 0dBfs threshold and must be entered as a reference point.

*If the input sensitivity of the power amplifier is not known,
this can be calculated based on the voltage gain or the amplification (gain) factor.
This will usually be in dB or also as a factor (multiplier).
You can use the converter to determine the desired values.

Example: 1000W at 8 ohms, 0.775V =
Voltage gain 115x or voltage gain 41.24dB
