SPEAKER PRESET Processing Features SPEAKER PRESET Processing Features
SPEAKER PRESETS are channel-based features that can be loaded onto individual channels using preset files
that can be made in the preset creator or provided by OEM manufacturers. The user doesn't have direct access
to these controls but can choose to load or clear the speaker preset from a channel. A speaker preset can con-
tain the following features:
Gain Controls the amout of gain, ranging from -80 dB to 15 dB.
Polarity Flips the polarity 180°.
Speaker Delay Set a delay time up to 30 ms.
Note: the speaker delay is added on top of the combined 250 ms USER/GROUP delay.
12 Band PEQ 12 bands of EQ with a choice of 16 different filter types per band including all-pass filters.
IIR HPF X-Over infinite impulse response high-pass filter, with a choice of 19 filter variations.
IIR LPF X-Over infinite impulse response low-pass filter, with a choice of 19 filter variations.
FIR Filter Allows to load a FIR filter file with 768 taps.
RMS Limiter RMS limiter with adjustable threshold, attack and release times.
Peak Limiter Peak limiter with adjustable threshold and release time.
Note: these are the last limiters at the end of the signal chain.
The chart below illustrates the most extensive signal path possible for a single channel, utilizing the
complete processing capability of the CloudPower™️. Note that the group blocks consist of 6 layers,
indicating that a single channel can undergo processing by all six groups simultaneously. The VU
meters, which are visable in the web interface and on the front panel OLED display, are measured at
the end of the signal path, just prior to the 70/100V high-pass-filter which closes the processing chain.
