Description
Active Tone and PGA2311 based Volume Ctrl. A uC is needed to control the PGA and Relays (use of ULN2803 is recommended to avoid switching noise).
Tone-Control@100Hz ± 8,3dB
@10kHz ± 9dB
Signal source: HIFI-Raspberry_PI_DAC, measuring device: Audiointerface Swiss Sonic UA-2x2 THD@1kHz = -87dB or 0,004%
measuring device: Analog Discovery 2, Signal source: Built in AWG,
THD over the Freqency-Range from 10Hz-25kHz is below 70dB or 0,03%
(maximum achievable accuracy of the device.
Frequency Response for max, min and centre position of tone-control is shown in the figure below.
