Excessive DC and low frequency content in audio playback signal can damage loudspeakers. The TAS2562 employs a high-pass filter (HPF) to prevent this from occurring for the PCM playback path. The HPF can be disabled using register HPF_EN. The HPF Bi-Quad filter coefficients can be changed from the default 2 Hz using the HPFC_N0, HPFC_N1, HPFC_D1 registers using the equation [N, D] = butter(1, fc/(fs/2), 'high'); round(N(0)*2^31);. These coefficients should be calculated and set using PurePath™ Console 3 Software.
