1. Audio voltage regulator is
usually installed between the STB (KOD player) and the power amplifier.
2. The output audio frequency of KOD player or STB should be better controlled within 0.05Vp-p (or 0.2Vrms) to 5Vp-p (or 1.5Vrms); if the output audio frequency is too small, the attenuation signals will be wasted; too small volume of song list will also waste the attenuation signals.
3. The power amplifier should have remote or wire-driven function, so it can be used to control the volume.
