This capacitor affects attack & delay times, as well as low frequency accuracy. 4 EXP.OUTPUT 1.5 Output of the expander amplifier 5 EXP.INPUT 1.5 Expander input. Nominally signal range is 3.16mVrms to 316mVrms. Must be capacitor coupled to the signal source 6 VB 2.2 An internal reference voltage. This is an AC ground, and must be well filtered to obtain high power supply rejection and low crosstalk.
