NOTES:
1.
All resistors1/10 Watt, 1%, 0805 unless otherwise specified.
Electrolytic capacitors shown in µF, 10%, 50V or more, unlss otherwise specified.
2.
3.
The following symbols denote:
A.C. Voltage
D.C. Voltage
(+) / (–) indicate A.C. polarity relative to input test signal.
4.
All voltages measured with input driven by a 0.1 Vrms, 1kHz signal through the test circuit shown below.
The test circuit is powered by a standard 48V phantom power supply connected to J2, with a 1 kohm
load across J2 pins 2 and 3. A Shure M367 mixer or equivalent, with 48 V phantom power switched
on, supplies the required power and load.
