NOTES
:
1. All resistors1/10 Watt, 1%, 0805 unless otherwise speci-
fied.
2. Electrolytic capacitors shown in µF, ±10%, 50V or more, un-
less otherwise specified.
3. The elements U1E and U2C designate Power (+Vcc) and
Ground Terminals only the corresponding ICs.
4. The following symbols denote:
5. All voltages measured with a meter or oscilliscope having 10
megaohm or greater input impedance with preamp input driv-
en by a 0.1 Vrms, 1kHz signal through the test circuit shown
below. A Shure M367 mixer or equivalent, with 48 V phantom
power switched on, supplies the required power and load to
the preamp. Values shown may vary +/– 20%.
6. Standard symbols indicate voltages for mic on. Symbols with
dark edges indicate voltages for mic off (see note 4). Note: Mic
is truned off by holding the membrane switch closed, shorting
J4.
