Use any volume control on the g\x\fs20 uitar to control input level.\par \ql \x\fs20 \par \ql \x\fs20 A potential divider creates a phantom 0v rail for the non-in\x\fs20 verting input to the op-amps. This eliminates the need for a \x\fs20 split power supply. The current consumption is very low, arou\x\fs20 nd 3mA so will run from a PP3 battery for some time.\par \ql \x\fs20 \par \ql \x\fs20 IC1 is an inverting amplifier with a gain of around -100. Thi\x\fs20 s will deliver around 500mV from a 5mV signal. VR1controls th\x\fs20 e gain of the amplifier which varies from 1 to 50. At minimum\x\fs20 gain the signal for the most part remains unaffected. As the\x\fs20 gain is increased more of the signal will be clipped but the\x\fs20 output should not rise above 1.5v peak to peak. The input sh\x\fs20 ould be a between 2-5mV. Any more and the clipping will be mo\x\fs20 re severe even at minimum setting.\par \ql \x\fs20 \par \ql \x\fs20 } }"e" `=S @ @ @ @ @ " jj"jj y""~" z"d@  C[{\rtf1\ansi\deff0\deftab254{\fonttbl{\f0\fnil\fcharset0 Arial;}}{\pard\ql \x\fs20 Input} }d`=\{\rtf1\ansi\deff0\deftab254{\fonttbl{\f0\fnil\fcharset0 Arial;}}{\pard\ql \x\fs20 Output} }"( g"Q f"Qx9"j"j  y"I@47   @ h. h."x (+"j" j g""cq( "j"j  e"""b b"""y""[(iy"e"N bx @ @ @ @ @ "p$@pPOWER4:0*m0*m0*m"Nj"N j "y"""  f"""cqz(#  `{TL072NpbNpbNNNz"" <(J" C C z"#"`7`NCLIPPING100K1.00iد "H>~"C@~H@~H Cz" `s1M pp " x z("~   z"" x ( ""  e""~>_B_@_@_#" x 8XHf"~>_@_"~"$ $" x "^b~"`` #"Xh( "~b"`  " ~2N&'2'N'y"z""!^K&'`'K'z"z"""Kg>~'g@~K@~K'z""DR."#K&'K''#"$^"``   #"%~""   "&"$B_@_@_@_ C $ C $   #"'H"C"C  CH C""AO<(J"(,HC"CH C, C#"z(z(")^B_"@_@_ ` #@ @MbP?"@
