Page 4: Circuit Description
KXR 200 CIRCUIT DESCRIPTION PREAMPLIFIER Input channels 1 thru 3 will accept a balanced or unbalanced signal via a ¼” phone jack. Resistors R1 & R2 are precision 1% parts which maximize the Common Mode Rejection of the first opamp stage U1A.U1A provides a gain of 1, and rolls off high frequencies above 87kHz. - Page 5 KXR 200 DELTACOMP (CONT) current controls the output amplitude of U2. The inverted signal from U2 mixes with the input to U1B providing cancellation which reduces the input to the power amplifier. This prevents the amplifier from clipping. When the output of the power amplifier is reduced, the output of U1A toggles back to +15dvc.
