MAESTRO PHASER SERVICE MANUAL ocr

TECHNICAL PRICE 5250 Buffalo, NY. 14225 NORLIN MUSIC, INC INTRODUCTION Input Buffer and Summing Amplifier In the phasing mode, the input signal from This manual provides servicing and parts infor­ AXE jack J1 is coupled to input buffer IC1A convert­ mation for Maestro Model MP-1 Phaser, manufactured ing the sourced high input impedance to a low output by Norlin Music, Inc., 2500 Walden Avenue, Buffalo, impedance for driving summing amplifier IC1B. IC1B New York 14225. The Maestro Phaser generates inverts the signal, adds a gain of 1.4 and sums the standard phasing effects for guitar, bass and other output signal from BALLS control R35 with the elec-troacoustical music signals. Specifications for the input signal. The output of summing amplifier IC1B Maestro Phaser include: drives the phase shift chain. Input Impedance.......................1 megohm Six Stage Phase Shift Chain Maximum Re
