1.0 Overview 1.1 History of the API Equalizer The lineage of the 5500 circuit can be traced back to the original 550 equalizer designed by Saul Walker, the founder of Automated Processes, Inc. That three band EQ was originally used in the earliest API consoles built in the 1960s. Engineers were immediately captivated by its fully reciprocal boost/cut characteristic and its proportional Q design, one of API’s... -

1.6 Power Mute and Bypass The 5500 features a true hard-wire bypass. In this mode, the output connector is wired directly to the input. Shortly after power is first applied, or immediately after it is lost, a special circuit forces this mode, so signal is never lost and power thumps are never heard. -

+24dBu, but another API device could distort any input transformer since it is capable of an undistorted +30dBu output. Since API equipment is capable of signal voltages that are typically twice as large as most professional equipment, it is possible that the input transformer will experience some distortion in the low frequencies when fed signals beyond +24dBu. -
