All the components required to record an audio signal are present on the Channel Strip. The 512c Mic Preamplifier, known for its extra Mic, Line, or Instrument input switching, is where it all begins. The completely adjustable 527 multi-mode compressor comes next. Your track receives the “in-your-face” punch that has made the unique THRUST® circuit in the 527 an award-winning circuit thanks to its use. The 550A three-band Equalizer with its switchable frequencies and 12dB of boost or cut is also featured in The Channel Strip. It is arguably the most well-known and beloved API EQ of all time. The high and low frequency bands on the 550A may be independently altered to function as shelving EQs, and the “B.P. Filter” switch inserts a bandpass filter that ranges from 50Hz to 15KHz.
