The Coil Audio CA-286S is a 2U mic preamp standalone version of the CA-286 PS6 tube mic/line amplifier, inspired by a classic European two-stage circuit The Coil Audio CA-286S uses the exact same European style circuit as the CA-286 PS6 and delivers the same Hi-Fi tone and rich midrange. It uses Coil Audio’s own CT110HN input and CT-10 output transformers as well as NOS Octal tubes, resistors and high-quality capacitors. The input section includes a four-position switch which provides various 150/250Ohms mic pads from 0, -6dB, 12dB, 19dB which also affect the line-level amplification when engaged. Negative Feedback is used to modify the frequency response by increasing the amount of negative feedback into the circuit. A Low switch works in conjunction with the NF switch to boost or reduce the amount of low-frequency energy. Finally, the output control knob is placed between the 1st and second stage EF86 tubes and id used to set the final output.
