Coil Audio CA-286S
The CA-286S single channel preamplifier is a standalone single channel 2U version of the larger CA-286 PS6 preamp module but with onboard power and a more streamlined control layout. It boasts the exact same European style circuit, tubes, transformers, and high-end components as its PS6 sibling but with a more elegant and user-friendly design. Simply put - The CA-286S is the easiest way to get those Hi-Fidelity EF86 tube tones into your studio.
The (INPUT) pad section contains a phase reverse switch, and a 6 position pad network. The first four positions are various 150/250 ohm mic pads; -6db, -12db, and -19db. The last two, L1 and L2, allow line-level signals providing tone-shaping capabilities while mixing from your DAW, tape machine, other line level devices – including other preamps.
The (NF) control varies the amount of negative feedback present in the circuit. Counter-clockwise brightens and moves the sound forward while raising harmonics and sensitivity. Turning it clockwise increases negative feedback, producing a darker tone with a smooth, dampened harmonic structure.
The (HI) switch transitions from the natural openness of the tubes, to a gentle filtering of upper frequencies.
The (LOW) switch reacts with the NF, boosting or cutting low frequency while moving the low end from front to back in the sound stage.
The (Output) control knob is placed between the 1st and 2nd stage EF86 tubes and sets the final output level.
