3 Way Linkwitz-Reilly active crossover with a number of useful features including variable x/o points, baffle-step and bass-boost. Each slope is separately controlled, so the x/o point can be pulled or squeezed to compensate for driver response. This low-noise, low-distortion circuit adds no unwanted artifact to the sound and can also be used as a gain-stage. Optional Phase-delay module fits on top of the crossover as shown. Also available without optional phase delay module

Also available as a plate-amp or monobloc project with power amps and power supplies

Recommend -/+15v regulated power supply

Regulating Power Supply for use with external DC supplies like desk-top, wall-wart or laptop adaptors. Filters out noise and hash from these switch-mode supplies, providing very clean DC suitable for use with solid-state phono-stages and pre-amps. Designed to work with a 30vDC supply and provide a regulated split-rail voltage of -/+12v. These will power our solid state MM and MC phono modules as well as our active crossovers. Voltages can be changed with some component swaps.

Ready-built PCB requires connectors to be purchased separately and soldered on. See datasheet for details

Regulated Pre Amp Supply for ZinAmp Solid State Phono and Pre Amps. Split rail supply, can be set to +/-21v, +/-15v and +/-12v DC. Requires an AC transformer with dual secondaries between 12v and 30v - min 20VA.
