I'm new to the forum and this is my first post. Looks like a great forum. I recently purchased the vintage Pioneer SF-850 electronic crossover and I haven't had any luck in locating an operating manual. I'm willing to pay for a copy if anyone in the forum has this manual. I'm excited to get it hooked up, but I really need the manual before I begin. This is a professional grade active crossover. Thanks so much and Good Listening
