Question about Pioneer Car Audio & Video
Can I get a wiring diagram for the pioneer CD 635 active crossover? I am getting no sound except noise. at the input terminals I am getting a voltage reading of 6V.So I am guessing there is a problem with the input stage IC. Can you help?
a 6ya expert can help you resolve that issue over the phone in a minute or two.

It doesn't work at all
If your dishwasher doesn't work at all, check these:
Power from the house Is there power getting to the dishwasher? This can be difficult to test, because dishwashers are usually wired directly to an electrical circuit, rather than plugged into the wall. But at least check for a blown fuse or a tripped circuit breaker.
Door switch The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.
Wiring Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.
Timer or selector switch Although it's uncommon, the timer or the selector switch may be defective. If so, you need to replace the defective part, because neither of these can be repaired.

Hi Big John
This is a nice reference series amp with a decent phono preamp stage. It is unusual to see a phono stage get damaged in this way.... but Murphy's law tells us "If it can be blown up, then someone will do it". I recommend that you do fix it. First up, perhaps check the settings for the preamp on the rear of the amp(from recollection). Be sure that you have it in moving magnet (mm) mode if you are using a MM cartridge.
Although its been a few years, My recollection is that there is a separate power supply for the phono preamp, with maybe even power regulators on on the actual preamp board. First check would be here to see if both DC rails are present for the phono Preamp stages. Most common failure here is heat stressed cracked/dry solder joints.
You need a good HiFi/Audio tech to have a look at it for you if the problems run deeper than DC supply for the preamp. Good luck. A FixYa rating is a great reward for my time to address your problem. Cheers

Passive crossovers are easy to install. By definition, the only type of connections they require are to your speaker line. They typically get installed between the end of the speaker wire and the speaker. Connection should be fairly simple, just like hooking up the speaker itself.
Now F-Mod crossovers modify the audio signal before it is amplified. They accept the patch cord from your receiver on one end, and then plug directly into the preamp inputs on your amplifier. They are also easy to install, and don't require additional wiring.
An active crossover requires a little more work. You have
to connect 12-volt power, ground, and a turn-on lead. The active
crossover gets installed between your receiver and your amplifier. A lot of
active crossovers have both speaker-level and preamp inputs, so they
can usually work with either type of connection. The outputs will be
preamp connections to your amplifier. Hope that helps.
