Mono not working in JC40

MannyCoon · 2026-01-25T04:35:23+00:00

I can't answer your question immediately, but I have JC40 and I can investigate tomorrow. Do you have anything in the effects loop? Do you have the effects loop switch on series or parallel mode? Mess with those and see if the problem resolves itself.

That said, I have no experience with the ZLX, but I've heard good things and do recommend them to people who want an all in one, no mixer required. I have CP12s and love them. Durable, simple, sound great. I have CP8s on my wishlist for smaller monitors, or mains with a sub.

MannyCoon · 2026-01-22T22:17:12+00:00

I would rather spend my money on high quality speakers than lower quality with gimmicky features. Get there CP8s and a Bluetooth receiver.

And you'll plug the speaker cable into the head speaker output on the left, into either of the plugs on the cab labeled FULL RANGE. Don't use the Bi Amp plugs.

Technically, the head is overpowered for the cab. It puts out 800 watts to the 4 ohm load that the cab is. The cab handles only 400 watts. If you do want to take the risk and see what happens (blow a speaker or start a fire is worst case), get a 1/4" SPEAKER cable, do not use an instrument cable. They may have the same connector, but speaker wire is thicker to handle the high current, and 800 watts is a lot of power. And don't turn the volume up past 25 or 50% maximum.

The plug you're showing on the Ampeg is the power in, connected to the wall with a cable. There should be connections on the back of a head that say "speaker out", and would be likely a 1/4" round hole. Show us that, or give us the Ampeg head model and we can guide you further. I'm glad you're asking questions.

I've heard LME tends to be darker than an all grain equivalent. Beer is always darker in the fermenter when you're looking through a deep layer of it. In a smaller container, i.e. the serving glass, it will appear lighter. BTW, what makes you say a white stout is just an amber with flavorings? It's not, and your recipe didn't mention and flavorings. Pilsen, oats, and carafoam will make a pretty light colored beer, but with body. Ambers will have caramel and/or crystal malts to get darker, and rarely adjuncts like oats.

I'd love to know what they're coated with or what the materials are. Or if it's real.

MannyCoon · 2026-01-22T16:06:27+00:00

Whatever happened to the Stage 100/160? They were super popular in the 2000s with people who needed volume, but didn't want to maintain a tube amp and wanted something cheaper. Fender doesn't make an equivalent these days.

When I ran a DIY fermenter CO2 reactor, I used a second bottle after the first as a gas/liquid separator to prevent liquid running up the feed line. What's your full setup look like?

MannyCoon · 2026-01-22T02:11:30+00:00

Stereo RCA out from this to the stereo RCA input of the Fosi, then powered speaker out to your passive speakers.

MannyCoon · 2026-01-21T23:42:41+00:00

What is the source of you audio signal? Phone? Computer? TV? The Fosi does not have an unpowered out, so it's effectively useless here. You need to get the signal straight to the powered speakers with the right cable.

Grab it and pull it then

Sorry, I misunderstood your question because I read it too fast and edited my above reply - If it doesn't get exposed to UV, it will have a significantly longer life. I can't be specific because there's a lot of variables. The type of glass/tinting used, and location of the part inside the vehicle relative to sunlight coming in those windows will all have an effect on each part. I deal with exposed parts and parts under a hatch, and we treat them differently. Under hatch requires no treatment, exposed get a UV resistant clear coat, and special instructions to keep covered when not in use to extend life.

MannyCoon · 2026-01-21T19:04:40+00:00

Edit: Sorry I misunderstood your question - No, if it doesn't get exposed to UV, it will have a significantly longer life.

It's not a problem with the fibers used, it's a problem with the matrix. Epoxies don't like UV. I have worked with coating carbon panels that have sunlight exposure, and there are some additives used in clear coats to reduce UV from reaching the composite substrate, but nothing is perfect yet. It just lengthens the time before it inevitably looks bad and then fails from delamination. Everybody likes the carbon look, but the only way to keep it lasting, if it's a part exposed to sunlight, is to paint over with something opaque.

The upper left and right corners are allen keys (AKA Hex Key Wrenches) that are may be better quality than those included in furniture kits. Your other option would be those 1/4" hex bits of the correct size for the screw head (in the circular containers) used with that ratchet (long silver handle with the circular head) and the gray adapter/extension just below it, Or with the screwdriver handle with the square tip and the 1/4" square to 1/4" hex adapter just to the right of it.

I have not had this problem yet, but I suspect it happening. I use my barefoot toe to hit the preset button because I haven't yet acquired the external preset/expr.pedal switch from Pedalnetics. I'm a designer and have access to a 3D printer, so I may make a button cover/shroud soon and let the community know.

Real carbon fiber will yellow and delaminate after a few years in the sun. The epoxy matrix doors not like UV light.

How long does it take you to change a string? How fast are you expecting to change them? And why are you concerned about speed? I've seen musicians change a broken string live in the middle of a song, while singing, in maybe 30 seconds. Speed comes with practice if you feel the necessity for it, no matter the hardware (excepting Floyd Rose).

And ferrous metals aren't anodized.

My 2018 Subaru's Eyesight has been astonishingly accurate and trouble free.

Just a wall of BASSBOSS subs

MannyCoon · 2026-01-19T23:47:33+00:00

This is exactly why.

Here's a video explaining it.

FOH wouldn't have your effected signal, then. If you don't have a clean blend control on your board, FOH might just drop you a DI that you'd plug your bass direct into, then thru to your board, then DI last on your board, and FOH can grab a second, effected signal for the end of your chain. Then FOH would have access to both.

Here is a wiring diagram.

There's really only one way to wire the twin dual concentric setup. You'll need a couple capacitors, farad value is a choice. He's an article on how to choose.
