Where on a 16:2 allen heath wizard would you hook
The answer all depends on what you want to achieve.
- If you just want to enhance the sound of 1 or 2 instruments / voices you could take a signal out from an individual channel on your mixer using the direct out and insert jack sockets on that channel however this may make it difficult to control in conjunction with teh E.Q. controls on that channel as the Sonic Enhancer would be pre-fade and pre E.Q.
- Alternatively you could send several mixer channels of your choice through the Sonic by using one of the sub-mix outputs to give a feed to the Sonic, returning it to the main mix either via a couple of spare channels, or the paired stereo inputs that are only routed to the main outputs.
- Thirdly you could use one of the auxiliary sends to allocate different levels of signal from any number of channels to the Sonic. These are normally used to supply a separate mix to on-stage fold-back systems, monitors etc. Here I would use one of the 2 post fade ones rather than the pre-fade - to avoid negating what you have set on the main mixer e-q (tone controls)/. One advantage of this option is that it allows you to only enhance part of the signal from a particular channel and to allow part to bypass the Sonic without enhancement. I think that this would be my preferred option unless all the auxiliary feeds are needed for other purposes.
- Lastly you could just put the Sonic on the main outputs of the mixer. This would mean that the same level of enhancement would be applied to the whole mix. As the Sonic Enhancer only has unbalanced (mono) jack sockets this later option does reduce the likelihood of you introducing unwanted radio interference to the system, compared to putting it at an earlier stage in the mix because, as the Sonic is unbalanced, everything else after it in the mix chain will also be unbalanced.

Above is your user manual below is a service and repair manual.
Indeed i would suspect something around your Final Output semiconductors, and any associated resistors?
You really must obtain a service manual, here there are the troubleshooting steps required to isolate and hopefully allow repair of your unit.
Look for any discolored components etc, check if any are overly hot... use a temperature probe on suspected components. Freeze spray may also be useful in diagnosis.
Use your eyes & nose to isolate the bad burnt overheated components, I sometimes use a straw up a nostril and selectively go over suspect parts, and "Sniff" to try and detect the overheated smell... it works.
Above is your tech support link, contact them for any info you require.

Zoom MRS 1608 will not power on
I suggest checking to make sure those 2 units can actually use the same adapter and also check the polarity on both to see if they are the same. Most stompbox stuff usually has negative on the center of the socket, instead of positive like other devices. If I spend a little time I could find the manuals and find out for myself but, this was my logical "top of my mind" kind of advice. Those values (volts,mA, and polarity) must be known in order to help you further. I believe it will be 9v, a few 100 mA's, and negative in the center on both but, not sure.

Baldwin pianovelle ps2500 my piano turns on but speakers don't sound can someone give a hint to solve this problem
So I got a used one of these for free because it had the same issue.
I read about battery failure, so I opened up the piano and sure enough the battery had corroded. I also read that the battery is only necessary for the memory feature, which I don’t care too much about. I pulled out the board (super easy to do, no screws or anything, it just pops out) and took it a local electronics/tv repair guy. In about a half hour he took off the battery, fixed a bad trace on the board with a quick solder, and handed it back. $40.
Plugged it back in, bam works like a charm.
As long as there wasn’t too much damage from corrosion, a repair guy should easily be able to do what I described.
I hope this solves your (and anyone else’s) problem!

I need to know the value of the Resistor "R1" in
Let us use a bit of logic to resolve this... I have an Axiom but it would be a lot of screws to take out to get to the part... so let us think about this. The resistor value starts with a "1" and we know it is 5% tolerance (gold). we know the resistor burnt up with likely 5 volts on it... Value could be 1000 ohms, however the voltages present (12 volts max) would NOT have burned up a resistor of 1000 ohms. The USB area is mostly 5 volts and across 100 ohms is only a quarter watt... not enough to really burn up a resistor... First thing is to MEASURE that the resistor s open... in spite of being burned, it MAY still be OK... these resistors now usually either open or remain close to their value. The resistor ALSO may be a fusible resistor intended to act as a fuse... Is the resistor open or not? is it near a resistance with a "1" as the first digit? If it is not open I suspect it is not all of the problem. In that case, look for a burned circuit trace on the board. If it is open, then MEASURE the voltage across the resistor with the power applied. If you find 5 volts, then it MIGHT be a 10 ohm used to limit the USB current to 500ma. Get back to me with your findings... I have unraveled many of these things...

Yamaha P-250 Stage Piano won't boot up...
Yamaha pianos go through a self test on start up. This could indicate a problem on the main motherboard.
Try a hard reset.
Hold down top C key while turning on.
Wait for it to start up, if it still freezes its time to take it to the repair shop.
