I have the epiphone dr 500mce and it has started to hum when using the mono/stereo output when in the blend position. Any advice on correcting this problem?

If your Peavey 14 BT mixer is not allowing you to pan the audio signal and is sending the same signal to both outputs, there could be a few potential reasons for this issue. Here are some troubleshooting steps you can take to address the problem:
1. **Check the Pan Controls:** Make sure you're using the correct pan controls for the channels you're trying to pan. The pan controls are typically knobs labeled "Pan" or "Balance" on each channel strip. Ensure that they're set to the desired positions.
2. **Reset Pan Controls:** If you've already adjusted the pan controls and they're not working as expected, try resetting them to their center positions. This can help eliminate any accidental settings that might be causing the issue.
3. **Channel Routing:** Some mixers have routing options that can affect panning. Check if there are any routing switches or buttons that might be affecting the signal routing for each channel.
4. **Mono/Stereo Mode:** Some mixers have a mono/stereo mode switch that can affect panning. Make sure the mixer is in the appropriate mode for your setup.
5. **Master Pan Control:** Ensure that the master stereo output pan control is set to the center position. If it's panned to one side, it can affect the overall stereo output.
6. **Test Different Channels:** Try panning different channels to see if the issue is specific to one channel or affecting multiple channels.
7. **Firmware/Software Update:** If your mixer has digital components or software control, check if there are any firmware updates available. Sometimes, software updates can address functionality issues.
8. **Physical Damage or Wear:** Inspect the pan controls and associated circuitry for any physical damage or wear that could be causing the issue.
9. **Factory Reset:** If none of the above steps resolve the issue, you might consider performing a factory reset on the mixer. Be sure to back up any important settings before doing this.
10. **Professional Service:** If the problem persists after trying these steps, it might be a more complex internal issue that requires professional servicing. Contact Peavey's customer support or a qualified audio technician for further assistance.
Remember that the exact steps and controls can vary depending on the model of your Peavey mixer. Refer to the user manual for your specific model for more detailed information on troubleshooting and operation.

On the rear of the piano there will be two 1/4" jacks labeled Output Left and Right. One will be labled Mono as well. If you are using a stereo amp, use both, and if a mono amp use just the mono output. If your amp is a guitar type, connect a shielded cable with 1/4" phone jacks such as you'd use with an electric guitar from these jacks to your amplifier. If you are useing a home stereo amp, you will need a cable with 1/4" phone jacks from the piano to RCA phono jacks on the amp end.

This depends on what you are trying to do. If you want a mono output from the amp switch it to mono mode and go into one input on the amp, this will mean the amp only works mono.

If your source is stereo you will need to use two inputs on the mixer and pan them both to the side you will be sending to the amp. This will cost you two mono inputs on the mixer though.

If you have anything stereo this is the route you will need to take but I don't see why you would want to do this as surely you'd be better running everything stereo (two channel) and panning any mono signals where you want them and leaving stereo as stereo.

use the xlr (3 prong) main left and right outputs of the board. get xlr to 1/4 inch cables. one end will be 3 prong, to plug into the mixer, then the other end will be a mono 1/4 inch plug, like a big headphone plug. Then you have to get a dual mono 1/4 inch to stereo 1/8 inch adapter and plug it noto the line in. if there is no lone in, but a microphone jack instead, you will get a mono signal instead of a stereo signal. in this case, just use 1 channel of the mixer, instead of both of the stereo outs, and use a single mono 1/4 inch to mono 1/8 inch adapter.

the xlr to 1/4 inch cables can be purchased at a music store. the 1/4 inch to 1/8 inch adapters will probably need to be purchased at radio shack.

Hi,

Seems that you hooked it up in the 3-way mono setting.

Realize that when you plug into the one jack it disconnects the fingerboard pickup from the mix.

DO NOT USE "stereo" cables as it is intended to use TWO MONO cables, one for each side of the stereo.

IF you plug into the one jack that will connect to the bridge pickup, it will disconnect the fingerboard pickup from the mix BUT leave the fingerboard on its own jack.
That same jack will have BOTH fingerboard and bridge pickups IF the second jack (bridge) is not plugged into.

This is according to the schematic. If you find that yours works backwards, then either the schematic is wrong OR your guitar pickups may be electrically swapped.

Assuming that you have a single point speaker system, (or piggyback speakers) use the mono output, otherwise, the tone modifications that you apply to one of the channels, wont be heard. The two channels have independent setups.

Go to www.korgpa.com/pa_root/pdf/pa800/Pa800-200UM-ENG.pdf.Page 226 has the audio output section.Page 19 has the rear panel explanation. Left/Right: These are the main stereo outputs. Use them to send the final stereo mix to an external device. Connect either to get a mono output. Set the output level with the Master Volume slider. 1/1: These are the sub outputs. Use these to create a stereo submix of just some tracks or to output just a single instrument to be mixed alone or to be processed or amplified externally. Not: the Master Volume slider has no effect on these outputs. Signal is sent dry with no effects applied. Hope this helps.

Both stereo and mono jacks will work fine on the inputs, any guitar or mic lead will work a treat.

You can use stereo jacks for the outputs too, but to keep it simple just use a mono jack in the L out and a mono jack in the R out.
