Right channel cuts out when I increase the volume

i suggest you contact Behringer Customer Service for advixce. Without the setup in front of me, it's hard to figure out the wire routeing, switch positions, ect. that may be leading to this problem. As they would be the people most familiar with the gear, they'sd be the people to ask. http://www.music-group.com/support/behringer/askquestion

Hi, use the RCA/Phono connections for the Tape In & Out. The level will be set by the Master/Main fader. If that is not so convenient (& assuming it's a PMP4000?) there should be a "Main 2" output & connections with the level controlled separately to Main 1 via a Knob / Rotary control over to the right above the "Mono" fader... Hope that helps... Good Luck!

1. Check the Headphone Output:
   • Make sure that the headphone output jack is clean and free of any debris. Sometimes, dirt or dust can accumulate and affect the signal.
2. Output Mode:
   • Double-check the output mode settings on your Boss BR 1180. There might be a setting that affects the stereo output, so ensure that it is set correctly.
3. Output Routing:
   • Verify that the output routing settings are correct. Check if there's a setting that might be causing the output to be directed to only one side.
4. Master Output:
   • Check the master output settings to ensure they are balanced. If there's an imbalance in the master output settings, it could affect the stereo playback.
5. Factory Reset:
   • Consider performing a factory reset on your Boss BR 1180. This can often resolve software-related issues that might be causing the playback problem.
6. External Monitor:
   • If possible, connect the recorder to an external speaker or monitor system using the appropriate outputs to see if the issue persists.
7. Contact Support:
   • If none of the above steps resolves the issue, it might be a hardware problem within the unit. You might need to contact Boss support or a professional technician for further assistance or repairs.

Maybe try adjusting the MASTER level?

Good Luck

Other settings
Adjusting the master level You can adjust the level of the headphone and the stereo out by turning the MAIN VOLUME knob. The MAIN
VOLUME changes the analog signal level. This will also adjust the entire level of the MPC1000 digitally.
01. Press the [MODE] key and then the [PAD 10] (OTHER).
It switches to the OTHER mode.
02. Press the [F1] (GLOBAL) key.
The GLOBAL page will be displayed.
03. In the Master level field, set the level.
You will set the digital signal level, which will be sent out to the DA converter. The MPC1000 can output up to
32 sounds simultaneously. There is the great difference in the level when you play single sample and play 32
sounds. If you increase the value in the Mater level field, you can increase the entire level of the MPC1000 to
create more powerful sound with less noise. However, if you playback many sounds at the same time, the
level may be overloaded, which may cause distortion. If you decrease the value in the Master level field, you
can prevent distortion when you play many sounds at the same time. However, you cannot have a good
result in respect to the noise or punch of the sound. Set the appropriate value in the Master level field
depending on the application.

left channel control pot dirty most likely. is there a slider type pot on channel? this would have to be cleaned with dustoff spray.

Try plugging in a set of headphones into each of the mon left and right. If the monitor sliders are up AND the channel monitor knobs are up you should be able to hear in ONE SIDE only of the headphones. If not, then you may have failed to power your monitor amp or speakers from the SAME receptacle as the mixer and this can result in ground bouncein building wiring that will blow out the driver chips for the mon signals.

This is a little too in depth as I do not know this equipment well. It does sound terminal though

try hooking headphones to the output and see if the crackling is still there.

then, try it with the speakers, at a lower computer voume level and higher speaker volume level. perhaps the headphone output is too loud and distorting in the speaker inputs.

Contrary to what's posted above, the Marshall MG series does not pass the speaker power output through the headphone jack, and inserting the headphones into the jack does not disable the speaker. The headphone amp is a separate circuit and it's input is taken before the master volume. So Jan's post is exactly right. Turn off the master volume and turn up all the other gain/volumes as high as they will go. The other issue is that the headphone jack's output does not drive low efficiency headphones well, so you need some headphones similar to Sony's MDR-V700s to hear it well. Earbuds just don't cut it.

I had that problem too. What you need to check is the input level on the right side. Turn the wheel all the way up to 100 and the internal mic should be fine.
