Hi Raghu,

Make sure you are using regular Instrument cables (TS) Tip-Sleeve Type cables. The outputs on the synth are "unbalanced".
Make sure you are going into two separate channels on the receiving device with one channel panned hard Left and the other panned hard Right. In a case where the mixer has a Stereo Input it maybe pre-panned.

What type of device are you connected to and by what type of cables? Those are the first places to start.
Once we've verified those we can proceed to next step.

If you can connect the outputs (please connect cables to both outputs) to a mixer with some kind of metering that will be helpful. Let us know what you have available.

Hi Thanks for the quick reply.

I am using TS type cables and connecting to stranger PM102.

Not connecting the cables through a mixer and it is directly given to 2 different strangers.

While connecting separately output is audible and clear.

However when connected together L output is not audible., I have tried swapping the speakers ,cables separately as well.

Also there is no panning feature available in my speakers.

Not sure what is causing the trouble.

When connecting cables to the MOXF you must connect two cables. One to the LEFT, the other to the RIGHT Output.

If you are going to connect just one cable, then only connect to the LEFT Output - this is why it is labeled "L/Mono". When only one cable is used it should be connected to this Output to preserve phasing when playing in a mono system.

Never, ever Connect just one cable to the RIGHT Output - this is wrong! Incorrect!
You cannot test the signal strength this way. I hope you understand. I'll say again: NEVER connect only one cable to just the RIGHT side. This is ALWAYS wrong.

To test output balance requires two cables (both connected at all times), you need two Stranger PM102, Connect LEFT Output to one amplifier, the RIGHT Output to the other amplifier. Set both amplifiers to same level. Place the amplifiers several feet apart. Play the MOXF.

Call up KEYBOARD Voice: "Vintage'74" - this is a FenderRhodes sound that will pan Left-to-Right using the "Auto-Pan" effect. The sound should be balanced in level, Left versus Right.

If you are using just one Stranger PM102, then you should use just one TS cable, connect the "L/Mono" Output to one Input on the amplifier. That's it.

What happens when you use balanced TRS cable with unbalanced instrument output? I've been using balanced cable from DX7 to console for years and never had a problem..

Hello!

I have a similar problem with my MOXF 6, I am connecting the the left channel to a studio monitor and the right channel to another studio monitor.

After sometime, Right channel stops working, or makes distortion at very low volume.

After that, i checked also the headphones, and also in the headphones the problem persist.

I am turning off and on again the keyboard and everything works fine....for a while...then the problem appears.

Did you solved it? did you had same problem on the headphones also?

Honestly..i don t know what to do, is really strange that the right channel stop working suddendly without any reason. And then is back again..

Hi, I'm having exactly the same problem here. Any solutions?
Thanks

If you determine that is the case, you should contact an authorized service location.

Hello.
I have similar issue.
I use to split my moxf6 keyboard in order to use 2 different sounds together, one with the left hand, the other with the right hand.
I also pan the left side all to L and the right side all to R, so I can manage the 2 different sounds separately on the mixer,
L jack - channel 1 on the mixer,
R jack - channel 2.
Like this I can equalise, regulate volumes separately from the mixer.
The two sounds volumes are also set on the keyboard (and so saved) in a way that if I use the keyboard just with L/mono output, they are balanced (more or less on any speaker I go to use).

Last night something very strange happened.
I was playing in L/mono and suddenly the right side of the keyboard got to an extremely low volume.
I tried to change sound (A1 to A2, A3, B4 and so on) and the problem was the same with all the R panned sounds.

I tried to enter MoxF setting and panned the right sound back to "C" (or further to extreme L) and like that the volume got back to normal!

It's like suddenly the R panned volume of all sounds got set to a minimum level, barely audible!
The same happen if I go to a new sound and try to pan it to the R.

Afterwards I decided to try using both keyboard output channels L and R (so not mono anymore) and the problem was still persisting.
Like this I also noticed that reducing both R side gain and volume levels to minimum, the volume doesn't go to zero/mute as it is supposed to, but it stays to that extremely low level...!

Please help me, I really have no idea of what happened and how to fix it!

Stereo does not work as you are using the instrument. If you have a home high fidelity system placing the radio in the left channel and the CD player in the right is not stereo... not the intended use of “Stereo” — so as long you understand this.... you posted in this thread that explains what L/Mono means and how it should be used... so we will assume you have both channels connected at all times!

((You don’t mention your cables... please do not compound your issue by using anything but standard 1/4” unbalanced TS signal cables... using a balanced cable can cause issues in your unconventional usage))

Many of the Effects processors on the MOXF are true stereo effects; two inputs/two outputs, some have mono input and stereo output.
Do you have any idea which effects are in play? Yes, it matters.

Just because you pan something fully Left, does not mean that no signal arrives in the Right channel... it can get there due to the System Effects. It is your responsibility to work this out. If you call up a stereo instrument like the Full Concert Grand, and Pan it to one side, you narrow the stereo field of this Voice to the point of killing its stereo-ness, if this sound has Rev Send set, then some of the Reverb Return will arrive in the right channel. And vice versa for sounds panned right, they may arrive in the left channel via the Reverb Return. A ghostly and low level signal is what it will sound like... While testing BYPASS the REV and CHO processors.

Since I’ve never setup to use the system as you describe, I cannot report on whether or not you can actually damage the instrument by overloading one side (I don’t believe you can without it being obvious that you are severely overloading it). I will suggest that when troubleshooting the instrument, please return to a more conventional use.

Connect the unit normally (unbalanced cables or better headphones) using Factory Presets, using both channels in true stereo.
Also check the results using a pair of headphones (this will eliminate physical damage to the Output jack)

Let us know.

Extra Credit: How to do Separate Outputs properly...
The proper way to accomplish what you are attempting... would be to assign one set of sounds to the MAIN L/R Output, and the other set of sounds to the ASGN L/R Outputs, this would give discreet (and proper) control over each set of outputs. This would mean upgrading to a top-of-the-line product... Motif XF (discontinued) or MONTAGE (current).

The way it works in these products is... you can on a Part by Part basis, assign the Part to the Part Outputs as desired. This allows you to program all of your guitar leads to a guitar amp, or all of your bass sounds to a bass amp. Many use the Asgn L/R to feed their B3 organ parts to a Leslie Simulator, etc., etc. and since the “Part Output” parameter allows this condition to be stored, it is possible to prepare the assignments ahead of time — this way whenever you recall your organ sound it is automatically pre-routed to the Assignable L/R Outputs...

There is one MOXF Output — it can be used as a Stereo or a Mono Output
There is one MOXF Input — it can accommodate a Stereo or a Mono Input.

Seems like this is happening to multiple people ( https://www.yamahasynth.com/ask-a-question/left-output-dead-when-right-is-used-left-phones-is-faint-and-distorted-always )

I just noticed the same issue (I have a MOX8, but should be similar enough to the MOXF), and a temporary fix in my case is lowering the master volume by a few millimeters, if I push it back to 100% I get the same problem again, only right channel working.

So something is clearly dying, either the volume slider potentiometer or a capacitor on its last leg.

My setup is simple, TS cable each going directly to separate powered speakers

If you are having an issue with your instruments, please take it to an authorized service center... if there is an issue they will be able to fix it for you.
