White Noise In Effect Loop

[lef38]

Hi,

 

I've got noticeable white noise in the effects loop, even if i simply plug one (good quality) patch cable from send to return.

Any tip on how to reduce it ?

is it there with al volume and gain at zero?

Have you tried adjusting the Send and Return levels?

[lef38]

Send and return are left to defaults: 0 db

With these settings the volume is kept at the same level whether the effects loop is on or off.

I have ecountered this problem recently.  I found that if I play the FX loop before the AMP I get the hissing sound, even if I patch the fx loop.  If I move the fx loop after the mixer, I get no noise.  The interesting thing is that if I put noise gate after the fx loop I get no noise.

 

I have even set the amps to zero.

 

Any thoughts.

Would someone try this on their HD500?

Place the fx loop before the amp run a cable send to return and see if you hear anythin.

Check the level switch.  If it is set to 'Line' then moved it over to 'stomp'.

 

The line setting can be very noisy (hissy) and not appropriate for most effects anyhow. If you do not hear a difference when you change the setting try wiggling the switch and see if it crackles.  Mine was quite dirty and I needed to spray it with contact cleaner before it would switch properly.    

 

If you effects give you a setup choice between Line level (+4dB) or stomp/amp/consumer level (-10dB) then use the stomp level.

Thanks for the reply.  It is already set for stomp.  The noise is heard even if you run a cable from the send to the return, nothing else in line.

I get white noise too and I need to put the FX Loop block before the mixer because I'm using the Send to go to an input of the M20D.  I don't know what to do...
