pinoy1 Posted May 31, 2014 Share Posted May 31, 2014 Hello folks, When I plugged my JTV-69s guitar into my POD HD Pro using the 1/4 cable, the volume level drop-offs to about 20% compare to when I'm using the VDI cable. Does anybody else experiencing a volume drop-off when using the 1/4 input on your POD HD devices instead of using the VDI cable input? Thanks.

Charlie_Watt Posted May 31, 2014 Share Posted May 31, 2014 They are two totally different signal paths. Not surprising that they are not matched. With the 1/4 inch, the D/A is in the JTV. WIth the VDI, it's in the Pod. 1 Quote Link to comment Share on other sites More sharing options...

It's not that big of a deal but sometimes I use the 1/4 cable when I need to have more distance from my POD HD Pro. I don't have a longer VDI cable, yet.

Just stick to one signal unless you honestly have to use 1/4. Quote Link to comment Share on other sites More sharing options...

clay-man Posted May 31, 2014 Share Posted May 31, 2014 The only thing I can suggest is a pedal that can boost levels or just adjust your amp accordingly. Quote Link to comment Share on other sites More sharing options...

WIth the VDI, it's in the Pod. Gharlie, with 1/4" AD takes place @POD (Check the diagram @13:03 on the supplied link) With VDI AD takes place @the piezos. Both cases DA is done @POD's output.

clay-man Posted June 1, 2014 Share Posted June 1, 2014 A/D is done when the piezo signal goes into the DSP. D/A happens before the 1/4 output. In a VDI it happens before the POD's output. 1 Quote Link to comment Share on other sites More sharing options...
jandrio Posted June 2, 2014 Share Posted June 2, 2014 (edited) A/D is done when the piezo signal goes into the DSP. D/A happens before the 1/4 output. In a VDI it happens before the POD's output. assuming the Variax mode is deactivated via the "Guitar Model Selector" and the JTV is in mags mode, since mags can be used WITHOUT battery, there is NO AD conversion at all, the signal goes out thru the JTV 1/4" analogue, it continues thru the POD's 1/4" guitar input analogue and it is AD converted INSIDE the POD. if the JTV is in variax mode, AD is done as per clay-man's post. then if going out thru the JTV 1/4" jack, there is nother DA. if it goes VDI there is no extra conversion, it goes digital.
