Should your system not function initially, it could be that your transmitter has been set to a different RF mode. Please see the instructions below on switching RF modes on the TBP12 Transmitter:

  • Turn the TBP12 transmitter on.
  • Hold the SELECT button until the channel number flashes.
  • While holding down the SELECT button, press and release the VALUE button, then release the SELECT button.
  • The display will briefly show RF1 or RF2 to indicate what mode it’s set to. This setting is retained when powering off and is displayed each time power is turned on.

Just curious but I thought the new receivers were supposed to work with either rf mode, why do they only work with rf1?

Newer receivers with firmware versions of 2.X will automatically switch modes to match the first transmitter they "see".  Earlier units operate in RF1 mode only (until the firmware is upgraded.)

 

RF2 mode operation does require that you scan for clear channels to operate on.  This is not a requirement in RF1 mode operation.  Each mode has advantages, but RF1 mode requires very little setup and so it is easier and more robust in more situations.

Ok so it sounds like I would want to use rf1 anyway.  If I have a brand new unit why wouldn't it be upgraded already?

Depends on the model and the date of manufacturer

OK ... I will admit, I was a tad bit frusterated when I upgraded my XDS-Plus to the G50, only to have the receiver see the transmitter ... it took me 2 shows before I finally found this and "voila" worked like a charm.  

I bought one, took it back thinking it was a bum unit ... only for the 2nd one (that was ordered in) to do the exact same thing ... 

 

To clarify what is being said up there ^^^^^, 

 

 

a) the new Line 6 transmitters are shipped with the setting to RF2 by default , so if your reciever is not seeing your transmitter (you have 3 red lights instead of all green ones on the reciever) 

 

you must then

  • Turn the TBP12 transmitter on.
  • Hold the SELECT button until the channel number flashes.
  • While holding down the SELECT button, press and release the VALUE button, then release the SELECT button.
  • The display will briefly show RF1 or RF2 to indicate what mode it’s set to. This setting is retained when powering off and is displayed each time power is turned on.  If it says RF2, change it to RF1.

you should be ready to play at that point ... it worked for me!

This discussion may be helpful to those considering the relative merits of Line 6's two RF frequency schemes:

Wow thanks for starting this topic, I had the same issue thinking I blew it up with using incorrect power adaptor or something.

I followed all the instructions in the manual yet there is no mention in the manuals or pilot guide about changing RF1 or RF2.

(even the trouble shooting section didnt mention it)

 

So thank you thank you thank you.

 

And Thanks to Ron for the tip on converting the U.S. adaptor , works a treat

I purchased a Relay G50 Digital Wireless Guitar System and upon receiving it, I opened it up, connected the receiver to my amp and the transmitter to my instrument and everything worked great. I was happy until today when I tried to use it for practice. I turned it on just like last time and I got no sound. I have tried the steps to switch the RF modes and have switched them multiple times with no success. I'm curious about this said "scanning" process. I see comments that you have to scan for clear channels, but nothing on what that process is in practice. I'm assuming you are saying you have to change the channel on the receiver then change the channel on the transmitter one at a time until you are successful in transmitting and receiving a signal. If that's the case, I have tried that and have had no success.

 

I am powering my RSX12 receiver with a Voodoo Labs Pedal Power 2 plus. My transmitter says I'm running firmware 2.00. The power light is illuminated on my receiver and after a short time, (a second or two) no other lights, (audio is red; transmitter signal is red; transmitter battery is green) are staying on. My transmitter has a blue light on for the power and when I play the instrument the green light is illuminated for the audio.

 

I'm not sure what happened, but I have spent a few hours here trying to figure it out by going through the owner manual, knowledge base and forums. This has been rather frustrating experience and I am looking for an answer to figure out my problem before I return this and go back to using cables.

Hi williambodily,

 

There is no "scanning" process. You have to search for a channel manually as you described.

 

It is possible that your receiver still bears the old firmware, in which case it will not work with RF2 mode. That's alright because RF1 mode is recommended in almost all cases. So make sure your transmitter is set to RF1 mode by following the instructions outlined above in this forum topic.

 

Just a thought, since you say you are powering the receiver with a Voodoo Labs Pedal Power 2+. When using that unit you must use the "current doubling" cable on the 5 and 6 outs.  Check that you have the proper cable as the "voltage doubling" cable looks identical but is not the right one. You may not be providing enough power to your receiver. Did you check to see if it functions properly with the regular DC1g power supply it came with?

 

Hope this helps.
