Q: Can I use multiple transmitters with 1 receiver?
A: Yes, you can use multiple transmitters with 1 receiver, however not at the same time on the same channel. The best practice for that type of usage is to have Transmitter A on channel 1 and Transmitter B on channel 2. Then switching the channel on your receiver from channel 1 to channel 2 will toggle which transmitter you will be hearing. You can do this with as many receivers as you have channels, provided each transmitter is on a different channel and you change the channel on your receiver accordingly. You can also set multiple transmitters to one channel, and turn them all off except for the one you'd be using. This way, when you switch instruments, you'd turn off transmitter A on the first instrument, then pick up the next instrument and turn on transmitter B. Just be sure that no one else using a Line 6 wireless system is using the same channel.
Q: Are all Line 6 wireless transmitters and receivers interchangable?
A: Yes, any Line 6 brand wireless transmitter or microphone will work with any Line 6 receiver. It does not matter if they are XD-V or Relay systems, you can mix and match receivers with transmitters and they will work as long as the transmitter and receiver correspond to the same channel.
Q: Is the Relay G5/G90 transmitter compatible with the X2 receiver (or vice versa)?
A: Both systems run in completely different frequency ranges, so they are not interchangeable. However, the X2 and Relay units can be used on the same stage (along with any other analog wireless systems) with no problems.
Q: Where do I get a Relay G50/G90 Series Wireless System?
A: The Relay G50/G90 wireless units are available at all authorized Line 6 dealers. To locate a dealer near you, please see the Line 6 Dealer Finder:

Q: Where can I purchase replacement Relay G50 transmitters (TBP12) or receivers (RXS12)?
A: Individual transmitters and receivers can be ordered from any Line 6 dealer.
Q: What are the specs on the provided Relay G50 Series power supply?
A: 9V DC, 500mA, center pin negative (2.1mm). See the following link for more power supply FAQs:
Power Supply and Amp Power F.A.Q.
Q: How is the Relay G90 receiver powered?
A: The Relay G90 uses a standard IEC power cable.
Q: Can I use a Voodoo Lab Pedal Power Plus 2 to power the Relay G50 receiver?
A: Yes, but you will need to use the Voodoo lab "current doubler" cable and you will need to use outputs 5 & 6 of the Pedal Power Plus in "normal" position. VooDoo model PPAP.
Q: What type of cable do I need between my guitar & Relay TBP12 transmitter?
A: The Relay G50/G90 Transmitter (TBP12) uses a TA4f to ¼” cable.
Q: What is the pinout for wiring to a TA4F connector?
A: Pin 1 - Gnd
Pin 2 - V+
Pin 3 - Signal
Pin 4 - Z (leave open for instrument)(short to pin 3 for mic)
Q: How many channels does the G50/G90 have? Do they share channels with the G30 system?
A: The G50/G90 have 12 channels, which share the first 6 channels with the G30.
Q: Can I use the TBP12 from a G50 to transmit to a G90 or G30 (or vice versa?)
A: Yes. All 2.4gHz Line 6 transmitters work with all Line 6 2.4gHz receivers to the lowest limitation, channel count, features, etc.
Q: What type of antennas work with the G50 and G90?
G50: ¼ wave antennas, BNC-type connectors; detachable.
G90: ½ wave antennas. The antennas can be detached but RG58-50 ohm radio wire connection is required. Be sure the antennas are not inside a metal case or touching any metal and get your antennas as high as possible.
Q: How long does the pair of AA batteries in the transmitter typically last?
A: 8 hours on high power & 11 hours on low power. If you leave the transmitter cable plugged but turn the power off on the transmitter, there is no battery draw.
Q: How does the battery meter work?
A: The battery meter displays 20 minute increments. Be aware of "alkaline rebound" when turning off the unit and turning it back on, as it may look like it has more power than it really has.
Q: Can I use rechargeable batteries?
A: Yes, but the hours and minutes are calibrated to alkaline batteries so the power reading may be inaccurate. Some rechargables while labeled AA are not true AA size and will not work.
Q: What is the difference between the main output and the tuner output?
A: The only difference is the tuner output still works when the transmitter is muted.
Q: What is different about the Relay G50/G90 system compared to the X2 series?
A: The Relay system works on a higher frequency (2.4 Ghz) and operates on 12 channels rather than 5.
Q: Can the RXR12 Receiver antennas be linked together?
A: Up to 6 receivers can be daisy-chained together. The last unit in the chain should be "terminated" when linking receivers together.
Q: I'm a harmonica player and would like to use the G30 with a bullet microphone (high impedance and high output). Its output peaks at approximately 3V to 4V. Will there be clipping or distortion of the output?
A: No problem with either impedance or input level. The Relay transmitters (TBP06 and TBP12) will handle 6V inputs.
Q: How do I register my Relay G50/G90 System?
Line 6 Product Registration F.A.Q.
Q: What do the different colors states mean on the TBP12 transmitter?
TBP12 LED States:
Blue LED = full
Solid red LED = Low
Flashing red LED = Very Low / Change batteries
