Line 6 Relay Digital Guitar Wireless System
System Overview
- Wireless freedom in any size venue, home, or office
- Easy to use—no setup required
- Automatically chooses the best channel for true playing freedom
- Up to 7 hours of playing time per charge
- Optional manual channel selection for setups with multiple wireless units (Relay G10S and select Relay Ready products)
- Best in class sound quality provided by:
- 24-bit uncompressed digital transmission
- Best in class DAC and ADC provide super low noise transmission (better than 110dB dynamic range)
- Up to 50 feet (15 meters) for Relay G10, or up to 130 feet (40 meters) for Relay G10S, line-of-sight range
2.4GHz Wireless
Since the Line 6 Relay is a 2.4GHz wireless system, please avoid placing the receiver next to other RF transmitting equipment. We recommend that you install the G10 or G10S receiver at least 10 feet (3 meters) away from RF transmitters (e.g., WiFi routers).
The Relay system automatically selects the best channel when the transmitter is docked (for the G10S receiver, its Channel Selector needs to be set to AUTO).
After changing WiFi or other 2.4GHz wireless channels, please dock the transmitter in the receiver for at least 10 seconds.

Getting Started
Using the Relay G10TII Transmitter with a Relay G10 or G10S Receiver
- Insert the Relay G10TII transmitter all the way into the receiver dock to allow the battery to charge. A green steady LED on the transmitter indicates the transmitter is fully charged. A full charge takes approximately 3 hours.
- While the G10TII is docked in the receiver, the system scans the environment and automatically selects the optimal wireless channel.
The G10S receiver’s channel selector must be set to AUTO for this step
- Insert the G10TII transmitter into your instrument.
- Connect the receiver to a power source using the power adapter provided with your device. Connect the Relay G10 or G10S receiver’s 1/4″ Instrument Output into an amp or FX unit.
- For use as a DI with bass and acoustic guitars, connect the Relay G10 or G10S receiver’s XLR DI Out to a mixer or audio interface.
Using a Relay G10TII Transmitter with Relay-Ready Devices
In addition to being compatible with Line 6 wireless receivers, the Relay G10TII transmitter also works with a number of select Relay-Ready devices. Please see https://line6.com/g10info/ for more info.
To use G10TII with your Relay-Ready device, please see the following steps.
- Power your Relay-Ready device on and insert the Relay G10TII into the input jack.
The Relay-Ready device charges the G10TII transmitter, as well as scans the environment, and automatically selects the optimal wireless channel and frequency. - Once fully charged, insert the G10TII transmitter into your instrument. Please refer to the documentation of your Relay-Ready product for additional details.
Relay G10TII Transmitter Details
- Battery Status – This LED illuminates green when the transmitter is powered on and while more than 30 minutes of operating time remains. The LED flashes red when less than 30 minutes of operating time remain—also Check for additional LED states.
When the transmitter is plugged into the receiver for charging, a flashing red LED indicates less than30minutes of battery operation, a flashing green LED indicates more than 30 minutes of battery operation, and a steady green LED indicates a fully charged transmitter. A full charge takes approximately 3 hours. - 1/4″ Plug – Plugs into instrument.
- Antenna – The calibrated internal antenna avoids damage or deformity in normal use. Avoid covering the antenna area with metallic fabrics or accessories, and avoid direct contact with parts of the performer’s body for best results.
Sleep Mode – To extend battery life, sleep mode is activated after a period of 4 minutes where no audio input is detected. The transmitter “wakes up” automatically when the instrument is played.
Important Information About the G10TII Transmitter
- The recommended charging temperature range of the G10TII transmitter is specified as 50° F to 86° F (10° C to 30° C).
- The recommended operating temperature range of the G10TII transmitter is specified as 32° F to 122° F (0° C to 50° C).
- Line 6 recommends charging the G10TII transmitter at least every 6 months, based on best practices for lithium-ion batteries.
| G10TII Transmitter (docked in receiver)* | |
| LED State | Condition |
| Red (slow flash) | Charging, less than 30 minutes battery time remaining† |
| Green (slow flash) | Charging, more than 30 minutes battery time remaining |
| Green (solid) | Fully charged‡ |
| Dim Red/Pink, may turn off | G10TII is not docked properly—Try un-docking and re-docking |
| Red (three quick flashes) | G10TII charging has stopped due to being outside the supported temperature range—Charging will resume after 5 minutes at 50° F to 86° F (10° C to 30° C)§ |
| Orange (solid) | Docked and connected to Mac or PC, firmware update in progress |
| Off | Receiver not powered (transmitter enters sleep mode after 4 minutes if receiver power is disconnected) |
| G10TII Transmitter (connected to instrument) | |
| LED State | Condition |
| Green (solid) | Transmitting, more than 30 minutes battery time remaining |
| Red (slow flash) | Transmitting, less than 30 minutes battery time remaining |
| Off | Connected to an instrument but not enough remaining battery power to transmit‖ or removed from instrument |
* When the G10TII is docked in a receiver or Relay-Ready device, the G10TII LED initially indicates amber, red, or green, depending on its current battery state. This is followed by four flashes (red) as the device initializes. Once this completes, the G10TII LED proceeds to indicate its remaining battery time.
† All values stated for amount of battery time remaining are approximate, and the exact amount of battery time remaining when an LED state is indicated may vary slightly between charges. When the G10TII flashes red, it may have up to 60 minutes of battery time remaining.
‡ If the G10TII reaches a full charge (solid green) and remains docked, the G10TII LED may eventually flash green again. This is expected behavior as the G10TII may discharge slightly after reaching a full charge, and its LED may then flash green until it again reaches a full charge.
§ If the lockout indication continues for over 10 minutes, please stop charging and try again in a cooler environment condition.
‖ When the G10TII has insufficient power to transmit, its LED may indicate a pattern of five quick red flashes when connected to an instrument and audio is detected. This is the expected behavior.
Relay G10 Receiver Details
- Micro USB – Use for primary DC (5V DC /1A) power and firmware updates.
- Output A – ¼” unbalanced, full performance output intended to drive a guitar/bass amplifier, stomp box, or multi-effects input.
- Output B – XLR balanced, full performance output intended to connect to a mixing console, PA system, audio interface, or similar.
