Names and Functions

Control Panel

THR30II Wireless / THR10II Wireless / THR10II

• 1 [ ] (Power Button) / Power Button LED: This is the unit's power button. When the power is ON, the Power Button LED, the lamp corresponding to the selected amp type, and the Power Lamp in the speaker cabinet light up.
• 2 LED Display: Indicates each of the THR-II's settings and conditions.
• 3 [TAP/TUNER] button:
  • Tuner Function: Holding the switch for 1 second engages the tuner function and lights the pitch indicators. The tuner is calibrated to A4=440Hz. Tune the guitar until the desired pitch appears in the LED display. When only the circle [O] in the center of the display is visible, tuning is accurate.
  • Pitch indicators: Low pitch [<], In tune [O], High pitch [>].
  • Press the [TAP/TUNER] button (less than one second) to turn OFF the tuner function.
  • Note: When the tuner function is set to ON, the guitar sound to the main speaker, [PHONES] jack, and [USB] jack is muted. The sounds from the [AUX] jack, [USB] jack, and Bluetooth are output to the main speaker and [PHONES] jack.
• [AMP] knob: Selects the amp type. The lamp for the corresponding amp type lights. When the power is turned ON, the most recent amp type is selected.
• [AMP] switch (THR30II Wireless only): Selects the amp mode. Selects the amp modeling by combination of amp mode and amp type. The [AMP] knob lamp lights for the corresponding amp mode color. Refer to the Amp Modeling List (page 20) for details.
• [GAIN] knob: Adjusts the amount of preamp gain. Turn clockwise to increase gain. When ACO is selected, the sound is a mix of front-mic'd and pickup sound of an acoustic electric guitar.
• [MASTER] knob: Adjusts the volume for the guitar sound. Turn clockwise to increase volume and create power amp distortion. When BASS, ACO, or FLAT is selected, this only adjusts the volume.
• [BASS] knob: Tone adjustment for the guitar's sound. Turn clockwise to enhance low-range frequencies.
• [MIDDLE] knob: Tone adjustment for the guitar's sound. Turn clockwise to enhance mid-range frequencies.
• [TREBLE] knob: Tone adjustment for the guitar's sound. Turn clockwise to enhance high-range frequencies.
• [EFFECT] knob: Selects one of four effects: CHORUS, FLANGER, PHASER, or TREMOLO. Turn clockwise to increase the amount of each effect. Turn fully counterclockwise to set the effect OFF.
• [ECHO/REV] knob: Selects one of four effects: ECHO, ECHO/REV, SPRING, or HALL. Turn clockwise to increase the amount of each effect. Turn fully counterclockwise to set the effect OFF. When ECHO or ECHO/REV is selected, the [TAP/TUNER] button can be used to set the delay time.
• [GUITAR] knob: Adjusts the overall volume of the guitar sound. This knob's setting has no effect on the signal sent to the [USB] jack. The volume output to the [LINE OUT] jacks is constant regardless of this knob's setting.
• [AUDIO] knob: Adjusts the audio playback volume for audio from a computer via USB, an external audio device via AUX, or a smart device via Bluetooth.
• [INPUT] jack: Standard phone jack for connecting a guitar. Connecting a Wireless Transmitter starts charging it automatically and sets the optimal channel after 10 seconds (THR-II Wireless only).
• [PHONES] jack: Stereo mini phone jack for connecting stereo headphones. Speaker sound is muted when a plug is inserted.
• [AUX] jack: Stereo mini phone jack for connecting an external audio device. Signal received at the [AUX] jack is not sent to the [USB] jack.
• [USER MEMORY] [1] [2] [3] [4] [5] button: Saves up to five sets of amp section controller settings. Press and hold a button for about 2 seconds to save.

Connection Example (on THR30II Wireless)

Diagram Description: Illustrates connecting a computer, tablets, and smartphones via USB cable to the THR-II. Shows power connection via adapter. Depicts external audio devices connected via AUX. Shows Bluetooth connection for music playback and tone editing. Also shows wireless guitar connection.

• Order for turning the power on: THR30II Wireless → Mixer → Amp (or powered speaker)
• Order for turning the power off: Amp (or powered speaker) → Mixer → THR30II Wireless

Precautions for using the USB jack

Use an AB type USB cable of less than 3 meters; USB 3.0 cables cannot be used. Wake the computer from suspended/sleep/standby mode before connecting. Quit all running applications and set computer volume to minimum before connecting/disconnecting USB. Set THR-II OUTPUT controls ([GUITAR] and [AUDIO] knobs) to minimum when connecting/disconnecting USB. Wait at least 6 seconds between connecting or disconnecting the USB cable.

Power

The THR-II Wireless can operate on DC power (via power adaptor) or with its built-in rechargeable battery. The THR10II operates on DC power only.

Note: When using the THR-II Wireless with the built-in rechargeable battery, the maximum output volume is reduced.

When using the power adaptor

Connect the supplied power cord to the power adapter, then connect the adapter to the [15V] DC IN jack on the rear panel. Connect the AC plug to a power outlet.

Turning the power on and off

Press the [ ] power button for one second. The power button LED lights when the unit is on. The THR-II Wireless power button LED lights green while charging, otherwise red.

Checking the battery level (THR-II Wireless only)

Press the [ ] button for less than one second. Battery capacity is displayed in four levels: 3, 2, 1, and L (Low).

Battery level indicators: Battery full [●●●●], No battery remaining [●]

Charging the built-in battery (THR-II Wireless only)

Connect the power adaptor to the DC IN jack. The power button LED lights green while charging.

NOTICE: When used in extreme temperatures, charging may not be possible. Charge the battery every six months to maintain functionality.

Charging the Wireless Transmitter (THR-II Wireless only)

Connect a compatible Wireless Transmitter to the [INPUT] jack. The transmitter starts charging automatically. If you disconnect and want to resume charging, wait at least two (2) seconds before reconnecting.

NOTICE: After charging, unplug the transmitter. If the THR-II Wireless is off and the adapter is connected, the transmitter charges. However, the THR-II Wireless defaults to stopping power to the transmitter when charging is finished. To avoid transmitter battery depletion, turn off the THR-II Wireless's ECO setting.

Changing the Wireless Transmitter's ECO setting

1. Switch on the THR-II Wireless.

2. Switch off the THR-II Wireless while holding the [TAP/TUNER] button.

Auto Power Off Function

To prevent unnecessary power consumption, the THR-II features an Auto Power Off function that automatically turns the power off if the unit is not operated for approximately 20 minutes; however, you can change the setting.

NOTICE: If you do not want the power to turn off automatically when a computer is connected, disable the Auto Power Off function.

Enabling or disabling the Auto Power Off Function

Hold down [USER MEMORY] buttons [1], [2], and [4] simultaneously. The LED display indicates the status.

Diagram Description: Shows LED indicators for "Auto Power Off function is enabled" and "Auto Power Off function is disabled."

NOTICE: Depending on the THR-II status, power may not turn off automatically. Always turn off the power manually when not in use.

NOTE: When the Auto Power Off function switches on or off successfully, the setting result is displayed, and the tuner LED lights at the same time. The setting time is approximate. To turn the power on after Auto Power Off has been executed, press the [ ] power button.
