What are the panel descriptions and functions of the BOSS RT-2?
The panel of the BOSS RT-2 features several jacks, knobs, switches, and indicators, each with a specific function:
| Part | Name | Explanation |
|---|---|---|
| 1 | DC IN jack | Use this jack to connect a separately sold AC adaptor (PSA series). Using an AC Adaptor allows you to play without concern for battery power. Only use the specified AC adaptor connected to an AC outlet of the correct voltage. If connected while the power is on, the power supply is drawn from the AC adaptor. |
| 2 | CHECK indicator | This indicator shows if the effect is on/off, the rotary speed, and the battery state. It lights up when an effect is ON. It lights red for FAST speed and green for SLOW speed. The brightness dims as the battery lowers. |
| 3 | OUTPUT A (MONO) jack, OUTPUT B jack | Connect these jacks to your amp or monitor speakers. Use only OUTPUT A (MONO) for mono use. For stereo, use both OUTPUT A and OUTPUT B jacks. When both are connected, the effect is produced according to the OUTPUT MODE settings. |
| 4 | INPUT A (MONO) jack, INPUT B jack | Connect your guitar, bass, keyboard, or other effect unit. For mono use, connect to INPUT A (MONO) only. Use both jacks for stereo input. The INPUT A (MONO) jack also acts as the power switch; power turns on when a plug is inserted. |
| 5 | SPEED jack (CTL/EXP jack) | Connect a footswitch or expression pedal here. As a CTL jack, it connects to a footswitch (FS-5U, FS-6, FS-7) to control SLOW/FAST switching or the brake feature. As an EXP jack, it connects to an expression pedal (EV-30, Roland EV-5, etc.) to continuously change effect settings. |
| 6 | Pedal switch | Turns the effect on/off, or switches between rotor speeds (SLOW/FAST). There are four types of pedal switch functions you can set. |
| 7 | [FAST SPEED] knob | Adjusts the rotation speed of the rotor when switched to FAST. |
| 8 | [SLOW SPEED] knob | Adjusts the rotation speed of the rotor when switched to SLOW. |
| 9 | [LEVEL] knob | Adjusts the volume when the effect is on. |
| 10 | [DRIVE] knob | Adjusts the amount of distortion. When the [MODE] switch is set to “III”, distortion and volume are emphasized. The [DRIVE KNOB] switch toggles the function of this knob. |
| 11 | [MODE] switch | Selects one of three rotary sound modes: I (standard Leslie 122 sound), II (wider range based on mode I), and III (new dimension with stronger rotation and deeper distortion). |
| 12 | VIRTUAL ROTOR | Shows the rotary speaker effect by the movement of the indicator lights. The red light indicates the treble rotor rotation, and the blue light indicates the bass rotor rotation. |
| 13 | [RISE/FALL TIME] knob | Adjusts the rate of change when switching between SLOW and FAST speeds. SLOW position means a slower switching time; FAST position means a faster switching time. |
| 14 | [DRIVE KNOB] switch | Toggles the function of the [DRIVE] knob between DRIVE (adjusts distortion) and BALANCE (adjusts the balance between the treble and bass rotors). The most recent values are stored in memory. |
How do I replace the battery in the BOSS RT-2?
Batteries should always be installed or replaced before connecting any other devices to prevent malfunction and damage. Use an alkaline battery if running on battery power. Follow these steps:
1. Hold down the pedal and loosen the thumbscrew, then open the pedal upward. You do not need to remove the thumbscrew completely.
2. Remove the old battery from the battery housing, and disconnect the snap cord connected to it.
3. Connect the battery snap to the new battery, and place the battery inside the battery housing. Be sure to carefully observe the battery’s polarity (+ versus -).
4. Slip the coil spring onto the spring base on the back of the pedal, and then close the pedal. Carefully avoid getting the snap cord caught in the pedal, coil spring, or battery housing.
5. Finally, hold down the pedal while tightening the thumbscrew into the guide bush hole.
How do I turn the power on for the BOSS RT-2?
Before turning the unit on, always turn the volume down on your connected equipment.
1. Connect a plug to the INPUT A (MONO) jack. This turns on the RT-2. The unit turns on with the effect off (the CHECK indicator will be unlit). The CHECK indicator briefly lights up when the unit is turned on.
2. Turn on your amp or other audio equipment.
How do I turn the power off for the BOSS RT-2?
1. Turn off your amp or other audio equipment.
2. Unplug the cable from the INPUT A (MONO) jack. This turns off the RT-2.
How do I use an external footswitch with the BOSS RT-2?
You can connect a footswitch (like a BOSS FS-5U, FS-6, or FS-7) to the SPEED jack (CTL/EXP jack) to switch between SLOW/FAST and operate the brake. When a footswitch is connected, the pedal switch on the RT-2 is limited to switching the effect on/off.
The footswitch functions are as follows:
| Footswitch | CTL1 function | CTL2 function |
|---|---|---|
| FS-5U | Toggle between SLOW/FAST | — |
| FS-5U x 2, FS-6, FS-7 | Toggle between SLOW/FAST | Operate the brake |
Operating the brake:
1. Press footswitch CTL2. The rotor stops rotating. The time it takes to stop depends on the [RISE/FALL TIME] switch position (slower on SLOW, faster on FAST).
2. To release the brake, press footswitch CTL2 again.
How can I control parameters on the BOSS RT-2 with an expression pedal?
You can use an expression pedal (like a Roland EV-30 or EV-5) connected to the SPEED jack to control rotation speed, LEVEL, DRIVE, or BALANCE. The factory setting controls rotation speed. To change the assigned parameter:
1. Turn off the RT-2 by unplugging the cable from the INPUT A (MONO) jack.
2. Turn the [FAST] knob to the maximum (MAX) setting.
3. Turn all other knobs besides the [FAST] knob to the minimum (MIN) setting.
4. Set the [MODE] switch to the “III” position.
5. Turn on the power by connecting a plug to the INPUT A (MONO) jack while holding down the pedal switch. The CHECK indicator will blink, and the unit enters settings mode.
6. Use the [DRIVE] knob to select the parameter to assign. The VIRTUAL ROTOR display changes to indicate the selected parameter:
| Virtual rotor (red) display | Explanation |
|---|---|
| Lights up at the 12 o’clock position | Controls the LEVEL. |
| Lights up at the 3 o’clock position | Controls the DRIVE. |
| Lights up at the 6 o’clock position | Controls the BALANCE. |
| Lights up at the 9 o’clock position (factory setting) | Controls the rotation speed of the rotary speaker. The CHECK indicator lights up orange when speed is being controlled. |
7. Use the [SLOW] knob to set the minimum value (heel position). This cannot be set if you selected rotation speed in step 6.
8. Use the [FAST] knob to set the maximum value (toe position). This cannot be set if you selected rotation speed in step 6.
9. Press the pedal switch. The CHECK indicator rapidly blinks red, and the setting is stored in memory. The device is ready for normal use after 2-3 seconds.
How can I change the pedal switch behavior on the BOSS RT-2?
You can change how the pedal switch works to suit your playing style. The factory setting (Type 1) toggles the effect on/off with a press, and toggles SLOW/FAST with a long-press. To change this:
1. Turn off the RT-2 by unplugging the cable from the INPUT A (MONO) jack.
2. Turn the [SLOW] knob to the maximum (MAX) setting.
3. Turn all other knobs besides the [SLOW] knob to the minimum (MIN) setting.

What should I do if the power does not turn on for my BOSS RT-2?
If the power on your BOSS RT-2 does not turn on, check the following:
• Is a plug connected to the INPUT A (MONO) jack? Make sure the plug is properly connected, as this acts as the power switch.
• The battery may be nearly depleted. Replace the battery with a new one. If using AC power, make sure the AC adaptor (sold separately) is properly connected.
• Is the specified PSA series AC adaptor (sold separately) connected correctly? Make sure the AC adaptor is properly connected.
Why is the CHECK indicator on my BOSS RT-2 dim or repeatedly lighting up and going dark?
This usually indicates that the battery is nearly depleted. Replace the battery with a new one. If you are using AC power, make sure that the AC adaptor (sold separately) is properly connected.
Why is there no sound coming from my BOSS RT-2?
If you are not getting any sound from your pedal, check the following:
• Have the output mode settings been made correctly? Check the output mode settings and the OUTPUT jack connection.
• Is your output device correctly connected to the OUTPUT jack?
Why does the sound not distort when I turn the [DRIVE] knob on my BOSS RT-2, or why is the sound muffled or thin?
The [DRIVE KNOB] switch might be set to the “BALANCE” position. Set the [DRIVE KNOB] switch to the “DRIVE” position and then turn the [DRIVE] knob.
Why is the output sound from my BOSS RT-2 noisy?
If the output sound is noisy, the battery may be nearly depleted. Replace the battery with a new one. If you are using AC power, make sure that the AC adaptor (sold separately) is properly connected.
