Function

1

DC IN jack

Accepts connection of an AC Adaptor (PSA series; sold separately).

  • Use only the specified AC adaptor (PSA series; sold separately), and connect it to an AC outlet of the correct voltage.
  • If the AC adaptor is connected while power is on, the power supply is drawn from the AC adaptor.

2

CHECK indicator

This indicator shows whether the effect is ON/OFF, and doubles as the tempo and battery check indicator.

The indicator lights up red when the effect is on and lights up green when the effect is off. The indicator also blinks in time with the tempo.

  • The brightness of the CHECK indicator (LED) will dim as the battery lowers. Replace the battery when the LED is dim or does not light. For details on how to replace, refer to “Changing the Battery”.

3

OUTPUT A (MONO), OUTPUT B jacks

Connect these jacks to your amp or monitor speakers.

Use only the OUTPUT A (MONO) jack if using this unit in mono.

If you’re using a stereo setup, use the OUTPUT A (MONO) and OUTPUT B jacks.

When you connect to both the OUTPUT A (MONO) and OUTPUT B jacks, an effect is produced according to the OUTPUT MODE settings. For details, refer to “Selecting Various Ways of Outputting the Effect Sound (OUTPUT MODE)”.

4

INPUT A (MONO), INPUT B jacks

Connect your guitar, bass, or effect unit here.

Use only the INPUT A (MONO) jack if using this unit in mono. Use the INPUT A (MONO) jack and INPUT B jack when connecting to an effect unit with stereo outputs.

  • The INPUT A (MONO) jack doubles as the power switch. The power turns on when you insert a plug into the INPUT A (MONO) jack.

5

 CTL/EXP jack

  • Using the jack as EXP

    Connect an expression pedal (EV-30, Roland EV-5, etc.; sold separately) to continuously change the effect settings for the expression pedal’s pushed-up (horizontal) position and for the pushed-down (slanted) position.

    For more about function settings, refer to “Controlling the Knobs Using an Expression Pedal (EXP FUNCTION)”.

6

 Pedal switch

  • On/off switch

    Turns the effects on/off.

    Long-press this switch to use tap tempo. When you do this, the CHECK indicator alternately lights up red and green.

  • Tap tempo

    You can set the tempo of the slice pattern with the timing at which you depress the pedal switch.

    • The tempo can’t be set using the SL-2 if this device is receiving MIDI clocks from an external device, since this device is synchronized with the tempo of the external device.

    1. Hold down the pedal switch for at least two seconds (the CHECK indicator blinks red/green).

    2. Press the pedal switch at quarter-note intervals in synchronization with the tempo of the song.

      You can use the [TEMPO] knob to control the level of the effect sound.

    3. Hold down the pedal switch for at least two seconds to complete the setting.
7
[BALANCE] knob

Adjusts the balance between the effect sound and the direct sound.

Turn the knob all the way clockwise to hear only the effect sound, and turn the knob all the way counterclockwise to hear only the direct sound.
8 [ATTACK] knob Adjusts the volume of the attack waveform for the slice pattern.
9
[VARIATION] knob Selects the pattern variations.
10 Type knob

Switches between different slicer types.

SINGLE (1, 2)

A type that uses a single slicer effect.

DUAL (3, 4)

A type that uses two slicer effects.

TREMOLO (5)

A tremolo pattern.

HARMONIC (6)

A modulated slice pattern.

SFX (7, 8)

Slice patterns to which various effects are applied.
11
[TEMPO] knob

Sets the tempo (BPM 40–300).

  • The tempo can’t be set using the SL-2 if this device is receiving MIDI clocks from an external device, since this device is synchronized with the tempo of the external device.
12 [DUTY] knob

Adjusts the ratio (sound length) with which the slice pattern sounds.

Turn the knob counterclockwise to make the sound shorter (). Turn the knob clockwise to make the sound longer ().
13
MIDI IN connector

This connector receives timing clocks, start/continue/stop messages and control change messages from an external device.

  • Use TRS/MIDI connecting cables (BMIDI series, BCC series; sold separately) to connect this unit to an external MIDI device.
  • Do not connect to audio devices. Doing so may cause a malfunction.
14 PATTERN IMPORT port

Connect your computer to the SL-2 with a USB cable. You can swap slice patterns by using the dedicated app, “BOSS TONE STUDIO for SL-2”.

For details, refer to “Using BOSS TONE STUDIO for SL-2”.
  • Do not use connection cables that contain a built-in resistor.
  • To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.


Turning the power on/off

Once everything is properly connected, be sure to follow the procedure below to turn on their power. If you turn on equipment in the wrong order, you risk causing malfunction or equipment failure.

Turning the Power On

Turn on the power to your amp last.

Turning the Power Off

Turn off the power to your amp first.

  • Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
