Panel Descriptions

Precautions When Connecting

• To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
• Do not use connection cables that contain a built-in resistor.
• 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.

When powering up
Turn on the power to your guitar amp last.

When powering down
Turn off the power to your guitar 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.

About Output

• Connect to the OUTPUT jack only
  The direct sound + delay sound is output.

• Connect to the OUTPUT jack and the DIRECT OUT jack
  The delay sound is output from the OUTPUT jack, and the direct sound is output from the DIRECT OUT jack.

• Connect to the SEND/RETURN jacks of a guitar amplifier
  If you’re using this unit in a parallel-connected effect loop, insert a dummy plug into the DIRECT OUT jack so that only the delay sound is output to the RETURN jack.

Using the Tempo Delay

By pressing the pedal switch or an external foot switch several times in rhythm with your song, you can set the delay time to match the tempo of the song (tempo delay)

MEMO

• The delay time range is 133–800 msec (BPM = 75–300).
• The delay time specified by tempo input is maintained until you operate the [TIME] knob.

Using the pedal switch

• If a foot switch (sold separately) is connected to the TEMPO jack, you can’t use the pedal switch to enter the tempo.

  1. Use the [MODE] knob to specify the note value that will be the basis of the delay time.
  2. Hold down the pedal switch for two seconds or longer.
     The CHECK indicator is lit green, and now you can use the pedal switch to enter the tempo.

• Tempo entry is not possible if the [MODE] knob is set to “SHORT LOOP.” 3. Press the pedal switch at quarter-note intervals in synchronization with the tempo of the song.
  According to the tempo that you enter, the delay time is set so that it is the length of the note value that you specified with the [MODE] knob.
  The CHECK indicator blinks at the specified tempo.

  4. To finish inputting the tempo, hold down the pedal switch for two seconds or longer.

Using an external footswitch
Basic operation is the same as when using the pedal switch.

1. Connect a footswitch (sold separately: FS-5U, FS-6, or FS-7) to the TEMPO jack.
2. Use the [MODE] knob to specify the note value that will be the basis of the delay time.
3. Press the footswitch at quarter-note intervals in synchronization with the tempo of the song.
   The delay time is set, and the CHECK indicator blinks at the specified tempo.
