Product Information

Guitar Amplifier

The guitar amplifier is an electronic device that amplifies the sound of an electric guitar or other musical instruments. It features a top panel with various controls and jacks, including a GUITAR jack/STEREO IN, AMP TYPE knob, MEMORY button, GAIN knob,VOLUME knob, EQUALIZER with BASS, MIDDLE, and TREBLE knobs, EFFECTS knob with various effects including CHORUS, FLANGER, PHASER,TREMOLO, HEAVY OCTAVE, and OFF, and a DELAY/REVERB knob with various effects including OFF, DELAY, REVERB, and SPRING.

Panel Descriptions

1. GUITAR jack/STEREO IN, R jack: This jack is used to connect your electric guitar, mic, multi-effect unit, effect units with stereo outputs or other such devices. When inputting in stereo, set the amp type to STEREO IN. If you connect the L jack from your device to this unit using the STEREO IN setting, only the L-side output is heard.
2. AMP TYPE knob: This knob is used to select the amp type. The available options are ACOUSTIC SIM, JC CLEAN, US COMBO, BRIT COMBO, HI-GAIN STACK, METAL STACK, EXTREME, MIC, and STEREO IN. Each amp type has a unique sound and is modeled after a specific amplifier type.
3. MEMORY button: This button is used to store three different sets of knob configurations for each amp type.
4. GAIN knob: This knob is used to adjust the gain or amount of distortion in the sound.
5. VOLUME knob: This knob is used to adjust the volume before equalization and effects are applied.
6. EQUALIZER: This section has three knobs, including BASS, MIDDLE, and TREBLE. These knobs are used to adjust the sound level of the low-frequency range, middle-frequency range, and high-frequency range, respectively.
7. EFFECTS knob: This knob is used to switch between effects such as chorus or flanger, depending on the knob’s position. The available options are OFF, CHORUS, FLANGER, PHASER, TREMOLO, and HEAVY OCTAVE.
8. DELAY/REVERB knob: This knob is used to switch between effects such as delay or reverb, depending on the knob’s position. The available options are OFF, DELAY, REVERB, and SPRING.

Operating on Battery Power

This unit can be used with alkaline batteries or rechargeable Ni-MH batteries.

• Times are approximate, and differ depending on the conditions of use.
• If you handle batteries improperly, you risk explosion and fluid leakage. Make sure that you carefully observe all of the items related to batteries that are listed in “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (the leaflet “USING THE UNIT SAFELY” and the Owner’s Manual p. 12).
• When operating on battery power, the unit’s POWER indicator blinks if the batteries are nearly depleted. Replace the batteries as soon as possible.
• Sounds may distort easily or cut off when played at high volume as the battery power is nearly depleted, but this is not a malfunction. In such instances, replace the batteries or use the AC adaptor included with the unit.

Installing the Batteries

1. Remove the battery cover on the bottom of this unit.
   When turning the unit over, be careful so as to protect the buttons and knobs from damage. Also, handle the unit carefully; do not drop it.

2. Insert the batteries, making sure they face the right way.

Turning the Power On/Off

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.

1. Make sure that the [MASTER] knob of this unit, as well as the volume of any connected devices, are set to minimum.
2. Turn on the power of this unit.
3. Turn on the power of the devices connected to the LINE OUT and PHONES/REC OUT jacks.
4. Adjust the volume levels of the devices.
   Before switching off the power, lower the volume on each of the devices in your system and then turn off the power of this unit (the reverse of when you switch this unit on).

Useful Functions

Using the Memories
You can use the memory feature to store the current settings of the knobs, in three different sets of knob configurations for each amp type.

Storing the Knob Settings to Memory
Here’s how to store the current knob positions to memory.

1. Press the [MEMORY] button to select the memory where the settings are to be stored.
   Button color or state| Explanation
   ---|---
   Unlit (off)| The amp produces sound using the current knob settings.
   Green (memory 1)| The amp produces sound using the knob positions (settings) stored in memory.
   Red (memory 2)
   Orange (memory 3)

Each press of the button cycles through the memory numbers (greenÓredÓorangeÓunlitÓgreen), and the LED color changes accordingly.

2. Turn the knob to the setting you like.
3. Hold down the [MEMORY] button for several seconds.
   The [MEMORY] button blinks.
   Once the settings are stored, the [MEMORY] button lights up continuously.

NOTE

• Once you store settings in a memory, any existing settings that were stored in that memory are lost.
• The settings you store can be lost if you take the unit in for repair or due to equipment failure, incorrect operations or other such causes. To avoid the nuisance of losing your data, back up the important data you’ve stored in the unit, or write the settings down by hand. You can use the dedicated software (p. 4) or an app on your mobile device (p. 9) to back up the settings stored on this unit.

Recalling a Memory
Here’s how to recall the knob settings that are stored in memory.

1. Turn the [AMP TYPE] knob to select the amp type.
2. Press the [MEMORY] button to select the memory to recall.
   This changes the unit’s knob settings to the settings stored in the memory you selected.
   Note that the volume may change abruptly when switching between memories, depending on the settings stored in the memories.

MEMO

•  If you move a knob after recalling a memory, the setting or value for that knob changes to the knob’s current position.
  Once the knob’s actual position matches the position that’s stored in memory, the [MEMORY] button immediately goes dark.

• You can connect a footswitch (FS-5U, FS-6, FS-7; sold separately) to the FOOT SW jack to turn the memory on/off (green (memory 1) Ð unlit) (p. 5).
  You can also use the dedicated software (p. 4) or an app on your mobile device (p. 9) to switch between green (memory 1) and red (memory 2), switch between different amp types and otherwise freely customize the settings.

Using the Looper

You can use the looper by connecting a footswitch (FS-5U, FS-6, FS-7; sold separately) to the FOOT SW jack.
You can record up to 90 seconds (in mono) and play back the recorded section over and over. You can also layer additional performances with the recording as it plays back (overdubbing). This lets you create real-time backing performances on the fly.
The factory default setting is set to a maximum of 45 seconds (stereo). With the dedicated software (p. 4) or mobile device app (p. 9), you can select up to a maximum of 90 seconds (mono).

• Once you reach the maximum available recording time, the unit automatically switches to playback mode.
• Anything you record is lost once you turn off the power.

LOOPER indicators

Using This Unit with Other Mobile Devices (i-CUBE LINK)
With the “i-CUBE LINK” feature, you can connect your mobile device with the included mini cable (4-pole) and play back audio from that device, at the same time that the sound inputted into this unit is sent to the mobile device.
Use this to play back or record the sound inputted into this unit on your mobile device by means of an app, or to livestream your performance.

Wireless Connection with a Mobile Device

Here’s what you can do when the BT-DUAL (sold separately) is connected to the DUAL CUBE LX.

• Play music wirelessly from a mobile device
• Edit the effects using an app on your mobile device
• Control the volume and other parameters from an EV-1-WL wireless MIDI expression pedal (sold separately)
• Note that the DUAL CUBE LX does not offer Bluetooth functionality.
  You’ll need to attach the BT-DUAL (sold separately) to use Bluetooth.

Attaching the BT-DUAL

Attach the BT-DUAL to the Bluetooth ADAPTOR connector of the DUAL CUBE LX.

1. Power down the DUAL CUBE LX and unplug the AC adaptor from the AC outlet.
2. Remove the cover and screw from the Bluetooth ADAPTOR connector on the rear panel.
3. Attach the BT-DUAL and fasten the screw that you removed in step 2 in place.

NOTE

• Be sure to use only the screw that was originally mounted on the Bluetooth ADAPTOR connector. If you use a different screw, the unit may malfunction.
• Do not touch any of the printed circuit pathways or connection terminals.
• After you have attached the BT-DUAL, check again whether it is properly installed.
