Panel Descriptions
Top Panel
- Graphic equalizerA ten-band graphic equalizer that provides ±15 dB of adjustment in the range of 30 Hz–12.8 kHz (the center frequency varies according to type).
- [LEVEL] sliderCompensates for the volume difference when switching between normal and effect sound.
- DisplayVisually indicates the state of the equalizer, or shows memory numbers or parameters.
- [CHANNEL] buttonSwitches the display between showing the states of channels A or B, or showing the memory number.Preventing accidental operation (panel lock)By long-pressing the [CHANNEL] button you can toggle between enabling operation of the equalizer and buttons (unlocked) or disabling operation (locked).If you operate the unit while it is locked, the display indicates “LOCKED.
- CHANNEL indicatorIndicates the currently selected channel.When the indicator is unlit, the display shows the memory number.* If the LINK parameter (p. 9) is ON, indicators A and B are both lit.
- [MEMORY] buttonSwitches or saves memories (MANUAL, 1–127) (Check down below).The memory is switched each time you press the[MEMORY] button.
- MEMORY indicatorIndicates the currently selected memory.If a memory 5–127 is selected, the indicator is unlit.
- [ON/OFF] switchSwitches the effect on/off.
- MEMORY] switchSwitches memories (Check down below).
MEMO
- The function of the footswitch can be changed by “SW FNC” (ON/OFF SW FUNCTION), “MEM FNC” (MEMORY SW FUNCTION).
- Regardless of the function of the footswitch, you can hold down the [MEMORY] button and press the [MEMORY] switch to increment the memory number or press the [ON/OFF] switch to decrement the memory number.
Rear Panel (Connecting Your Equipment)
- To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
A. INPUT (A/MONO, B) jacks
Connect your guitar, bass, or effect unit here.Use the A and B jacks if connecting an effect unit thathas stereo output. Use only the A jack if using this unitin mono.
Turning On/Off the PowerThe INPUT A jack also operates as the power switch. The power turns on when you insert a plug into the INPUT A jack.
When powering upPower-up equipment such as your guitar amp last.When powering downPower-down equipment such as 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.
B. OUTPUT (A/MONO, B) jacksConnect this jack to your amp or monitor speakers.Use only the OUTPUT A jack if using this unit in mono.Even sound that is input in stereo is output in mono.C. CTL 1, 2/EXP jackUsing the jack as CTL 1/2You can connect a footswitch (sold separately: FS-5U, FS-6, FS-7) and use it to switch memories or channels (Check down below)
Using the jack as EXPYou can connect an expression pedal (sold separately:EV-30, Roland EV-5, etc.) and use it to control the volume of the effect sound.
* Use only the specified expression pedal. By connecting any other expression pedals, you risk causing malfunction and/or damage to the unit.
D. DC IN jackAn AC adaptor (sold separately: PSA-S series) can be connected to this jack.
- Use only the specified AC adaptor (sold separately: PSA-S series) and plug it into 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.
Side Panel (Connecting Your Equipment)
E. MIDI jacksUse a TRS/MIDI connecting cable (sold separately:BMIDI-5-35) to connect an external MIDI device. You can use an external MIDI device to switch the memories of this unit.
- Do not connect an audio device here. Doing so will cause malfunctions.
F. USB portConnect your computer using a commercially available USB cable that supports USB 2.0.
- Do not use a micro USB cable that is designed only for charging a device. Charge-only cables cannot transmit data.
- This is used only for program updates.
Saving and Switching Memories
Saving to Memory
Here’s how to save equalizer settings that you edited.
- Long-press the [MEMORY] button.The display indicates “WRITE TO:.”
- Press the [MEMORY] switch or the [ON/ OFF] switch to select the save-destination (MAN, 1–127).You can also select the save-destination by pressing the [MEMORY] button.If you decide to cancel, press the [CHANNEL] button.
- Long-press the [MEMORY] button to confirm the save-destination.The memory is saved.
Switching Memories
Here’s how to recall a saved memory.
- Press the [MEMORY] button to select a memory.Each time you press the button, you cycle through the memories in the order of “MAN (manual) → 1 → 2 → 3→ 4 …127→ MAN…”You can also switch memories by holding down the [MEMORY] button and press the [MEMORY] or [ON/ OFF]switch.MEMOBy changing the EXT FROM (EXTENT FROM), EXT TO (EXTENT TO) settings (Check down below) you can specify the range within which memories are switched.
What is “MAN” (manual)?If STRUCT (STRUCTURE)=PARA and LINK=ON, selecting “MAN” applies the equalizer with settings that correspond to the position of the graphic equalizer’s sliders.For other settings, the settings saved in MAN are recalled.
Basic Operation
- Press the [CHANNEL] button and [MEMORY] button simultaneously.You enter menu mode.
- Press the [CHANNEL] button or [MEMORY] button to select a parameter.
- Press the [ON/OFF] switch or [MEMORY] switch to change the value.
- Press the [CHANNEL] button and [MEMORY] button simultaneously.You exit menu mode.
