5 Thanks to 32-bit high-precision processing at a 96 kHz sampling rate from input to output, the MD-500

gives you stunningly high-quality modulation eect.

5 With an easily readable screen and an independent [TAP/CTL] switch, it delivers both high

functionality as well as ease of use during live performances.

5 Standard eects such as chorus, anger, and phaser have been enhanced using cutting-edge

Boss technology. The MD-500 provides a total of 12 modulation eects, including models of the Boss CE-1 and scanner vibrato.

5 The memory function lets you store and recall 297 dierent setups from internal memory. 5 The MD-500 provides “simul mode” which lets you use two eects simultaneously, and an “insert

loop function” which lets you shape your sound in conjunction with an external eect unit.

5 By connecting the MD-500 via a USB cable or MIDI cables, you can switch sounds and control

parameters in synchronization with your computer DAW or an external MIDI device.

Getting Ready

Installing the Batteries

Install four alkaline batteries (AA, LR6) in the battery compartment located on the bottom of the 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.

* If you handle batteries improperly, you risk explosion and uid 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” (separate sheet “USING THE UNIT SAFELY” and Owner’s manual (p. 30)).

* We recommend that you keep batteries installed in the unit even though you’ll be powering it

with the AC adaptor. That way, you’ll be able to continue a performance even if the cord of the AC adaptor gets accidently disconnected from the unit.

* “BATTERY LOW” will appear on the display if the batteries are low. Replace them with new ones.

Attaching the Rubber Feet

You can attach the rubber feet (included) if necessary. Attach them in the locations shown in the illustration.

Connecting the Equipment

* To prevent malfunction and equipment failure, always turn down the volume, and turn o all

the units before making any connections.

USB (O) port

Use a commercially available USB 2.0 cable to connect this port to your computer.

You can synchronize with a DAW via MIDI.

MIDI IN, OUT connectors

Connect an external MIDI device here.

You can synchronize with an external MIDI device via MIDI.

MIDI device

DC IN jack

Accepts connection of an AC Adaptor (PSA-S series; sold separately). By using an AC Adaptor, you can play without being concerned about how much battery power you have left.

* Use only the specied AC adaptor (PSA-S series; sold

separately), and connect it to an AC outlet of the correct voltage. Do not use any other AC adaptor, since this may cause malfunction.

* If the AC adaptor is connected while power is on, the power

supply is drawn from the AC adaptor.

Getting Ready

INPUT A/MONO, B jacks

Connect your electric guitar, or another instrument or eect unit, to these jacks.

* Use the INPUT A/MONO jack and B jack when connecting a stereo-

output eects unit. Use only the INPUT A/MONO jack if you’re using a mono source.

Turning the power on/o

The INPUT A/MONO jack doubles as the power switch. Power to the unit is turned on when you plug into the INPUT A/MONO jack; the power is turned o when the cable is unplugged.

When powering up:

Turn on the power to your amp last.

When powering down:

Turn o the power to your amp rst.

CTL 1, 2/EXP jack

You can control various parameters by connecting a footswitch (FS-5U, FS-5L, FS-6, FS-7: sold separately) or an expression pedal (such as the EV-30, Roland EV-5; sold separately) to the CTL 1, 2/EXP jack (p. 25).

If you experience problems connecting with your DAW

Normally, you don’t need to install a driver in order to connect the MD-500 to your computer. However, if some problem occurs, or if the performance is poor, using the BOSS original driver may solve the problem.

In this case, setting “USB MODE” to “VENDOR” on the MD-500, install the driver on your personal computer.

For details on downloading and installing the BOSS original driver, refer to the BOSS website. For further details, refer to the Readme.htm le that comes with the download.

Troubleshooting

Problem Items to check Action

Power does not turn on

No sound is output

Is your guitar correctly connected to the INPUT A/MONO jack? Could the batteries be low? Install fresh batteries. Is the specied PSA-S series AC adaptor connected correctly?

Could the insert loop function be assigned?

Is the SYSTEM: FSW MODE (p. 22) setting correct?

Check the connection once again.
