Basic Operation
1. Connections
Make sure each device is turned off before connecting any ad-
ditional equipment. If an operation is inadvertently performed,
the speaker system and other devices may be damaged or mal-
function.
1.
Connecting the AC adapter
Connect the included AC adapter to the DC12V jack.
Only use the included AC adapter.
2.
Connecting the output destination
Connect the powered monitor speaker or mixer to the SIG-
NAL OUT jack.
3.
Connecting headphones
When using headphones, insert the headphone plug into
the PHONES jack.
4.
Connecting guitars and microphones to the SIGNAL IN
jack
When using an external signal processor, connect the gui-
tar or microphone to the SIGNAL IN jack.
For details, refer to "Using the External Signal Processor
(ESP)" in the original Owner's Manual.
2. Turning on the device
1.
Turn the VOLUME knob clockwise.
2.
After a click, the STANDBY ON LED lights up and the de-
vice is turned on.
TIP If the auto power off function is disabled, the LED blinks a few
times.
3.
To turn off the device, turn the VOLUME knob counter-
clockwise until it clicks and the LED turns off.
TIP If the AC adapter is disconnected while the MS-20M Kit is turned
on or if the auto power off function has been enabled, the device
may have turned off without the VOLUME knob in the off posi-
tion. Before turning on the MS-20M Kit again, you'll have to turn
the VOLUME knob fully counterclockwise to turn it off.
Auto power off function
The MS-20M is automatically turned off if none of the following
operations are performed for 4 hours.
• Note On via MIDI IN or USB MIDI
• Input to TRIG IN
TIP The auto power off function is enabled as a factory setting (de-
fault).
To disable the auto power off function
1.
Check that no patch cords are connected to any jack.
2.
Connect a patch cable to only the WHITE NOISE OUT
jack. Do not connect the other end of the cable to anything.
3.
While holding down the TRIG SW button, turn on the MS-
20M.
When the function is disabled, the STANDBY ON LED
blinks a few times, then remains lit, and then the device
returns to normal operation.
TIP The setting for the auto power off function is saved, even when
the MS-20M is turned off.
TIP When changing the setting, do not turn off the MS-20M before
the STANDBY ON LED lights up. Otherwise, data may be cor-
rupted or the device may be damaged.
To enable the auto power off function again
Connect a patch cable to only the PINK NOISE OUT jack, and
then hold down the TRIG SW button while turning on the MS-
20M.
When the function is enabled, the STANDBY ON LED lights up,
without blinking, and then the device returns to normal opera-
tion.
3. Producing sounds
Basic settings
Refer to "Normal Setting" (→p.83) and adjust the knobs.
Producing a sound
Press the TRIG SW button to hear a tone.
To adjust the volume, turn the VOLUME knob.
Adjusting the knobs
Turn the CUTOFF FREQUENCY knob of the LOWPASS FIL-
TER counterclockwise to round off the sound. In addition, adjust
the timbre by using the OSCILLATOR 1 knob to change the
waveform to the triangle wave.
Filter setting
The VCFs (high-pass filter & low-pass filter) of the original MS-
20 are differentiated into the earlier and later filters, depending
on the production date.
Since the circuitry differs between these two filter types, they
have different sound quality characteristics, although their fre-
quency characteristics are similar.
The MS-20M is equipped with both types of filters for you to
select as desired.
The filter type is selected with the FILTER TYPE REV.1/REV.2
switch. When the switch is set to REV.1, the filter is the earlier
one. When set to REV.2, the filter is the later one.
