Adjusts the echo effect applied to the microphone (p. 15) .

 

 

Turn the MT-90U speakers on and off.

 

Here is where you can connect an external instrument, 
such as an electric piano, using an audio cable (sold 
separately) (p. 54).

 

Wrap the AC adaptor cord around this hook. By doing 
so, you can avoid placing undue stress on the DC In jack 
and prevent the loss of power should you accidentally 
pull on the AC adaptor’s cord.

 

Here is where you can connect an external MIDI device 
using a MIDI cable (sold separately) (p. 54).

 

Connect the pedal switch (sold separately). Once 
connected, you can start and stop song playback using 
the pedal (p. 53).

 

Allows you to connect the MT-90U to a computer using a 
USB cable. Once connected, you can receive MIDI data 
through your computer.

 

Depending on the circumstances of a particular setup, 
you may experience a discomforting sensation, or 
perceive that the surface feels gritty to the touch when 
you touch this device, microphones connected to it, or 
the metal portions of other objects, such as guitars. This 
is due to an infinitesimal electrical charge, which is 
absolutely harmless. 
However, if you are concerned about this, connect the 
ground terminal (see figure) to an external ground. 
When the unit is grounded, a slight hum may occur, 
depending on the particulars of your installation. If you 
are unsure of the connection method, contact your 
nearest Roland Service Center, or an authorized Roland 
distributor, as listed on the “Information” page.

Do not connect the MT-90U near:

• Water pipes (may result in shock or electrocution)

• Gas pipes (may result in fire or explosion)

• Telephone-line ground or lightning rod (may be 

dangerous in the event of lightning)
