Roland RD-300SX 用户手册

 

fig.00b-03

 

This connector lets you use a USB cable to connect your 
computer to the RD-300SX (p. 50).

 

Connecting the pedal switch (DP series) provided with the RD-
300SX to the DAMPER jack allows you to use the switch as a 
damper pedal. 

With an optional expression pedal (such as the EV series or 
other model) connected to the CONTROL jack, you can then 
assign a variety of functions to the pedal (p. 39, p. 40).

 

Used for connecting external MIDI devices and for transmission 
of MIDI messages (p. 12, p. 47).

 

Provide output of the audio signals. These are connected to an 
amp or other device. For monaural output use the L/MONO 
jack (p. 12).

 

Even when headphones are connected, sound will still be 
output from the output jacks.

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 (p. 11) with 
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 the nearest 
Roland Service Center, or an authorized Roland distributor, as 
listed on the “Information” page.

 

• 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)
