amplifier, or the left input of a stereo power amp. If the RP21D is to be used in a mono application, set the Output
Mode to mono in the utility menu.

7. Headphone Output -

This jack delivers a speaker compensated, stereo signal. Connect stereo headphones to this jack. Do not connect
a mono jack here as doing so may damage the output driver.

a sequencer, MIDI controller, or MIDI storage device.

10. MIDI Out/Thru -

This jack is used for all MIDI data being sent out of the RP21D. Connect from this jack to the MIDI input of any
external MIDI devices that you wish to control. The MIDI Thru function of this jack simply sends out the same
information that is received at the MIDI In of the RP21D.

11. S/PDIF Output -

This is the digital output from the RP21D. The signal at this output is in a digital format, and is to be connected to a
digital S/PDIF input such as those found on digital recorders.

Getting Started

Making Connections

Before connecting the RP21D, make sure that the power to your amplifier is turned off, and that the power to the RP21D is disconnected.
There is no power switch on the RP21D. To turn the RP21D on, simply plug the power supply in to an AC outlet. To turn the RP21D off,
unplug the power supply from the AC outlet.

There are several different amplification options available when using the RP21D. You may run mono into an amp or power amp, stereo into
two amps or a stereo power amp, direct into a mixing console, or a combination of amp(s) and mixing console. The following diagrams
show the connections for some of these options.

Mono

Connect your guitar to the input of the RP21D. Connect the Left Mono output of the RP21D to the instrument input on your amplifier, or to
the line input of a power amp. Set the Output Mode to mono in the utility menu.
