Setting Up Your System
The QR10 provides plenty of musical potential by itself, without extra equipment and complicated connections. It can,
however, be used with other equipment in a variety ways to meet a wide range of individual needs. A few examples are
provided below to help you get started.
■ The Connectors
1PHONES Jack
Any pair of stereo headphones with a miniature stereo phone plug can be plugged in here for convenient monitoring.
The PHONES output level is adjusted via the VOLUME control on the right side panel.
DETAIL
The built-in speaker is automatically shut off when a pair of headphones is plugged into the PHONES jack.
2OUTPUT Jack
This miniature stereo phone plug delivers a line-level stereo output signal from the QR10 for connection to a stereo sound
system (see “Audio Connections,” below). The output level is adjusted via the VOLUME control on the right side panel.
3INPUT Jack
This 1/4" monaural phone jack accepts input from an electric guitar or bass, an electronic keyboard, a microphone (high-
impedance types), or other audio source. The signal received at the INPUT jack is mixed with the QR10’s own sound and
delivered via the built-in speaker system, the OUTPUT jack (above), or the PHONES jack (also above) as required.
The INPUT GAIN function described on page 5 should be used to match the input gain of the QR10 to the connected instru-
ment or source.
DETAIL
The INPUT jack can also be used as a footswitch jack for playback start/stop and chord change operation when the
FOOTSWITCH function is turned ON (> page 11).
4MIDI IN & OUT Connectors
If you plan to use a MIDI keyboard or other instrument to play and program the QR10, it should be connected to QR10
MIDI IN connector. The MIDI OUT connector can be connected to an external MIDI data recorder such as the Yamaha MDF2
if you want to store your songs and patterns to floppy disk (> page 43).
5DC IN Jack
This jack is only used when you are powering the QR10 from an optional AC adaptor instead of batteries. The DC output
cable from an optional Yamaha PA-3 AC Power Adaptor is plugged in here.
DETAIL
The batteries are automatically disconnected when a plug is inserted into the DC IN jack.
