Audio Connections; Midi Connections - Yamaha QY-8 User Manual

3 DC IN Jack
This jack is only used when you are powering the QY8 from an optional
AC adaptor instead of batteries. The DC output cable from an optional
Yamaha PA-1B or PA-3 AC Power Adaptor is plugged in here.
The batteries are automatically disconnected when a plug is
inserted into the DC IN jack.
DETAIL

Audio Connections

The simplest way to monitor the QY8 sound is via a pair of stereo
headphones (miniature stereo phone plug type) plugged into the
PHONES/LINE OUT jack. If you want to use an external stereo sound
system, however, use the PHONES/LINE OUT jack and a "Y" cable
(miniature stereo phone plug to dual RCA pin plugs — available from
many audio and musical instrument dealers).
Make sure that both the QY8 and your sound
system are turned OFF when making connections.
CAUTION

MIDI Connections

Although the QY8 can be programmed without a keyboard, an external
MIDI keyboard connected to the QY8 MIDI IN connector provides
the added advantages of standard keyboard format and key velocity
sensitivity (if your keyboard has a velocity-sensitive keyboard). Connect
the MIDI OUT connector of the keyboard to the MIDI IN connector
of the QY8, and make sure that your keyboard is set to transmit on the
appropriate MIDI channel. (See pages 43, 66)
