Connections
These jacks are intended for use with an external tone generator module such as
the Yamaha DOM-30 Disk Orchestra Module. The stereo outputs from the exter-
nal tone generator module are connected to the OPTIONAL IN L and R jacks,
allowing the sound of the tone generator to be reproduced via the Clavinova’s
internal sound system and speakers.
The AUX OUT R and L/L+R jacks deliver the output of the Clavinova for con-
nection to an instrument amplifier, mixing console, PA system, or recording equip-
ment. If you will be connecting the Clavinova to a monaural sound system, use
only the L/L+R jack. When a plug is inserted into the L/L+R jack only, the left-
and right-channel signals are combined and delivered via the L/L+R jack so you
don’t lose any of the Clavinova’s sound.
The Internal Amplifier & Speaker System
The CLP-122S features a high-performance stereo amplifiers delivering 15 watts per
channel to a pair of 16-cm speaker units.
Note: The AUX OUT jack signal must never be returned to the OPTIONAL IN jacks, either
directly or through external equipment.
The MIDI IN connector receives MIDI data from an external MIDI device (such
as the DRC-20 Disk Recorder, or DOM-30 Disk Orchestra Module) which can be
used to control the Clavinova. The MIDI THRU connector re-transmits any data
received at the MIDI IN connector, allowing “chaining” of several MIDI instru-
ments or other devices. The MIDI OUT connector transmits MIDI data generated
by the Clavinova (e.g. note and velocity data produced by playing the Clavinova
keyboard).
More details on MIDI are given in “MIDI FUNCTIONS” on page 14.

Two pairs of standard pair of stereo headphones can be plugged in here for pri-

shut off when a pair of headphones is plugged into either of the HEADPHONES
jacks.
