for private practice or late-night playing. The internal speaker system is
automatically shut off when a pair of headphones is plugged into either of
the PHONES jacks.

2 AUX OUT L/L+R and R Jacks
Stereo System
These jacks are intended for use with an external tone generator module
such as the Yamaha DOU-10 Disk Orchestra Unit. The stereo outputs from
the external tone generator module are connected to the AUX IN L and R
jacks, allowing the sound of the tone generator to be reproduced via the
Clavinova’s internal sound system and speakers.
NOTE
•The input signal from the AUX IN jacks is delivered to the AUX OUT
jacks, but is not affected by the Clavinova’s volume control or reverb
effect.
The AUX OUT L/L+R and R jacks deliver the output of the Clavinova
for connection to an instrument amplifier, mixing console, PA system, or
recording equipment. 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 deliv-
ered via the L/L+R jack so you don’t lose any of the Clavinova’s sound.
The Internal Amplifier & Speaker System
The CLP-157 features a powerful stereo amplifier delivering 50 watts per channel,
driving a speaker system that puts out exceptionally rich sound with natural re-
sponse from powerful lows to shimmering highs. The speaker system includes two
18-centimeter, two 5-centimeter, and two 5 x 9-centimeter oval speaker units.
NOTE
•The AUX OUT jack signal must never be returned to the AUX IN jacks,
either directly or through external equipment.
The MIDI IN connector receives MIDI data from an external MIDI de-
vice (such as the DOU-10 Disk Orchestra Unit) which can be used to con-
trol the Clavinova. The MIDI THRU connector re-transmits any data re-
ceived at the MIDI IN connector, allowing “chaining” of several MIDI in-
struments 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 18.
