DOU-10

Connections

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.

The AUX OUT L/L+R and 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-154S and CLP-155 feature high-performance stereo amplifiers delivering 20 and

30 watts per channel, respectively. The CLP-155 features a bass-reflex type enclosure with

two 13-cm and two 5-cm speakers, while the CLP-154S houses a pair of 13-cm speaker

units in a sealed enclosure.

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 device (such

as the DOU-10 Disk Orchestra Unit) which can be used to control the Clavinova.

The MIDI THRU connector re-transmits any data received at the MIDI IN connec-

tor, allowing “chaining” of several MIDI instruments 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 15.

•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.
