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. 2 AUX OUT L/L+R and R Jacks AUX OUT R L/L+R Stereo System 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 leftand 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. 3 MIDI IN, THRU and OUT Connectors MIDI IN OUT THRU DOU-10 Tone Generator 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 connector, 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. q PHONES Jacks (Bottom Panel) Two pairs of standard pair of stereo headphones can be plugged in here 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. 4
