Output Connect to guitar amplifier, mixer, or audio amplifier. If you use an effects unit like an echo chamber, connect it between the output jack and the amplifier. When using audio amplifiers such as those in home stereo systems, use caution with the volume control because the synthesizer is capable of generating sound levels high enough to destroy the speakers.
Phones Connect headphones to this jack. Use headphones designed for normal home stereo systems. Roland RH-2 headphones are suited for this purpose.	Gate Input In the same way as the CV input, gate pulses from external sources can be connnected to this jack.
CV Output This jack outputs the control voltage from the SH-09 keyboard. Connect to the CV input for an external synthesizer or the MC-8 MicroComposer to control such devices with the SH-09. Gate Output The gate output from the SH-09 keyboard can be taken from this jack. Connect to the gate input of an external synthesizer or the MC-8 MicroComposer for control of such devices with the SH-09 keyboard. CV Input This jack receives control voltage inputs from sources such as the VK-6 or VK-9 organ, the model 104 (System 100) or model 717A (System 700) Analog sequencer, the MC-8 MicroComposer, the RS-09 String synthesizer, etc.	Ext. Audio in Connect external sources such as microphone, electric guitar, electric piaon, or strings to this jack. As the SH-09 incorporates an envelope follower, the VCF can be controlled by the level of the signal from the exteranl source to use the SH-09 as a kind of effects unit like automatic wah. When connecting the strings such as the Roland RS-09, connect the gate output also to make it possible to control the envelope generator of the SH-09 from the strings keyboard. With this arrangement, the VCF can be activated on brass chords producing sounds like a polyphonic synthesizer.
