****** Page 1 ****** electro-barmonix Organ Machine Congratulations on your purchase of the Electro-Harmonix C9 Organ Machine. The C9 transforms the tone of a guitar or keyboard into that of a convincing electric organ yet is easy to use and play. Based on the sound engine found in the EHX B9 Organ Machine, the C9 delves deeper into the sonic territory of classic organs covering a vast array of memorable electric organ tones. The C9 has controls covering percussive attack level, modulation speed, and both organ and dry volume. WARNING: Your C9 comes equipped with an Electro-Harmonix 9.6DC-200BI power supply (same as used by Boss@ & Ibanez@: 9.6 Volts DC 200mA). The C9 requires 100mA at 9VDC with a center negative plug. Using the wrong adapter or a plug with the wrong polarity may damage your C9 and void the warranty. GETTING STARTED Connect the supplied power adapter to the 9V power jack. Plug your instrument into the INPUT jack; connect your amp to the ORGAN OUTPUT jack. Set the DRY knob to minimum and all the other top row knobs to about mid position. Select the preset named TONE WHEEL and step on the footswitch to turn on the LED. Play your instrument and adjust controls to your liking. MOD controls modulation speed and CLICK controls percussive click level. DRY VOLUME KNOB Controls the volume of the untreated instrument at the ORGAN OUTPUT jack. ORGAN VOLUME KNOB Controls the overall volume of the ORGAN preset. MOD KNOB MOD controls the speed of modulation. Modulation can be completely turned off when MOD is set fully counterclockwise. The type of modulation is contingent on the preset selected. The different types of modulation available are vibrato, tremolo and chorus. See the preset descriptions for modulation type. CLICK KNOB CLICK controls percussive click level. It was designed to simulate the harmonic percussion effect on classic B3 and C3 organs. The click is added to the very first note or chord played. The click will retrigger only when current notes have been released and their amplitude falls below a threshold. For most presets, CLICK controls parameters unique to the preset. See the preset descriptions for details.

DRY OUTPUT JACK DRY outputs the signal present at the INPUT Jack through a buffer circuit. The dry signal is outputted regardless if the C9 is in Effect or Bypass mode. The DRY Volume knob does not change the volume at the DRY Output jack. ORGAN OUTPUT JACK ORGAN outputs the mix set by the DRY and ORGAN controls. PRESET DESCRIPTIONS 1. 2. 3. 4. 5. 6. 7. 8. 9.
