Troubleshooting
Power won’t turn on.
− Is the AC power cord connected correctly?
No sound.
− Try setting the panel controls to the settings described in the “Basic settings” on
page 22.
− Could the LEFT SPEAKER slider, RIGHT SPEAKER slider (see “Front panel
(SPEAKER section L, SPEAKER section R)” on page 16), the VCA section’s
VCA AUDIO input level 1 slider (see “VCA (Voltage Controlled Amplifier)” on
page 12), the MIXER section’s input level 1 slider, or the input level 2 slider (see
“MIXER” on page 13) be lowered all the way?
− Is the ARP 2600 FS correctly connected to the input jack of your amp, mixer, or
headphones?
− Is your amp or mixer powered-on, and is the volume raided on that device?
− Could the ARPEGGIATOR selector be set to PLAY?
Immediately after the power is turned on and an arpeggio pattern has not yet
been recorded, playing the keyboard will not produce sound (see “Arpeggiator
settings” on page 23).
Does not respond to MIDI data sent from an external device.
− Is the MIDI cable or USB cable connected correctly? (see “Connections” on
page 20)
− Does the MIDI channel of the data being sent from the external MIDI device
match the global MIDI channel of the ARP 2600 FS? (see “MIDI channel” on
page 24)
Can’t input sound from an external audio source.
− Is an external audio source correctly connected to the input jack of
the PREAMPLIFIER section? Also, could the GAIN knob be at 0? (see
“PREAMPLIFIER” on page 6)
− Is the output jack of the PREAMPLIFIER section connected to the audio input of
the VCF or MIXER?
