11 INPUTS & OUTPUTS
The Avalon includes numerous audio and CV / Gate inputs & outputs.

11.1 AUDIO I/O

The audio I/O consists of 1/4" and 1/8" jacks on the rear panel. The
1/8" audio jacks are differentiated from the 1/8" CV/Gate I/O jacks in
two ways. First, the text labels for the audio I/O on the top and rear
panels of the unit are surrounded by a box. Second, the audio I/O
direction indicators are shown in color (red or blue).
MAIN OUT is a 1/4" mono jack and is the main output.
PHONES is a 1/4" stereo jack and is the headphone output.
SAW & SQR are buffered +/-5V outputs of the saw and square VCO
waveforms.
EXT IN is an external input to the filter. It accepts a wide range of
signal levels as it has an internal preamp stage. When the external
input is used the sub oscillator is bypassed.
VCA OUT is the output from the VCA before the mixer stage and the
main out. This output can be used to feed the signal back to the filter
input or to external hardware, or to simply bypass the internal mixer
stage to improve performance by reducing noise and distortion.
11.2 CV & GATE I/O
The numerous CV & Gate 1/8" jacks are used for interfacing the
Avalon with external hardware.
CV & GATE INPUTS The GATE IN 1/8" jack allows other analog
devices to trigger the Avalon's envelopes. The CV IN 1/8" jack allows
control of the pitch of the Avalon oscillators from an external source.
When a CV input is plugged into the jack the internal sequencer pitch
CV is bypassed.
GATE IN is a positive 0-5V gate.
CV IN is 1V/octave with a 0-5.333V range.
2V = C2 (65.4Hz)
CV & GATE OUTPUTS are used for sending the Avalon's
sequencer/keyboard CV & GATE to external analog gear.
GATE OUT is a positive 0-12V gate.
CV OUT is 1V/octave with a 0- 5V range.
FILT CV is an input to the filter frequency control input and is used for
modulating the Avalon filter(s) from external gear.
FILT CV is 1V/octave.
The Avalon Filter CV input is non-standard due the nature of the TB-
303 compatibility. The resting voltage of the filter control input is 3.28V.
See Appendix B for details.
SWEEP is short for accent sweep out and is a control voltage output
that gives a normalized and amplified copy of the accent sweep
signal. This is the short burst (wow) envelope that is derived from the
filter envelope on accented notes. This signal is 0-5V max.
