Shift Line A+ Astronaut Manual

A+ Astronaut Modular is a eurorack version of the Astronaut III space
reverb. Astronaut III has gained a worldwide following as a
multifunctional reverb pedal for guitar and bass. Now, it has been
adapted to eurorack modular systems: we have reworked the form
factor, retained all the original features, and added CV control over
certain parameters. The whole sonic palette of the Astronaut III (ranging
from traditional reverb patches to complex acoustic structures and
arpeggios) is available in the Astronaut Modular. The module has 22
algorithms along with the Hold (infinite sustain) mode. The Astronaut
Modular is a true inspiration machine!

Controls
1. The VOLUME knob controls the MIX OUT volume (with an option to
boost the signal).
2. The MIX knob controls the ratio between the wet and dry signals at
MIX OUT.
3. The PROGRAM knob selects algorithms within a bank.
4. The BANK button switches between the two banks.
5. The DECAY knob controls the size and spatial/acoustic parameters of
the selected algorithm. It controls reverb decay length as well as
feedback in certain algorithms (read more in the "List of Algorithms"
section).
6. The CHARACTER knob controls an extra parameter of the selected
algorithm (read more in the "List of Algorithms" section).
7. The HOLD button activates Hold Mode (infinite sustain) when pressed
and held.
Connections
• IN is a mono input for the incoming signal.
• MIX OUT is a mono output for the dry/wet mix (the ratio is controlled
by the MIX knob).
• WET OUT is a mono output for the wet signal only.
• CHARACTER CV is an input for CV control over the CHARACTER knob
(10Vptp).
• HOLD CV is an input for CV control over the HOLD button. The effect
is the same as holding the button. The input is set to a +2V threshold.
• DECAY CV is an input for CV control over the DECAY knob (10Vptp).
In case of CV control, the DECAY and CHARACTER knobs set the middle
point of their respective parameters and the control voltage shifts that
point within a ±5V range. When the DECAY and/or CHARACTER knob is
set fully counterclockwise, CV will only increase the setting; if the knob
is set fully clockwise, CV will only decrease the setting.
The WET and MIX outs can be used simultaneously.
LED Indication
Upon startup, the LEDs indicate the selected bank:
• LEDs glow white: Bank 1 is selected.
• LEDs glow blue: Bank 2 is selected.
When Hold Mode is active, the LEDs flash and spin in a circle.
