INPUT/OUTPUT PANEL

The back panel provides all of the input and output connections. In addition
to AUDIO INPUT/OUTPUT jacks, there are CV and GATE inputs, connections for
MIDI, and the Power Connector. The Minitaur does not have a power switch.

12VDC (POWER INPUT)

A  barrel connector that accepts a +12VDC, tip positive power input from
the power adaptor, which accepts 100-240 VAC, 50-60Hz.

CONTROLLER INPUTS

The PITCH, FILTER and VOLUME CV jacks supply power and will accept an
expression pedal such as the Moog EP-2, or a Control Voltage from 0 to
+5 Volts. The GATE input accepts a +5 Volt trigger signal.

MIDI (DIN AND USB)

Connections for DIN MIDI input and USB MIDI IN-OUT.

AUDIO IN

The AUDIO IN jack allows an external audio source to be mixed with the 
Minitaur’s VCOs, and then routed to the Filter for processing. Although
the Minitaur has no provisions for adjusting the level of this input on
the front panel, the level is adjustable up to 200% via MIDI CC# 27.

AUDIO OUT

The AUDIO OUT jack provides an unbalanced line-level signal for conne-
cting to an amplifier or mixer.

HEADPHONE OUTPUT

1/8” minijack for stereo Headphone Output. 32

Ω  

or higher recommended 

impedance.

18

BACK PANEL

The Minitaur features a monophonic Audio Output and a Headphone
Output; both outputs appear on the back panel. Both ouputs are
adjusted simultaneously by the VOLUME control.
 

VOLUME (VCA)

PANEL CONTROL FOR VOLUME 

VOLUME:

Adjusts the output of the Voltage Controlled Amplifier (VCA) and Head-
phone levels. Rotating the control fully clockwise produces the maximum
output. Rotating the control fully counterclockwise silences the Minitaur.
The VOLUME control does not transmit or receive MIDI. This is a post VCA
control.

MIDI ACCESSIBLE CONTROL

OUTPUT LEVEL 

(CC# 7):

Adjusts the Audio Output and Headphone volume levels.

VOLUME VELOCITY SENSITIVITY 

(CC# 90):

Velocity scales the amplitude of the Amplifier envelope Similar to tradit-
ional touch sensitivity.
Default = 64 (50%).

EXTERNAL CONTROL

The VOL CV jack on the back panel is an input for external control of the 
Output level. A voltage of 0 Volts silences the Minitaur and a voltage of
5 Volts corresponds to the output level set by the VOLUME control knob.
The jack accepts a positive Control Voltage from 0 to 5 Volts, or an expre-
ssion pedal like the Moog EP-2.
