Bastl DUDE User Manual

POWER
0
DUDE is powered by 4xAA batteries or by external
power supply 9–12VDC - center positive polarity -
2.1mm barrel. Inserting a power jack disconnects the
batteries and powers Dude from the external supply.
1
Press the JUICE switch button to turn DUDE ON
or OFF. To check whether the device is powered press
some of the MUTE button switches to check if their light
comes ON. If not check the polarity of the batteries /
power supply.
MIXING
2
There are 5 mono input channels on DUDE. Each
channel has an input jack atthe front. Mono or stereo
signal/cables can be inserted, but DUDE will only listen
to the left channel.
3
The signal of each channel goes thru the MUTE
switch button. When light atthe channel is ON it
means the signal is passing and the channel is active.
note
The MUTE switch buttons are purely
mechanical which means that switching signals with
low harmonic content (sinewaves) might produce
audible clicks.
4
The gain knob for each channel sets amount of
amplification (center and CW) or attenuation (center
and CCW). Maximum gain per channel is +20dB / 10x
gain.
5
The signal from all channels is fed to the active
summing stage and mono to stereo splitter with
separate output buffers for Left and Right channels.
This allows the output jack to be used with headphones
and mono or stereo cables without any problem.
Both inputs and outputs are AC coupled.

Summary

DUDE Power Specifications

Power Source and Connection

Powered by 4xAA batteries or external 9-12VDC supply. External power disconnects batteries.

Turning DUDE On/Off

Use the JUICE switch. Check power status via MUTE button lights; verify polarity if not lit.

DUDE Mixing and Signal Flow

Input Channels and Muting

5 mono input channels accept mono/stereo (left channel only). MUTE buttons control signal passage.

Gain Control and Summing

Gain knobs adjust amplification (+20dB max). Signals sum to a mono-to-stereo splitter.

Output Stage

Separate buffers for Left/Right outputs. Suitable for headphones and stereo/mono cables.

DUDE Features Overview

Channel Configuration

5-channel monophonic mixer with individual mute buttons and up to +20dB gain per channel.

Output Capabilities

Dual mono output designed for driving headphones.

Power Options

Flexible power via 4x AA batteries or a 9-12VDC external adaptor.

Advanced DUDE Applications

DUDE as Feedback Processor

Use gain to saturate signals, creating unique saturated sounds or wave-shaping.

DUDE in Modular Setups

Combine DUDEs with passive splitters for diverse mixing scenarios, like effect send chains.

DUDE as Tone Generator

Non-inverting mixer output can feed back to inputs for oscillating tones; EQ modifies pitch.

Battery and Headroom Notes

Battery Types and Headroom

Alkaline batteries offer more headroom (+/-2.7V) than rechargeables (+/-2.1V).

External Power vs. Battery

External adaptor provides regulated 6V, matching alkaline battery headroom.

Signal Levels and Clipping

Headroom is signal clipping threshold. Modular synth levels (+/-5V) may require gain reduction.
