Mini Power
The Mini Power has been designed specifically for 1Frame Setups and runs from an external 18V AC
(not DC!) wall-wart to generate a /-15v bipolar supply (max. current c.300mA per side) which is
then distributed to modules within the frame via an internal power bus board. Features from top to
bottom:
•
On/Off Power Switch
•
Power input for 18V AC external wall-wart (supplied within UK/EU) - 1100mA minimum
required, 2.1mm plug
•
Power indicator LEDs for V+/V-
•
Common Ground connection to integrate with other systems
•
Two 1/4" jack to banana converters – these are connected to the internal System Ground.
Connecting External Signals
You can connect external CV / Gate signals either via the jack-to-banana connectors on the Mini Power
or via custom interface cables. Note that, due to the signal amplitudes within the system, most audio
signals will require considerable amplification to reach suitable levels – this is usually achieved by the
UTL1 Dual Preamp module, though this is not included in this system.
If using interface cables, the first cable should have a ground connection which plugs to the System
Ground point on the Mini Power module. Once this common ground has been established, any further
connections do not require further ground cables.
An external Midi-to-CV converter allows the system to be played as a traditional synthesiser. For
example, the 1V/Oct CV would plug to the V/Oct input on the VCO(s) and the Gate signal would be
patched to the Gate input of the Envelope.
