NAE 2011: Introducing the Powertrain 1250
The folks at Pedaltrain had a brand new pedal power supply on offer at the Nashville Amp Expo this weekend – the Powertrain 1250. The box, designed by Creation Audio Labs, is a low noise DC pedal power system with five isolated sections to help break up potential ground loops and lower the noise floor. Two isolated sections may be connected in series for higher combined voltages, or in parallel for high combined currents. All outlets are tip negative 5.5 X 2.1mm output.
The first isolated section is switchable for 9v, 12v, 15v or 18v DC and provides up to 150mA. The next three isolated outputs are set to 9v DC, provide up to 210mA each and have a load dependent voltage control that has the effect of ‘starving’ some pedals like a weak battery, which can have desirable effects on headroom, distortion, sustain and break-up of certain pedals.
The last section consists of four paralleled outputs set to 9v DC, which provide a total of 500mA. These can be used to power pedals that don’t mind sharing power with other pedals. These outputs can also be used with daisy chain cables to allow the Powertrain 1250 to run even more pedals.
The initial batch of Powertrain 1250s were being sold at the show for $200.
