Lightweight, and pedalboard-friendly, the MXR M238 Iso-Brick Power Supply offers ten fully-isolated outputs ranging from 9V to 18V - with two variable 6V - 15V outputs, and exclusive noise-reduction circuitry for silent performance. Features 10 fully-isolated outputs Quiet, noise-free DC power supply Two outputs with variable voltage (6V - 15V) Two 18V outputs Six 9V outputs Robust and reliable construction Power On/Off and Connection Status LED indicators Each of the Iso-Brick's outputs are fully isolated, effectively eliminating ground loop noise and hum - no matter if you prefer analog or digital, positive or negative ground, this power supply covers all your bases. To accommodate a range of voltage and current output options, the MXR team broke down the 10 outputs to provide two 9V outputs at 100mA, two 9V outputs at 300mA, two 9V outputs at 450mA, two 18V outputs at 250mA, and two outputs with convenient variable voltage from 6V to 15V at 250mA. Using the two variable voltage outputs, you're able to emulate the voltage sag of a drained battery - a unique effect sought by so many tone aficionados. With an incredible design that extends beyond the high-powered, innovative circuitry, the MXR Iso-Brick Power Supply features a robust, small, and lightweight chassis that is built to withstand the most rigorous gigging and touring environments. Included power on/off and connection status LEDs provide a visual indication of the status of your system, and making short work of fault-finding when your signal is interrupted. Strap this little box to your board, and experience silent and reliable power for all your pedals, night-after-night.
