1、With 8 completely isolated high-current DC 9V (each max.500mA) outputs, providing stable and noise free performance; can power 8pcs DC 9V guitar effects at the same time without losing any signal intensity. 2、Comes with 8pcs DC cables for connecting your pedals, and 1pc Y cable(boost the voltage to 18V), can power 9V and 18V guitar effects at same time. 3、8 Isolated short circuit and over current conservation can ensure the stable working condition; supports self-conservation mode, and it will auto-restart in about 2s once you unplug the short-circuited pedal. 4、FCLC(foldback current limiting circuit) provides ultimate conservation against power shortages and overloads. Even at full load, you will enjoy the quiet and cool operation of a fully regulated power supply. 5、Each output with LED light to indicate the using mode, and it also indicate the fault pedals when the LEDs turn on RED; compact size design with full metal shell, lightweight, portable and durable.
