I accidentally purchased this and have only used it to check its functionality. ----- Features The DC junction box HUB-6 ver.II is used to split the output from a DC9V adapter or power supply. By coupling a digital voltmeter, it is possible to monitor the voltage state and monitor for problems caused by overcurrent and voltage drops, which are likely to occur when DC voltage is split. Specs ■DC Junction Box (DC output 5-way hub) ■Features ・Parallel junction box with 6 x DC jacks that splits the DC output of a power supply or power adapter into 5 systems. ・Equipped with a digital voltmeter, it not only distributes power to effect pedals but also allows for monitoring of voltage status. ・By monitoring voltage drops, it can prevent problems caused by overcurrent, which is likely to occur when splitting the DC voltage of a power supply. ■Input/Output: 6 x DC jacks (parallel connection) center pin 2.1mm ■Size: 101.5 (width) x 34.2 (depth) x 27 (height) mm / 88 g ■Accessories: DC cable x 5 CUSTOM AUDIO JAPAN
