1 we strongly recommend using a tascam ps-p520u or the usb power adapter included with the ipad/iphone. no usb power adapter is included with an ipod touch. to use it with an ipod touch, purchase a genuine apple usb power adapter (that can supply 5 v and a current of at least 700 ma) separately.
2 we strongly recommend using a tascam bp-6aa external battery pack. if using another external battery pack or mobile battery, purchase one that can supply 5 v and a current of at least 700 ma.
