Powering Sound Devices Products from AC
Most Sound Devices mixers, amplifiers, and recorders have external DC inputs. These inputs can be used with AC transformers (and switching power supplies) to provide power for their operation. The 302, 442, HX-3, MixPre, and MM-1 can be powered from external DC sources with voltages ranging from 5 to 18 volts. The 702, 702T, 722, and 744T can run on external voltages from 10 to 18 VDC.

Battery Life of the 7-Series Recorders
Q: What is the battery life of these recorders?
A: Run time estimates vary significantly depending on two primary factors, 1) power available and, 2) current draw. The OE (factory supplied) battery is a 4600 mAH capacity (722 and 744T) cell which under typical situations will power the unit for approximately 2 hours. Batteries in large capacities (+7000 mAh) are usable with the 7-Series. (more…)
