7-Series DC Power Supply Overview
The 7-Series recorders are powered by either a removable Li-ion battery or external DC sources. Sound Devices includes a DC power supply with the unit. The specific supply and its output power varies, based on the time of purchase.
All 7-Series recorders are currently packaged with a DC power supply providing 45 Watts. This supply includes a U.S. IEC power cord, though the supply accepts AC input between 100 V and 240 V, 50/60 Hz. This supply has the model number XL-WPH3.
Discontinued Sound Devices Power Supply Products
Sound Devices has made changes to the power supplies included with the two- and four-channel recorders. The original XL-WPH power supply, a two-prong supply providing 24 watts, has been discontinued. The XL-WPH is shown below.
The XL-WPH2 was also discontinued and replaced with the XL-WPH3. The XL-WPH2 provided 30 Watts and included a U.S. IEC power cord, though the supply accepts AC input between 100 V and 240 V, 50/60 Hz. The XL-WPH2 is shown below.
788T Power Supplies
When first introduced, the 788T shipped with the 30 watt XL-WPH2 supply. With the added demands of eight inputs with phantom on each input, the supply was revised to the present supply, the XL-WPH3.
The XL-WPH3 provides 45 watts, which is more than sufficient to power the unit with all inputs active, and charge an attached Li-ion battery.
