Power Consumption of 7-Series Recorders

Power consumption varies when using a 7-Series Recorder. The chart below shows the power consumption of a 744T recorder in several configurations.

Recording To Internal Hard Drive Only

ConfigurationIdleWhile Recording
baseline (no mics, battery, or XLDVDRAM)7.2 W-
battery attached and charging15.6 W-
no battery, 2 mics with phantom power (48V)7.5 W12 W

Note: The 744T was powered by an external 12 VDC supply, LEDs set for medium brightness, and no backlight.

Use the chart above as a starting point to calculate power consumption. Power draw varies depending on source voltage, the type of microphones used, and the charge state of the battery.
