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
| Configuration | Idle | While Recording |
| baseline (no mics, battery, or XLDVDRAM) | 7.2 W | - |
| battery attached and charging | 15.6 W | - |
| no battery, 2 mics with phantom power (48V) |
7.5 W | 12 W |
| battery charging, 2 mics with phantom power (48V) |
18 W | 23 W |
| no battery, 2 mics with phantom power (48 V), XL-DVDRAM attached |
14.5 W | 19.2 W |
| battery charging, 2 mics with phantom power (48 V), XL-DVDRAM attached |
23 W | 29 W |
Recording to Compact Flash Only
| Configuration | Idle | While Recording |
| baseline (no mics, battery, or XLDVDRAM) | 7.2 W | - |
| battery attached and charging | 15.6 W | - |
| no battery, 2 mics with phantom power (48V) |
7.5 W | 12 W |
| battery charging, 2 mics with phantom power (48V) |
18 W | 18 W |
| no battery, 2 mics with phantom power (48 V), XL-DVDRAM attached |
14.5 W | 18 W |
| battery charging, 2 mics with phantom power (48 V), XL-DVDRAM attached |
23 W | 26.5 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.
