The 788T introduces a new microphone preamp and analog-to-digital topology to Sound Devices. This new circuit improves the dynamic range of the microphone inputs beyond the performance of the class-leading 702, 702T, 722 and 744T recorders.
The 702T, 744T, and 788T include powerful time code functionality. One time code feature is the ability for the recorder's time code clock to chase an external time code source. This is called "reader" mode. The time code value displayed by the recorder will indicate a +1 frame offset from the external master time code source when the master is in stop mode. This is normal behavior.
Since the conception of the 788T, Sound Devices engineering designed the recorder to make sure that it could be used in a bag in close proximity to wireless receivers without ill effect. The result: the 788T is a benchmark for digital recorders and RF performance.
7-Series recorders automatically switch from external DC power to the attached Li-ion battery when the external voltage falls below a 9 volt threshold (or the setup-menu set voltage on the 788T). This seamless switchover provides protection against sudden or unexpected loss of external power.
