The DR-10X has both manual and automatic gain settings, with a low cut filter and limiter to prevent overloads. The Dual Recording mode captures a copy of the audio at a lower level, so if there is distortion you have a backup safety.
Recording can begin instantly by holding the record side switch while turning the unit on.
For simple-to-use ENG recording that stays out of the way, TASCAM’s DR-10X leads the field.
