Tascam DR-40X Four-Track Handheld Recorder
The Tascam DR-40X is a four-track handheld recorder with built-in stereo condenser mics and two XLR/TRS inputs that take mics or +4 dBu line sources.
The built-in cardioid mics adjust between X-Y and A-B positions and accept high sound pressure levels. The XLR/TRS combo inputs supply 48 V phantom power for condenser mics.
Recording
In four-track mode, the DR-40X records the built-in mics and the external inputs as two stereo files at once, or one source as two stereo files at different levels for a safety copy. It writes WAV/BWF files at up to 96 kHz and 24-bit, or MP3 at 32 to 320 kbps, to SD cards up to 128 GB.
A mixdown with level, pan, and effect controls for each track turns a four-track recording into a stereo track. Non-destructive overdubbing records a new stereo file while earlier ones play back, an overwrite function punches in with one level of undo, and an MS decoder works with mid-side mics.
Levels are set by hand or automatically, with peak reduction, auto level, and limiter options, plus a low-cut filter at 40, 80, 120, or 220 Hz. Recording can start and stop by input level, and a two-second pre-record buffer, a self-timer, and an auto tone for syncing with a camera are built in.
USB, Power, and Playback
The DR-40X also works as a 2-in/2-out USB audio interface with Mac and Windows computers. It runs on three AA batteries, USB bus power, or an optional Tascam AC adapter, and takes the optional Tascam RC-3F footswitch and RC-10 wired remote.
On playback, variable speed audition runs from 50 to 200 percent. A built-in speaker, a reverb effect, and a chromatic tuner are on board.
