For podcasts, sound effects, and music recording applications, the TASCAM DR-40X portable handheld recorder is capable of capturing up to four tracks of high-resolution audio with no external microphones required. Its onboard unidirectional condenser mics can be set for a wide or tight stereo image, and may be used simultaneously with the mic/line combo inputs. Equally adept as a handheld device or when used in stand- or camera-mounted setups, the DR-40X can handle anything from sampling sessions and interviews to podcasts and live concerts.

Flexible powering methods—batteries, USB bus power, or an AC adapter—make the DR-40X well suited to on-the-go recording, all-day video shoots, and computer-based audio production. Need to patch in external mics or an outboard mixer? The DR-40X's two balanced XLR-1/4" inputs accommodate mic- or line-level signals (even +4 dBu from professional consoles) and can supply phantom power if needed. Whether you use the built-in mics or an external source, selectable modes such as stereo safety track recording, peak reduction, limiting, and auto level give you options for achieving a clean, undistorted recording.

Adjustable Unidirectional Microphones The DR-40X's onboard condenser microphones empower you with stereo capture or 2 x stereo capture when used with the mic/line inputs. For sources producing sound pressure levels up to 125 dB, loud concerts won't be a problem. Whereas the DR-05X has omnidirectional mics in a fixed A-B setup, the DR-40X features adjustable unidirectional mics. The unidirectional mics minimize the pickup of sound entering from the rear of the capsules, resulting in a more focused tone with fewer reflections.

Easily pivot the capsules between two mic configurations to complement your sound source—use the A-B position (capsules facing outward) to produce a wide stereo image, or switch to the X-Y position (capsules facing inward) if you need a tighter stereo field with a strong center presence and fewer phase differences.
Dual XLR-1/4" Mic/Line Inputs with Phantom Power Dual Neutrik XLR-1/4" TRS combo jacks support mic level and +4 dBu line level, allowing you to record external microphones or balanced outputs from a mixer or FOH console. With switchable 24V or 48V phantom power and ample gain, the mic preamps can serve a variety of microphones such as dynamic, ribbon, or condenser types. Using the onboard microphones, you can capture the ambient sound of an audience while recording direct from an external console, which is ideal for live performances.
