Tascam DA-6400 is "Best Of ISE 2018“

10.04.18 - 

The Tascam DA-6400 Multitrack Digital Recorder was honoured with the “Best Of ISE 2018” award by rAVe Publications as the best new audio product.

The DA-6400 is a universal recording system for up to 64 audio tracks received from a Digital Audio Workstation or live mixing console. The recorder can be used with a variety of interface boards like MADI, Dante, DigiLink, AVB or AES/EBU to integrate flawlessly into virtually any environment. Moreover, Tascam plans to maintain the recorder as a living system by adapting it continuously to new interfaces and systems according to the needs of users.

The DA-6400 uses a special real-time operating system and highly reliable SSD drives for storage. A model with rundant power supply is also available (DA-6400dp).

High stability and high reliability in both recording and playback

Embedded operating system for high stability and simple standalone operation

The DA-6400 uses an embedded operating system for quick startup and simple operation. Stable recording is possible when using high sampling rates with large amounts of data transmission. Furthermore, files are saved approximately every 20 seconds during recording, so file losses due to unexpected power supply interruptions are kept to a minimum.

Supports recording/playback of 64 channels at 48 kHz or 32 channels at 96 kHz

PCM recording/playback from 48 kHz to 96 kHz maximum is supported for compatibility with existing recording studio systems, PA systems and other recording situations where high sampling rates are being utilized.

Note: 32 channels are supported at 96 kHz/24-bit resolution.  

Solid-state drives (SSD) as recording media

The DA-6400 uses solid-state drives (SSD), which have excellent vibration and environmental resistance and offer simple, maintenance-free operation. It includes a Tascam SSD designed and thoroughly tested using DA-6400 units.  Component parts, including IC control elements, are carefully selected and constantly tested lot by lot in cooperation with the parts manufacturers to maintain quality specifications.

By installing SSDs into removable AK-CC25 storage cases and using the swappable bay in the DA-6400 unit, it is easy to switch and use multiple drives. Since the DA-6400 is hot-swappable, it is possible to remove and load SSDs stored in AK-CC25 cases even when the power is on, making rapid switching of media possible. SSDs stored in AK-CC25 cases can be connected to computers by USB and used as external drives.

Note: One AK-CC25 and one TASCAM SSD are included with each DA-6400/DA-6400dp unit. Additional cases and drives can also be purchased separately.

Stable digital signal control with 1 ppm accuracy

Because the clock generator can influence digital signal quality, the DA-6400 employs a temperature-compensated crystal oscillator (TCXO) that boasts a high precision of ±1 ppm (0.048 Hz at 48 kHz).

Additional model featuring a redundant power supply

In addition to the DA-6400 standard model, the lineup also includes the DA-6400dp which has two power supply circuits built-in to allow redundant power from another AC circuit. This provides failsafe operation in case AC power is interrupted on one of the circuits.

1U size enables installation where rack space is at a premium

A single DA-6400 can record and play back up to 64 channels but requires only a small amount of space for installation due to its compact 1U design.
