Tascam DA-45HR DAT recorder

Here's the new standard in audio mastering technology. The Tascam DA-45HR is the worlds first 24-bit high resolution DAT recorder. It combines stunning audio performance with a rugged transport, advanced features and backward compatibility with standard 16-bit DAT.

A full audio I/O complement and word sync in/thru provide all the tools to integrate into any analog or digital studio of any size. Perfect for studios and mastering houses, the DA-45HR bridges the gap between the 16 bit and 24 bit worlds with a familiar interface you already know.

 

The 24 bit format DAT uses the same DAT tape that is used in standard DAT recorders. In order to store the extra data generated by higher resolution recording, the tape speed is doubled in HR (High Resolution) mode. So, when you're recording in 24 bit HR mode, a standard 120 minute tape will last 60 minutes. Obviously, 24 bit DAT tapes will only play back on a 24 bit DAT recorder like the DA-45HR.

The DA-45HR can also run just like a standard 16 bit DAT recorder, running normal speed and writing 16 bits to the tape. Reading and writing is fully supported, so you won't have to dig out a different DAT recorder for anything else.

Denon DTR-2000

 DTR-2000 is one of the first DAT (Digital Audio Tape)Recorder  created for consumer users . By incorporating the SCMS (Serial Copy Management System), it enables users to make as many direct, first-generation digital dubs of CD's and other digital program sources as they wish, while limiting the ability to make digital copies of copies.

It also features an advanced version of Denon's 20-bit Super-Linear D/A (digital-to-analog) converter, called the lambda SLC.  The DTR-2000 comes with full-function remote control and complements ita analog connectors with both optical and coaxial digital inputs and outputs. While a number of manufactures have adopted one form or another of 1-bit D/A conversion. Denon has chosen instead to remain with the eight-times-oversampling, 20-bit Lambda SLC system, originally developed for its top CD players. 

 The Lambda enhancement is designed to minimize the zero-crossing distortion that is characteristic of most multibit D/A converters. Non-linearity is reduced still further by very careful factory adjustment of the converter's  MSB (most-significant-bit) registers. At the other end of the process, ahigh-speed analog-to-digital converter is used to quantize analog input signals.

The transport mechanism inside the deck is similar to that of a miniature VCR and uses the same helical-scan principle. The high tape-to-head speed needed for mutimegahertz frequency response, is achieved with a pair of heads mounted in a rapidly rotating drum set at an angle to the longitudinal direction of the tape.

Optical and coaxial digital input and outputs as well as analog inputs and outputs

Sigma/Delta A/D converters

Lambda SLC 20-bit D/A converters with eight-times oversampling
