Technical Documentation  
PRODUCT OVERVIEW  
The DTRS format has long been respected as the most  
reliable format in digital recording, and now the DTRS  
format is leading the way into high resolution 24 bit  
recording. The DA-78HR works with 16 bit DTRS  
machines, using the same DTRS Sync line for sample  
accurate lock plus the ability to read and write the  
older 16 bit format. However, the DA-78HR offers the  
ability to write 8 tracks of 24 bit audio to tape in the  
HR format, built in SMPTE synchronization, MIDI ports  
for MTC and MMC, plus a built-in 8 channel digital  
mixer for internal bounces or monitor mix generation.  
• Records 8 tracks of 24 Bit Audio To Hi8 Tapes  
• 24 Bit A/D and D/A Converters  
• Reads and Writes 16 and 24 Bit DTRS Tapes  
• 16 Machine Sample Accurate Lock with DTRS Sync  
• Balanced DB25 & Unbalanced RCA Analog I/O  
• TDIF Digital I/O & SPDIF Digital I/O  
• Word Sync In/Out/Thru  
• >104dB Dynamic Range  
• 108 Minutes of Record Time on 120 Hi8 Tape  
• SMPTE Time Code Generation and Chasing  
• Generates MIDI Time Code  
Track Slip from -200 to +7200 Samples  
• Built-In 8 Channel Digital Mixer  
• Responds to MIDI Machine Control

Maximum features, minimum hassle. The DA-78HR brings  
DTRS tape into 24 bit audio, offering the very best sound  
quality available today. New features like built in MIDI ports  
and SMPTE synchronization gives you the ability to chase other  
tape machines (analog or digital), and the ability to work with  
sequencers and digital consoles. For the ultimate cost effective  
flexibility without having to locate additional accessories, the  
DA-78HR is the best digital tape machine for the market.

Live Performance and Recording  
In live performance, there is no take 2. Whether you are  
using the DA-78HR to play some additional backing tracks or  
recording the performance live, you can count on the DA-78HR  
to get it right the first time. With 108 minutes of record time  
on a single tape, you can put a whole live song set on a single  
tape; no need to stop everything so you can switch tapes.

Digital I/O:  
For anyone trying to make music for television or film, the  
DTRS format is the de-facto standard format for transfers  
and many stages of recording. The synchronization features  
will allow you to chase another audio machine, or a video deck.  
Again, the 108 minute record time was maintained for the new  
24 bit recording mode, allowing 1 hour reels to be stored on a  
tape, along with reference tones and the independent subcode  
time code track. More advanced video applications will want  
a DA-98HR, which adds 9 pin control, blackburst resolve, and  
built in bit split for higher resolution audio recording.
