Overview
The first device to use the format was the DA-88. This modular, digital multitrack device uses tape as the recording medium and could record up to eight tracks simultaneously. It also allowed multiple DA-88 devices to be combined to record 16 or more tracks.[3] The first models in the series (the TASCAM DA-88, DA-38, DA-98 and Sony PCM-800) recorded at 16-bit resolution. TASCAM later introduced the DA-98HR and DA-78HR, which recorded at 24-bit resolution and sample rates up to 48 kHz (for DA-78HR) and 192 kHz (for DA-98HR, suitable for recording high-resolution audio).[4]
In 1995, the TASCAM DA-88 won the Emmy award for technical excellence.[5] The affordability and digital format of the DA-88 led to sales of more than 60,000 units by 1999. At that time, it was the biggest product in the history of TASCAM.[6]Because of its reliability and durability, the DA-88 and its subsequent fellow units continue to be used by aficionados.
