1 – Introduction to the DA-98
The TASCAM DA-98 is a digital audio multitrack
recorder designed for use in a variety of applica-
tions, including video post-production and audio
multitrack work.
recorder designed for use in a variety of applica-

It records 8 tracks of full-quality digital audio on
standard Hi8 video cassettes using a specially-
designed transport and head mechanism. Using
this medium, up to 108 minutes of continuous
recording is possible on a single NTSC “120”
tape.

Recording is carried out at a full 16 bits of resolu-
tion, and digital data may be input at 16, 20 or 24
bits of resolution. Analog signals are converted to
digital data using 64 times oversampling delta-
sigma techniques.

The DA-98 builds on the foundations laid by the
TASCAM DA-88 and DA-38 digital multitrack
recorders, and retains compatibility with them.
Tapes recorded on one of the DA series can be
replayed and overdubbed on any other machine in
