Input volume knob sets the input
sensitivity with range from mute to
+4dB=-10dBFS. This is factory
default. The knob can be disabled
with internal jumpers which can
select either the knob or internal
precision 10 turn trimpots. Refer to
"Internal jumper settings" for details.

Sample rate selection.

sample rate. When
used with external clock
select FS closest
matching that of
supplied external
wordclock.

Peak meter in -dBFS.
The red LED marked
"0" corresponds to 1
sample overload.

Selects output wordlength as stated. The 20 and
16 bit "flat dither" setting corresponds to signal
dithered with flat dither. Supershaper HR is a
high performace wordlength reduction algorithm
similar to Pow-r(tm). Flat dither is recommended
for multitracking, while Supershaper can be used
for printing final mix to CD-R.

Internal sync provides the best clock stability
(10ps) and thus the best conversion. External
sync is intended for complex systems. It can be
a standard wordclock signal or Protools (tm)
256X superclock. Refer to "Internal jumper
settings" for details. Since internal clock
generator is top notch, there is no sonic benefit
from clocking Stereo96ADC externally.

Line power is 115VAC/50/60Hz
(factory default) or
230VAC/50/60Hz switchable by
internal switch accessible after
removing the top cover. 1 Amp
slow blow 20mm fuse is also
accessible under the cover.

Wordclock input (factory default)
can be set to alternatively accept
256 Protools (tm) Superclock (Mix
systems). Refer to "Internal jumper
settings" for details. 75 Ohm
termination (default off) can also be
set inside unit.

Analog inputs accept a
range of signals from +4dB
balanced down to
consumer unbalanced.
Refer to "Internal jumper
settings" for details.

Wordclock output provides high current drive and
a very stable low jitter clock. It can be used as a
superior house clock to clock or synchronize
other digital equipment. Running Stereo96ADC
on internal clock and slaving the rest of
equipment to Mytek clock is the recommended
setting for best sonic performance.

AES/EBU and SPDIF outputs are
simultaneous. They operate in "single wire"
mode for all sampling frequencies. These
outputs can be used to externally clock other
equipment with the same effect as wordclock
output. Clocking via AES/EBU line is
recommended

when cables are very

long (over 20ft).

Introduction to

Stereo96 Series Converters

The MYTEK Stereo96 series consists of two 1/3 rack units- the
Stereo96 ADC and the Stereo 96 DAC. They are also a part of
extended family of 1/3 rack units which also includes 192kHz
capable converters, SRC and Studio Clock. Stereo96 converters
can be used as stand-alone devices for variety of studio
applications such as mastering, recording and playback, whenever
the highest quality conversion is required.

Users choose Mytek 8X96 converters primarily for their
outstanding sound quality. The sound of Mytek converters can be
described as "transparent". We design our converters to be as
faithful to the signal as possible, rather than the philosophy of
some other manufacturers who offer "analog" or "tube" sounding
converters. Mytek converters are closest to a straight wire, which
is especially evident when used at full 24/96 resolution. Sonically
they are equal or better than the most expensive mastering
converters. Even when used in 16 bit mode, the Stereo96
converters produce 20dB (10 times) less distortion than typical
converters found in budget recording equipment. On Mytek
website you can find and download various sound samples to
evaluate Stereo96 series sound quality and compare it to the sound
of other high end converter units. To download samples log onto:

Stereo96 ADC features include:

-

44.1, 48, 88.2 and 96kHz internal sampling frequencies

-

-

High performance SuperShaper-HR™ psychoacoustic
noiseshaping algorithm for 16 bit output

-

Switchable precision 10 turn-trimpots or input gain knob

-

Wordclock output can be used as a hi-end house clock.
