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

Sample rate selection. Sets the
desired 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.

Optical Toslink output can output

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

both SPDIF and ADAT formats.
SPDIF format allows to interface
with Mac computers including
Powermac laptops (up to 96kHz).
ADAT format is enabled and
assigned by internal dip switch.

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

Analog inputs accept a
range of signals from
+4dB balanced

and
consumer unbalanced.

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. WCK IO can also be set to 256
“superclock” format used in older Protools
systems. Superclock/wck is selected using

AES/EBU SPDIF outputs are

, and OPTICAL
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

especially

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
an 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 a variety of studio
applications such as mastering, recording and playback,
whenever the highest quality conversion is required.

Users choose Mytek 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 follow a 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 the Mytek
website you can find and download various sound samples to
evaluate the Stereo96 series sound quality and compare it to the
sound of other high end converter units. To download samples

Stereo96 ADC features include:

- 44.1, 48, 88.2 and 96kHz internal sampling frequencies

- Ext. wordclock sync 25-100kHz or 256x Superclock(tm)

- 120dB Dynamic Range

- 24 bit resolution

- 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.
