Introduction to

Stereo Series Converters

The MYTEK Stereo series is an extended family of 1/3 rack units
which includes 96 and 192kHz capable converters, SRC and
Studio Clock. Stereo192 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. Stereo192ADC is currently the world’s highest
performance portable DC powered converter.

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
Stereo192ADC externally. The ultra stable ADC clock
however is a great clock to drive other digital equipment.

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.

DC POWER

7-12 VDC

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.

Battery jack accepts a 7-12 VDC battery for portable operation.
There is no sonic compromise when using battery power.
Power switch is only active with AC Power. Battery with lesser
Voltage is recommended as its capacity will last longer.

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.

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).

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 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 resolution. Sonically they are equal or
better than the most expensive mastering converters.
Stereo192ADC produces 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 Stereo series sound quality and compare it to the sound
of other high end converter units. To download samples log onto:

Stereo192 ADC features include:

- 44.1, 48, 88.2, 96, 176.4 and 192kHz internal sampling
frequencies

- 24 bit resolution

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

- 120dB Dynamic Range

- Switchable precision 10 turn-trimpots or input gain knob

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