Mytek Stereo 192-DSD Digital to Analog Converter – User Manual
Introduction
The Mytek Stereo192-DSD Digital to Analog Con erter is an
ultra-transparent mastering grade digital audio playback
system. Designed around state of the art Sabre 32 bit
con ersion technology, the Stereo192-DSD DAC deli ers
features and sound quality beyond expectation of the most
discerning listener. The DAC is capable of con erting high
resolution PCM audio up to 192 kHz, and DSD up to 128x, all
through high-speed USB 2.0, FireWire, AES/EBU, SPDIF, or
TOSLINK. For the ultimate “plug and play” solution, a USB
1.1 port is a ailable for a dri er free connection that can
handle PCM audio up to 96 kHz sample rates.
The “Preamp” ersion includes RCA analog inputs allowing
the DAC to operate as a preamp. The “Preamp” model is
a ailable in a sil er front panel with the LEDs remo ed for a
cleaner look. These LEDs can also be disabled in the menu on
the both black panel ersions.
The “Mastering” ersion of the DAC includes DSD SDIF
inputs that can be used to connect professional DSD systems.

Menu Operation
The Main Menu is where you control the unit's
configuration. t is accessed by pressing the Menu button.
Once in the menu, turning the rotary encoder cycles through
the options while pressing the encoder advances the
selection. Pressing Menu will go back in levels until you exit
the menu. All settings are preserved when the unit is
powered off.
Inputs
USB 1.1 – Dri er-less, plug-n-play computer input that is
limited to 96kHz.
USB 2.0 – Hi-speed computer input that is capable of 192kHz
and DSD playback. Use of this input requires dri ers
installed on the computer.
FireWire – Hi-speed computer input that is capable of
192kHz and DSD playback. Use of this input requires dri ers
installed on the computer.
S/PD F – Coaxial S/PDIF input capable of recei ing PCM
data up to 192kHz.
AES/EBU – Professional digital input capable of recei ing
PCM data up to 192kHz.
Toslink – Optical S/PDIF input capable of recei ing PCM
data up to 192kHz.
ADAT – Optical ADAT input capable of recei ing PCM data
up to 96kHz. Signal originates from Channel 1-2 only.

olume control or be routed through it. A ailable on the Pre
ersion only.
SD F – Professional DSD input capable of recei ing DSD64x
and DSD128x formats. Mastering ersion only.
Up-sampling
The unit has the capability to up-sample all PCM data to
192kHz sampling rate. This pro ides an analog bandwidth of
100kHz. With up-sampling enabled, it will automatically up-
sample PCM data. It will automatically turn off for DSD data.

Mytek Stereo 192-DSD Digital to Analog Converter – User Manual
Filters
There are se eral filtering options for both PCM and DSD.
The filters affect how upper “out-of-audio” band
frequencies are rolled off.
PCM
Sharp – Brickwall cutoff at ½ sampling rate.
Slow- Gentle cutoff with some aliasing.
DSD
Cutoff frequency – 50, 60, or 70 kilohertz cut off.
Gentle Filter to reduce high frequency noise.
Sync
nternal Sync – Incoming clock signal is re-clocked by the
con erter's ultra-low jitter internal crystal oscillator.
nput Sync – Incoming clock signal is used as the reference.
Word Clock – Deri es the clock signal from the Word Clock
input.
Volume Control
There are se eral methods of olume control a ailable:
Analog – The output le el is controlled by a programmable
analog fader. This also allows independent le el control
o er the main output or headphone output.
Digital – The output le el is controlled digitally inside the
con erter chip. This may measure better than analog control,
but usually doesn't sound as good. This does not allow for
independent le el control of the main and headphone
outputs.
Bypass – Relay bypass of all faders for the cleanest output
path possible. Only the main outputs are affected while the
headphone output is adjustable.
Volume Trim
This setting allows you to choose how you want 0dB VU to be
represented in dBFS. You can set it from -14dB to -18dB.
Disable is fixed at -18dB correlating to 0VU at 1.228 olts RMS
measured between pins 2&3 of XLR outs.
Sync options are only
available for S/PD F,
AES/EBU, Toslink,
ADAT, and SD F

Function Buttons
The two buttons, FN1 and FN2, are user programmable
switches. Each button's function is set by choosing it in the
menu. The following options are a ailable (* PCM Only):
nput – Allows the user to select 3 user “presets,” Input A,
Input B, Input C; Each input can be assigned to either SPDIF,
AES, Toslink/ADAT, USB1, USB2, Firewire, Analog/SDIF or
none. The none allows to only switch between 2 Input
presets.
Mute – Mutes the audio.
Phase – In erts the signals phase.
Mono *– Sums left and right to mono.
L-R *– Subtracts one channel from the other, canceling out
mono information while lea ing the stereo information.
Mid Side *– A combination of Mono (L+R) and L-R, the
mid signal is the sum of L and R (mono) and the side signal
is the stereo information from the L-R operation.
Dim Vol – Instantly lowers the le el by 20dB.
Display
There are se eral choices pertaining to the display.
Brightness – Of the LED display.
Meters – Turns the signal le el meters on or off. (A ailable
on black panel ersions only.)
Auto-Off – This will turn the display off after the selected
amount of time. A dim dot will stay lit to show that the unit
is operational.
Remote
Enable – On and Off. Allows the Stereo192-DSD DAC to be
controlled by a Remote Control
Mode - Select the remote type Apple or RC 5.
Firmware
Version – Displays the current Firmware ersion.
Restore - This will restore all of the unit's parameters to the
factory default.

DRIVER INSTALLATION
USB 1.1 PC and MAC
1. Connect the Analog Outputs to your powered
speakers/amplifier. Balanced connections (XLR) are typically
for professional audio equipment while unbalanced
connections (RCA) are typically for consumer audio
equipment.
2. Connect the unit to your computer using USB1.1.
3. Turn on both the computer and the converter, then your
speakers/amplifier.
4. By default the unit will be set to USB1.1 input. You will
now have to set the unit as the default playback device in
your operating system's sound properties.
USB 1.1 is a simple plug-
n-play solution that
requires no drivers. The
benefit is that you can
very quickly and easily
set up the unit for
computer playback. The
drawback is that you are
limited to 96kHz as the
maximum sampling rate.
Using USB 2.0 or
FireWire will allow you
to playback all sample
rates up to 192kHz and
DSD. These setups are
explained in subsequent
chapters.
