STT-1
QUICK START
READ THIS!! The STT-1 operates with lethal operating voltages
— the voltage inside the STT-1 can kill you. Never, under any cir-
cumstances, remove the top cover. Refer to a qualified electronics
technician any and all servicing and other operations which require
the top cover to be removed.
Congratulations on your purchase of the Millennia Media STT-1
Origin
tracking and post sys-
tem. The STT-1 is the culmination of meticulous listening tests on innumerable circuit, topol-
ogy, and packaging designs over many years of product design and development. Your STT-1
is a finely tuned instrument intended for critical professional applications — we feel it offers
the world's most sonically versatile "all-in-one channel strip" audio signal path, with the added
benefits of selectable transformer-coupling and vacuum tubes when "euphonic enhancement" is
desired. With the emergence of 24+ bit digital audio, recording engineers are faced with a new
requirement for undistorted dynamic range. The STT-1 meets this challenge exceptionally well.
Before connecting power to the STT-1, assure that the rear panel voltage selection fuse block
switch is set correctly. In the USA, the STT-1 is shipped with the voltage selection block set
to 100-120 VAC. If you change the voltage selection block to 200-240 VAC usage, be sure to
change both fuses to the correct types. See "Rear Panel" instructions for proper fuse require-
ments.
The STT-1 enclosure measures approximately 19" wide x 3.5" high x 15.5" deep and is designed
for mounting into a standard 2U, 19" equipment rack. If the STT-1 is mounted in a road case or
other rack which is prone to strong vibration or shock, it is highly recommended that the rear
of the STT-1 be supported or otherwise reinforced to withstand such conditions. The STT-1
contains a significant number of high voltage vacuum tubes and discrete transistors, all running
in pure Class-A mode. As such, the STT-1 Origin runs warm and should be mounted with at
least one rack screw space open above and below the unit. The rear panel heat sink should also
be given adequate exposure to unrestricted air movement.
The STT-1 is designed on a common ground topology. For high quality operation, and for your
own safety and the safety of others,
do not defeat
the purpose of the earth grounding pin.
STT-1 FRONT-END PROTECTION
Millennia Media enjoys a reputation for what many top engineers and producers call the
world's most musically accurate and dynamically consistent microphone preamplifier — the
HV-3. But this unique design is not achieved without certain operating criteria. Back-to-back
Zener diodes protect the super-matched discrete bipolar input transistors against high transient
energy spikes common when inserting and extracting XLR connectors. To maintain top perfor-
mance and protect the STT-1's sensitive HV-3 front-end, it is advised that you do not insert or
extract XLR connectors with phantom power on. Get in the habit of turning phantom power
off and waiting about thirty seconds for the phantom power to ramp down before inserting or
removing a microphone. This is good advice for protecting a microphone, as well.
