LPE-2
QUICK START
READ THIS!! For your protection, never under any circumstances
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 LPE-2 Analog Legacy archive refer-
ence system. The LPE-2 is the culmination of meticulous listening tests on innumerable circuit,
topology, and packaging designs over many years of product design and development. Your
LPE-2 is a finely tuned instrument intended for critical professional applications — we feel it
offers the world's most sonically invisible
and versatile phonographic front-end.
Before connecting power to the LPE-2, assure that the rear panel voltage selection fuse block
switch is set correctly. In the USA and Canada, the LPE-2 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
requirements.
The LPE-2 enclosure measures approximately 19" wide x 3.5" high x 15" deep and is designed
for mounting into a standard 2U, 19" equipment rack. If the LPE-2 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 LPE-2 be supported or otherwise reinforced to withstand such conditions. The
LPE-2 contains 50V discrete transistor amplifiers, with most running in Class-A bias. As such,
the LPE-2 Analog Legacy runs warm and should be mounted with at least one rack screw space
open above and below the unit.
The LPE-2 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 AC plug earth grounding
pin.
LPE-2 FRONT-END PROTECTION
Millennia Media enjoys a reputation for what many top engineers and producers call the
world's most musically accurate and dynamically uniform audio 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 that can occur when inserting and extracting connectors. To maintain top perfor-
mance and protect the LPE-2's sensitive HV-3 front-end, it is advised that you do not insert or
extract XLR or phono connectors with LPE-2 power on. Get in the habit of turning the unit
off before inserting or extracting XLR's or RCA plugs on the inputs.
