SAFETY PRECAUTIONS
For your safety and the safety of others, be sure to read and understand all safety and operational instructions before attempting to use the HV-3C. WARNING: The HV-3C internal
circuitry car ries lethal voltages. Carefully observe all warnings, precautions, and instructions
on the HV-3C and as described in the instructions supplied with the unit.
1. WATER, MOISTURE, AND SPILLAGE
Do not attempt to use the HV-3C in, near, or around water or in unusually moist environments,
such as near a sink or swimming pool. Prevent liquids or any other materials or objects from
spilling or falling into the HV-3C unit.
2. HEAT AND VENTILATION
Be sure to allow adequate ventilation to HV -3C and avoid using or installing unit in close proximity to heat sources, such as heaters, stoves, radiators, power amplifiers, spotlights, or other heatproducing appliances or equipment.
3. POWER SOURCES AND POWER CORD PROTECTION
The HV-3C Power Supply should be connected to a power source only of the type described in
the operating instructions or as marked on the Power Supply. Route the power cord so that it is
not likely to be walked on or pinched by having objects placed on it. Pay particular attention to
plugs, receptacles, and the point where the AC power cord exits the HV-3C.
4. GROUNDING
For your safety, it is extremely important that the grounding pin of the 3-wire power cable (included with unit) be inserted into a grounding type 3-pin power outlet. If you are unable to insert
the plug into an existing outlet, contact an electrician to install a properly grounded 3-pin power
outlet, preferably that with OFI protection, if available.
5. DAMAGE REQUIRING SERVICE
This unit should be repaired or serviced by qualified personnel whenever:
· The AC power cord has been damaged, or
· A 130 Volt DC microphone cable has been damaged, or
· Objects have fallen or liquid has spilled into any HV-3C unit, or
· The unit does not function properly or exhibits a marked change in performance, or
· The unit has been abused, dropped, or damaged, or
· The unit has been exposed to rain or moisture
6. SERVICING
Lethal voltages are found inside the HV-3C chassis. The user should not attempt to repair or
service this unit. All servicing and/or repairs should be referred to Millennia Media.
If, after reading all instructions, precautions, and warnings, you have remaining questions, please
contact Millennia Media directly before attempting to use your HV-3C. Retain this owner’s
manual as a record of your purchase to aid positive identification in the event of loss.

QUICK START!
READ THIS!! The HV-3C operates with lethal operating
voltages — the voltage inside the HV-3C can kill you.
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 HV-3C High Voltage Microphone
Preamplifier. The HV-3C is the result of meticulous listening tests on numerous circuit, topology, and packaging designs. Your HV-3C is a finely tuned instrument intended for critical
professional applications — we feel it offers the world's most sonically neutral microphone
preamplification. With the emergence of 24+ bit digital audio, recording engineers are faced
with a new requirement for undistorted dynamic range. The HV-3C meets this challenge
exceptionally well.

Before connecting power to the HV-3C, assure that the rear panel voltage selection fuse block
switch is set correctly. In the USA, the HV-3C is shipped with the voltage selection block set to
100-120 V AC. 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 HV-3C enclosure measures 19" wide x 1.75" high x 13" deep and is designed for mounting
into a standard 1U, 19" equipment rack. If the HV-3C is mounted in a road case or other rack
which is prone to strong vibration or shock, it is recommended that the rear of the HV-3C be
supported or otherwise reinforced to withstand such conditions. The HV-3C runs cool but
should be mounted with at least one rack space open above and below the unit.
The HV-3C 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
on the A/C power cord.
HV-3C FRONT-END PROTECTION
Back-to-back Zener diodes protect the super-matched bipolar input transistors against high transient energy spikes common when inserting and extracting XLR connectors. However, to maintain
top performance and protect the HV-3C's sensitive front-end, it is advised that you do not
insert or extract XLR connectors with preamp AC power on. Get in the habit of turning
preamp power off when inserting or removing microphone input or line output cables.
Millennia Media has long enjoyed a reputation for what many engineers call the world's most
musically accurate and dynamically stable microphone preamplifier. W ith B&K (DP A) high voltage
