FCC Notice Information for the User
This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant
to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference when the equipment is operated
in a commercial environment. This equipment
generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance
with this instruction manual, may cause harmful
interference to radio communications. Operation of
this equipment in a residential area is likely to cause
harmful interference in which case the user will be
required to correct the interference at his or her own
expense.
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-3R.
WARNING: The HV-3R internal circuitry carries lethal
voltages. Carefully observe all warnings, precautions,
and instructions on the HV-3R and as described in
the instructions supplied with the unit.
Water, Moisture, and Spillage –
Do not attempt
to use the HV-3R 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-3R unit.
Heat And Ventilation –
Be sure to allow adequate
ventilation to HV-3R and avoid using or installing
unit in close proximity to heat sources, such as
heaters, stoves, radiators, power amplifiers,
spotlights, or other heat-producing appliances or
equipment. It is best to leave one rack screw space
between units if possible.
Power Sources and Power Cord Protection –
The HV-3R 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-3R.
Grounding –
For your safety, it is extremely
important that the grounding pin of the 3-wire power
cable (included with 110 Volt units) 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 / CFI
protection, if available.
Damage Requiring Service –
This unit should be
repaired or serviced by qualified personnel
whenever:
· The AC power cord has been damaged, or
· Objects have fallen or liquid has spilled into any
HV-3R 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.
Servicing –
Lethal voltages are found inside the
HV-3R chassis. The user should not attempt to repair
or service this unit. All servicing and/or repairs
should be referred to Millennia.
If, after reading all instructions, precautions, and
warnings, you have remaining questions, please
contact Millennia directly before attempting to use
your HV-3R.
Before connecting power to the HV-3R, assure that
the rear panel voltage selection fuse block switch is
set correctly. In the USA, Canada or Japan, HV-3R 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 HV-3R enclosure measures approximately 17”
wide x 3.5” high x 16” deep and is designed for
mounting into a standard 2U, 19” equipment rack. If
the HV-3R 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 HV-3R be
supported or otherwise reinforced to withstand such
conditions. HV-3R contains discrete transistors,
many running in Class-A bias. As such, the HV-3R
runs quite warm and should be mounted for proper
ventilation with at least one rack screw space open
above and below the unit.
HV-3R 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 power
cord earth grounding pin.
HV-3R Front-End Protection
– Millennia Music &
Media Systems enjoys a reputation for what many
top engineers and producers call the world’s most
musically accurate and dynamically uniform
microphone preamplifier — the HV-3. But this
thoroughbred 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 performance and protect the HV-3R’s sensitive
HV-3 front-end, it is advised that you do not insert
or extract XLR connectors with power on. Get in the
habit of disabling AC power and waiting about ten
seconds for the phantom power to fully “ramp down”
before inserting or removing a microphone. This is
good advice for protecting your microphone
investments, as well.
