HV-35P User Guide
revised 0303223js
Signal Present (green) and Peak
(red) LEDs
indicate signal present at
-46dB and peaks at +22dB.
Pad
–
Attenuates the input signal after
the gain stage by about 14dB.
Pol Flip (Polarity Flip)
inverts the
signal’s polarity. This can be useful in
multiple mic setups to change the
interaction between them.
+48V
turns the phantom power supply on.
Avoid connecting or disconnecting
mics with the +48V on (hot
patching). This can damage the
mic, preamp and make some very
loud pops that can damage your
monitoring system and ears.
Ribbon Mic
DC couples the mic to the
gain stage and also provides an additional
10dB of gain. Use with any Ribbon or
Dynamic mic (like an SM-57). A mic
requiring phantom power will not work in
this mode.
HPF (High Pass Filter)
rolls off low
frequencies below 80 Hz at 6 dB per
octave.
Inst Input (Instrument Input)
is for
high impedance sources such as bass
guitars. It makes the Hi-Z Instrument
input active.
Gain
is a continuously variable gain
control. It has a high gain jump near full
clockwise for low level signals.
External Power Supply –
The HV-35P is
powered by a 12V DC, 5 amp, universal
voltage (100 to 240 VAC) line lump power
supply provided with the unit.
It can also be powered by Li-Ion battery packs
that produce 14.8V DC and automatically cut off
at 12V DC. If it doesn’t have a cut-off circuit, it
may damage the unit.
Rack Tray Mounting
– Maximum Mid-
Atlantic screw length is 3/16" (flathead 6-
32). If you use a longer screw it will damage
the circuit board.
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.
Water, Moisture, and Spillage
–
Do not
attempt to use the HV-35P 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-35P unit.
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.
