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 MidAtlantic screw length is 3/16″ (flathead 632). 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.
