+48V turns the phantom power supply on.
Protecting Against Electrostatic
Discharge – Static electricity can harm
delicate components on the HV-35 board.
To prevent static damage, discharge
static electricity from your body before
you touch any jumpers or switches with
the cover removed. You can do so by
touching an unpainted metal surface on
the API rack’s chassis.
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.
Do not install or remove the
module until the rack’s power
is off.
Compatible Racks – The HV-35 is
designed to work in an API 500VPR or
Lunch box rack. If you are using another
brand, be sure it meets or exceeds the
API spec.
HPF (High Pass Filter) rolls off low
frequencies below 80 Hz at 6 dB per
The HV-35 power consumption is:
+45mA,–25mA nominal
+75mA,–25mA with +48V selected
Inst Input (Instrument Input) is for
high impedance sources such as bass
guitars. It makes the Hi-Z Instrument
input active.
Signal Present (green) and Peak
(red) LEDs indicate signal present at
-46dB and peaks at +22dB.
Gain is a continuously variable gain
control. It has a high gain jump near full
clockwise for low level signals.
Pad – Attenuates the input signal after
the gain stage by 13.5dB
Pol Flip (Polarity Flip) inverts the
signal’s polarity. This can be useful in
multiple mic setups to change the
interaction between them.
