CONVENTIONAL MIC INPUTS "48V IN " 

Conventional 3-pin female XLR input jacks for use with 
all conventional balanced microphones, both phantom 
and non-phantom powered. Pr48V Phantom 
powering. Standard input impedance is approximately 
6,200 ohms. Pin 1 is ground. Pin 2 is positive polarity. 
Pin 3 is negative polarity.  
 
Connector contacts are Neutrik gold and Super C plated. 
It is suggested that XLR cable connectors used with the 
HV-3 series preamp employ identical plating to minimize 

corrosion if you are not plugging the cables in often.

HIGH VOLTAGE MIC INPUTS "130V IN " Four pin 

female XLR connector for use only with DPA (B&K) 
models 4003, 4004, 4009, and 4012 microphones. On 
HV-3 series preamps without this option, a plate will 
cover the unused XLR holes. Pin 1 is ground. Pin 2 is not 
connected. Pin 3 is +130 Volts DC power and pin 4 is 
unbalanced audio signal. 
 
Connecting anything other than the above listed DPA 
models to this connector may result in serious damage 

to microphone, the HV-3 series preamp, or both. 
Connector contacts are Neutrik gold and Super C plated. 
It is suggested that XLR cable connectors used with the 
HV-3 series preamp employ identical plating to minimize 
corrosion if you are not plugging the cables in often.

LINE LEVEL OUTPUTS "OUT" 

Conventional three pin male XLR connectors providing 
balanced, line level microphone output. Pin 1 is ground. 
Pin 2 is positive polarity. Pin 3 is negative polarity. The 
line level output is capable of driving 600 ohm loads and 
long, high capacitance cables. Outputs may be 

configured in an unbalanced configuration by either 
grounding one of the audio polarities (pin 2 or pin 3), or 
taking one audio polarity directly as an unbalanced 
signal (recommended). In the former configuration, the 
output is automatically decreased by 6 dB. Connector 
contacts are Neutrik gold and Super C plated.

AC VOLTAGE MAINS SELECTION "100-120" or 

"200-240" A power entry module with a removable fuse 
holder block. This fuse holder block is selectable for 100 
to 120 Volt or 200 to 240 Volt worldwide mains 
powering.  

 
The fuse block contains two fuses — one fuse is in series 
with the hot power line while the other fuse is in series 
with the neutral power line. Both fuses must be 

installed. To change the mains voltage selection, remove 
IEC power connector and assure that the HV-3 series 
preamp is not connected to mains power.  
 
With a non-conductive tool, gently pry the fuse block 
away from the power entry module. Remove the two 
fuses and replace both with type as shown below. Orient 
the fuse block so that the proper voltage is shown and 
reinsert into the power entry module.  
 
Double check that the fuses installed correspond to the 
AC mains voltage range which is shown on the exterior 

panel. Gently push the fuse block back until flush and 
snug.

FUSES 

5 x 20 mm,1000 mA, slow blow, 250 V, Littelfuse 218 or 
equiv.. 
 
POWER ENTRY "IEC Power Receptacle" 
An IEC-type AC line-power receptacle for use with 
removable cords. Use only the power cord 
provided with the HV-3 series preamp unit or equivalent 
U/L approved type SV, SVT, SJ, or SJT AC power supply 

cord. Do not defeat the third pin earth ground.
