P4 • Quad Precision Phantom Network
INTRODUCTION: The 4 channel Precision Phantom Network™ renders power for
unimpaired microphone operation. Each channel of the P4 has a stable, high current,
independently regulated supply. This eliminates signal cross-coupling, improving
channel isolation and imaging. Precision matched componentry maintains tight
impedance balance for greatest signal yield and lowest noise.
The P4 is the perfect companion product to our JR4 dc-coupled mic preamp.
However, the P4 can be used with any mic preamp for improved audio fidelity. This is
because it is the microphone’s performance, rather than the preamp, which benefits from
the P4. This improvement then flows through the remaining signal chain. Please try for
yourself!
DC POWER INPUT: A single 5-pin male XLR connector is located on the rear panel. Use
in conjunction with a Pueblo Audio DC power cable to connect to the PS34 power
supply.
WARNING: Do not modify or make dc power cords that split, mult, or ‘y’
power distribution. Do not power from third-party products, damage may
occur. Only designed for use with Pueblo Audio products.
POWER INDICATOR LED: Light emitting diode on left of front panel indicates unit
power status:
PHANTOM POWER ON /OFF SWITCH: Energizes each channel’s phantom power
voltage regulator. Note that this switch is not in the audio signal path. The regulation
circuit output is always in-circuit. When using non-phantom powered devices, please
patch around the phantom channel and connect directly to the preamp input.
PHANTOM POWER ON /OFF LED: Light emitting diode indicates on/off status for each
channel.
*NOTE: The above P4 information also applies to the Precision Phantom Network
channels of the JR2/2. Since each channel is an independent module, short xlr
interconnects are required to connect to a preamplifier channel.
