PS34 • Central Power Supply Unit
INTRODUCTION: The Pueblo Audio PS34 power supply provides 160 watts of linearly
regulated DC power. It can power from one to four Pueblo Audio products (16 channels
max.). It will operate reliably under significant ac service voltage sag due to brown outs.
LOCATION: The PS34 is an external, centralized power source. This beneficial
arrangement allows heat, vibration, and residual emi of the power supply to be placed at a
distance from sensitive audio circuits. It is recommended that the PS34 be located as far
away from other audio devices as is practical.
The PS34 is a high power unit, much like a speaker power amplifier. The same
thermal precautions taken with power amplifier operation should be adopted. Heat
dissipation relies on convection cooling. Care should be taken to insure the unit is kept in
a well-ventilated environment to avoid overheating. At least one rack space should be
kept free above and below the unit when installed in a rack.
AC INPUT (US): 115Vac, 50-60Hz, 0.50A.
AC INPUT (EU): 230Vac, 50-60Hz, 0.25A
DC OUTPUT: Four 5-pin female XLR connectors are located on the rear panel. Used in
conjunction with Pueblo Audio DC power cables, connects DC power to individual
Pueblo Audio products (P4, JR4, JR2/2, and GM2).
WARNING: Never connect more than four products to the PS34 or the
power capacity may be exceeded. Do not modify or make dc power cords
that split, mult, or ‘y’ power distribution. Do not power other third-party
products, damage may occur. Only designed for use with Pueblo Audio
products.
POWER INDICATOR LEDs: Three light emitting diodes indicate power status:
P+ indicates the positive high voltage is on for the precision phantom networks.
V+ indicates the positive bipolar voltage is on for amplifier powering.
V- indicates the negative bipolar voltage is on for amplifier powering.
