The Whirlwind SPC series of passive microphone splitters are the ideal, expandable solution for permanent
installations. Each unit provides 8 channels of mic level splitting circuitry in a single rack space unit. Depth
is 7.5" including tie bar.

The SPC82 and SPC82P provide one direct and one transformer isolated output per channel, the SPC83
and SPC83P provide one direct and two isolated outputs per channel. Whirlwind transformers are used
throughout. (Available with Jensen transformers, add "JT" to the model number. SPC83 and SPC83P
available with premium Lundahl transformers, add "LUNT" to the model number.) These units are also
available in line level versions SPC82L and SPC83L.

All connections are made via removable Phoenix style connectors included
with the unit. Refer to the legend on the rear of the unit for making proper
balanced connections. The “ISO” outputs will not pass phantom power. Make
sure that the “DIRECT OUT” is connected to the source of phantom power
when not providing power at the splitter.

Alternately, the SPC82P and SPC83P units feature rear terminal connections for
injecting phantom power at the splitter with the optional Whirlwind DCSP1 external
phantom power supply. Phantom power is blocked from the splitter's outputs,
including the direct out. A loop through feature on the phantom connection allows a
single DCSP1 to provide phantom power to multiple units, limited only by total
current draw of up to 500mA.

A set of dipswitches is provided for each ISO output for lifting the ground connection between the input and
output. Normally the switch is left in the “GND” position unless there is a problem with hum or buzz. Then
moving to the “LIFT” position may help reduce or eliminate the problem.

Rear tie-bar is provided for attaching cables securely to avoid accidental disconnects.

DCSP1 (Replaces PS48)
PHANTOM POWER SUPPLY

The DCSP1 is a regulated low-noise 48VDC power supply that can deliver up to 500mA. (Approximately 48
channels of microphones at 10mA each.)
