Power:
12V AC - The 12V AC Brick™ is designed to function properly with an input power of 11-13V AC.
The Brick will not operate from a DC voltage. A 2.1mm P5 style connector is used for the power input. If
the input voltage is a grounded system, the center pin of the P5 is the power connection and the barrel is the
ground side. All ProSeries units are shipped with a 12VAC, 600mA floating power supply that eliminates any
ground loops through the power supply connection.
FlewPwr - The FlexPwr Brick™ is designed to function properly with an input power of 10-28V AC
(ungrounded) or 12-32V DC (grounded or ungrounded). A 2-pin header (Phoenix Contact #1881448) style
connector is used for the power input. The 12V AC, 600mA wall transformer provided with the product provides a floating power source that has been designed to eliminate any ground loops through the power supply
connection.
Input:
The input for this product consists two Terminal Block connectors (one per channel). An audio signal
with excessive DC component (or offset) will cause the VAC Brick to malfunction. The audio signal needs to
be within -4V to +4V.
Outputs:
The VAC Brick has eight audio outputs (four per channel) consisting of Terminal Block connectors.
Unused outputs do not need to be terminated for proper operation of the Brick.
Gain:
Unity Gain, Global Driver - The signal amplitude at each output is identical to the input signal,
Unity Gain, Individual Drivers - The signal amplitude at each output is identical to the input signal,
Global Variable Gain - The signal amplitude at each output is variable, and all output signal

with individual drivers.
amplitudes are adjusted together with one control (for a total of 4 outputs
per gain control).
Variable Gain - The signal amplitude at each output is variable, and is independent of all
other outputs. Aseparate gain control is provided for each output.
