DATAPORT V2-
What It Is- The DataPort V2 is used for connection to optional
QSC DataPort accessories. DataPort accessory devices can
provide remote cinema monitoring, DSP, filter and crossover
functions.
The “V2” DataPort connection is a “version-2” of QSC’s original
DataPort. It has a reduced feature set from the original, while
maintaining essential amplifier monitoring capability.
It does not
supply +15 VDC power required by some DataPort accessories.
FEATURES & SETUP-
DATAPORT V2
Where It Is- The DataPort V2 connector is
on the rear panel, left side and center.
Using the DataPort V2- Some DataPort accessories plug
directly in to the DataPort while others use an interconnect-
ing QSC Dataport cable. Consult the accessory’s
documentation for recommended mounting and interconnect
information.
Do not use the XLR or terminal block connections for inputs
when the DataPort V2 is used as the input signal source. If
you do, the signals from the DataPort V2 and regular inputs
will be mixed, possibly with unexpected results.
What Can I Connect to the DataPort V2?
Consult your QSC representative for up-to-date
accessory compatibility. QSC has several DataPort-
based accessories available like the:
DSP-3 Digital Signal Processing Module
XC-3 Crossover
SF-3 Subwoofer Filter
LF-3 Low Frequency Filter
DCM Crossovers & Monitors

Daisy Chaining to Other Amplifiers
While Using the DataPort V2 for
Input Signals-
If the incoming audio
input signal is through the DataPort V2,
the XLR and terminal block connectors can
be used to daisy chain the input signal to
other equipment. The signal at these
connectors will be about 10 dB lower (in
voltage) than the incoming DataPort V2
signal. The illustration to the right shows
the basic daisy chain hookup. Note that
the XLR connections may also be used for
daisy chaining the audio to other devices.
Daisy chaining may not be possible with
accessories that cover the XLR and/or
terminal block connectors.
Daisy chaining the DataPort V2 input to other devices using the terminal block connectors.
NOTE! The DataPort V2 can only supply a maximum
current of 40 mA. Some accessories, such as the
DSP-3, require more than 40 mA to operate. Use an
external power supply with such accessories.
