CAUTIONG!:
Elevated Operating Ambient
- If installed in a closed or multi-unit rack assembly, the ambient operating temperature of
the rack environment may be greater than room ambient. Consideration should be given to ensure that the maximum operating
temperature of 50°C (122°F) for the I/O Frame, and 45°C (113°F) for the Core, is not exceeded.
Reduced Air Flow
– Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of
the equipment is not compromised.
Circuit Overloading
– Consideration should be given to the connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on over-current protection and supply wiring.
Connections
AC Power Cord
Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the
Q-Sys product. Plug the AC line connector into an AC outlet. The power supply on the Q-Sys
Core and I/O frame accepts 100 — 240 V, 50 — 60 Hz. If a different type of IEC power cord is
required than that supplied with the product, consult QSC’s Technical Services Group.
Q-Sys™ Network
Connect one end of a data communications cable (CAT-6 rating or better) terminated with an
RJ45 plug into the LAN A (and optionally LAN B) receptacle on the rear panel of the Q-Sys
product. Ensure that the lock tab on the cable engages with the RJ45 receptacle.

Mic/Line Inputs, Line Outputs, AES3 I/O
Several of the optional audio I/O Cards accept Euro style (also known as Phoenix) three-
terminal plugs.
(Figure 2)
When these cards are ordered in the product configuration a shop
kit containing the mating plugs is included in the carton contents. Plug the Euro terminal block
plug into the appropriate input or output receptacle on the Q-Sys Audio I/O Card’s panel face.
The connection pinout is printed on the Q-Sys Audio I/O Card mounting bracket. Refer to the
illustrations in the right-hand column of this page for balanced and unbalanced connections
(analog connections only – AES3 connections always require all three conductors).
DataPorts
The Q-Sys DataPort I/O Card is intended to interface to QSC amplifiers with v1 DataPorts. This
is the all-capable version 1 DataPort specification, supported on CX, DCA, PowerLight™, PL2,
and PL3 Series amplifiers. All DataPorts use the HD15 connector format and connect to QSC
amplifiers via data communications cables having male HD15 connectors.
(Figure 3)
These appear to be common VNA cables but they are not. Many off-the-shelf VNA
cables MINHT work with satisfactory results, however it is also quite possible
off-the-shelf cables will give less-than-satisfactory results, and could even cause
damage to QSC amplifiersG The QSC DataPort specification requires that all
conductors be present, as well as shielding over those conductor pairs used for
the audio channels to the amplifier. Therefore, QSC recommends the use of QSC
DataPort cables exclusively, which are available in a variety of lengths from QSC.
Use of any non-QSC DataPort cable may void the warranty.
To connect a DataPort cable between a Q-Sys DataPort I/O Card and an amplifier DataPort,
attach the cable’s male connectors to the HD15 ports and finger tighten the thumb screws on the connector.
