Using Q-SYS with Dolby® Atmos

Rev. A, 28 January 2019

Q-SYS AND DOLBY® ATMOS.

The versatility and processing power of Q-SYS and Q-SYS Core Processors make them an ideal cinema audio infrastructure
to implement a Dolby Atmos system on. The QSC cinema core processor family comprises two models, the Core 110c and the
Core 510c.

Q-SYS BEST PRACTICES FOR CINEMA

Use this check list to be sure you’ve adopted the best practices for launching a Q-SYS network for cinema.

• Use qualified, properly configured network switches. QSC now makes available a line of switches that are precon­figured for most Q-SYS applications but also easily adaptible for more specialized ones. For more information on
Q-SYS NS Series network switches or for guidance on identifying and setting up third-party network switches,
see https://www.qsc.com/systems/products/q-sys-platform/products-peripherals-accessories/

network-switches/q-sys- networking-solutions/

• For information on general third-party switch requirements for Q-LAN, see https://www.qsc.com/resource-files/
productresources/dn/3rd_party_control/q_tn_sys_dn_qsys_generalswitchrequirements.pdf

• Use separate switches for each LAN unless you have the IT support resources available to set up VLANs on managed
switches.

• Disable PTPv2 (clock) on any network interface controller (NIC) that connects to the house/control network (typically on
LAN B).

• Use a separate PTP clock domain for each core processor.

• For sharing music, use WAN TX and RX.

• Isolate all Q-SYS devices into LAN A.

• There should be only one gateway per core processor.

• Do not duplicate any IP addresses or overlap any subnet ranges.

A typical cinema system with Q-SYS has three networks:

• QLAN, where all the Q-SYS components reside and are interconnected on LAN A.

• Management network, used by the theatre management system (TMS) to communicate commands, schedules, and status
with the individual components of each stadium.

• Media network, used exclusively for media or content transfer. Each server receives via this network both its media to be
played and also its key delivery messages (KDMs) that enable it to be played with the appropriate server features.
