DCIO/DCIO-H

The Digital Cinema Input/Output for Q-SYS (DCIO) is a cinema-specific interface that serves as the audio I/O for each screen in a Q-SYS enabled cinema complex.

Note: This topic provides an overview of the DCIO/DCIO-H peripheral. For installation and wiring instructions, see the Hardware User Guide online.

Hardware Attributes

Front Panel

OLED display – Displays information about the DCIO's settings and status.
NEXT button – Cycles through the OLED information pages.
ID button – Locates the DCIO in Q-SYS Designer GUI and Configurator.
POWER LED – Illuminates blue when the DCIO is on.
MUTE LED – Illuminates red when the DCIO master mute is engaged.
MUTE button – Enables/Disable master mute.
LEVEL rotary – Adjusts the master level.

Rear Panel

All inputs and outputs are configured in Q-SYS Designer software running on the Q-SYS Core to which the DCIO is connected.

Note: For wiring information and pinouts, see the Hardware User Guide online.

MIC / LINE INPUT – Standard three-conductor XLR connector, balanced input, phantom power available in Q-SYS Designer. Used for: mono, non-sync sources including microphone for in-auditorium announcements, and SPL metering.
Hearing Impaired and Visually Impaired Outputs (H.I. and V.I.) – Five-terminal Euro-style receptacle, balanced outputs, used for: hearing- and / or visually-impaired special mixes. The receptacle label provides a pin-out of the signals. The ground is common to both.
Tip: A standard three-terminal Euro-style connector may be used if only one output is required. Make sure the plug is all the way to the right, or all the way to the left of the five-terminal receptacle.
RELAY OUTPUTS – Two six-terminal Euro-style receptacles, mechanically de-coupled control outputs, floating relay contacts, rated for 30 VDC at 1A. Each relay output has one common contact (C), one normally open contact (NO) and one normally closed (NC) contact. When not energized, C is connected to NC and NO is not connected. When energized, C is connected to NO and NC is not connected. Used for controlling curtains, lighting, etc.)
AES3 INPUTS – RJ45, CAT-5 or better to connect to sources using the same type connector and pinout.
AES3 1–8 – AES3 pairs 1 through 4 (digital audio channels 1–8)
AES3 9-16 – AES3 pairs 5 through 8 (digital audio channels 9–16)
Used for primary content audio from the server or media block.
Note: The AES3 connectors are NOT network connections.
LAN connections – RJ45, CAT-5E or better.
LAN A – Used for primary Q-LAN connection, required.
LAN B – Used for redundancy.
POWER ON / OFF switch
IEC connector – AC mains power connector
Line Inputs (LR) – Standard 3.5mm TRS jack, unbalanced, stereo, analog, line-input. Used for non-sync sources appropriate for alternative content, advertising, corporate or live event feeds.
Monitor Outputs – Five-pin, Euro-style connector; three-pins for Line and two pins for Speaker. The supplied connectors have an extended tab with holes for securing the wiring to the connector. Refer to the pin-out label on the rear panel for wiring.
- Line – The Line output provides a balanced output at 14 dBu, via three pins of the Euro-style connector.
- Speaker – Powered output, 10 watts maximum, via two pins of the Euro-style connector.
AUTOMATION INPUTS – RJ45, contact closures. The Automation Inputs can be connected to relay contacts or a switch (control presets, mute etc).
RS-232 Serial Communications – Three-pin Euro-style connector for (Rx), transmit (Tx) and ground pin. Used for third-party control or automation.
HDMI In – DCIO-H model only. Extracts audio from incoming HDMI stream and passes the stream directly to output HDMI port for connection to a downstream video device. Up to 8 channels of PCM audio are supported. Additionally, Dolby Digital Plus™ and DTS-HD® decoders will be automatically applied if those bitstreams are detected.
HDMI Out – DCIO-H model only. See HDMI In.

OLED Screens

Design Status

Device – The name of the Core as defined in Q-SYS Designer.
Design – The name of the currently running design.
Status –
- OK – Audio is good, hardware is good.
- Compromised – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists.
- Fault – Audio is not passing, or hardware is malfunctioning or mis-configured
- Missing – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware.
- Initializing – Starting the firmware, configuration update, and the design. Audio is obviously not available during initialization.
- Not Present – A virtual component in the design, that is designated as Dynamically Paired, and Not Required, has no hardware assigned to it.

System Status

Firmware – The version number of the firmware currently installed on the DCIO.
Temp – The current chassis temperature of the DCIO.
Level – The current master level setting -100 dB to +20 dB. Adjust with front-panel rotary or in Q-SYS Designer.
Mute – The current master mute status. Controlled by front panel Mute button or in Q-SYS Designer.

LAN A

You can edit this information in the Q-SYS Configurator.

Static, Auto or No Link – Displays next to LAN A, indicates if the device's IP Address is Static, Automatic, or No Link.
IP Address – The IP Address assigned to the Core's LAN A. LAN A is the primary Q-LAN connection to the Core, and is required.
Net Mask – The Net Mask assigned to the Core.
Gateway – The Gateway assigned to the Core.

LAN B

LAN B is used for redundancy, and is not required. The information is the same as LAN A.

AES 1–8 and AES 9–16 Channel Status

You must have AES 9–16 Enabled in Q-SYS Designer to see channels 9–16.

Mute – Displays a "muted loudspeaker" when the channel is muted.
Signal – Displays a blinking or solid circle when there is a signal present on the associated channel, an empty circle if there is no signal.

HDMI 1–8 Channel Status

Mute – Displays a "muted loudspeaker" when the channel is muted.
Signal – Displays a blinking or solid circle when there is a signal present on the associated channel, an empty circle if there is no signal, and nothing if that channel doesn't exist in the current stream.
Bitstream Type – Displays the type of bitstream detected at HDMI input.
Sample Rate – Displays the sample rate detected at the HDMI Input.

Analog In Channel Status

Mute – Displays a "muted loudspeaker" when the channel is muted.
