AudioFlex Systems (systems requiring a variety of audio formats)
Digital IQ’s external audio connections enable systems in which multi-channel audio is able to be
routed to capable zones, while 2-channel audio is routed to zones with this requirement.
This sort of system is possible with the following setup in place:
½½
The source device has received an EDID handshake supporting multi-channel audio (ie. Default
EDID 2, 3, 5, 6, 8 or 9 or an EDID copy from a connected AV Receiver).
½½
The source features at least two audio output connections:
»»
Multi-channel audio is output from the source’s HDMI connection and is connected to the
HDMI input connection on the Digital IQ’s input card.
»»
2-channel audio is output from the source’s L/R Analog or PCM Digital (recommended)
output and is connected via RCA to the Digital IQ’s external audio connection on the
respective input card. Note that it is often necessary to enter your source devices Digital
Audio setup menu to ensure that the PCM Digital Audio output is limited to 2-channel.

Selection of the source by a multi-channel capable zone chooses video from the HDMI input
connection and audio from the HDMI input connection
»»
Selection of the source by a 2-channel capable zone chooses video from the HDMI input
connection and audio from the external audio input connection (L/R Analog or PCM Digital)

Two sources connected via HDMI and PCM Digital Audio. For AudioFlex systems, the HDMI
connections carry video + multi-channel audio, while the PCM Digital audio connection carries
2-channel audio
Example: A system in which Output Zone 01 supports multi-channel audio while Output Zone 02
requires 2-channel audio and both zones would like to select source 08.
Switching selection by the multi-channel capable zone:

»»
Where xx = 01 = Output Zone which supports multi-channel audio
»»
Where yy = 08 = Input Card Number (video & audio)
»»
Where z = HDMI Input Audio Location
Switching selection by the zone requiring 2-channel audio:
SPO02S082
»»
Where xx = 02 = Output Zone which requires two-channel audio
»»
Where yy = 08 = Input Card Number (video & audio)
»»
Where z = PCM Digital Input Audio Location
7. Audio Distribution Features
Digital IQ features external audio output connections that are active in many cases and are ideal
for integrating with amplifiers, multi-zone audio distribution systems, or AV Receivers. The external
audio outputs feature a variety of audio control options such as Volume Control, Balance, Multi-
Band EQ, and Lip-Sync Control that is able to add up to 600ms delay.
Refer to the following Audio Processing Chart to determine the activity of the external audio output
connections in your application:

No No Yes No
DOLBY/DTS Yes No Yes No
HD Audio No No Yes No
Configuring the Audio Distribution Connections
Although it is possible to configure much of your Digital IQ’s Audio Distribution settings via the front
panel, it is recommended to do so via RS-232 because of the superior status feedback possible.
Please note that there is a single audio processor per output card, therefore any feature configured
applies to the respective output card’s HDMI, RJ45, and External Audio connections.
