About Dante
This product features Dante technology as a protocol to
transmit audio signals. Dante is a network protocol
developed by Audinate. It is designed to deliver
multi-channel audio signals at various sampling and bit
rates, as well as device control signals over a Giga-bit
Ethernet (GbE) network. Dante also offers the following
benefits:
• It transmits up to 512 in/512 out, for a total 1024
channels (in theory) of audio over a GbE network.
(The QL series features QL5: 64 in/64 out, QL1: 32
in/32 out with a 24/32-bit resolution.)
• Dante-enabled devices will automatically configure
their network interfaces and find each other on the
network. You can label Dante devices and their audio
channels with descriptive names that make sense to
you.
• Dante uses high accuracy network synchronization
standards to achieve sample-accurate playback with
extremely low latency and jitter. Five types of latency
are offered by the QL series: 0.25 msec, 0.5 msec, 1.0
msec, 2.0 msec, and 5.0 msec.
• A primary circuit and a secondary circuit provide
redundancy in the event of a problem.
• Connecting a Dante-enabled device to a computer
using an Ethernet connection enables you to directly
input or output audio signals without using any audio
interface devices.
• Audio can be transferred over distances up to 100
meters* between devices using CAT5e network
cables.
* Maximum practical distance may vary according to
the cable used.

NOTE
Please do not use the EEE function (*) of network switches
in a Dante network.
Although power management should be negotiated
automatically in switches that support EEE, some switches
do not perform the negotiation properly. This may cause
EEE to be enabled in Dante networks when it is not
appropriate, resulting in poor synchronization performance
and occasional dropouts.
Therefore we strongly recommend that:
• If you use managed switches, ensure that they allow
EEE to be disabled. Make sure that EEE is disabled on
all ports used for real-time Dante traffic.
• If you use unmanaged switches, make sure to not use
network switches that support the EEE function, since
EEE operation cannot be disabled in these switches.
* EEE (Energy Efficient Ethernet) is a technology that
reduces switch power consumption during periods of
low network traffic. It is also known as Green Ethernet
and IEEE802.3az.

About Dante Controller
Dante Controller is a software application that allows
configuration and audio routing of Dante networks. Use
this application if you wish to set up complicated signal
routings on a Dante network. More information is posted

Connecting to I/O devices
This section explains how to connect the QL series to I/O
devices (such as Rio3224-D) in a daisy chain network
and in a star network (redundant network). Before
connecting I/O devices, first perform "Setting up the
Dante network" (see page 34) and then turn off the
power to the QL series console.
Daisy chain network
A daisy chain is a wiring scheme in which multiple
devices are connected together in sequence. With this
method, networking is simple and requires no network
switches. This connection method is suitable for a
simple system with a small number of devices.
However, if a large number of devices are connected in
this way, the latency value must be increased. Also, if a
connection is broken in a daisy chain network, the signal
flow is interrupted at that point and no signal will be
transferred beyond that point.
