Radio frequency interference - Class A device
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Electric fields
Caution:
In accordance with Part 15 of the FCC Rules & Regulations, “… changes or
modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.”
Should this product be used in an electromagnetic field that is amplitude modulated by
an audio frequency signal (20Hz to 20kHz), the signal to noise ratio may be degraded.
Degradation of up to 60dB at a frequency corresponding to the modulation signal may
be experienced under extreme conditions (3V/m, 90% modulation).

About the DN965X units
The DN965X units provide bi-directional sample rate conversion of 24-bit resolution
digital audio between two clock domains, all in a standard 1U high 19” rack mount
chassis.
Front and rear panels of the DN9650 Network Bridge
The DN9650 has an AES50 and a network clock domain, provided by a three-port
AES50 digital audio interface and a third party network module interface, whereas both
clock domains of the DN9652 are of the network type and are provided by two, third
party network module interfaces.
Supported network modules are designed and manufactured by Lab X Technologies and
Audinate Pty Ltd. and conform to Cirrus Logic Inc. CM-1/CM-2 interface to support
protocols, which include MADI, Audinate Dante and Aviom A-Net.

Chapter 2: Overview
Front and rear panels of the DN9652 Network Bridge
Since the network clock domains (A and B) contain digital audio, an intermediate
asynchronous sample rate converter (ASRC) effectively resamples the audio as it
1
passes between them, while obeying Nyquist sampling theory . The ASRC has a bypass
option for when both domains are locked to the same sample clock; this has the facility
to select one of the clock domains as a master, which allows one to be synchronously
clocked from the other to minimise latency.
• AES50 clock domain Supports either internal or external synchronisation. The
DN9650 uses its on-board clock oscillator for internal synchronisation. For external
synchronisation, the incoming clock is connected to one of the AES50 ports.
Additionally, the AES50 clock domain has the option of slaving to the network clock
domain, word clock and video black burst if the SRC is bypassed.
• Network clock domain Supports clock synchronisation to the incoming clock via
a third party network module, word clock in or video black burst (supporting
PAL/NTSC formats) interfaces. Additionally (DN9650 only), the network clock
domain has the option of slaving to the AES50 clock domain.
Supported third party multi-channel digital audio interfaces are as follows:
• LabX MADI V1.14
• Audinate Dante
• Aviom a-Net
• Ethersound
• It is intended that more third party protocols will be supported
The DN965X has an internal Linux web server running a platform-independent
HTML-based interface that allows unit configuration via a computer (with up-to-date
browser), which is connected to the Ethernet port on the rear panel of the unit.
Supported platforms are: PCs (Windows); Apple Macs; and Linux-based PCs.
The units are capable of operating from a 100 to 240V ±10%, 50 to 60Hz AC power
source.
Key features
The DN965X has the following key features:
• 1U high, 19” rackmount unit.
• Able to interface between AES50 and third party multi-channel audio networks
(DN9650 only) or dual networks (DN9652 only).
1. The Nyquist sampling theory defines the process of sampling audio within a digital system.

Updating the unit’s host software
The upgrade procedure involves transferring a number of files individually to the
DN965X unit. The files are supplied in a single TAR file. Before you can begin the
upgrade these files must be ‘unzipped’ to a location that is easily accessible from your
computer.
The TAR file will contain all of the files required to update any type of unit, as listed in
the following table, which also shows the recommended order of upload. Although this
order is not critical, it is important that you upload the 9650apps.img file last, as this
file triggers a reboot of the DN965X unit.

Chapter 6: Operation
Although there are no operating procedures associated with the DN965X, this chapter
shows you how to create a MADI split.
Using a MADI module as a MADI split
One of the features of the MADI card is that it allows you to create a MADI split. This is
because the MADI card has both optical and co-axial connections, which can both be
enabled simultaneously in the software (see “Setting up a network module” on
on both remote systems. However, this configuration has some very real limitations as

Fibre optic cables
Coaxial cable
Rx
Tx
MADI device (slave)
Tx
Typical example of a DN9650/DN9652 connected in a MADI split configuration
>> To configure the MADI module as a MADI split
• Set the unit MADI card as clock source (for example, choose master, onboard
oscillator, WCLK etc.).
• One format (for example, optical) connected in a loop (Tx and Rx) as usual to a
remote system (MADI slave).
• The other format (co-axial in this case) connected by just the Tx connection on the
module to another remote system (also MADI slave).
Limitations
The limitations of using the MADI module as a MADI split are as follows:
• Incoming audio to DN965x unit is only available from one remote MADI system.
• There is no clock domain separation between the two remote systems.
• If the remote system with the bi-directional link goes down or the link is
disconnected the other remote system loses its audio feed.
• Errors at the other end of the uni-directional link cannot be detected.

Checking/replacing the mains fuse
Checking/replacing the mains fuse
The equipment must be independently isolated from the mains voltage supply
before any attempt is made to change the protective fuse. The fuse and its
cover must always be replaced before the equipment is reconnected to the
mains voltage supply.
Only use the correct replacement type when changing the fuse. Fuse specification is
printed on the rear cover.
prise out the fuse from the furthest compartment (the nearest compartment is for a
spare fuse); a small, flat-bladed screwdriver may be useful for this.
Insert a new fuse in the rear fuse compartment, and close the drawer.
After replacing a fuse, check that the unit is working properly.
Always ensure that there is a spare fuse available.
Special accessories
To comply with part 15 of the FCC Rules, any special accessories (that is, items that
cannot be readily obtained from multiple retail outlets) supplied with this equipment
must be used with this equipment; do not use any alternatives, as they may not fulfil
the RF requirement.
Optional equipment
Unless advised otherwise, optional equipment must only be installed by service
personnel and in accordance with the appropriate assembly and usage regulations.
Equipment disposal
When this equipment has come to the end of its useful life, its disposal may come under
the DIRECTIVE 2002/96/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of
27 January 2003 on waste electrical and electronic equipment (WEEE).
Hazardous substances in WEEE contaminate water, soil and air and ultimately put at
risk our environment and health. The directive aims to minimize the impacts of WEEE
on the environment during their life times and when they become waste.
The WEEE directive addresses the disposal of products when they have reached the end
of their life and contributes to the reduction of wasteful consumption of natural
resources. This will help to reduce pollution, and protect the environment and
ourselves.
If this equipment carries a ‘crossed-out wheelie bin’ (shown left), please
do not dispose of WEEE as unsorted municipal waste but collect and
dispose of in accordance with local WEEE legislation. The horizontal bar
underneath indicates that the product was placed on the EU market after
13th August 2005.
