DN9680 8-port AES50 Extender
1. Introduction
Welcome!
Thank you for purchasing a KLARK TEKNIK DN9680 8-port AES50 Extender.
The DN9680 is an 8-port AES50 extender designed to take up to eight AES50
connections, convert them to HyperMAC for transport over distances of up to one
kilometre and then convert them back to AES50 on a port-for-port basis.
The DN9680, which is housed in a 1U, 19" rack mount unit, transports up to
192 digital audio signals at 96kHz, bi-directionally over distances of up to 1km
on a single mode 1300nm laser. The unit includes simple port-to-port routing
and optional internal clock generation. The AES50 input format is suitable for
products in the Midas digital console range and future AES50-enabled Behringer
digital consoles.
Two DN9680s are required in a typical system set-up, each one being congured
via a simple utility that is based on hypertext transfer protocol (http) and
accessed through an Ethernet control port.
The DN9680 was conceived by KLARK TEKNIK to oer audio professionals high
performance audio equipment, designed to provide no-compromise sonic
quality with a feature set that oers all essential facilities and functions. It
represents the very best of British design and engineering combined with
contemporary, ecient manufacturing methods, and will give you many years of
reliableservice.
So, to obtain the best results with a minimum of eort, please read this manual
and, nally, enjoy your KLARK TEKNIK DN9680 8-port AES50 Extender!
1.1 Key features
The DN9680 has the following key features:
• 8 x AES50 etherCON® input ports.
• Each AES50 port carries 24 channels of 96kHz digital audio plus control data.
• AES50 is converted to HyperMAC for transport over a snake to another
DN9680, which converts signals back to AES50 on port-for-port basis.
• Option of optical bre (up to 1km) or copper snake (up to 100m) via an
opticalCON® port or etherCON port, respectively.
• Ethernet control port for unit conguration (IP address, sample rate, clock
options, etc.) via on-board web-based application.
• LCD display.
• Unit is transparent when connected to console (cannot be detected), so that
any device connected at an AES50 port will have its signalling information
(port info., redundancy info., diagnostics, discovery, etc.) mirrored at the
other DN9680.
• 96kHz sample rate.
• Three clock options: internal; external AES50; and external snake.
• Mains input is a switch mode power supply (SMPS) with on/o switch and
fuse drawer for easy fuse replacement.
• Internal fan.
• Reset button for resetting the unit to its factory default condition.

2. Getting Started
This section shows you how to unpack, install, connect up, power up and
congure the DN9680 unit.
◊ This equipment is supplied by a mains voltage that can cause electric shock
injury.
◊ This equipment is supplied with a bre optic connection system. Beware of
laser radiation. Do not stare into the beam!
◊ Before installing, setting up or operating this equipment, make sure that you
have read and fully understand all of this section and the “Important safety
instructions” at the front of this manual.
2.1 Unpacking
Carefully unpack your DN9680 equipment package.
Then, inspect the DN9680 unit carefully for any signs of damage that may have
occurred during transit and notify the courier immediately if you discover any.
Check the contents of your DN9680 equipment package. If there are any parts
missing, incorrect or faulty, please contact your local distributor or Midas at the
address at the front of this manual.
Please retain the original packing in case you should need to return the
equipment to the manufacturer or supplier, or transport or ship the unit later.
2.2 Installation
Before installing and operating this equipment, make sure it is correctly
connected to the protective earth conductor of the mains voltage supply socket
outlet through the mains lead.
Do not install the equipment in places of poor ventilation.
Do not install this equipment in a location subjected to excessive heat,
dustormechanical vibration. Allow for adequate ventilation around
the equipment, making sure that its fans and vents are not obstructed.
Wheneverpossible, keepthe equipment out of direct sunlight.
Mount in rack only.
Power
◊ The supply cord must be unplugged to ensure complete de-energisation of
the unit.
The internal power supply is of the switch mode type that automatically senses
the incoming mains voltage and will work where the nominal voltage is in the
range 110V AC to 230V AC.
A mains inlet is provided on the rear panel. The correct lead for connection in
the area to which the unit was shipped is supplied with the unit. The equipment
should only be plugged into the mains outlet using the supplied lead.
Handling the equipment
When lifting or moving the equipment, always take its size and weight into
consideration.
Completely isolate the equipment electrically and disconnect all cables from the
equipment before moving it.
Do not insert your ngers or hands in any gaps or openings on the equipment,
forexample, vents.
Electric elds
In accordance with Part 15 of the FCC Rules & Regulations, “… changes or
modications 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 eld that is amplitude
modulated by an audio frequency signal (20 Hz to 20 kHz), 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 (3V/m,90% modulation).
2.3 Connecting up
Connect up the units as required:
• AES50 cables from AES50-equipped device (for example, console) to rst
DN9680.
• Optical/copper snake from rst DN9680 to second DN9680.
• AES50 from second DN9680 to other AES50-equipped device (for example,
I/O unit).
• Mains power IEC connectors to both DN9680s.
2.4 Powering the unit on/o
Swith on the mains on/o switch of both DN9680s (rear panel). The blue roundel
on the front panel of the unit should illuminate to show that power is on.
2.5 Conguration
Congure the DN9680s to suit the system parameters (for example, clock source,
sample rate frequency, etc.). For details, see "6. Conguring The DN9680 " on
page 8.
