DN9650
AES50 Network Bridge Format Converter with up to 64 Bidirectional Channels and Asynchronous Sample Rate Conversion
DN9650 provides a multichannel interface between AES50 networks and third party digital audio networks and point-to-point interfaces. The AES50 and third party interfaces operate in separate clock domains and are connected by a bidirectional asynchronous sample rate converter (ASRC). This unique KLARK TEKNIK technology allows the interfacing of up to 64 bidirectional channels between the two independently clocked domains, which can also operate at different sample rates. Currently supporting MADI and Audinate Dante via the KLARK TEKNIK KT-MADI And KT-DANTE64 network modules, DN9650 is future-proofed in the evolving world of digital audio networking technology by being able to support new and emerging protocols via its industry-standard expansion slot, which is compatible with the Cirrus CM-1 format.
The DN9650 allows MIDAS PRO Series digital consoles and MIDAS digital I/O hardware and other 96 kHz-enabled AES50 devices to interface to multichannel MADI and Dante connections, simply and reliably.
Digital Audio Networking
SuperMAC (AES50-Compliant) digital audio networking technology from KLARK TEKNIK simultaneously provides high channel counts, ultra low and deterministic latencies, sample-synchronous and phase-aligned networked clock distribution, error detection and correction, network redundancy, and ease of deployment and use ? to meet the demanding requirements of live concert touring.
DN9650 is compatible with all MIDAS digital consoles, audio system engines, digital I/O units, as well as with any other AES50-equipped devices.
Asynchronous Sample Rate Converter
The multichannel bidirectional Asynchronous Sample Rate Converter (ASRC) allows the AES50 and third party domains to function independently, however in instances where the two networks need to be synchronised, the ASRC features a bypass facility so that the third party network domain can be directly clocked from the AES50 domain.
Additionally, when the two domains are operating independently, a clock failure or loss of synchronisation in one domain will not necessarily affect the operation of the other. Very often in dual-redundant systems it is desirable to propagate a clock failure in one domain across to the other, so that the failure can be recognised and switchover to the redundant network can be initiated. DN9650 features a user-configurable bidirectional output clock inhibit feature that will stop the output clock if the incoming clock synchronisation fails.
Flexible Synchronisation
DN9650 supports 24 bit audio operation at 48 kHz and 96 kHz independently in both the AES50 domain and the third party network domain. If the on-board oscillator (AES50 internal clock) is selected, then all three AES50 ports can either be set to globally operate at either 48 kHz or 96 kHz. If AES50 external clock is selected as the clock source, then each AES50 port can be set to provide 24 bidirectional channels at either 48 kHz or 96 kHz sample rate on an individual basis.
Word clock input and output connections plus a black burst horizontal video sync input are provided on BNC connectors, with the latter supporting PAL, SECAM and NTSC formats in standard defi nition and high definition 720P, 1080P and 1080i formats. The word clock output can be derived from the AES50 clock domain, the third party network clock domain or the word clock input.
DN9650 features a precision ?AES Grade 1? reference temperature-compensated clock oscillator with 1 part-per-million (ppm) stability which is used as the AES50 internal clock source. This highly accurate clock source can be used as the reference clock for digital audio systems, providing a very defi ned sound image free of jitter and other digital clocking error artefacts.
The AES50 domain can be synchronised to the incoming AES50 external clock signal, the AES50 internal clock, the word clock input or the video black burst video sync input.
The third party network domain can be synchronised to the external network clock (with or without word clock synchronisation), the network module onboard clock, the word clock input or the black burst video sync input, as well as optionally slaving to the AES50 clock domain if the ASRC is bypassed.
Internal Web Server
DN9650 features an on-board web server that allows platform-independent configuration using a web browser application. The need for separate control applications and support for multiple operating system versions is eliminated with this approach, which allows simple user selection of network module and DN9650 settings, including AES50 and third party network domain sample rates, clock synchronisation for both domains and the ASRC bypass and bidirectional output clock inhibit functions.
Front Panel Indication
DN9650 features status LED indicators for AES50 and network synchronisation, Ethernet control port activity and the ASRC bypass and bidirectional output clock inhibit functions on the front panel for ?at a glance? status display, even at wide distances and viewing angles. An alphanumeric LCD display allows individual units to be labelled, essential in large network systems where multiple DN9650 units are in use.
Built for the Road
Featuring a rugged steel 1U rackmount enclosure, the DN9650 is designed for the rigours of live concert touring. Premium Neutrik etherCON* and BNC connectors are used to ensure reliable network and clock connections, night after night.
Auto-ranging universal switch-mode power supply
DN9650 features a universal power supply, which is auto-voltage sensing for use on a worldwide basis.

Octave: The difference between two frequencies where one is twice the other. For example, 200 Hz is an octave higher than 100 Hz. 400 Hz is one octave higher than 200 Hz.
Optical Digital Cable: Fiber optic cable that transfers digital audio signals as light pulses.
Outcue/Outq/Out-Point: These words all refer to the final few seconds of audio signifying the conclusion of the production.
Package: A completed and fully edited audio piece.
Passive: Not active. A passive crossover uses no external power and results in insertion loss. A passive speaker is one without internal amplification.
Phase: Time relationship between signals it’s all relative.
Power Output: A measure, usually in watts, of how much energy is modulated by a component.
Preamplifier: A control and switching component that may include equalization functions. The preamp comes in the signal chain before the amplifiers.
Pre Outs: Connectors that provide a line-level output of the internal preamp or surround processor.
Pre Outs/Main Ins: Connectors on a receiver that provide an interruptible signal loop between the output of the internal preamp or surround processor portion of the receiver and the input of the amplifier portion of the receiver.
Pre/Pro: A combination preamp and surround processor.
Processors: Anything that processes an incoming signal in some way. Surround processors, for example, can decode a Dolby Digital signal to send to an amp so you can hear it.
Pulse Code Modulation: (PCM) a way to convert sound or analog information to binary information (0s and 1s) by taking samples of the sound and record the resulting number as binary information. Used on all CDs, DVD-Audio, and just about every other digital audio format. It can sometimes be found on DVD-Video.
Q-and-A: Question and answer session.
Receiver: Any component that receives, or tunes, broadcast signals, be it NTSC, HDTV, DBS, or AM/FM radio. Typically refers to the single component that includes a preamp, surround processor, multichannel amplifier, and AM/FM tuner.
Reverberation: The reflections of sound within a closed space.
RF: Radio Frequency. Television signals are modulated onto RF signals and are then demodulated by your television’s tuner. VCRs and DBS receivers often include channel 3 or 4 modulators, allowing the output signal to be tuned by the television on those channels. Also, laser discs used an RF signal for modulating Dolby Digital 5.1 soundtracks on some movies. This requires an RF demodulator (usually referred to as an AC3-RF demodulator) before or in the surround processor to decode the signal.
RMS: Root Mean Square or the square root of the arithmetic mean (average) of the square’s set of values. A reasonably accurate method of describing an amplifier`s power output.
SACD: Super Audio CD. Enhanced audio format with up to six channels of high-resolution audio encoded using DSD. Requires an SACD player. Multichannel also requires a controller with six-channel analog or proprietary digital inputs for full playback.
Sampling Frequency: How often a digital sample is taken of an analog wave. The more samples taken, the more accurate the recording will be. You need to sample at a minimum of twice the highest frequency you want to capture. For example, the 44.1-kilohertz sampling rate of a CD cannot record sounds higher than 22.05 kilohertz.
Scener: A radio report in which the announcer is recorded at the same time and place as the background sound of an event.
Sensitivity: A measurement (in dB) of the sound-pressure level over a specified frequency range created by a speaker driven by 1 watt (2.83V at 8 ohms) of power with a microphone placed 1 meter away.
Signal-to-Noise Ratio: A comparison of the signal level relative to the noise level. Larger numbers are better.
