Overview
Installation and Quick Start Guide
What is Dante?
Audinate’s patent pending Dante™ technology is a flexible Internet Protocol (IP) and Ethernet based digital AV network technology that eliminates the many bulky cables needed to provide point-to-point wiring for analog AV installations.
With Dante, existing infrastructure can be used for high performance audio as well as for ordinary control, monitoring or business data traffic. Digital networks utilize standard IP over Ethernet offering high band­width capable of transporting hundreds of high quality channels over Gigabit Ethernet.
Set-up and configuring the system is made easy as well, saving enormous installation costs and long term cost of ownership on a digital network. The physical connecting point is irrelevant: audio signals can be made available anywhere and everywhere. Patching and routing now become logical functions configured in software, not via physical wired links
The Role of the SPNDNT Processor
The SPNDNT acts as a node on the Dante digital au­dio network, with 32 inputs and 32 outputs. SPNDNT outputs are mapped to Dante transmit channels. Dante receive channels are mapped to SPNDNT inputs, which can be routed to mix busses in the ASPEN mix matrix. All of the normal automatic mixing features are available in the SPNDNT mix matrix. Gain control and muting are available for the SPNDNT inputs (Dante receive channels) and outputs (Dante transmit chan­nels).
Switched and Redundant Modes
The rear panel Dante ports allow operation in a switched mode through a single network using either jack, or in a redundant mode through two separate networks using both jacks simultaneously. Redundancy is required in some applications where it is imperative that no audio is lost due to network problems, such as in courtroom recording. The secondary network dupli­cates real-time audio traffic. If the primary network fails for any reason, the secondary network’s audio contin­ues without losing even a single sample.
See page 15 and also refer to the help files and documentation provided by Audinate for more informa­tion regarding the setup for switched and redundant modes.

USB Driver Installation
The ASPEN USB drivers are installed from the ASPEN Installation Disk, which comes with each device, by running the ASPEN Device Installer. Normally this is done before connecting an ASPEN device to the PC for the first time, but it can be done afterwards if neces­sary. The driver installation only needs to be done once on each PC that will be connected to an ASPEN unit.
If an ASPEN device is connected to a PC without prior installation of the drivers from the ASPEN Installation Disk, manual installation is possible for Windows XP and Vista operating systems using the New Hardware Found wizard. In the case of Windows 7, there is no New Hardware Found wizard, so manual installation is a bit more involved. In any of these cases it’s not really necessary if you have the installation disk. Just cancel the New Hardware Found wizard (if open) and run the ASPEN Device Installer from the Installation Disk.
Installation with ASPEN Device Installer
Place the ASPEN Installation Disk into the CD-ROM drive. If “AutoRun” is enabled on that drive then the ASPEN Installation Disk utility will open. Click on Install ASPEN Software/USB Drivers.

Installing the chassis into a rack
Install the chassis so that the cooling fan vent is not blocked. Mount with 4 rack screws using the appropri­ate mounting holes. Use nylon washers to prevent damage to the front panel’s finish when tightening the mounting screws.
All ASPEN processors have internal switching power supplies that can tolerate voltages ranging from 100 to 240 VAC. Use an approved power cord with an IEC 60320 C13 connector.
Connecting the Master for the First Time
NOTE: Install ASPEN software before connecting the Master unit to a computer.
The computer operating system will automatically de­tect and configure a USB port for the Master unit when it is connected and turned on the first time. Wait for the screen message that advises that the new device has been configured and is ready for use.

RS-232 is a common interface with LCD touch panel control systems such as Crestron® and AMX®. The wiring diagram for DB-9 connectors is shown on the opposite page.
The ETHERNET port is used with ASPEN control panel software for setup, monitoring, control and diagnostics. It does not transport audio. IP addresses can be set up statically, or one can be assigned by a network server if DHCP is enabled in the software control panel.
ASPEN Ports connect multiple processors for data and signal flow. 2RU units have two internal circuit boards that must be connected with cables in the same man­ner as two separate processors.
The DANTE ports connect to network switches. Multiple SPNDNT processors can also be connected directly to each other through these ports.
Interconnect multiple ASPEN processors
with Dante Controller software
Cabling Of Stacked Units
NOTE: The SPNDNT must always be the Master at the top of the stack to synchronize the ASPEN system and network clocks.
The ASPEN bus is bidirectional, allowing data and audio to be propagated forward and backward through a single cable connection. Each Slave unit in a stack gathers data and audio signals from the unit below it, adds its own signals and passes the total on to the unit above it. At the top of the stack, the Master unit gathers all signals from below, adds its own and then sends the total back down the bus to all Slave units.
This architecture allows all Slave units to have access to the mixing data and audio in all 48 final mixes.
Each circuit board has an upper and a lower ASPEN bus connector. Since there are two circuit boards in a 2RU unit such as the SPN1624, the circuit boards are connected in the same manner as if they were each in a separate chassis.

This is the easiest connection point to run ASPEN control panel software until the network is configured and IP addresses have been established. Connect the computer to the Master unit in the ASPEN stack and launch the control panel software. The Master unit will appear on the screen, and the Slave units below it will then be accessible as well.

Programmable Inputs
Programmable inputs are provided to enable external control over a variety of parameters. Each input can respond to a contact closure, a DC voltage source, or the variable voltage output from a potentiometer. The following illustrates common connections to the programmable input pins.
Programmable Outputs
Programmable outputs are used for several purposes:
• indicatethecurrentstateofaprogrammableinput
• monitoractivityonaudioinputchannels
• monitoractivepresetchanges
Each programmable output is the electrical equivalent of a contact closure to ground. When a programmable output is “active” it conducts current to ground. When the programmable output is “inactive,” no current flows to ground. The maximum usable voltage for the pro­grammable outputs is 40 V and they will safely conduct up to 100 mA DC continuous.
Both LEDs and 5V relay coils can be powered by the +5 V DC pins on the programmable input connector, as long as the maximum combined current for all LEDS and relay coils does not exceed 100 mA.

Using Switched and Redundant Modes
NOTE: See page 11 for instructions on selecting the mode using Dante Controller software.
Set processors to the Switched mode for setup.
In the Switched mode, the Primary and Sec- ondary ports can be connected in any combi­nation since there is an ethernet switch in the hardware.
In the Redundant mode, the Primary ports on all processors must be connected to the first net­work and the Secondary ports on all processors must be connected to the second network.
After all connections and settings are completed and the system is passing audio through the net­work, connect the second network and set the processors to the Redundant mode.

ASPEN Digital Processor
System Setup Examples
Basic Configuration
X = INPUT O = OUTPUT
This example illustrates the basic signal routing be­tween two ASPEN subsystems connected via a Dante network. This setup creates a “full-duplex” connection where each ASPEN subsystem transmits and receives signals simultaneously as might be used to conduct conferencing between two meeting rooms. In this ex­ample, no local sound reinforcement is in use.
The success of this setup could be limited by loud­speaker/microphone acoustical coupling in the sound systems in each room. If the level of the sound from the loudspeakers arriving at each microphone is not far below the loudness of the talker, an echo will be heard at the far end (opposite ASPEN system). With careful placement of loudspeakers and microphones, and the use of mix-minus zoning, this type of system can be used.
NOTE: See the next example regarding the use of the AEC (acoustic echo canceller) on network connections.
In the ASPEN subsystem on the left, the blue lines indicate inputs with the signal path starting at the microphones. The audio is routed to Mix 1 and Mix 2 in the ASPEN matrix, which are then assigned to Dante transmit channels 1 and 2 (labeled Out 1 and Out 2) in the SPNDNT processor.
In the ASPEN subsystem on the right, Dante receive channels 1 and 2 are assigned to Mix 1 and Mix 2 in the ASPEN matrix by the SPNDNT processor. These two mixes are then selected as the signal sources for outputs 1 and 2 of the mixer.
The reverse of this signal flow (in red) from the ASPEN system on the right to the system on the left takes place through ASPEN Mixes 3 and 4, and Dante trans­mit channels 3 and 4.
Each ASPEN system is an independent sub-system, so the Mix numbers used in one system have no bear­ing on those used in any other ASPEN sub-system. The Mix numbers used here were chosen only for clar­ity in visualizing the signal paths.

ASPEN Digital Processor
Using the AEC on Network Connections
When the Trio or Conference processor is used in the ASPEN subsystem, the AEC (acoustic echo canceller) can be applied to the network connections to suppress echo caused by acoustical coupling between micro­phones and loudspeakers. In this example, a local sound reinforcement system is in place, which further increases the potential echo.

Route the inputs as follows:
• In1toMix1andMix5
• In2toMix2andMix5
In this example, Mixes 1 and 2 are routed to the local sound system in a mix-minus pattern. Mix 5 delivers the audio from the local microphones into the Dante network.

In this example, the processors in the subsystems all subscribe to receive audio from the other two subsys­tems on Dante transmit channels 1 and 2.
A system configuration like this would be an ideal solu­tion for multi-site Telepresence video conferencing by allowing a full-duplex, system wide audio signal flow.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equip­ment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the inter­connecting cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose con­nection, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require read­justment. There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a mod­est flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by e-mail or by phone. We need
to know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help
speed your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with
the proper packing materials. UPS or FEDEX is usually the best way to ship the units. Heavy units should be “double-boxed” for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
