SPNTWB
Introduction
The SPNTWB combines the circuit board assemblies from the SPN812 and SPNCWB in a 2RU chassis to provide a complete, stand-alone component for telepresence and audio conferencing systems. The unit can also be used with additional ASPEN processors to add additional inputs and outputs. Setup and adjustments can be made using the control panel software or the front panel LCD interface. Inputs and outputs appearing on the LCD have been consolidated into logical groups to simplify navigation.
The far end audio signals in a conference participate in the automatic mixing algorithm in same manner as local microphones connected to the processor. Three sites connected via two codecs and a telephone line can be bridged into a single conference with the local site.
The ASPEN acoustic echo canceller was developed to address the need for a single acoustic echo canceller that could handle the challenges of multi-site bridging and an unlimited number of microphones. The AEC converges very quickly, then continues to increase the cancellation depth at every opportunity as a conference continues. Cancellation depth will increase even with brief signal peaks from the far end, and convergence will never be lost with any type of signal or in double talk situations.
Signals from the far ends of the conference are routed to the local sound system as well as serving as the reference signal for the AEC. Audio from the local microphones (which includes far end audio from the local loudspeakers) is routed to the AEC via a second final mix. Far end audio present in the microphone signal mix is cancelled, and the output of the AEC is routed back to the far ends through the matrix.
The AEC in combination with the patented gain proportional mixing algorithm* provides outstanding audio quality without echo heard at the far ends.
An ethernet port is provided for setup and control via standard network connections, and an RS-232 port is provided for use with remote control systems. The design allows simultaneous, multi-point third party control.
A two channel power amplifier is included for loudspeakers in the local sound system. The power amplifier is driven by final mix outputs from the matrix and has a full set of signal processing, including parametric EQ, compressor and limiter. Class-D amplification is implemented with a late generation component that provides exceptional efficiency, low heat and excellent audio performance. The amplifier cannot be damaged by wiring errors.

Power Inlet
The switching power supply will operate with line voltages between 100 and 240 VAC. The inlet socket is a standard 3-pin C14 type that accepts any cordset with a
C13 connector.
Cooling Fan
The microprocessor monitors the internal temperature of the processor and controls the variable speed fan as needed. Operating temperature is very well regulated.
RS-232 and Ethernet Ports
Each host assembly provides RS-232 and Ethernet ports for communication with the microprocessor. The ports can be utilized simultaneously for monitoring, setup and control.
ASPEN Ports
This gigabit bus transports audio and data from one board to the next through CAT-6 cabling and RJ-45 connectors. Processors are normally installed with the Master unit on top and Slave units below it. The cabling is then connected from the uppermost jack on one board to the lowermost jack on the unit just above it. See page
9 for more information.
Balanced Mic/Line Inputs
Every mic/line input is a balanced, differential type with adjustable gain from -10 to +60 dB. Connectors are a standard 5-pin Phoenix depluggable type with adjacent channels sharing a common ground.
Balanced Outputs
All outputs are a balanced, differential type. Channels 1 through 8 on each board are nominal line level outputs with gain adjustment from -60 to +20 dB. Channels 9 through 12 on each board are also line level outputs with switchable attenuation of -20 and -40 dBu nominal levels (mic level), with gain adjustment from OFF to +20 dB.
Programmable Input and Output Ports
Programmable inputs and outputs used to control levels, settings, indicate the current state of a programmable input and control a variety of other parameters.
ASPEN Bus Data/Audio Ports
These RJ-45 jacks carry the audio signals and control data between each system board as well as units stacked together.
Remote Control
These RJ-45 jacks provide interfaces for RCWTH4 remote control units. Each jack is assignable to CODEC
1 or 2, or to the telephone line.
Conferencing Inputs and Outputs (Codecs)
Analog audio input and output connectors for the Codec ports.
Telephone Set/Line
RJ11 jacks for connecting a standard telephone line and a single-line telephone set.
Power Amp Outputs
The amplifier is designed to run continuously (idle or with a load) without heat buildup, making it ideal for permanent installations where prolonged operation is required.

Hardware Installation
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.
Cables
It is recommended to use lacing bars for cable strain relief when mounting in a rack. Use only professional audio cable with proper shielding – typically, two conductor plus ground/shield.
Audio Connectors
The analog audio inputs and outputs are connected through 5 pin de-pluggable connectors. Strip the insulation back 1/8 to 3/16” but do not tin (apply solder to) the leads. Insert the wire into a de-pluggable connector, leaving less than 1 mm of bare wire exposed, then tighten the retaining screw.
Caution: Do not overtighten the screws.
Retaining Screw

Programmable Outputs
Programmable outputs are used for several purposes:
• indicate the current state of a programmable input
• monitor activity on telephone or codec interfaces
• 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.

Cabling Of Stacked Units
In a stacked configuration, ASPEN processors must be interconnected as shown here. 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 below it. In this manner, all Slave units have access to all inputs on any unit in the stack.
Each circuit board has an upper and a lower CAT-5 connector. Since there are two circuit boards in a 2RU unit, the circuit boards are connected in the same manner as if they were in separate chassis. The ASPEN bus is bidirectional, handling data and audio signal forward and back propagation through a single cable connection.

A simple interface is provided to communicate directly with the processor through a network using the HTTP port and a standard browser. This interface provides access to the processor in the same manner as the
Command Terminal interface in the software.
Launch your browser and enter the IP addresses assigned to the processor in the top window.
When the processor is connected a summary screen will appear to verify the connection. Click on the link to enter the dialogue screen.
Connect the processor into the network and cycle the power. The processor will boot up and the DHCP server will assign an IP address. The address can be viewed in the
Network Settings display.
IP address will appear here.

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 “doubleboxed” for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
