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.

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.
Audio Inputs – Unbalanced
Unbalanced audio sources include items such as
consumer VCR’s, DVD players, etc., which can be connected with either two wire or three wire cables. The (+)
terminal of the source is connected to the (+) terminal
of the processor. The shield and (–) connections are
made as shown here.
Three wire cables should have the shield connected to
the (–) connector at the source end of the cable.

Programmable Outputs
Programmable outputs are used for several purposes:
• indicatethecurrentstateofaprogrammableinput
• monitoractivityontelephoneorcodecinterfaces
• monitoractivepresetchanges
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.

Wiring Diagram
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.

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.
