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 telep-
resence 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 mi-
crophones (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 pro-
portional 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 de-
sign allows simultaneous, multi-point third party control.
A two channel power amplifier is included for loud-
speakers 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 imple-
mented with a late generation component that provides
exceptional efficiency, low heat and excellent audio
performance. The amplifier cannot be damaged by wir-
ing errors.

Power Inlet
The switching power supply will operate with line volt-
ages 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 con-
nectors. Processors are normally installed with the Mas-
ter 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 program-
mable input and control a variety of other parameters.
ASPEN Bus Data/Audio Ports
These RJ-45 jacks carry the audio signals and con-
trol 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.

Audio Inputs – Unbalanced
Unbalanced audio sources include items such as
consumer VCR’s, DVD players, etc., which can be con-
nected 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.

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 appropri-
ate 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 con-
ductor plus ground/shield.
Audio Connectors
The analog audio inputs and outputs are connected
through 5 pin de-pluggable connectors. Strip the insula-
tion back 1/8 to 3/16” but do not tin (apply solder to)
the leads. Insert the wire into a de-pluggable connec-
tor, leaving less than 1 mm of bare wire exposed, then
tighten the retaining screw.
Caution: Do not overtighten the screws.
5-pin depluggable
connector
Do not leave more than
1 mm of exposed wire
beyond the connector.

Retaining Screw
(Do not overtighten)
Note the labeling on the rear panel for the positive and
negative leads. Ground is shared between two connec-
tions (the center pin).
Note: ASPEN processors do not have a “pin 1
problem.” Inputs and outputs are true differential
connections.

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 pro-
grammable 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.
Audio Outputs
The line outputs are a balanced differential configura-
tion which can drive balanced or unbalanced inputs on
other audio equipment with the wiring shown here.
Balanced output to a balanced input is a straightforward
“pin to pin” configuration.

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 con-
nector. 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 bi-
directional, handling data and audio signal forward and
back propagation through a single cable connection.

If a unit is connected to another unit above it through
the upper connector, it is automatically configured as

Master.
