SPN Mixers
Introduction
The ASPEN digital matrix provides a maximum of 48
total outputs, but there is no limit to the number of inputs that can be added to a system by stacking multiple
units. Input only units deliver outputs to the digital bus,
so they are always used with a host mixer or conference unit to provide physical audio outputs.
ASPEN Series mixers are built around two “building
block” board assemblies. One is an 8 in/12 out mixer,
and the other is a 16 channel input only design. These
two building blocks are combined in various configurations to create various processor models:
• SPN8128input,12outputmixer,1RU
• SPN161216input,12outputmixer,2RU
• SPN162416input,24outputmixer,2RU
• SPN241224input,12outputmixer,2RU
Input only processor models include:
• SPN16i16channels,1RU
• SPN32i32channels,2RU
Other processor models include:
• SPNConferenceteleconferenceInterface,1RU
• SPNDNTDantenetworkinterface,1RU*
All models fully support the 48 outputs provided by the
digital matrix, regardless of how many physical outputs
are present on the rear panel. Any physical output can
deliver the signal from any output in the matrix.
Every input includes a dynamic noise reduction filter to
enhance dynamic signals and suppress steady state
noise. This unique algorithm is a single ended, frequency selective process that significantly reduces noise
from one or multiple sources.
When multiple units are stacked, Master and Slave
units are automatically detected and configured. All
data and audio from the Slave units in the system is
gathered in the Master, so a single connection between
a computer and the Master allows access to all units in
the stack. The throughput latency of all audio inputs in a
stack is automatically synchronized to maintain absolute signal phase at the audio outputs.
Quick Start Essential
Settings
Install the ASPEN Software before connecting
the processor to the computer USB port.
Wiring and Cable Connections
All inputs, outputs and control devices must be securely
connected following the pinouts and polarity shown on
pages 7 thru 9.
Interconnect Multiple Units
When multiple units are used, interconnect them via the
ASPEN ports on the rear panels. (see page 9)
Critical Settings for Mixer Models
Several settings must be made before the processor will
pass signals correctly:
• Inputlevelsmustbeset
• Crosspointsmustbedened
• Outputlevelsmustbeset
The settings can be made using the computer interface
or with the LCD. (see pages 10 and 16)
Special Settings for SPN Conference
If the sound system includes an SPN Conference processor, two of the final mixes must be used to generate
the input signals for the AEC (acoustic echo canceller)
and another mix must be routed to the telephone send
connection. Details for this critical setting are included
in the Installation Guide for the SPN Conference.
Signal Processing
Audio quality is significantly improved by using the various signal processing functions included in all channels.
There is no “gas gauge” and no limitation of DSP resources regardless of how many processes and stages
are enabled.
Every input channel includes settings for:
• Delay
• Noisereductionlter
• Equalization
• ADFE(autodigitalfeedbackeliminator)
• Compressor
Every output channel includes settings for:
• Delay
• Equalization
• Compressor
• Limiter

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.
Source

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.

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
such as the SPN1624, 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.

Installation and Startup Guide
Creating an ASPEN
Installer Disk
If you do not have the disk supplied with the processor, go to either of the following sites and download the
ASPEN Installation Disk .iso file.
http://www.lectrosonics.com/aspensupport/
Link from the home page: http://www.lectrosonics.com
Save the file to your local drive in a familiar location.
Open a disk copier utility such as Roxio Classic and
select the operation to Burn from a Disk Image File.
NOTE: The .iso file cannot be simply copied to the
disk. The disk recording utility must run a process
that creates a disk from a stored image file.
The .iso file format is recognized by almost any disk
creation software.
Firmware Update
Procedure
1) Install ASPEN software. See the next page for an
example of the installation procedure.
2) Launch the software. After the panel opens, click on
File > Update. The Update Wizard screen will open
to confirm that the software is ready for a firmware
update, with instructions on connecting and configuring the processor.
3) On the processor, hold the recessed pushbutton
switch in with a pen or paper clip and turn on the
power to the processor. The unit will boot into the
Firmware Update... mode and the white Alert LED
on the processor front panel will glow.

Update Wizard.
5) When prompted, use the “Browse” button to point at
the firmware update file and click Next to continue.

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.
Installation and Startup Guide
Click Next to proceed.
The End User License Agreement is presented.
Note: If AutoRun is not enabled then use Start->Run to
run “autoRun.exe” on the drive holding the ASPEN Install Disk. For example, if the CD-ROM drive is drive E:
then run “E:\autoRun.exe” to open the ASPEN Software
CD utility.
Click on the appropriate driver for your system:
• InstallUSBDrivers(32-bit)
• InstallUSBDrivers(64-bit)
The ASPEN Device Installer opens.
Accept, then click Next to proceed. The drivers are
installed from the CD.
When installation is complete, the Driver Name and
Status are displayed. Click Finish to close the Device
Installer.
Rio Rancho, NM
Click Close to finish. You may now connect to the ASPEN device via USB.

Stacking Multiple Units
If Slave units are not powered up when the Master unit
boots up, the Slave may not be detected for several
minutes. It is good practice to turn all units on simultaneously or turn on Slave units before turning on the
Master unit.
The available processors will appear in a “stack” on the
left side of the control panel. The Master unit will appear
at the top of the stack, with Slave units below it appearing in the order that they are connected with the cable
connections to the ASPEN port jacks.
List of connected units
Installation and Startup Guide
Refer to the cabling diagram for the ASPEN ports in the
section entitled Hardware Installation.
Refer to the Help Files
Once the processors are installed, configured and communicating with a computer system, refer to the Help
files in the software GUI for additional information regarding the available settings, adjustments and control.

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.
Therearenoadjustmentsinsidethatwillmakeamalfunctioningunitstartworking.
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.
