Quick Start Essential
Settings
IMPORTANT: Do not connect the processor to
a USB port until AFTER the software has been
installed.
Wiring and Cable Connections
All inputs and control devices must be connected follow-
ing 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:
• Input levels must be set
• Crosspoints must be defined
The settings are made using the computer interface.
Special Settings for SPN Conference
If the sound system includes an SPN Conference pro-
cessor, two of the final mixes must be used to generate
the input signals for the AEC (acoustic echo canceller).
Details for this critical setting are included in the Instal-
lation Guide for the SPN Conference processor.
Signal Processing
Audio quality is significantly improved by using the vari-
ous signal processing functions included in all channels.
All processes can be fully enabled without limitation
on DSP resources. There is no “gas gauge” limitation
regardless of how many processes and stages are
enabled.
Every input channel includes settings for:
• Delay
• Noise reduction filter
• Equalization
• ADFE (auto digital feedback eliminator)
• Compressor
Introduction
The SPN16i and SPN32i processors are used as a
Slaves in a stack of ASPEN processors. There are no
physical outputs on these “input only” processors. As
their descriptions imply, the only outputs are into the
system matrix that is common to all processors in the
stack. 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.
Multiple processors are interconnected via the ASPEN
bus, which operates at 1 Gbps to conduct data from the
lowermost Slave to the Master. All signals are gathered
in the Master and then returned to the lower Slaves via
the ASPEN bus.
When multiple units are stacked, Master and Slave
units are automatically detected and configured accord-
ing to the cabling between units. Since the data from
the Slave units in the system is gathered in the Master,
a single connection between a computer and the Mas-
ter allows access to the data from all units in the stack.
Audio propagates through the ASPEN bus in the same
manner as data. The throughput latency of all audio
inputs in a stack is automatically synchronized to main-
tain absolute signal phase at the audio outputs.
Any of the ASPEN mixer models and the conference
model can be used as the Master in the system:
• SPN812 8 input, 12 output mixer
• SPN1612 16 input, 12 output mixer
• SPN1624 16 input, 24 output mixer
• SPN2412 24 input, 12 output mixer
• SPNConf teleconference Interface

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 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.
5-pin depluggable
connector
Do not leave more than
1 mm of exposed wire
beyond the connector.
Do not apply
solder to leads
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 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 pro-
grammable input pins.

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.

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
such as the SPN1624, the circuit boards are connected
in the same manner as if they were in separate chas-
sis. The ASPEN bus is bidirectional, handling data and
audio signal forward and back propagation through a
single cable connection.

ASPEN PORT
The processors automatically configure themselves for
Master and Slave status as determined by the cabling.
If a unit is connected to another unit above it through
the upper connector, it is automatically configured as
a Slave. If there is no unit above it, then it becomes a
Master.

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 interconnect-
ing 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 connec-
tion, 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 “dou-
ble-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.
