Important Safety Instructions

Installation and Startup Guide

This symbol, wherever it appears, alerts
you to the presence of uninsulated danger­ous voltage inside the enclosure -- voltage
that may be sufficient to constitute a risk of
shock.

This symbol, wherever it appears, alerts
you to important operating and mainte­nance instructions in the accompanying
literature. Please read the manual.

When using your telephone equipment, basic safety
precautions should always be followed to reduce the
risk of fire, electrick shock and injury to persons, includ­ing the following:

1) Read these instructions.

2) Keep these instructions.

3) Heed all warnings.

4) Follow all instructions.

5) Do not use this apparatus near water.

6) Clean only with a dry cloth.

7) Do not block any ventilation openings. Install in ac­cordance with the manufacturer’s instructions.

8) Do not install near any heat sources such as radia­tors, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.

9) Do not defeat the safety purpose of the polarized
or grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding
type plug has two blades and third grounding prong.
The wider blade or the third prong are provided
for your safety. If the provided plug does not fit into
your outlet, consult an electrician for replacement of
the obsolete outlet.

10) Protect the power cord from being walked on or
pinched particularly at plugs, convenience recepta­cles, and the point where they exit from the appara­tus.

11) Only use attachments/accessories specified by the
manufacturer.

12) Use only with the cart, stand, tripod,
bracket, or table specified by the
manufacturer, or sold with the ap­paratus. When a cart is used, use
caution when moving the cart/ap­paratus combination to avoid injury
from tip-over.

13) Unplug this apparatus during lightning storms or
when unused for long periods of time.

14) Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.

15) WARNING -- TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE THIS AP­PARATUS TO RAIN OR MOISTURE.

16) The AC mains plug, or appliance coupler shall be
readily available to the operator as a means of
power disconnection, if applicable.

17) Unit shall be connected to a MAINS socket outlet
with a protective earthing connection.

18) Do not use this product near water for example,
near a bathtub, washbowl, kitchen sink or laundry
tub, in a wet basement or near a swimming pool.

19) Avoid using a telephone (other than a cordless
type) during an electrical storm. There may be a
remote risk of electric shock from lightning.

20) Do not use the telephone to report a gas leak in the
vicinity of the leak.

21) Use only the power cord and batteries indicated in
this manual. Do not dispose of batteries in a fire.
They may explode. Check with local codes for pos­sible special disposal instructions.

22) “CAUTION: To reduce the risk of fire, use only No.
26 AWG or larger (e.g., 24 AWG) UL Listed or CSA
Certified Telecommunication Line Cord”

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired opera­tion.

CAUTION: Changes or modifications not expressly
approved by Lectrosonics, Inc. could void the user’s
authority to operate the equipment.

This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interfer­ence when the equipment is operated in a commercial
environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may
cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user
will be required to correct the interference at his own
expense.

Installation and Startup Guide

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 accord­ing 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 Mas­ter 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 main­tain 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:

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 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:

• Inputlevelsmustbeset

• Crosspointsmustbedened

The settings are made using the computer interface.

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).
Details for this critical setting are included in the Instal­lation Guide for the SPN Conference processor.

Signal Processing

Audio quality is significantly improved by using the vari­ous 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lter

• Equalization

• ADFE(autodigitalfeedbackeliminator)

• Compressor
