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:

SPN812 8 input, 12 output mixer, 1 RU
SPN1612 16 input, 12 output mixer, 2 RU
SPN1624 16 input, 24 output mixer, 2 RU
SPN2412 24 input, 12 output mixer, 2 RU

Input-only processor models include:

SPN16i 16 channels, 1 RU
SPN32i 32 channels, 2 RU

Other processor models include:

SPNConference teleconference Interface, 1 RU
SPNDNT Dante network interface, 1 RU*

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.

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.

Interconnect Multiple Units

When multiple units are used, interconnect them via the ASPEN ports on the rear panels.

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

Output levels must be set

The settings can be made using the computer interface or with the LCD.

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
Noise reduction filter

Equalization
ADFE (auto digital feedback eliminator)
Compressor

Every output channel includes settings for

Delay
Equalization

Compressor
Limiter

Front Panels

Dual-board models in 2RU chassis include a front panel LCD and rotary-style navigation control for adjustment without the need for a computer interface. Single-board models require a computer interface for setup and adjustment.

The headphone output is used to monitor each final mix for diagnostics and system checkout. LEDs on the right side of the front panel indicate communications through serial and ethernet ports, provide an alert indicating an error, activity during firmware

Headphone Monitor

Used to monitor individual final mix buses as selected on the LCD. Standard 1/4-inch jack and level control. Drives both channels of stereo headphones.
On single board, 1RU models, the processor must be connected to the ASPEN control panel to gain access to the headphone monitor channel selection.

MCU Recovery (recessed pushbutton)

Used in the procedure to recover from an interrupted firmware update procedure. See the section on Firmware Update Procedure for details on usage.

LCD

Allows setup and adjustment of most operating parameters and for minor adjustments without a computer interface.

Navigation/Select Control

Used to navigate menus and make value selections and settings on the LCD.

USB Port

Standard USB connector for the setup and control of a DMTH4 from a Windows® XP, Vista or 7 computer system* with USB interface.

Status LEDs

Comm LED – blinks to indicate USB, RS-232 and ethernet communication

Alert LED – blinks to indicate fault or error, glows white during firmware updates
Power LED – glows to indicate power ON

Above are examples of SPN mixers in 1RU and 2RU versions built around the 8 in/12 outboard. Dual board models share a common power supply, RS-232 and Ethernet ports. The ASPEN ports and Programmable Input and Output ports are dedicated to each board.

Power Inlet

The switching power supply will operate with line voltages between 100 and 240 VAC. The inlet socket is a standard 3-pin C14 type that accepts any cord set with a C13 connector.

Cooling Fan

The microprocessor monitors the internal temperature of the processor and controls the variable speed fan as needed. The 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 monitor- ing, setup and control.

ASPEN Ports

This gigabit bus transports audio and data from one board to the next through CAT-6 cabling (maximum 2 meters or 6.5 ft length) and RJ-45 connectors.

Processors are normally installed with the Master 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.for more information.
Note: 2RU units must have the upper & lower boards connected via CAT5 cable.

Balanced 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 and 17 through 24 on each board are nominal line-level outputs with gain adjustment from OFF, -69 to +20 dB. Channels 9 through 16 on each board are the same, except switchable attenuation of 20 and 40 dB is also available to reduce the output to the “mic level” range.

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 conductors 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.

Caution: Do not overtighten the screws.

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

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.

Audio Inputs – Balanced

Balanced audio sources connect to the processor inputs in a straight “pin to pin” configuration.

Audio Outputs

The line outputs are a balanced differential configuration 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.

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 programmable 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 the ground. When a programmable output is “active,” it conducts current to the ground. When the programmable output is “inactive,” no current flows to the ground. The maximum usable voltage for the programmable outputs is 40 V and they will safely conduct up to 100 mA DC continuously. 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.

Programmable Outputs

Note: The diagram above shows an external DC source powering the relay coil. This is necessary whenever coil voltages exceed 5 volts.

ASPEN to PC RS-232 Port Wiring

Crestron/AMX RS-232 Port Wiring

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 backpropagation through a single cable connection.

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.

Using the LCD

The LCD can be used to perform a simple setup, to check current settings or to make adjustments without using a computer interface.

Boot Screen

Main Window

Navigation Control

The navigation control for the LCD consists of a rotary control and four directional buttons for the selection of menu items and to enter values.
The four outer buttons are referenced as LEFT, RIGHT, UP and DOWN. Pressing the center of the rotary control provides a “select” or “center switch” function.

The LEFT (9:00) functions as a BACK button to return to the previous menu from setup screens as prompted by the symbol in the lower-left corner of the LCD.

Shortcut Buttons

LCD Backlight Toggle: Press both the LEFT and RIGHT (9:00 and 3:00 o’clock) buttons to turn the backlight on and off.
Emergency Mute (panic button): Pressing the UP and DOWN buttons together will mute all outputs to remedy situations such as runaway feedback.
Restore Default Settings (Master Reset): Hold in the LEFT and UP buttons while turning on the power to restore the factory default settings. The Alert LED will glow white during the process, which takes about 75 seconds to complete.

Panel Lock/Unlock

Select the Unlocked/Locked item with the rotary control, press the center switch.

A prompt will appear asking you to enter the passcode.

The factory default passcode is five presses of the center switch. Once the correct passcode is entered, the panel will allow access to the screen items to change the unlocked/locked status, enter a new passcode and save the results.
The passcode can consist of any combination of five successive button presses of the four outer switches and the center switch such as: LEFT > RIGHT > UP > DOWN > CENTER.
After selecting the mode and/or changing the passcode, select SAVE with the rotary control and press the center switch to save the settings.

Press the LEFT (9:00 o’clock) button to return to the previous screen.

Master Reset
Hold the LEFT and UP buttons in at power up to restore factory default settings.

WARNING: Master Reset will remove all stored settings, unlock the control panel and reset the passcode to five center button presses.
Master Reset takes about 75 seconds to complete while the center (white) LED on the front panel stays lit. The display will then return to the Main Window and the right (blue) LED will light up to indicate power ON and a “ready” status.

Initial Setup
The processor requires a minimum setup before it will pass signals:

Input Gain Value
Crosspoint Gain Value
Output Gain Value

These three minimum settings can be made with the LCD or software GUI.

Input Setup
Select [INP] on the Main Window.

Select Mic/Line Input Setup (Input Levels is a dynamic display that shows bar graphs of activity).

Navigate to each cell and enter a value. For microphones, 40 to 50 dB is a normal value. For line levels, 0 dB is a commonly used value. If phantom power is needed, be sure to check the 48V cell for each microphone using the rotary control.

Matrix Crosspoint Setup

Select [MAT] on the Main Window.

Scroll to the desired Crosspoint setting and select it.
The UP and DOWN buttons can also be used to scroll the menu items.

Global System Settings

Select [SYS] in the Main Window to access a setup menu for a variety of global settings including headphone monitoring, date and time setup, timer and event programming, front panel lockout, network interface settings and others.

Network Interface
IMPORTANT: Always consult your network administrator before attempting to connect and configure a processor for a network interface.
The [SYS] tab menu also includes Network Settings.

The settings must be correctly set before connecting to a network.

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 on all units simultaneously or turn on Slave units before turning on the Master unit.
Check the LCD display on the Master unit to see if it has detected all the Slaves.

The Master unit will always be number one in the stack as shown here, and each slave will be numbered in the order that it is connected with the cabling of the ASPEN port jacks.

Software and Firmware Updates

Check for the latest versions of the control panelsoftware and to see that the hardware includes the latest firmware.
ASPEN models with a front panel LCD will display the firmware version on the LCD and in the control panel GUI after the software is installed. Other models display the firmware version in the GUI only. Firmware updates require that the ASPEN software be installed to enable a connection and use the update utility included in the software.

Obtaining Updates

The latest versions of software and firmware are downloadable from the Aspen Support section on the Lectrosonics website.
Lectrosonics home page: http://www.lectrosonics.com

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 by 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 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 are 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 damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
