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.
Installation and Startup Guide 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. LCD The headphone output is used to monitor each final mix for diagnostics and system checkout.

SPN Mixers Hardware Installation 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. Retaining Screw (Do not overtighten) Two wire cables should have a jumper between the processor (–) input and ground. Source Caution: Do not overtighten the screws. 5-pin depluggable connector Do not leave more than 1 mm of exposed wire beyond the connector.
Installation and Startup Guide Audio Outputs Programmable Inputs The line outputs are a balanced differential configuration which can drive balanced or unbalanced inputs on other audio equipment with the wiring shown here. Shield Destination Output Balanced output to a balanced input is a straightforward “pin to pin” configuration. Balanced output to balanced destination Programmable inputs are provided to enable external control over a variety of parameters.

Installation and Startup Guide Using the LCD Shortcut Buttons The LCD can be used to perform a simple setup, to check current settings or make adjustments without using a computer interface. Boot Screen • 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.
SPN Mixers After selecting the mode and/or changing the passcode, select SAVE with the rotary control and press the center switch to save the settings. Select Mic/Line Input Setup (Input Levels is a dymanic display that shows bar graphs of activity). A progress bar will appear as the settings are saved. 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.
Installation and Startup Guide Adjust to the desired value with the rotary control and press the control to store the value. (the Crosspoint Gain setting screen is shown here as an example) Rear Panel Controls Select [RPC] in the Main Window to access a setup menu to configure external controls such as pots and switches. While settings can be made with the LCD interface, it is recommended that you use the software GUI instead.
SPN Mixers 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. Software and Firmware Updates Check for the latest versions of the control panel software 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.
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 .
SPN Mixers Software Installation NOTE: Uninstall previous version before installing the software. The example shown here illustrates the installation procedure using Windows XP. The screens that appear at each step using another operating system will vary, but the general steps are very similar. Insert the disk into the drive and wait for the opening screen to appear. Click on Install ASPEN Software to launch the installer. It is usually best to accept the default folder for the installation.
Installation and Startup Guide 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.
SPN Mixers Using the Software GUI for Minimum Setup Define inputs, crosspoints and outputs on the appropriate tabs for a required minimum setup. An Input, crosspoint and output must be defined to create a path that allows the processor to pass a signal. This required minimum setup can be accomplished quickly using the sofware GUI. Launch the ASPEN software. The first screen to appear is blank with tabs at the top of the window to select the desired action.
Installation and Startup Guide 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.
SPN Mixers 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.
