Introduction The DSP 322ua provides signal processing needs for an integrated functioning system. In conjunction with QSControl.net software, the DSP 322ua enables the user to design, test and deploy professional audio reinforcement systems ranging in size from one to hundreds of channels. A standard Windows computer is the principle user-interface for controlling the overall DSP/QSControl.net system. However, the DSP 322ua also offers a front panel interface for accessing critical functions. A single QSControl.net server computer can support several clients running QSC's latest Venue Manager software. Thus, the sound system can be operated via several computers, roaming wireless laptops, tablets, etc., all at the same time, from anywhere a connection to the QSControl.net network is available. The QSControl.net network can also be managed from a single computer running both the client and the server.

All basic functions of the DSP 322ua continue to operate with or without a control computer connected to the network. The configurable DSP engine provides all of the functions necessary to handle the amp/loudspeaker portion of a signal chain, such as very flexible and precise crossovers, delays, equalization, compression/limiting, etc. Audio enters a DSP 322ua through the 8 universal analog inputs. The inputs accept everything from mic to line level and are equipped with software-selectable +48V phantom power. Unlike many configurable DSP boxes, the intrinsic processing latency of the DSP 322ua is both short and fixed at 0.396 milliseconds. With analog inputs and analog outputs, the total delay is 2.354 milliseconds.

Both software and firmware can be easily updated over the network. In the future, QSC will be adding new capabilities to QSControl.net. Our latest code releases and access to upto-date information on QSControl.net are available at www.qscontrol.net. We invite you to visit us there. Block Diagram 4 We are confident that your new DSP 322ua will provide years of dependable service and we hope it will help you, the system designer and implementer, to express your creative audio system ideas. Introduction - Networking the DSP 322ua Notes on Network System Design: As with any communications system, the reliability and performance of a local area network (LAN) is intimately related to the designer's skill and knowledge in implementing a topology that is robust, efficient and standards-compliant. Proper network design is even more critical in distributed multimedia systems. Therefore, it is important for the system designer to realize that some conventional network practices could have an impact on the ability of the audio control system to provide real-time performance. Although each network design is unique and may carry its own performance requirements, the following points will assist in building an audio network that is trouble free and efficient. First, we recommend designing a network that is to be used exclusively for “QSControl.net” communications. Rest assured, your DSP 322ua has been designed to communicate over standard10Base-T Ethernet using standard network protocols and standard network hardware. As such, DSP 322ua products are tolerant of conventional data communications services and products such as those that offer file sharing, e-mail services, and Internet access. However, these conventional data services can consume network resources and ultimately degrade the performance of your DSP 322ua product. Therefore, we strongly encourage designers to limit traffic on their audio control network to QSControl.net related communications. Second, your DSP 322ua should not be installed on the same LAN or “virtual” LAN (VLAN) with distributed audio and/or video services. While coexistence with conventional data communications services is tolerated to some extent, sharing a network with distributed audio and/or video is not. Distributed media services can monopolize a network by sourcing high-bandwidth broadcast content to all end stations. As a result, the performance of unintended recipients suffers. An experienced designer can apply techniques such as data filtering to block media content, but the typical installation requires compliance to this second point in order to ensure reliable performance from your QSControl.net network. Third, we recommend designing networks with “switch” technology rather than deploying Ethernet repeaters. Doing so will provide a network that is scalable and efficient and one that will offer real-time performance from your DSP 322ua products in the presence of multiple control computers. To learn more about network design rules and system compliance visit the QSC network resources page at http://www.qscaudio.com/ products/network/resources.htm. The following examples will help get you started, but they just scratch the surface of what can be achieved with advanced networking… Example #1 - QSControl.net X-over mode: This is the simplest connection you can make between the DSP 322ua and your computer. Use a CAT-5 crossover cable connected between the DSP QSControl port and your computer's Network Interface Card, (NIC). No network switch is required. With QSControl.net server and client software installed and running on your computer you will be able to completely set up your DSP 322ua. 5 Example #2 - Connection to an Unmanaged Switch: Switches can be connected to other switches to build larger networks; all of the normal networking principles apply. Here all QSControl.net traffic resides on a single unmanaged Ethernet switch. The DSP 322ua connects directly to the switch. A computer hosting a QSControl.net server application also connects directly to the switch. All configuration and monitoring of the DSP 322ua is performed via the PC. 6 Example #3 - Connection to a Managed Switch: This example illustrates a connection with a managed Ethernet switch. The switch is configured with multiple virtual local area networks (VLANs). Ethernet deliveries can only reach destination ports belonging to the same VLAN from which it was sourced. The figure shows a separate VLAN for QSControl.net traffic and a separate VLAN for CobraNet audio traffic. This configuration essentially provides a dedicated network for QSControl.net (including the system controller) and a second dedicated network for CobraNet audio. As with the previous example, as many units may be connected as there are switch ports available. Switches can be connected to other switches to build larger networks; all of the normal networking principles apply. 7 Unpacking There are no special unpacking precautions. However, it is recommended you keep the original packing material for reuse in the rare event that service be required. If service is required and the original packing material is not available, ensure that the unit is adequately protected for shipment (strong box of appropriate size, sufficient packing material to prevent load-shifting or impact damage) or call QSC’s Technical Services Department for packing material and a carton. What is included in the carton: Item Description 1 DSP 322ua 2 Self-adhesive rubber feet 3 Hardware Manual (this document) 4 QSControl.net Software CD 5 IEC Power Cord 3 x #18 AWG 6 3-pin terminal block connector 7 2-pin terminal block connector Quantity 1 4 1 1 1 18 10 Mounting The DSP 322ua can be used in or out of an equipment rack. Rack mounting is optional. Adhesive rubber feet are included for non-rack mount installations. Use them to prevent the unit from scratching or marring support surfaces. Rack Mounting Rack mount the DSP 322ua by supporting it from underneath while aligning the mounting holes with the threaded screw holes in the rails; install all four mounting screws and washers and tighten securely. Ensure use of all four mounting screws in order to minimize the chance of bending or distorting the rack mount ears. If the DSP 322ua is to be transported while in a rack, we recommend supporting the rear of the chassis. This will help prevent the unit from being damaged from the increased mechanical stresses of portable and mobile use. The DSP 322ua’s chassis includes integral rear mounting tabs for securing to the rack mounting ears. Be certain not to block the cooling air ventilation openings on the sides of the chassis. Be certain not to block the cooling air ventilation openings on the sides of the chassis. 8 Computer Requirements & Software Installation Installing QSControl.net is easy. All you need to do is choose the folder where the program is to be stored (the default setting is acceptable for most applications). We recommend your system meet the following minimum requirements: 1- IBM PC compatible computer with a Pentium 4 processor. 2- Processor speed of 1 GHz (2 GHz or faster recommended for systems with 30 or more BASIS/RAVE/DSP units). 3- 512 megabytes of RAM (1 gigabyte recommended for systems with 30 or more BASIS/RAVE/DSP units). 4- Hard drive with at least 500 MB of free space for the program and files you generate. 5- Display resolution of 1024 X 768, 16-bit color. 6- CD-ROM drive to install the software. 7- 10BaseT/100BaseTx network interface card (the DSP322ua uses only 10Mbit (10BaseT) connection) 8- Windows XP Professional, XP Home, Windows 2000 SP2 (or better), or Windows NT4.0 SP6a operating system. Windows 95, 98 and ME platforms are not supported. Note: If system is used for real-time adjustments and configuration of audio systems, we recommend all Windows Power Options (located in the Windows Control Panel) features be disabled. Display, hard drive, system standby and hibernation settings should be set to “Never”. This avoids waiting for the system to “wake-up” if adjustment is needed after an elapsed period of time. To Install QSControl.net: 1- Start your computer and start Windows. 2- If there are any programs running, please close them now. Be sure to leave Windows running. 3- Place the QSControl.net CD-ROM in your CD-ROM drive. If your system supports the Auto Run feature installation begins automatically, otherwise, you can click Start on the task bar, click Run, and browse for the file named setup.exe from the CD. 4- Click the Install QSControl.net button. 5- Follow the installation instructions on the screen. To Uninstall QSControl.net: 1- Click the Start menu button and choose Settings/Control Panel. 2- Double-click the Add/Remove Program icon. 3- Select QSControl.net from the list, then click Add/Remove. 4- Click Yes to confirm you would like to uninstall QSControl.net. General Information & Configuration Memories Network The network should be operable and QSControl.net software should be installed/running on the system controller computer. Configuration Memories The DSP 322ua has non-volatile storage locations that contain settings for the device as well as DSP signal flow. The storage locations make it possible to set up the DSP for different situations and quickly recall the setup with or without QSControl.net software using the front panel controls. 9 Connections AC Power Cord Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the DSP 322ua. Plug the AC line connector into the AC outlet. The power supply will accept from 100 to 240 Volts AC, 47 to 440 Hertz, without any changes. If a different type of IEC power cord is required than the one supplied with your 322ua, contact QSC’s Technical Services Department. QSControl Connect one end of a category-5 cable terminated with an RJ45 plug into the QSControl receptacle. Insert the RJ45 plug into the receptacle with the lock-tab oriented toward the bottom of the DSP 322ua and push firmly until the connector locks into place (usually an audible “click” can be heard). Connect the other end to the appropriate QSControl.net network port. QSControl connection: accepts ruggedized or normal shell-less RJ45 plugs. Analog Universal Audio Inputs Eight balanced audio inputs are provided, CH 1 INPUT - CH 8 INPUT. They accept everything from mic level to line level signals and are equipped with software-selectable +48V phantom power. Plug the input signal terminal block connectors into the input receptacles. Connection pin-out is printed on the rear label for reference. Refer to the illustrations for balanced and unbalanced connections. Use balanced audio inputs whenever possible. Each input has software-selectable +48V phantom power. Use caution when connecting equipment (particularly unbalanced equipment). Analog Audio Outputs Eight balanced audio outputs are provided, CH 1 OUTPUT - CH 8 OUTPUT. Plug the output signal terminal block connectors into the output receptacles. Connection pin-out is printed on the rear label for reference. Refer to the illustrations for balanced and unbalanced connections. Use balanced audio outputs whenever possible. Omni In The six Omni In connectors are two-pin terminal block connectors. They accept contact closure, TTL logic signals, 0-5 VDC control voltages, or 10k ohm variable resistors. The contact closure and logic devices accommodate on/off or state-change events; the variable resistor input provides full 8-bit resolution allowing for incremental-change events. Refer to the illustrations for connection recommendations. NOTE! +48 volts is the absolute maximum that can be applied to the + pin without damage. Voltage is with respect to chassis or the - pin. Analog audio input and output- balanced connection. Analog audio input and output- unbalanced connection. Note jumper wire between - and ground. Omni In connections. Variable input must be 10k ohm variable resistor. Contact closure input can be a switch or relay contacts. These inputs can operate software “devices”. Negative (-) terminal is at chassis potential. Logic Out The four Logic Out connectors are two-pin terminal block connectors. They provide CMOS logic level compatible signals for external devices. 10 Logic Out connections. Negative (-) terminal is at chassis potential. Positive (+) terminal logic level is switched using software. Relay Out Two sets of relay contacts are provided, RELAY OUT 1 and RELAY OUT 2. Contacts are floating and rated for 30VDC, 1A. There is one common terminal, one normally-closed contact terminal and one normally-open contact terminal. These are labeled as C, NC and NO on the rear panel. When the relay is not energized, the C terminal is connected to the NC terminal and the NO terminal is not connected; when the relay is energized the C to NC connection is opened and the C to NO connection is closed. Relay Out connections. Refer to text, at left, for explanation. RS-232 The RS-232 is a utility serial port for accessing certain diagnostic features and setup. Connect to an available COM port on your PC and communicate using a terminal control program such as Windows Hyperterminal. Use a normal serial data cable with a DB-9 male plug to connect to the DSP 322ua. To connect the cable, orient the connector properly, then push into the receptacle until it is firmly seated; tighten the retaining screws “finger tight”. Communications should be 9600 baud, no parity, 8 data bits, 1 stop bit, and flow control Xon/Xoff. LED Indicators When the DSP 322ua is plugged into a properly functioning AC outlet, it will power up and briefly display a welcome screen on the LCD display. POWER Indicator- This blue indicator illuminates when the DSP 322ua is plugged into a properly functioning AC source. There is no power switch on the DSP 322ua. This helps to prevent accidental system shutdowns. DIAGNOSTIC Indicator- This red diagnostic LED reports several possible operational conditions. During boot-up, it is used to continually blink a “dot-dash” pattern if the power-on memory self-test fails. During normal operation, if any non-recoverable system fault occurs, the diagnostic indicator will remain on, requiring a power restart. If this condition persists, contact QSC’s Technical Services for assistance. The diagnostic LED is also used to indicate an update is in progress during a remote firmware update cycle. First, the LED will blink slowly, indicating the memory erase cycle, then it will blink rapidly, indicating the memory write cycle. NOTE! During a firmware update, it is critical the unit remain powered on for the entire process in order to complete successfully. The diagnostic LED may also be controlled by using the QSControl.net software. This feature is particularly helpful for identifying a particular unit. (continued, next page) 11 LED Indicators (continued) QSControl Status (Port) Indicators- There are three LEDs on the front and rear panels labeled RX, TX and LINK. These indicate the status for the QSControl.net network. Their functions are described below. RX (receive)- This indicator illuminates any time the DSP 322ua receives data from the network. TX (transmit)- This indicator illuminates whenever the DSP 322ua transmits data onto the network. LINK STATUS- The corresponding indicator illuminates when the DSP 322ua is connected to an operating network. SIGNAL indicators- These indicators will illuminate green for input signals -40dB to -10dB below full scale; yellow for signals between -10dB to -2dB below full scale; red for -2dB to full scale (or clip). LCD Display and Controls The DSP 322ua has a 2 line X 16 character LCD display. The display and the multi-function push-button switches on either side provide data access and editing capability. The push-button switches on either side of the display are used to navigate through the menus. The rotary select/accept knob is active for many displayed items allowing you to scroll through choices by rotating the control, and accepting choices (entering) by pushing in on the control. The accessible menus and sub menus may appear differently than the example shown. Software updates may occasionally improve the interface. The basic navigation flow for the DSP 322ua menu system is shown on the following page. Front Panel Password Lockout The password lockout provides the ability to restrict access to all of the editable parameters available on the LCD front panel. This feature is enabled or disabled via QSControl.net software only (refer to the “General Tab” area and click on the “Front Panel Password” button). When the lockout feature is enabled, all front panel LCD functions are readable, but editing of parameters is now password protected. While in this mode, any attempt to edit a parameter requires the user to enter the Front Panel Password. The default factory password is “qsc”. The password is stored in the DSP unit and can be changed using the QSControl.net software. Once the password has been correctly entered, the DSP will allow edits to the parameters. After 5 minutes of inactivity, the DSP will automatically reset the Front Panel Password lockout. Re-entry of the password will be required to resume editing. The lockout mode can be deliberately disabled via the “Disable Edits” checkbox in the Front Panel Password menu of the QSControl.net software. 12 LCD Navigation Map Left side buttons have screen dependent functions. This read-only screen is the “out of the box” default display after power up. This is the most desired information when first setting up a network system. Once user moves to a different screen, the last screen accessed becomes the new power up default. Use rotary data wheel to edit data. Rotate to move cursor and push to accept change. Boot Screen Right side buttons serve as up/down navigation. Arrow characters indicate right side button context. If additional menus are available, the arrow character will be shown. *Note: After successful password entry, all screens with editable parameters will have read write capability. Without password entry, these screens will be read-only. 13 Getting Started This section outlines one of the simpler methods of getting familiar with your DSP 322ua and the QSControl.net software. The goal of this procedure is to get your computer and the DSP 322ua connected and communicating and the QSControl.net software installed and running. After the software is installed and running, refer to the software’s Help file for all software related operation/issues. Note! The default password for the DSP 322ua is “qsc” (no quotes, lower case). 1- Turn off the computer and unplug the power cord from the DSP 322ua. 2- Connect a CAT-5 crossover cable from the computer’s network interface card (NIC) to the DSP 322ua QSControl jack (example 1, page 5). 3- Reconnect the power cord to the DSP 322ua (turn it on). Using the DSP 322ua LCD display and controls, navigate the menu to the IP Address and make a note of it. In steps 12 and on, you will need to change the IP address of the DSP 322ua or your PC. 4- Turn on the PC and start Windows. You must have Administrator rights and be signed on as Administrator in order to install the QSControl.net program. Ensure you are signed on to the computer as the Administrator. 5- Place the QSControl.net CD-ROM in your CD-ROM drive. The install wizard should start. If not, you can also select Start then Run and browse for the file named setup.exe from the CD. 6- The installer queries the computer for available drive space and other information. If required MDAC library (Microsoft) files are not already on the computer, the library files are installed. You must accept the Microsoft software agreement in order to install the MDAC library. It may be necessary to reboot the computer after library installation. 7- At the prompt for “Client/Server” selection, keep both Client and Server selected. This will be appropriate for general use. 8- When prompted “Select Installation Folder”, specify the installation directory or accept the default location. 9- You will be prompted to select an installation accessible by everyone (non-secure) or an installation accessible only to you (secure). Select the appropriate Everyone or Just Me box and continue. Installation proceeds. 10- Reboot only if your computer prompts you to do so. 11- Select Network Connections in the control panel. Select Properties. Right-click Local Area Connection, and view its properties. Highlight the Internet Protocol (TCP/IP) tab and view its properties. You will see an entry field for the IP address. Decide whether you want to change the IP address of your computer to be similar that of to the DSP 322ua (easiest if you have many DSP 322ua units) or if you want to change the IP address of your DSP 322ua to be similar to that of the computer. This is a network management decision. 12- Change the IP address of the DSP 322ua (or computer) to be compatible with that of the computer (or DSP 322ua). Typically, this is done by making the IP address of one of the devices 1 digit different in the last octet (group of digits in IP address). If changing the computer’s settings, write down the current values, in case you want to revert later. 13- The subnet mask address should be exactly the same for both the computer and the DSP 322ua. The Gateway address should not be altered as it is not used. 14- After you are satisfied with all your settings, close all open windows and start the QSControl.net program. Select Start, All Programs, QSControl.net, Venue Manager. 15- The login screen should open. The default password is “qsc” (lower case, no quotation marks). Select “Log on to Local Computer” and click OK. 16-The QSControl.net Venue Manager window will open. A Startup Tips screen will be visible the first time Venue Manager is launched. Optionally, the Startup Tips screen may be disabled by un-checking the box in it’s lower left corner. It is highly recommended the user become familiar with each of the tips listed on this screen. After reviewing the tip(s), close the Startup Tips screen. 14 Getting Started (continued) 17- Select Device, Add Device, from the menu. A new window will open prompting you to name the device. Name it logically, such as DSP 1, or similar. Select the Device Type and select DSP 322ua. At the Password prompt, enter “qsc” (lower case, no quotation marks). This is the device password, separate from the software password. The default, in both cases, is “qsc”, but you are free to change either or both. Enter the IP address of the DSP 322ua and click OK. 18- The DSP 322ua will now appear in the inventory root (left side of screen, first with a red “x”, then a yellow exclamation point, then a normal icon). If the DSP 322ua does not eventually show in the inventory root, check that a crossover cable is used (only for DSP 322ua connected directly to PC), check the cable connections, verify IP addresses are set correctly, verify Subnet masks are set correctly, and verify AC power is properly applied to the DSP 322ua. 19- Click the “+” sign of the DSP 322ua in the inventory root, then the “+” sign of the Flashed Configs. Click on the config with the loudspeaker icon. A view of applicable device tabs will open. Click the DSP tab and the current DSP configuration of the DSP will be displayed. 20- Right click on the Design Editor icon in the lower left of your display; select “New”. A new window opens; select DSP 322ua for the device type. 21- Click on Help to access the software’s Help system. All software operation is covered in the on-line help file. Operation of the DSP 322ua is accomplished with the included QSControl.net software. No software operation is covered in this hardware manual. After installing your software, open the Help file and follow its recommendations. The software Help file includes the most recent information available for your DSP 322ua. 15 Operation QSControl Port The QSControl port operates on a 10BaseT Ethernet network. This port is one of the primary means for connecting QSControl.net to the DSP 322ua. The port may connect directly to a PC's 10BaseT or 10/100 (auto-sensing or auto-negotiating) network interface card using a crossover cable. Data from the QSControl port may also pass through network repeaters, network switches and routers. We strongly recommend the use of network switches to facilitate higher bandwidth and dedicated connections. 1 Minute Autosave Timer and Power Cycling The active configuration has a special feature associated with it. Any changes made to a parameter during operation will start an internal timer which will trigger an automatic save of the configuration data. The save procedure begins after 1 minute of parameter change inactivity. If the DSP322ua is then power cycled, upon restart, the previous settings data will be preserved in the active configuration. Utility/Diagnostic Functions Safe Mode Switch Location of Safe Mode switch: The front panel has a small access hole on the left side, just left of the Power indicator. It is not labeled to help prevent accidental use. The Safe Mode switch can be operated by using a paperclip (or similar item) inserted into the access hole and pushing. Safe Mode: Use if the DSP 322ua becomes inoperable (or behaves in completely unexpected ways) after updating firmware. If the DSP 322ua operates in an unexpected way or is not responding to any communications after a new firmware file is uploaded to it, it is likely the file was corrupted during transfer. If this occurs, there is a “backup” program in the DSP 322ua that will enable you to communicate with it. How to put the DSP 322ua into Safe Mode: 1- Turn off the power to the DSP 322ua by unplugging it from the AC outlet. 2- Depress the Safe Mode switch and keep it depressed while plugging the unit back in (power on). 3- The DSP 322ua is now in “safe mode”. You may release the switch. You should now be able to re-establish limited TCP/IP communications with the DSP 322ua. Once communication has been re-established, the file transfer can be tried again or the old application file used until the source of the data transfer problem can be found. Also, QSControl.net WILL NOT communicate with the DSP 322ua if it is in “safe mode”. You may communicate only using TFTP, Telnet, or RS-232. RS-232 Serial Port I/O Interface The RS-232 connector on the rear panel is used as a serial port input/output (I/O). This I/O port is used for accessing Ethernet/IP settings, stand alone control capabilities, system “health” data, firmware version information and other related data. Should any system problems arise, the data that may be accessed through this interface can help to track down the problem. The most common items that might be used are “Display Network Settings” and “Enter Network Setup”. Many of the remaining selections would typically be used for troubleshooting purposes along with a QSC technical representative prompting you to access particular menu items so the data can be interpreted. Connection is made using a normal serial cable between your computer’s serial port and the RS-232 port of the DSP 322ua. Once properly connected, a “dumb-terminal” program (such as Hyper Terminal, a widely used version on most Windows-based PC’s) is started and communication established between the PC and the DSP 322ua. Following is the basic procedure for starting up Hyper Terminal, naming the connection, specifying the communications settings and an example of “what you should see” for a text-menu once the communications link has been established. If programs other than Hyper Terminal are used, you will need to follow your software’s instructions for establishing communications through your PC’s COM (serial) port. 16 Utility/Diagnostic Functions (continued) RS-232 Communications Procedure: 1) Connect the RS-232 port of the DSP 322ua to an unused serial port (COM port) of a PC using a normal (straight-through) serial cable. 2) Open the HyperTerminal program. This program is usually started by clicking the Windows Start icon, selecting Programs, then Accessories, Communications, and finally, highlighting the Hyper Terminal folder and clicking on its icon. 3) After starting Hyper Terminal, a Connection Description window will pop-up. It will require that you name your connection. Enter a name for your new connection (example: DSP 322ua) and click OK to continue. 4) Next, Hyper Terminal needs to know how to “talk” to the DSP 322ua. This selection depends on which port on your PC the cable is connected to. Ignore the first three entry fields (phone number information) and go directly to the Connect using entry field and click on the down arrow for the drop-down menu selection. Select the port the DSP 322ua is connected to and click OK to continue. The Properties window should appear next. 5) The Properties window for the selected COM port should now be active. For the Port Settings, use the following information so communication between the DSP 322ua and the computer is in the same “language”. Bits per Second: 9600 Data Bits: 8 Parity: none Stop Bits: 1 Flow Control: Xon/Xoff Once you have set the properties as outlined, click OK to continue. If all the connections and communications settings are correct, the main Hyper Terminal window will open. 6) The Hyper Terminal main window will appear next, but blank. Type the letter “h” (for help) and then the “Enter” key. This will prompt the DSP 322ua to post its menu text. The “h” key is the Help prompt for the DSP 322ua. A text menu will appear. This is sent by the DSP 322ua and will detail your options and instructions for changing the address information. From this main-menu you will need to make your menu choices and follow the instructions in the following sub-menus or screens. Although many of the instructions and tests may not pertain to a specific setup or troubleshooting situation, you may be asked to run certain tests by a QSC technical representative. The results of these tests will help to troubleshoot any problems. The most common user item that might require settings to be changed would be the IP address information. This would be useful if the IP address was inadvertently changed to an unrecognized address and subsequently you were unable to “talk” to the DSP 322ua over the network. This situation would require the Display Network Settings and Enter Network Setup items to be accessed for re-assigning a valid IP address. IP ADDRESS ASSIGNMENT- ONLY REQUIRED FOR ATTACHING TO EXISTING NETWORKS! DO NOT CHANGE THE COMMUNICATIONS SETTINGS OF THE DSP 322ua UNLESS CERTAIN OF YOUR ACTIONS. THE FACTORY-PROGRAMMED IP ADDRESS CAN BE ACCESSED USING THE FRONT PANEL DISPLAY MENU SYSTEM. RECORD THIS IP ADDRESS SHOULD YOU NEED TO RETURN TO THE INITIAL SETTINGS. Telnet Access The RS-232 features can also be accessed via Telnet. The Microsoft Telnet application is a Windows program. Consult Windows documentation for Telnet information. Basic procedure for opening a Telnet session: 1- To open the Telnet session- Click START, select RUN, type “Telnet” followed by a space, then the IP address of the DSP 322ua you want to communicate with in the text box and click OK. 2- If the address entered was correct and network communications with the DSP 322ua are successful, the Telnet session should open. 3- Now you have the same options that are available in the Serial Port I/O (RS-232) interface section. 17 Preliminary Specification IN Dynamic Range (AES-17, -60dB Method, all sensitivities) unweighted >110dB A weighted >113dB OUT THRU >112dB >115dB >108dB >111dB Distortion (20Hz-20 KHz, all sensitivities) Gain= 0 - 30dB Gain >30dB <0.008% THD+N <0.05% THD+N <0.009% THD+N <0.009% THD+N <0.009% THD+N <0.05% THD+N Crosstalk (20Hz - 20KHz) inter-channel (max) inter-channel (typ) intra-channel (max) intra-channel (typ) >75dB >90dB >85dB >100dB Frequency Response 20Hz - 20KHz (max) 20Hz - 20KHz (typ) ± 0.5dB ± 0.2dB Program Inputs Connector Type Type Grounding Pinout Input Impedance (nom.)
