Any or all of the 24 DSP channels can also be routed to up to 32 CobraNet channels on the network. Unlike other configurable DSP boxes, the intrinsic process- ing latency of the BASIS 914lz is both short and fixed at 9- DataPorts 10- XLR/TRS combo inputs (line level)

DSP-30. The BASIS 914lz brings all that technology together in one compact, powerful, easy to use system. We are confident that your new BASIS 914lz will provide years of dependable service and we hope it will help you, the sys- tem designer and implementer, to express your creative audio system ideas.

The BASIS 914lz supports two distinct kinds of network activity; the first is audio transport via CobraNet, and the second is control and monitoring via QSControl.net. The user can choose to install one network for CobraNet traffic and a second separate network for QSControl.net traffic.

It should be noted here that while the CobraNet port on a BASIS 914lz is restricted to repeater LAN or switch LAN deployments, QSControl.net is a TCP/IP standards-compliant network system and therefore supports operation on network repeaters, switches and routers.

BASIS products all of the time without having to physically switch between them. You still get the great performance of TCP/IP over Ethernet. (And we believe QSC's advanced 4th generation networking software provides the best performance of any networked audio control system available today including Ethernet based systems from competitors.)

Example #3 - Single Wire Interface: Here all QSControl.net and CobraNet traffic shares the same single CAT-5 cable between the BASIS 914lz and an unmanaged Ethernet switch. The QSControl.net system manages traffic flow efficiently and reliably so that all audio and control data is delivered to its appropriate destination anywhere on the network.

BASIS 914lz control and monitoring (including the system controller) and a second dedicated network for CobraNet audio. As with the previous example, as many BASIS 914lz units may be connected as there are switch ports available. All BASIS units will be able to communicate with the computer. All will have CobraNet audio.

Example #5 - Two-Wire Interface (separate network hardware): Example #5 is conceptually similar to example #4. The difference here is that separate networks are created by providing each local area network (LAN) with its own network switch. Therefore, traffic segmentation is physical rather than logical. Example #5 also pro- vides an additional level of fault tolerance, although at the expense of additional network hardware.
2-pin terminal block connector Mounting The BASIS 914lz 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.

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 accept- able for most applications). We recommend your system meet the following minimum requirements: 1- IBM PC compatible computer with a Pentium 4 processor.
Configuration Memories The BASIS 914lz has non-volatile storage locations that contain settings for the device as well as DSP signal flow. The storage loca- tions make it possible to set up the BASIS for different situations and quickly recall the setup with or without QSControl.net software...

AC Power Cord Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the BASIS 914lz. 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.
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 BASIS 914lz. To con- nect the cable, orient the connector properly, then push into the receptacle until it is firmly seated;...
LCD Display and Controls The BASIS 914lz 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.

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 infor- mation when first setting up a network system. Once user moves to a different screen, the last screen accessed becomes the new power up default.
2- Connect a CAT-5 crossover cable from the computer’s network interface card (NIC) to the BASIS QSControl jack (example 1, page 6). 3- Reconnect the power cord to the BASIS 914lz (turn it on). Using the BASIS LCD display and controls, navigate the menu to the IP Address and make a note of it.

AC power is properly applied to the BASIS. 19- Click on the “+” sign of the BASIS 914lz 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 block and the current DSP configuration of the BASIS will be displayed.
16 may be selected to forward to the signal processing chain (DSP engine). The BASIS 914lz will support the delivery of up to 32 channels via up to 4 outbound bundles (to the network). Of these 32 channels, up to 24 may be unique (processed individually...
If the BASIS 914lz 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 BASIS 914lz that will enable you to communicate with it.

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 BASIS 914lz to post its menu text. The “h” key is the Help prompt for the BASIS 914lz. A text menu will appear. This is sent by the BASIS 914lz and will detail your options and instructions for changing the address 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 BASIS 914lz you want to communicate with in the text box and click OK.
