  • Page 3 BASIS devices in a system are configured, a computer is no longer required on that system’s network. All basic func- tions of the BASIS 922az continue to operate with or with- out a control computer connected to the network. The configurable DSP engine provides all of the functions...
  • Page 4 Introduction (continued) Unlike other configurable DSP boxes, the intrinsic process- ing latency of the BASIS 922az is both short and fixed at 0.417 milliseconds. When analog input and analog outputs are used, the total delay is 2.355 milliseconds. The delay does not change regardless of the DSP configuration, unless the configuration intentionally adds more delay.
  • Page 5 The BASIS 922az 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 traffic.
  • Page 6 This applies primarily to existing CM16a and RAVE networks. For this very reason we continue to support connectivity to network repeater hardware with the BASIS 922az. Support for network repeaters exist only with the Two Wire Interface. That is to say that the QSControl port and the CobraNet port must be connected to separate repeater LANs.
  • Page 7 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.)
  • Page 8 Example #3 - Single Wire Interface: Here all QSControl and CobraNet traffic shares the same single CAT-5 cable between the BASIS 922az 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.
  • Page 9 BASIS 922az control and monitoring (including the system controller) and a second dedicated network for CobraNet audio. As with the previous example, as many BASIS 922az 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.
  • Page 10 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.

  • Page 11: Rack Mounting

    5-pin terminal block connector Mounting The BASIS 922az 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.
  • Page 12 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.

  • Page 13: Amplifier Setup

    Configuration Memories The BASIS 922az 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...
  • Page 14 Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the BASIS 922az. 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 922az. To con- nect the cable, orient the connector properly, then push into the receptacle until it is firmly seated;...

  • Page 16: Lcd Display And Controls

    LCD Display and Controls The BASIS 922az 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.
  • Page 17 LCD Navigation Map (typical) Boot Screen Left side buttons have screen dependent functions. This read-only screen is the “out of the box” default dis- play after power up. This is the most desired information when first setting up a net- work system.

    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 922az (turn it on). Using the BASIS LCD display and controls, navigate the menu to the IP Address and make a note of it.
  • Page 19 Subnet masks are set correctly, and verify AC power is properly applied to the BASIS. 19- Click on the BASIS 922az in the inventory root. A view of applicable device tabs will open. Click the DSP tab 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 922az 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...

  • Page 21: Reset Switch

    If the BASIS 922az 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 922az that will enable you to communicate with it.
  • Page 22 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 922az to post its menu text. The “h” key is the Help prompt for the BASIS 922az. A text menu will appear. This is sent by the BASIS 922az and will detail your options and instructions for changing the address information.
