- Page 3 Unlike many configurable DSP boxes, the intrinsic process- ing latency of the RAVE 522aa is both short and fixed at 0.396 milliseconds. When analog input and analog outputs are used, the total delay is 2.354 milliseconds. The delay does not change regardless of the DSP configuration, unless the configuration intentionally adds more delay.
- Page 4 DSP-30. The RAVE 522aa brings all that technology together in one compact, powerful, easy to use system. We are confident that your new RAVE 522aa 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.
- Page 5 Second, CobraNet audio must traverse either a repeater domain or a network switch domain. The point here is that the CobraNet port on a RAVE 522aa must connect directly to, and only to, either a repeater LAN or a switched Ethernet LAN. Hybrid networks containing both repeaters and switches are not permitted on the audio segment.
- Page 6 CM16a and RAVE networks. For this very reason we continue to support connectivity to network repeater hardware with the RAVE 522aa. 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 Example #2 - CobraNet X-over mode: This is the simplest connection you can make between the RAVE 522aa and any of the other RAVE/BASIS models. You use a CAT-5 crossover cable connected between the CobraNet ports of each unit. No network switch is required. This connection allows audio to pass between the two RAVE/BASIS units over CobraNet.
- Page 8 Example #3 - Single Wire Interface: Here all QSControl and CobraNet traffic shares the same single CAT-5 cable between the RAVE 522aa 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 Example #4 - Two-Wire Interface (shared network hardware): This example illustrates the Two-Wire Interface 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.
- 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
2-pin terminal block connector Mounting The RAVE 522aa 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 RAVE 522aa 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 RAVE for different situations and quickly recall the setup with or without QSControl.net software... - Page 14 AC Power Cord Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the RAVE 522aa. 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.

“finger tight”. Communications should be 9600 baud, no parity, 8 data bits, 1 stop bit, and flow control Xon/Xoff. LED Indicators When the RAVE 522aa is plugged into a properly functioning AC outlet, it will power up and briefly display a welcome screen on the LCD dis- play. -
Page 16: Lcd Display And Controls
LCD Display and Controls The RAVE 522aa 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) 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. Once user moves to a different screen, the last screen accessed becomes the new power up...

2- Connect a CAT-5 crossover cable from the computer’s network interface card (NIC) to the RAVE QSControl jack (example 1, page 6). 3- Reconnect the power cord to the RAVE 522aa (turn it on). Using the RAVE 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 RAVE. 19- Click on the RAVE 522aa in the inventory root. A view of applicable device tabs will open. Click the DSP tab and the current DSP configuration of the RAVE will be displayed.

If the RAVE 522aa 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 RAVE 522aa 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 RAVE 522aa to post its menu text. The “h” key is the Help prompt for the RAVE 522aa. A text menu will appear. This is sent by the RAVE 522aa and will detail your options and instructions for changing the address information.
