    INTRODUCTION ® Thank you for choosing the BBE DS24/DS26 Speaker Management System. This product will enable you to obtain the best possible performance from your loudspeaker system. You can also reduce the amount of outboard gear that is required to transport, set-up and operate as part of the sound system.

  • Page 7: What Is A Speaker Management System, Crossover, Equalization, Delay, High Pass And Low Pass Filters

    These functions include crossover, equalization, delay, limiting, high-pass and low-pass filtering as well as signal distribu- tion. Programs may be created, selected and edited with the DS24/DS26's front panel controls. However, to create new programs, it is best to use the included free PC software and configure the programs using the graphical user interface (GUI) and a Windows PC.

  • Page 8: Front Panel

    FRONT PANEL ® 1. LCD The 2x20 backlit LCD displays the program and programming choices of the unit. 2. <Back/Next> These buttons allow navigation for selection of sub-menus and some parameter values. 3. Menu This is one of two buttons that will access the front panel programming. This one is used primarily to select which program to call up, edit or save.

  • Page 9

    Connect this to the serial port on a PC using the included cable or other standard DB-9 type cable. With the software installed, the PC can now monitor and program the DS24/DS26. 3. XLR Input These are balanced (Pin 2 Hot) XLR inputs that accept the signal from the (usually main) outputs of the mixer.

  • Page 10

    Before hooking up the system, make sure that all items are OFF, especially the power amps. Use high quality balanced XLR mic cables to make the connections. The feeds from the DS24/DS26 at "front of house" can also be sent through the audio snake returns to the amp stacks if used in a live setting.

    QUICK START Depending on the mode selected, other options will appear for this level of the menu, primarily concerned with input and output assignments. Some assignments are fixed with the crossover type selected. Only those assignments that can be selected will show on the display. Either the BACK/NEXT (2) buttons or the Parameter dial will work for stepping through the selections.

  • Page 12: Rack Mounting, Connectors

    6.1 RACK MOUNTING The DS24/DS26 fits into one standard 19” rack unit of space. Please allow at least an additional 4” depth for the connectors on the back panel. Though this device does not generate significant heat, be sure that there is enough air space around the unit for cool- ing.

    2.The second method uses the included Graphical User Interface (GUI) software run on a Windows PC. The computer connects to the DS24/DS26 and gives a more global view of the parameters and the choices for set- tings.

    7.2.1.4 Store a Xover: Store all the configuration settings of a X-OVER. The DS24/DS26 will store up to 10 program configurations in user memory locations. (An unlimited number can be stored on a PC or other PC accessible memory.) Each of the 10 programs can have a name containing up to 16 letters and numbers.

    OPERATION Press MENU, NEXT and ENTER. Then use the NEXT/BACK and ENTER buttons to adjust the Security Submenu. The various locking modes are as follows: 1.LOCK: Changes only: Parameters can be viewed, but cannot be adjusted. MUTE buttons are valid. 2.LOCK: Changes + View: Parameters cannot be viewed or adjusted.

    1.RS232 baud rate and address code setting: Select 2400, 4800, 9600, 19200, 38400 baud rate according to different PC capabilities. 2.Remote ID NUM: Select 1~32. Use this function when multiple DS24/DS26 units are used. Master Control unit is set as 1; slave units are set with subsequent numbers.

    OPERATION 7.6.1.2 Outputs: Press NEXT again and the screen will display an Output (Op1 = Output 1). Set the desired input gain level. At this point you can use the BACK/NEXT buttons to step through each of the parameters for the currently selected output. Press the GAIN button again to go to the next Output and program all of its parameters.

  • Page 18: Limiter

    OPERATION ® HiPass: frequency range 10Hz~16.0KHz LoPass: frequency range 35Hz~22.0KHz Use HPF and LPF together to define the frequency band for this channel of the crossover. 7.6.1.7 PEQ: Set the parameters for the five available bands of parametric EQ. Press the PARAM dial to toggle between the three parameters on the display.

    The time should be chosen care- fully as the danger of dynamics distortion usually increases with shorter attack times. The attack time of the DS24/DS26 can be set within a range of 1 to 100 mil- liseconds.
