v 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. Y ou can also reduce the amount of outboard gear that is required to transport, set-up and operate as part of the sound system.
1 WHA T IS A SPEAKER MANAGEMENT SYSTEM? A Speaker Management System uses digital signal processing to accom- plish multiple functions that affect the audio signal between the mixer and the power amplifiers. These functions include crossover , equalization, delay , limiting, high-pass and low-pass filtering as well as signal distribu- tion.
2 FRONT P ANEL ® 1. LCD The 2x20 backlit LCD displays the program and programming choices of the unit. 2. <Back/Next> These buttons allow naviga tion for selection of sub-menus and some parameter values. 3. Menu This is one of two buttons that will access the front panel programming.
3 REAR P ANEL 1. Power Jack This accepts a standard IEC type AC bayonet plug. 2. RS232 Interface 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.
4 QUICK ST AR T ® NOTE: This section will describe navigation of the front panel controls as follo ws: The button to press will be shown in ALL CAPIT ALS. For QUICK ST ART , a number following in parentheses (#) will also be included. These refer to the same names and numbers as shown in Figure 1, Front P anel Controls and Indica tors.
5 QUICK ST AR T 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 tha t can be selected will show on the display .
6 INST ALLA TION ® Y our DS24/DS26 was carefully packed at the factor y and the packaging was designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage tha t may have occurred in transit.
7 OPERA TION There are two methods of creating and selecting programs on the DS24/DS26. 1.The first method uses the front panel controls of the unit and requires stepping through menus to access the proper parameter that needs adjusting. Once programs have been saved to the onboard memor y , call- ing up a program is quite simple.
8 OPERA TION ® you back, simply hit EXIT and start a gain. Where an additional "ENTER" press is required to write the selection to memory , the screen will prompt you with "[ENTER] to Confirm". The LED display also offers some hints.
9 OPERA TION 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: P arameters can be viewed, but cannot be adjusted. MUTE buttons are valid.
10 OPERA TION ® A.Determines whether the outputs will stay muted on power up until manually switched off (Mute Hold) or the level will gradually fade up to the operating level (Fade In). The fade-in time is fixed. B.Fade-in: Mutes are off, but Output channels rise to programmed levels gradually .
11 OPERA TION 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.
12 OPERA TION ® 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.
13 OPERA TION gain to the program level after the threshold point has been exceeded by the incom- ing signal. Generally , set shorter attack times on outputs tha t are feeding mids and highs and longer attack times for lows and subs.

19 GRAPHICAL USER INTERF ACE (GUI) 2.Click NEW . A dialog box labeled “Unit” will appear in the screen. 3.Device ID assigns a number between 1 and 64 to the unit. 4.Select Unit T ype selects whether the unit is a DS24 or a DS26. 5.Format selects the main crossover mode for the unit.
20 GRAPHICAL USER INTERF ACE (GUI) ® Y ou should no w see the global view . This is the main screen from which to make your programming choices. 8.4.3 T op Line Menu 1.File gives the typical Windows file management choices. 2.Config provides two choices: Modify and RS-232.

22 CREA TING A PROGRAM ® Once the device type and crossover type have been selected, the main screen will show blocks for each programmable section. The term “pro- gram” as used here is equivalent to “preset” as used on other program- mable devices.
23 CREA TING A PROGRAM 9.4 OUT 1, OUT 2, etc. Each tab selects an output channel. Use this screen to program crossover frequencies, fil- ter type, and up to five parametric EQ’ s. In addition, the same programming choices as on the GAIN screen are duplicated here, but just for the selected output channel.
24 CREA TING A PROGRAM ® Use the sliders to select values for Frequenc y ., Q and Gain (cut/boost). An additional check box for FLA T will bypass all value selections. At the bottom of the screen are forward and back arrows to step through the five PEQ’ s.
