Product Research


Overview: The Bose ControlSpace SP-24 is a DSP sound processor designed for auditoriums, houses of worship, retail stores, restaurants and many other applications. With 2 input channels that can be routed to any of the 4 outputs, the SP-24 features 9-bands of input and output equalization, band-pass filters, delays, peak limiter, gain, and signal polarity reversal, for full system control. All input and output jacks are balanced XLR's with output signals running to an amplifier or powered speakers.  Configurations can be saved as Custom Scenes and Bose has included more than 150 Presets that are designed for specific speakers and venues. A clean, ergonomic front panel gives access to the main functions while the SP-24 Editor software (downloadable from Bose's web site) gives full editing control.

Loudspeaker Library: The SP-24 comes packed with over 150 factory-created equalization curves, based off of specific models of  Bose speakers and types of applications, while Editor software provides intuitive graphical tools for optimizing any passive or powered loudspeaker.

USB: A USB type-B (2.0) port is provided for computer connectivity. This allows for system configuration, programming, signal level monitoring and firmware updates using the SP-24 Editor software. Minimum system requirements are:

  • Windows XP Professional, service pack 2 or later.
  • Windows 7, Professional or Ultimate.
  • Intel Pentium 4 850 Mhz processor or better.
  • 512 MB RAM
  • 100 MB disk space available.
  • Minimum screen resolution of 1280 x 768

Inputs/Outputs: Each of the 2 input and 4 output jacks are balanced, 3-pin, XLR connectors providing the cleanest signal transmission to and from the processor.

Front Panel: The SP-24's front panel LCD and controls are purposely designed to make it easier to select Custom or Preset scenes, input and output gain, delay parameters, and Utility functions such as Factory Reset and a User Lockout option that keeps the front panel from being tampered with. Front panel LEDs for both input channels provide Signal present and Clip indications.

SP-24 Editor Software: At the heart of the SP-24 is its DSP which is edited and configured using the SP-24 Editor software for PC (downloadable from the Bose web site, Mac not supported). The signal chain options for each of the inputs are as follows:

  • Input Level: Level meters for both A and B inputs are provided with a range from +12 to -60 dB and include a Mute for each channel.
  • Router: The Router section allows you to select any Input channel and assign it to any of the 4 Outputs. Output channels can be muted if not being used.
  • Input EQ: Both the A and B input channels can have their own 9-band EQ, either Graphic or Parametric. Each band can be raised or lowered by +/- 18 dB and has its own Bypass button. A Bypass All is included to bypass the Input EQ completely.
  • Crossover: The SP-24 includes Band-pass filters for each of the 4 output channels. Each filter section includes a High-pass and a Low-pass crossover that can be used independently or combined for a Band-pass filter. Other options include the filter Type, with options like Butterworth and Bessel with various slopes for each. A Bypass is available for each crossover.
  • Bose Loudspeaker Equalization: Each output signal chain includes a dedicated Bose Loudspeaker EQ stage. Bose has included equalization curves for various models of speakers, all of them being editable. Bose Speaker types include: FreeSpace, Panaray, LT, and Legacy EQ Curves. A Bypass is available for each channel.
  • Zone EQ: The next option in the signal chain is the Zone EQ for each output channel. This EQ has the same options as the Input EQ and can be either Graphic or Parametric.
  • Delay: Each of the output channels can have up to 170 ms of delay applied, adjustable in both 1.0 ms and 0.02 ms increments, and includes a Bypass option.
  • Output Limiter: Four Peak Limiters are available, one per channel, with a Threshold setting that can be set from 0 to -40 and a Bypass.
  • Output Level: Each of the four output channels has a level control, ranging from 0 to -60, as well as Mute and Polarity Reversal options.

Custom Scenes: The ControlSpace SP-24 can store up to four Custom Scenes which can be recalled from the front panel or the SP-24 Editor software. Scenes are a "snapshot" of all the settings and parameter configuration created in the SP-24 Editor software that can be stored and recalled inside the processor. Additional Scenes can be stored on a computer.
