8 Input x 8 Output DSP Audio Processor

Ideal Use Cases

The AtlasIED BlueBridge BB-88 is designed for installed audio systems that require eight analog inputs, eight analog outputs, and configurable digital signal processing. Its software-selectable microphone-or-line inputs accommodate systems using either source type, while eight line outputs provide a matching output count. Available matrix, standard, LR, and LCR mixers support a range of routing and mixing configurations. Gain-sharing and gating auto-mixers address projects involving multiple active inputs. Parametric, graphic, and anti-feedback EQ modules, together with crossover, filter, generator, and dynamics tools, make the BB-88 suitable for installations that need signal routing, frequency adjustment, level control, and frequency-band processing within one platform.

Why Choose This Model

The BB-88 combines an 8 x 8 analog configuration with open-architecture design software and a broad collection of available processing tools. Each input can be configured for microphone or line operation, and 48V phantom power is software enabled. Polarity is selectable through the GUI, providing another software-controlled setup option. High-performance 24-bit analog converters are paired with 40-bit floating-point processing. The available modules cover core audio functions including mixing, equalization, filtering, crossovers, signal generation, compression, limiting, expansion, ducking, and automatic mixing. This combination allows the processor to address multiple system functions through a single configurable design environment.

Installation and Integration

The processor measures 19 inches wide, 1.75 inches high, and 9 inches deep, with a listed weight of 7.2 pounds or 3.25 kilograms. Power consumption is specified at 18.5 watts. During configuration, the design software can be used to select microphone or line input operation, enable 48V phantom power, and choose positive or negative polarity through the GUI. The electronically balanced gain configuration is listed as 100 to +15dB in 0.25dB steps, allowing incremental gain adjustment within the stated range. Input impedance is greater than 10kΩ, and the output type is line level. The unit is listed to UL60005 and includes a 36-month warranty from the date of purchase.

Performance Highlights

The BB-88 has a specified frequency response of 20Hz to 20kHz and a typical unweighted dynamic range of 110dB. Latency is listed at 5ms. Common-mode rejection ratio is greater than 100dB from 50Hz to 10kHz, while distortion is specified at 0.002% when measured at 1kHz and +4dBu. High-performance 24-bit analog conversion supports the processor’s analog input and output stages, while the listed 40-bit floating-point processing provides the internal processing format. These published values define the unit’s analog and digital performance characteristics for system planning. The technical data also lists a 50Hz refresh rate.

What Makes It Different

The range of available processing modules distinguishes the BB-88 from a processor limited to basic input and output adjustment. EQ options include parametric, graphic, and anti-feedback modules. Crossover choices include Butterworth, Linkwitz Riley, and Bessel types, with slopes ranging from 6 to 48dB per octave. Filter modules include high shelf, low shelf, and all pass. Mixing tools extend from standard, matrix, LR, and LCR mixers to gain-sharing and gating auto-mixers. Generator modules include sine tone, Sign Sweep, white, and pink options. Compressor, expander, limiter, and ducker modules provide the listed dynamics functions. The open-architecture design software enables these available tools to be applied according to the system configuration.

Final Assessment

For an installation centered on eight analog microphone-or-line inputs and eight line outputs, the AtlasIED BlueBridge BB-88 offers a clearly defined channel layout and an extensive processing toolkit. Its 24-bit converters, 40-bit floating-point processing, 5ms latency, software-enabled phantom power, and GUI-selectable controls provide concrete capabilities for configuration and operation. The available mixer, EQ, crossover, filter, generator, and dynamics modules make it a versatile choice when several audio-processing functions must be organized within one 8 x 8 DSP platform.
