BlueBridge 16 Input x 8 Output DSP Audio Processor

Ideal Use Cases

The AtlasIED BlueBridge BB-168 is designed for installed audio systems that require substantial input capacity, flexible signal routing, and software-configurable digital signal processing. Its 16 analog inputs can each be configured for microphone- or line-level operation, while eight analog line outputs support systems that need multiple processed output paths. This configuration is particularly useful when a project must combine numerous sources, create distinct mixes, manage output processing, or accommodate changing signal-flow requirements.

The available processing modules support applications requiring automatic mixing, matrix routing, equalization, crossover management, feedback control, dynamics processing, and test-signal generation. Software-enabled 48V phantom power also allows compatible microphones to be incorporated without requiring separate phantom-power equipment.

Why Choose This Model

The BB-168 combines open-architecture design software with a broad collection of processing tools. Rather than limiting the installer to a fixed signal path, the processor provides multiple module types for constructing a configuration around the requirements of the audio system. Mixer choices include gain-sharing and gating auto-mixers, a matrix mixer, a standard mixer, and LR and LCR mixers.

Its equalization resources include parametric, graphic, and anti-feedback modules. High-shelf, low-shelf, and all-pass filters are also available. For loudspeaker-system processing, crossover modules provide Butterworth, Linkwitz Riley, and Bessel responses with slopes ranging from 6 to 48dB per octave. Compressor, expander, limiter, and ducker modules address level control and dynamic management within the same processing environment.

Installation and Integration

Each of the 16 inputs is software selectable between microphone and line operation, helping the processor accommodate different analog source types. The eight outputs operate at line level. Input impedance is greater than 10kΩ, and 48V phantom power can be enabled through software. Polarity is also selectable between positive and negative through the graphical user interface.

The electronically balanced gain configuration is specified from 100 to +15dB in 0.25dB steps. These incremental adjustments provide detailed control while configuring input levels. The BB-168 measures 19 inches wide, 1.75 inches high, and 9 inches deep. Height and depth are also specified as 44mm and 229mm, respectively. It weighs 7.2 pounds, or 3.25 kilograms, and has a stated power consumption of 18.5W. The unit is listed to UL60005.

Performance Highlights

High-performance 24-bit analog converters are paired with 40-bit floating-point processing. The stated frequency response extends from 20Hz to 20kHz, while typical unweighted dynamic range is rated at 110dB. Latency is specified at 5ms. The processor also provides greater than 100dB CMRR from 50Hz to 10kHz and stated distortion of 0.002% measured at 1kHz and +4dBu.

These specifications give system designers concrete performance values for evaluating the processor within an analog audio signal chain. A listed refresh rate of 50Hz further defines its operating specifications. For setup and testing, generator modules include sine tone, sign sweep, white, and pink options, allowing signal generation to be incorporated into the configured processing design.

What Makes It Different

The defining feature of the BB-168 is the combination of a 16-input by 8-output analog configuration and an open-architecture software environment. Its processing library covers routing, automatic mixing, tonal adjustment, crossover functions, filters, dynamics, feedback control, and signal generation. This enables several stages of an audio workflow to be assembled within one configurable DSP platform.

The choice between gain-sharing and gating automatic mixers adds flexibility for projects that require automatic microphone management. Matrix, standard, LR, and LCR mixer modules provide additional options for organizing sources and outputs. Software selection of input type, phantom power, and polarity keeps key configuration controls within the graphical interface.

Final Assessment

The AtlasIED BlueBridge BB-168 is a capable choice for installations requiring 16 configurable microphone or line inputs, eight line outputs, and a substantial DSP toolset. Its 24-bit conversion, 40-bit floating-point processing, 5ms latency, 110dB typical unweighted dynamic range, and extensive collection of mixer, EQ, crossover, filter, generator, and dynamics modules provide a clearly defined foundation for customized installed-audio processing. The product includes a 36-month warranty measured from the date of purchase.
