Total Control. Compact Integration.<\/span><\/p><p>Born from ARC Audio\u2019s passion for clean design, easy installation, and pro-grade tuning with honest specifications, the Blackbird DSP amplifier delivers unmatched flexibility and power in a single DSP-amplified solution. With 8 fully bridgeable speaker channels, 4 additional DSP-controlled RCA outputs, and tuning powered by ARC Audio\u2019s DNA software interface, the Blackbird is built for everything\u2014from daily driver upgrades to elite competition systems.<\/p><p>Built on a high-performance 32-bit Analog Devices ADAU1462 DSP core and equipped with premium AKM Velvet Sound ADCs and DACs, the Blackbird delivers up to 1,000 watts of clean, real-world power across its 8 speaker outputs. Whether you\u2019re running a fully active 3-way front stage, bridging channels for powerful midbass, or powering all 8 channels to factory speaker locations while feeding a subwoofer via its RCA DSP outputs, the Blackbird adapts to your system design and sonic goals. All 12 output channels\u20148 amplified, 4 preamp\u2014are fully independent and configurable.<\/p><p>Unlike competing solutions, Blackbird\u2019s fully bridgeable output architecture and dedicated RCA DSP outs make it ideal for hybrid systems. Pair it with ARC\u2019s Nighthawk amplifier when more subwoofer output is needed, or expand into the rest of ARC\u2019s upcoming DSP amplifier lineup\u2014Blackbird stays at the center of it all.<\/p><p>System tuning is handled through ARC Audio\u2019s Pro-Series DNA software, offering one of the most powerful tuning environments in the industry. Enjoy access to 444 bands of EQ, assignable all-pass and shelving filters, per-channel signal delay, phase control, and a vast range of crossover slopes. The Blackbird supports input voltages from 0.5V to 32V, includes high-resolution digital inputs, and is fully iDatalink Maestro AR compatible\u2014ensuring seamless integration into a wide range of modern OEM systems.<\/p><p>And like all ARC Audio amplifiers, Blackbird is CTA-2006 compliant and conservatively rated. No inflated numbers. No creative testing methods. Just honest performance that exceeds expectations and published specifications.<\/p><p>Key Highlights:<br \/>8 bridgeable speaker outputs (up to 250W x4 bridged)<br \/>4 fully independent DSP-controlled RCA outputs (up to 8V)<br \/>96kHz \/ 32-bit DSP resolution with AKM Velvet Sound ADC\/DAC\u2019s<br \/>Powered by ARC Audio\u2019s DNA Tuning software utility<br \/>iDatalink Maestro AR compatible for OEM system integration<br \/>Up to 4 user presets, PSC or LR-2 remote compatibility<br \/>Advanced configuration capabilities for a wider range of applications<\/p><p>Whether you&#8217;re installing for clarity, power, or total control, the Blackbird sets the standard for what\u2019s possible in a compact, all-in-one DSP amplifier.<\/p><\/div><\/div><\/div><\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-tab-title elementor-tab-mobile-title\" aria-selected=\"false\" data-tab=\"2\" role=\"tab\" tabindex=\"-1\" aria-controls=\"elementor-tab-content-2452\" aria-expanded=\"false\">Specifications<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-2452\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"2\" role=\"tabpanel\" aria-labelledby=\"elementor-tab-title-2452\" tabindex=\"0\" hidden=\"hidden\"><table class=\"demo\"><tbody><tr><td>Processor Type<\/td><td>Integrated DSP Amplifier<\/td><\/tr><tr><td>Processor Resolution<\/td><td>Fixed Point Native 32-Bit<\/td><\/tr><tr><td>Main DSP Processor<\/td><td>Analog Devices ADAU1462<\/td><\/tr><tr><td>ADC (Analog to Digital Converter)<\/td><td>(Dual) AKM Velvet Sound 5558B<\/td><\/tr><tr><td>DAC (Digital to Analog Converter)<\/td><td>(Dual) AKM Velvet Sound AK4438<\/td><\/tr><tr><td>Total DSP Channels<\/td><td>12<\/td><\/tr><tr><td>RCA Channels Out<\/td><td>4<\/td><\/tr><tr><td>RCA Output Voltage<\/td><td>Up to 8V<\/td><\/tr><tr><td>\u00a0<\/td><td>\u00a0<\/td><\/tr><tr><td>Total Amplified Output Channel<\/td><td>8<\/td><\/tr><tr><td>Stereo @ 4 Ohms<\/td><td>8 x 75 Watts<\/td><\/tr><tr><td>Stereo @ 2 Ohms<\/td><td>8 x 125 Watts<\/td><\/tr><tr><td>Bridgeable Speaker Outputs<\/td><td>Yes<\/td><\/tr><tr><td>Bridged @ 4 Ohms<\/td><td>4 x 250 Watts<\/td><\/tr><tr><td>Bridged @ 2 Ohms<\/td><td>(Not Recommended)<\/td><\/tr><tr><td>Other Channels @ 4 Ohms<\/td><td>N\/A<\/td><\/tr><tr><td>Other Channels @ 2 Ohms<\/td><td>N\/A<\/td><\/tr><tr><td>Fuse Rating<\/td><td>3 x 30 Amp<\/td><\/tr><tr><td>Amplifier Operating Voltage Range<\/td><td>8.0V &#8211; 17.1V<\/td><\/tr><tr><td>Adjustable Class-D Switching Frequency<\/td><td>Yes &#8211; Via DNA User Software<\/td><\/tr><tr><td>Built-in Fan Cooled<\/td><td>Yes<\/td><\/tr><tr><td>\u00a0<\/td><td>\u00a0<\/td><\/tr><tr><td>Input Channels (Analog)<\/td><td>8<\/td><\/tr><tr><td>Input Channels (Analog Type)<\/td><td>Balanced (RCA or Speaker Level)<\/td><\/tr><tr><td>Input Sensitivity (Analog)<\/td><td>.5V &#8211; 32V<\/td><\/tr><tr><td>Input Impedance (Analog)<\/td><td>10k Ohms<\/td><\/tr><tr><td>Input Gain Type<\/td><td>&#8220;Dedicated&#8221; Selection by channel &#8220;Pairs&#8221; in input Mixer Utility<\/td><\/tr><tr><td>Optical Input<\/td><td>Toslink &#8211; Yes<\/td><\/tr><tr><td>Digital Coaxial Input<\/td><td>Yes &#8211; Requires D.O.C.
