Wavtech - LINK1400.8PLUS 8 Channel Plus Series Amplifier w/Summing 175 x 8 @ 2 ohms (Remote Capable w/Optional RLC) - Black/Gray

Enhance your factory or aftermarket radio and sound system with the Alpine OPTIM 8. Featuring a built-in 8-channel amplifier with Hi-Res Audio playback up to 96kHz/24Bit, the OPTIM 8 is the all-in-one sound solution to amplify and effortlessly sound-tune your system in minutes.

The KXMA 800-watt eight-channel amplifier is one of the most flexible marine power pieces available today. Gain crossover and bass-boost conrols are protected behind a gasket-sealed panel as is the control cover hiding the settings creating a water-resistant barrier to key controls. KickEQ™ delivers as much as an 6dB of extra bump with a simple turn of the knob. A powerful 24dB crossover is also included letting you quickly tune your system to perfection.FeaturesClass D AmplifierGain Control With "Gain Match" LED IndicatorFail-safe Integration Technology CircuitryVariable 24dB Crossover & KickEQ™ 6dB Variable Bass BoostDSP-Controlled PreampStainless-Steel Mounting Hardware IncludedWhat's in the BoxKXMA800.8 8-Channel Full-Range Class D Marine AmplifierMounting HardwareManualSpecificationsDimensions (W x H x D): 8-5/16” x 2-1/8” x 14-3/4”Frequency Response [Hz]: (amp 1&2) 10-20k +0/-1dB; (mono) 10-160Input SensitivityHigh Level 250mV-10VLow Level 125mV-5VSignal-To-Noise Ratio: >95dB a-weightedActive Crossover(amp 1 and amp 2) 24dB/octave Off/ HP/LP variable 10-5kHz w/ 10x switch(amp 3 and amp 4) 24dB/octave Off/ HP/LP/BP variable HP 10–500Hz; variable LP 40–5kHz w/ 10x switchKickEQ™ BOOST: Variable 0-6dB centered 40Hz

The ARC Audio X2800.8 DSP is an 8-channel Class-D amplifier with an integrated 12-channel DSP, engineered for modern OEM integration and active system design. Built around an Analog Devices ADAU1462 32-bit processor and AKM Velvet Sound ADC/DAC architecture, it delivers low-noise signal conversion, precise tuning control, and flexible routing in a compact chassis. Eight bridgeable amplifier channels provide 50 W x 8 at 4 Ω or 85 W x 8 at 2 Ω, with the option to bridge for up to 170 W x 4 at 4 Ω. A 10 Hz–22 kHz frequency response and up to 8 V of RCA pre-out voltage give installers the bandwidth and headroom needed for high-performance speakers and external amplifiers. The onboard DSP offers 12 channels of processing, 4 assignable RCA outputs, and a full toolset for crossovers, EQ, delay, phase, summing, and mixer routing, all managed through ARC Audio’s DNA software. The X2800.8 DSP accepts up to eight balanced analog inputs (RCA or speaker-level) with 0.5–32 V sensitivity, plus a digital coaxial input supporting sample rates up to 96 kHz. Auto-sense turn-on, adjustable turn-on/turn-off timing, and a remote turn-on output simplify integration with factory and aftermarket electronics. iDatalink Maestro AR compatibility allows direct communication with select OEM source units while retaining factory features and enabling channel reassignment inside the DSP. A compact footprint, triple 30 A fuse bank, and fan-assisted cooling make the X2800.8 DSP suitable for under-seat, side-panel, or OEM-location installations where space and airflow are limited. With 8 channels of power, 12 channels of DSP control, and robust OEM integration options, it is designed for real-world multi-channel and active front-stage systems where tuning accuracy and reliability matter more than marketing hype.
