This tiny amplifier packs a serious full-range punch, delivering a staggering 100 watts to each of its six channels.NexD Technology: The breakthrough that makes this much power possible in such a small chassis is JL Audio's NexD ultra-high-speed switching design, which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency.Combine with a subwoofer amp:With the M600/6, you have lots of great options. Use it as a six-channel satellite amplifier with 75W x 4 @ 4 Ω, or bridge four of its channels to create a staggered power four-channel amplifier with 200W x 2 @ 4 Ω to one pair of satellites and 75W x 2 @ 4 Ω to a secondary pair of satellites. You can also drive two subwoofers with 200W each, plus a pair of satellites with 75W x 2.Filters: The M600/6 includes a 12 dB / octave filter for each channel bank, which can be configured as a low-pass or high-pass filter and offers continuously variable cutoff frequency selection from 50-500 Hz.Remote control: With the addition of an HD-RLC remote level control (sold separately), you have the ability to control the level of two, four or all six of the amplifier's channel levels from a remote location.Built for the marine environment: This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.Key FeaturesNexD amplifier technologies produce exceptional audio quality, unsurpassed total efficiency and high power from very compact amplifier designsJL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down eventsFrequency Response: 12 Hz - 22 kHz (+0, -1dB)Signal/Noise Ratio, referred to highest rated power: >104 dB below rated power (A-weighted, 20 Hz - 20 kHz noise bandwidth)Signal/Noise Ratio, referred to 1 W: >84 dB (A-weighted, 20 Hz - 20 kHz noise bandwidth)Damping Factor @ 4 Ω: >150 / 50 HzDamping Factor @ 2 Ω: >75 / 50 HzTotal Harmonic Distortion + Noise @ Rated Power: <1% @ 2 Ω per Ch.Input Voltage Range @ RCA Inputs: 100 mV - 4 V
