Description
JL Audio M600/6
This incredibly flexible amplifier packs a serious full-range punch, and delivers a staggering 100 watts to each of its six channels into 2 Ω (14.4V, 1% THD). The breakthrough that makes this much power possible in such a small chassis is our NexD™ ultra-high-speed switching design, which allows for full bandwidth Class D operation with extremely low distortion and outstanding efficiency.
With the M600/6, you have lots of great options. Use it as a six-channel satellite amplifier with 75 W 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 75 W x 2 @ 4 Ω to a secondary pair of satellites. You can also drive two subwoofers with 200 W each, plus a pair of satellites with 75W x 2. 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. 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.
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.
