JL Audio Monoblock 500/1 Amp 500 Watts!! $400 obo
Used but in great working condition JL Audio 500/1 amp. The Amp gots a few scratches on it but doesn't affect it at all.
Rated Power: 500 W RMS @ 1.5W-4W (11V-14.5V)
THD at Rated Power: <0.05%
S/N Ratio: >95dB below rated power
(A-weighted,20-20KHz noise bandwidth)
Frequency Response: 5 Hz - 500 Hz (+0,-1dB)
Damping Factor: >500 @ 4W/50 Hz,>250 @ 2W/50 Hz
Input Range: switchable from 200mV-2V RMS
to 800mV-8V RMS
Dimensions: 13.4"L x 9.25"W x 2.36"H
Features:
Differential-Balanced Input Topology: (1 pair of inputs)
ON-board crossover:fully adjustable (40-200 hz)selectable slope (12 db or 24 db per octave)
Preamp Output: 2-channel (independent active filter, parallel with amp filter or full-range)
Bass EQ: parametric with variable boost up to 15dB and Remote Bass Option.
Infrasonic Filter: fully-variable 24dB/octave from 15-60 Hz
Signal-Sensing Turn-On: permits operation without remote lead
Dual mono speaker output connections: accept up to 8ga.wire
+12V and Ground connections: accept up to 4ga.wire
This JL Audio amplifier is truly a breakthrough in technology! Think about it, while connecting the unit, you don't even have to worry about remote wires, the sophisticated technology senses it for you, and turns it on automatically! Not only that, you don't even have to worry about what ohms you are running your subs, the amplifier senses and runs it accordingly! How's that for technology? This is truly a breakthrough in car audio!
The 500/1 is a single-channel, class D subwoofer amplifier with a power rating of 500 watts into any load between 1.5 ohms and 4 ohms. Features include the Regulated Intelligent Power Supply, which is responsible for the single power rating, differential inputs, buffered preamp outs, internal crossovers with variable cutoff frequencies and selectable slopes, a parametric bass boost circuit with wired remote, and a variable infrasonic filter.
Performance
The 500/1 is the first class D unit that we’ve seen from JL Audio and, like the rest of their amplifier lineup, this unit can vary its output voltage potential to match the load being driven, thereby producing essentially the same output power into a wide range of loads. In the class A/B amps, this is accomplished by reducing the amp’s rail voltage when driving lower impedances. In the class D amps, the duty cycle of the high frequency carrier signal is reduced when driving lower impedances, which produces the same effect.
The sidebar with the specs pretty much speaks for itself. The 500/1’s adaptive and tightly regulated output appears to work quite well, providing about 600 watts into resistive loads under a wide range of test conditions. The amp also seems more than happy driving reactive loads and posted an impressive 733 watts into 2 ohms
