Item(s) for Sale:
Rare Black JL Audio 1000/1 and 450/4
Item(s) Description/Condition:
Both items are used, but very little and are in MINT condition. The only marks on either are around the mounting holes.
Specs:
1000/1
Amplifier Topology: H-Bridge, Class D Mono
with impedance optimization and patented
discrete drive circuitry
Power Supply: Pulse width modulation-regulated
switching power supply
Rated Power: 1000W RMS x 1 @ 1.5 - 4Ω (11 - 14.5V)
THD at Rated Power:
Signal to Noise Ratio: >95 dB referred to rated power
(A-weighted, 20 Hz - 20 kHz noise bandwidth)
Frequency Response: 5 - 250 Hz (+0, -3 dB)
Damping Factor: >500 @ 4Ω/50 Hz, >250 @ 2Ω/50 Hz
450/4
CHANNELS 1 & 2:
Amplifier Topology: Class AB with patented Absolute
Symmetry™ dual N-Channel MOSFET output design
Power Supply: Independent, pulse width modulationregulated
switching power supply with multistage
impedance optimizing circuitry.
Rated Power (Stereo):
150W RMS x 2 @ 1.5-4Ω (11V - 14.5V)
Rated Power (Bridged):
300W RMS x 1 @ 3-8Ω (11V - 14.5V)
THD at Rated Power:
(20 Hz-20 kHz)
Signal to Noise Ratio: >108.5 dB referred to rated power
(A-weighted, 20 Hz-20 kHz noise bandwidth)
Frequency Response: 5 Hz - 30 kHz (+0, -1dB)
Damping Factor: >200 @ 4Ω per ch. / 50 Hz, >100 @ 2Ω
per ch. / 50 Hz
Slew Rate: ± 25V/μs
CH 1&2 Filter: State-variable, 12 dB/octave Butterworth or
24 dB/octave Linkwitz-Riley Low-Pass or High-Pass with
continuously variable cutoff frequency from 50 - 500 Hz,
switchable to a range of 500 - 5000 Hz, via x10 switch.
Can also be cascaded from Channel 3&4 filter’s cutoff
frequency to operate as a bandpass filter for tri-amp
configurations. Defeatable.
LF Boost: Single-band, fixed-frequency (48 Hz), fixed “Q”
+6 dB boost. Defeatable. Port for optional remote bass
control to provide variable boost control from 0 to +15 dB.
