Mono Subwoofer Amplifier: The JL Audio 600/1v3 is a class D
monoblock subwoofer amplifier. With its regulated power supply, the rated output
is 600 Watts RMS x 1-channel into a load of 1.5Ω to 4Ω, with an input
voltage of 11V to 14.5V. The signal to noise ratio is >95 dB and a total
harmonic distortion is <0.05%, both measured at rated power (600 watts RMS).
The amplifier's frequency response is 5-250Hz and it is not designed for driving
full range speakers.
R.I.P.S. (Regulated Intelligent Power Supply): The JL Audio
R.I.P.S. system ensures consistent power delivery over a wide range of battery
voltages and load impedances, providing the rated power output at any impedance
from 1.5Ω to 4Ω and at any vehicle voltage from 11V to 14.5V.
- Regulated Power Supply: The power
supply adjusts to maintain the amplifier's rated power
output and low distortion operation over a wide range
of vehicle voltages (11V-14.5V), so the amplifier's
output remains stable in real-world car audio
- Intelligent Power Supply: An Intelligent
circuit monitors output current to optimize the amplifier's
output power over a wide range of load impedances (1.5Ω
to 4Ω). The R.I.P.S. System detects the actual load
impedance, rather than relying on often inaccurate assumptions
based on a speaker's rated impedance, and adjusts output rail
voltages to deliver consistent output.
RealSink Heat Management: This Slash v3 amplifier features
a real cast-alloy heat sink with vertically-oriented fins, very effective at
dissipating heat from the amplifier via convection and radiation. This design
is achieved through extensive finite-element analysis, resulting in an amplifier
that keeps cool under the most demanding conditions. As an added cosmetic benefit,
the cast-aluminum end-caps replicate half of a heat sink fin so that when two or
more amplifiers are mounted end-to-end, you get a totally seamless custom look.
Advanced Rollback Protection: If a Slash v3 amplifier should
ever reach an unsafe temperature, the Advanced Rollback Protection circuit
power until the amplifier cools down, without turning the music off completely.
Class D Circuitry: JL Audio's Patented Class D output circuit
utilizes a discrete control section and a unique feedback loop design, resulting
in a damping factor greater than 500 at 4Ω (>250 at 2Ω), higher
than most other Class D and Class A/B designs. The benefit is tight, clean bass
reproduction with the efficiency advantage of Class D.
Differential-Balance Inputs: The 600/1v3 features
differential-balanced input architecture to reject noise and ensure
compatibility with a wide variety of source units, including many OEM
systems. Without using a line output converter, you can connect
most OEM or aftermarket source units to the amplifier without creating
any noise or compatibility issues.
Note: You will need a speaker wire to RCA adaptor (item
136XDCLR2S, sold separately) when using a speaker-level input.
Preamp Outputs: The preamp outputs make connecting multiple
amplifiers simple. The 600/1v3 features an independent crossover for the preamp
output, with frequency (40-200 Hz), mode (LP or HP) and slope (12 or 24 dB)
Protection Circuitry With Status Indicator Lights: There are
three status indicator lights on the top of the amplifier:
- Power (Green): green LED indicates the
amplifier is turned on and operating normally
- Thermal (Red): red LED indicates the
amplifier has exceeded its safe operating temperature; the
power output is reduced until the heat sink temperature drops
back to a safe level
- Low Ω (Amber): amber LED indicates
the impedance of the connected speaker(s) is lower than the
optimum impedance range for the amplifier and the power output
is reduced; the amber LED can also indicate a short in the
Note: The only condition that will turn
off the 600/1v3 completely is when the battery voltage drops
below 10 volts.
Infrasonic Filter: Ultra-low frequencies that cannot be reproduced
by a subwoofer do not become sound, but unnecessary oscillations which affect sound by
causing distortion. These frequencies also waste amplifier power and can cause damage
to speakers. Using the infrasonic filter, variable from 15 Hz to 60Hz, removes the
signal below the setting to improve the performance of the speakers by eliminating
harmful distortion. The infrasonic filter can be turned off.
Simplified Gain Setting: The amplifier's R.I.P.S. feature allows
easy gain setup. Because the amplifier always delivers the same output power within
its operational range of load impedance and power supply voltage, the maximum,
unclipped output is predictable. This makes setting input gain very simple, you'll
need a Digital AC Voltmeter (item number
142TK12V, sold separately) and a CD with a sine-wave
bass test tone recorded at 0 dB reference level (item number
sold separately). In addition to the continuously variable rotary gain control,
the Input Voltage switch adjusts the gain range, set to Low (200mV-2V) or High
Auto Turn-On: When using a speaker-level input, the Signal
Sensing switch can be set to On, and the amplifier will turn on and off based on
the presence of the input signal (after approximately 25 seconds with no input
signal the amp will turn off). When in the Signal Sensing circuit is on, the
amplifier's Remote terminal acts as an output to turn on other amplifiers.
Low Pass Crossover: The built-in crossover allows you to adjust
the frequency and filter slope of the amplifier's powered output:
- Mode/Slope Switch:
- Off: crossover is bypassed, useful
when using an external crossover; in this position the
Advanced Bass Control is defeated
- 12 dB: filter slope is 12 dB/octave,
often used when the subwoofer is in the trunk of a sedan
- 24 dB: filter slope is 24 dB/octave
- Frequency: crossover frequency variable
from 40 Hz to 200 Hz; the detented potentiometer allows accurate
Preamp Output Crossover: An independent crossover address what
frequencies the preamp outputs will pass:
- Output Mode:
- Full Range: the preamp output is the
same as the amplifier's input; the signal is not affected
by the Advanced Bass Control
- Amp Filter: the preamp output signal
is the same as the amplifier's powered output, governed by
the Low Pass Crossover and Advanced Bass Control
- Out Filter: the independent crossover
controls affect the preamp output:
- Filter Slope: 12 dB/octave or 24
- Filter Mode: Low Pass or High Pass
- Filter Frequency: crossover frequency
variable from 40 Hz to 200 Hz; the detented potentiometer
allows accurate adjustment
Advanced Bass Controls: The bass control functions on the
- Variable Bass Boost: The amplifier's
variable bass boost features a single band parametric
equalizer with variable Q (0.5 - 4.3), center frequency
(20 Hz to 80 Hz), and boost (0 to +15dB).
- Infrasonic Filter: The 24dB/octave
infrasonic filter has a variable crossover point (15 Hz
to 60 Hz). The infrasonic filter can be turned off.
- Remote Bass Port: The amplifier is equipped
with a connection for an optional wired Remote Bass Control (item number
sold separately), allowing boost control from the front of
Power and Ground: The amplifier's set-screw Power and Ground
connections accept up to 4-gauge wire (4-gauge is recommended if the power wire
is more than 72" long).
Note: The Amplifier is not equipped with
a fuse. An external 60-amp fuse (not included) must be
installed on the power wire. If the system has only this
amp and a wiring kit is used that includes a fuse with a
value other than 60-amps, the original should be replaced
with a 60-amp fuse.
Speaker Output Terminals: The two pair of set-screw speaker
terminals accept 12-gauge to 8-gauge wire. The terminals are internally shorted
together, making it easy to connect two subwoofers.
Remote Turn-On: The set-screw turn-on lead terminal will
accept 12-gauge to 8-gauge wire.
Note: If your headunit does not have a
dedicated remote turn-on output, the amplifier's turn-on
lead can be connected to a switched +12V volt circuit.
Preamp Inputs: The amplifier features one set of
differential-balanced RCA inputs. The amplifier's input level can
be set to Low (200mV-2V RMS) when connecting the amplifier to a low-level
preamp signal or set to High (800mV-8V RMS) when connecting the amplifier
to a high-level speaker signal.
Preamp Outputs: The amplifier also features one set of preamp
outputs so you can send audio to another amplifier in your system. The preamp output
can be full range, or the built-in crossover can be applied.
Note: All inputs, outputs and controls are
located on the front side of the amplifier to make installation
simple and neat.
