1x JL Audio LoC-22: Fully Active, Two-Channel Speaker Level to Line Output Converter with Auto Turn-On - (LOC-22)
JL Audio LoC-22
Fully Active, Two-Channel Speaker Level to Line Output Converter with Auto Turn-On
Fully Active, Two-Channel Speaker Level to Line Output Converter with Auto Turn-On
Designed by JL Audio Sr. Engineer Bruce Macmillan, the LoC-22 is an active two-channel processor engineered for applications requiring the attenuation of factory audio signals for use with aftermarket amplifiers and signal processors.
The LoC-22 utilizes a fully regulated, switching MOSFET power supply and an all-analog circuit design to deliver flat frequency response, at any signal level (3 Hz – 32 kHz, +0, -1dB), without altering bass response at high levels, like many passive line output converters do.
Engineered to combat induced cable noise, the LoC-22 features a differential-balanced input architecture making it compatible with virtually any analog audio signal. Capable of accepting up to 40V RMS per channel (equivalent to 400W @ 4 ohms), the LoC-22 easily handles the most powerful factory amplifier outputs. An onboard dual-range input load switch allows compatibility with most factory amplifiers that employ impedance sensing to mute channels.
Ideal for full-range or low-frequency applications, the LoC-22 is equipped with a pair of analog RCA-type, line-level output jacks (up to 8V RMS) to feed audio signals to your aftermarket system. Analog outputs are compatible with most types of aftermarket signal processors or amplifiers. Setting output levels is super simple and easy, thanks to a specially calibrated, onboard clipping indicator that works with test tones or music. The LoC-22 offers two automatic turn-on methods (DC-Offset Sensing or Signal Sensing) and provides a positive 12V turn-on output to activate aftermarket amplifiers or other downstream electronics.
The LoC-22 includes the following features:
- Fully active, all analog circuit design by Bruce Macmillan, handles powerful factory amplifier outputs, up to 40 volts per channel
- Differential-balanced input architecture offers noise rejection and compatibility with most analog outputs from OEM source units and amplifiers
- Dual range input load switch (20 kΩ/Normal, 60 Ω/Low Z, thermally protected) for maximum compatibility with OEM amplifiers
- One stereo pair of crystal-clear, line-level RCA output jacks (up to 8V RMS)
- Automatic turn-on via DC-Offset or Signal-Sensing
- A dedicated 12V remote turn-on output (maximum 100 mA) to activate aftermarket signal processors or amplifiers
- Onboard LED clipping indicator makes output level setting quick & easy
- Ultra-compact chassis design fits into just about any installation location!

1x JL Audio XDM600/1 XDM Series Monoblock Class-D Car/Marine Subwoofer Amplifier, 600 W - (XDM600/1)
JL Audio XDM600/1 Monoblock Class D Car/Marine Subwoofer Amplifier, 600 W x 1 @ 2 Ω / 400 W x 1 @ 4 Ω - 14.4V
This potent monoblock amplifier employs JL Audio's high-speed NexD™ switching design to achieve unprecedented efficiency and amazing power output from a very compact chassis. Don't let its small size fool you, though... the XDM/600/1 generates serious subwoofer power, delivering a full 600 W of continuous power into a 2 ohm load (14.4V, 1% THD).
Designed for car or boat installations, the XDM600/1 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades.
Targeted specifically for subwoofer applications, the XDM600/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), the amplifier's level can be adjusted directly from the driver's seat or captain’s chair.
Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.
