Description
The LOC-22 is a fully active 2-channel speaker level to line output converter from JL Audio. This unique item on the market is a top seller and a masterpiece of engineer Bruce Macmillan. The LOC-22 impresses with its fully regulated, switchable MOSFET power supply and pure analog circuit design that delivers a smooth frequency response at any signal level. With its ability to combat induced cable noise and easily handle powerful factory amplifier outputs, this high-low adapter is specifically designed for applications that require conversion of factory audio signals for use with aftermarket amplifiers and signal processors. The LOC-22 also offers automatic turn-on methods and is ideal for full range or low frequency applications. With its analog RCA output jacks and easy adjustment of output levels, it is the perfect addition to your audio system.
Features
- Fully active two-channel speaker level line output converter with automatic switch-on
- Designed by JL Audio Sr. engineer Bruce Macmillan, the LoC-22 is a two-channel active processor designed for applications requiring the conversion of factory audio signals for use with aftermarket amplifiers and signal processors.
- The LoC-22 uses a fully regulated, switching MOSFET power supply and an all-analog circuit design to deliver a flat frequency response at any signal level (3 Hz - 32 kHz, +0, -1dB) without altering bass response at high levels, as is the case with many passive line output converters.
- Designed to combat induced cable noise, the LoC-22 features a differential balanced input architecture that makes it compatible with virtually any analog audio signal.
- The LoC-22 can record up to 40 V RMS per channel (equivalent to 400 W into 4 ohms) and easily handles the most powerful factory amplifier outputs.
- A built-in dual-range input load switch enables compatibility with most factory amplifiers that use impedance measurement to mute channels.
- Ideal for full range or low frequency applications, the LoC-22 is equipped with a pair of line level analog RCA output jacks (up to 8 V RMS) for feeding audio signals into your aftermarket system. The analog outputs are compatible with most types of signal processors or aftermarket amplifiers.
- Adjusting the output levels is super simple and easy thanks to a specially calibrated, integrated clipping display that works with test tones or music.
- The LoC-22 offers two automatic turn-on methods (DC offset detection or signal detection) and provides a positive 12V turn-on output for activating aftermarket amplifiers or other downstream electronics.
