JL Audio Monoblock Class D Car/Marine Subwoofer Amplifier - 010-03112-00

JL Audio 98677 Monoblock Class D Car/Marine Subwoofer Amplifier

This monoblock subwoofer powerhouse employs our high-speed NexD™ switching technology to achieve unprecedented efficiency and amazing power output from a very compact chassis. The XDM1000/1 generates up to 1000 W of continuous power into a 2 ohm load (14.4V, 1% THD), making it a great choice to drive higher power subwoofer systems.

Designed for car or boat installations, the XDM1000/1 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.

Intended specifically for subwoofer applications, the XDM1000/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz and a defeatable infrasonic filter (30 Hz, 24 dB/oct.). 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.

Features

• NexD™ Switching Technology
  NexD™ amplifier technologies produce exceptional audio quality, unsurpassed total efficiency and high power from very compact amplifier designs.
• Advanced Rollback Protection
  JL Audio's exclusive Advanced Rollback Protection circuit monitors the amplifier's thermal condition and adjusts amplifier operation to eliminate annoying amplifier shut-down events.
• Differential-Balanced Inputs
  JL Audio’s Differential-Balanced Inputs are engineered to combat induced cable noise, which is a common problem in car and marine audio installations. This technology allows for the use of conventional RCA cables, while delivering many of the benefits of a true balanced connection and accepting a wide range of input signal levels.
