Features

• Monoblock subwoofer amplifier in Class D, 500 W x 1 @ 2 Ω / 250 W x 1 @ 4 Ω - 14.4V
  
• The JD500/1 amplifier is designed to produce a whopping 500 watts into 2 ohms (14.4 V, 1% THD) and is an excellent solution for powering subwoofers in a cost-conscious system.
• JL's proprietary NexD™ switching technology delivers large amounts of real output power with excellent efficiency and extremely low distortion.
  
• The controls of the JD500/1 are located on the input panel, while the power and speaker connections are located at the opposite end of the extruded aluminum housing.
• The signal processing functions include a 12 dB/octave low-pass filter with infinitely variable frequency selection from 50-500 Hz and a variable bass boost EQ.
• Differential balanced dual-range inputs are also available to accommodate line and speaker level signals.
  Automatic power-on function (via signal sampling or DC offset sampling) is standard, along with a range of preamp outputs so you can easily route signals to another amplifier.
  
• The JD500/1 is also equipped with an integrated LED clamp indicator ring surrounding the input sensitivity control. This useful feature allows you to quickly and precisely adjust the input sensitivity of the amplifier without the need for special equipment.
  
• With an additional RBC-1 remote control (sold separately), you can control the subwoofer level from the driver's seat.
