JL Audio JD250/1

Discover the JD250/1, a 1-channel amplifier from JL Audio. This particular model is a 250W monoblock Class D subwoofer amplifier - designed to generate 250 watts at 2 ohms. With the proprietary NexD™ The JD250/1 offers excellent efficiency and ultra-low distortion thanks to JL Audio's switching technology. In addition, the amplifier features practical controls and numerous signal processing functions, including a variable bass boost EQ. A special feature of this amplifier is the integrated LED clamp indicator ring, which allows precise adjustment of the input sensitivity without the need for special equipment. The JD250/1 meets all the requirements for an efficient subwoofer supply system.

• Monoblock subwoofer amplifier in Class D, 250 W x 1 @ 2 Ω / 150 W x 1 @ 4 Ω - 14.4V
  
• Designed to produce 250 watts into 2 ohms (14.4V, 1% THD), the JD250/1 amplifier is a great 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 ultra-low distortion.
  
• The JD250/1's controls are located on the input panel, while the power and speaker connections are at the opposite end of the extruded aluminum chassis.
• Signal processing features include a 12 dB/octave low-pass filter with continuous frequency selection from 50-500 Hz and a variable bass boost EQ.
• Differentially balanced dual-range inputs are also available, which can accommodate line and speaker level signals.
• Automatic power-on (via signal sensing or DC offset sensing) is standard, along with a number of preamp outputs so that signals can be easily routed to another amplifier.
  
• The JD250/1 also features an integrated LED clamp indicator ring that surrounds the input sensitivity control. This useful feature allows you to quickly and precisely adjust the amplifier's input sensitivity 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.
