• 2.5 mm Allen-wrench
• 3 mm Allen-wrench
General Features:
• 12-decibel/octave filter with selectable high, low or defeat (off) modes
• selectable input voltage: low (200 mv to 2-volt rms) to high (800 mv to 8-volt rms)
• 3 turn-on options: +12-volt remote wire, signal sensing or dc offset
• onboard led clipping indicator simplifies level setting
• signal routing flexibility with 2-, 4- or 6-channel input mode
The Amp that does it all
Power your entire system with this 5-channel system amplifier that combines a 4-channel full-range and monoblock subwoofer amplifier in one single, easy-to-install package. A generous feature set adds even more value.
Efficient Class D Design
Small size, minimal heat and lots of power — Class-D amplifier design offers significant advantages. And our NexD™ switching technology adds even more, using enhanced pulse width modulation techniques to boost the amplifier’s bandwidth while minimizing distortion and improving efficiency.
Total System Power
The 4-channel amplifier churns out 400 watts of total power — 100 watts from each of its 4 channels, perfect for door speakers. A 300-watt mono channel offers plenty of power for a 10- or 12-inch subwoofer.
Premium-Level Signal Processing
This JD series amplifier’s signal processing features include high- or low-pass 12 decibel/octave filters for each channel pair, with continuously variable frequency selection from 50–500 Hz.
LED Clipping Indicator Rings
An LED clipping indicator ring that surrounds each input level potentiometer lets you quickly set your amplifier’s input sensitivity, without the need for additional test equipment.
Build Strong and Smart
Featuring a sleek industrial design with molded end caps and an aluminum extruded chassis, the JD series’ power indicator and protection LED indicators shine from behind a simple black logo bar on the top surface of the amplifier.
