    Detail Description
    Detailed Description
    (Manufacturer # PA D4000.4 )

    Features
    The PA D4000.4 amplifier is capable of bridging two full-range channels into a single full range channel with higher output power. For instance, one front and one rear channel will increase the output power from 125W per channel to 400W per channel (for a 4 ohm load). The most common hookups for the PA D4000.4 would be four full-range channels, two full-range channels and a bridged sub, or two bridged subwoofers.
    Super-Eefficient Class D Design
    Runs much cooler than conventional amps.
    Toroidal Transformers
    Help keep the amplifier’s sleek design under 2" tall while ensuring plenty of clean, efficient power
    Protection
    Thermal, DC offset, reverse DC voltage and short circuit protection
    Nickel-plated wire terminals & RCA connectors
    Ensure maximum signal transfer
    Front & rear level controls
    Adjust the gain of the front and rear channels to match the output voltage from your head unit.
    Low-pass & high-pass frequency controls
    Enables you to adjust crossover overlap for better blending of speakers.
    Front & rear BPF, FULL, HPF switches
    Selects full range, high pass filter, or bandpass filter to dial in your speaker blending.
    Channel mode switch (ST/4Ch)
    In the stereo position, the amplifier will send the same signal to front and rear channels
    Stainless steel hardware
    Used throughout, it won’t corrode in humid environments
