Big Power, Small Size

Pioneer's GM-DX871 brings a striking combination of power and compactness. Here's what sets it apart:

• Highly Efficient Class-D Technology: The GM-DX871 boasts Class-D digital amplification technology, which is significantly more efficient than traditional Class-AB amplifiers. This means it can deliver impressive power output while being 50% smaller in size compared to its Class-AB counterparts.
• 800 Watts RMS: This mono subwoofer amplifier can produce up to 800 watts RMS to fuel your subwoofer. The result is powerful, deep bass that adds a robust and heavy beat to your favorite music.
• Cool Operation: Despite its impressive power, this amplifier runs as cool as it looks, thanks to the highly efficient Class-D technology. It also features a small chassis that fits into various spaces, making it versatile and easy to install.

Variable Low-Pass Filter

To fine-tune your audio experience, the GM-DX871 comes equipped with a variable Low-Pass Filter (LPF) with an adjustable range from 40 Hz to 240 Hz. This feature allows you to tailor the audio frequency to match your subwoofer's characteristics and your personal listening preferences. It ensures that your bass sounds exactly the way you want it.

Protection Control System (PCS)

Pioneer's Protection Control System (PCS) is a significant addition to this amplifier. It continuously monitors various factors, including input voltage, current consumption, and operating temperature. Based on this real-time data, the amplifier adjusts its output to ensure operational stability during extended listening sessions or when it's installed in high-temperature environments. This means your amplifier can deliver consistent performance, no matter the conditions.

Improved Circuit Design

The GM-DX871 features an improved circuit design with the Protection Control System. This advanced technology prevents circuit shutdown by monitoring the amplifier's internal temperature and moderating the input level accordingly. The result is stable and durable circuitry that minimizes the risk of high input power, even with a 1-ohm connection, providing flexibility for connecting multiple subwoofers to your system.

Turn Up the Bass

Every Pioneer Class-D amplifier includes a wired bass boost remote control. This feature allows you to make real-time adjustments to the bass levels, giving you the freedom to fine-tune the listening experience based on the characteristics of your music and your personal preferences.
