Yorkville PX1700 - 850W 2-Channel at 2-Ohm Power Amplifier with XLR and 1/4-inch Inputs in Black Finish

The Yorkville PX1700 is a powerful, reliable two-channel power amplifier designed for small and medium-sized venues that use passive speakers. Whether you're powering a PA system in a club, concert hall, or house of worship, the PX1700 delivers high-quality performance with its 850-watt per channel output at 2Ω. The amplifier can also be bridged to provide an impressive 1700 watts at 4Ω, making it versatile for a wide range of sound reinforcement needs.

The PX1700 uses a Class H design, which optimizes efficiency while maintaining the superior transient response and low distortion of analog systems. It offers a frequency response of 30 Hz to 20 kHz, ensuring clear, accurate sound reproduction across a broad range of frequencies. The use of a toroidal transformer reduces hum and interference, while the amplifier's transparent limiting technology ensures that the sound remains clean even at high output levels.

On the rear panel, the PX1700 offers balanced XLR and 1/4" TRS inputs, as well as binding post and speakON outputs, providing flexible connectivity options for integration into virtually any audio system. The amplifier also features comprehensive protection mechanisms, including short circuit, DC, and thermal protection, to safeguard your speakers and ensure reliable operation in demanding environments. The soft turn-on circuit protects your speakers from sudden power surges during startup, making the PX1700 an excellent choice for both touring and installed systems.

Built with all-steel construction, the PX1700 is rugged and durable, ready to withstand the rigors of both touring and permanent installations. The fan-cooled design ensures optimal operating temperatures, even during long performances. With its efficient and powerful Class H design, along with transparent limiting and protection features, the PX1700 provides exceptional sound quality, reliability, and flexibility, making it the ideal choice for a wide variety of audio applications.
