Overview

QSC SPA Series SPA4-100 4 Channel EnergyStar 70V/100V/8 Ohm/4 Ohm Amplifier

QSC SPA Series SPA4-100 4 Channel EnergyStar 70V/100V/8 Ohm/4 Ohm Amplifier

The QSC SPA Series amplifiers are engineered to deliver reliable audio amplification in a compact form factor. The SPA4-100's four-channel design provide up to 100 watts per channel into both 4Ω and 8Ω loads, ensuring consistent performance across different speaker configurations. For applications requiring higher power, this series offers bridgeable outputs, delivering up to 200 watts into low impedance and up to 175 watts into 70V or 100V systems, making it versatile for both low-Z and high-Z applications. ​

One of the standout features of the SPA Series is its EnergyStar qualification, attributed to its efficient Class-D amplifier design. This efficiency not only conserves energy but also reduces operational costs, aligning with modern sustainability goals. The amplifiers incorporate Auto-Ramp circuitry, which ensures quiet and rapid power-up from standby when a signal is detected and seamless power-down after 25 minutes of inactivity. This feature significantly reduces power consumption without compromising performance, making it ideal for environments where energy efficiency is paramount.

Installation flexibility is another key advantage of the SPA Series. Their rack-mountable 1U, half-rack width enclosures allow for efficient use of space in equipment racks. Additionally, the amplifiers come with unique mounting hardware, enabling easy under-table and wall-mounting options. This adaptability ensures that the SPA Series can be seamlessly integrated into a variety of settings, from corporate meeting rooms to educational facilities, providing high-quality audio amplification without imposing on aesthetic or spatial considerations. ​

The QSC SPA Series amplifiers combine advanced design with robust construction to deliver high-quality sound in any environment. Their versatility, durability, and superior audio performance make them an excellent choice for enhancing your audio experience.
