For three decades, QSC amplifiers have set the standard for cinema sound. The DCA Series is no exception. Built on a rugged tour-grade chassis, DCA amps deliver heavyweight power in a light 2RU package. All models are equipped with our innovative DataPort interface, which makes hook-up fast, enables control and monitoring via QSC processors, and supports a range of useful accessories. All are safeguarded by protective circuitry that keeps them going strong over the long haul. And all are THX® approved. With proven performance you can depend on every day, it’s no wonder that QSC is the world leader in cinema amplifiers.
The DataPort advantage
The contrast between the DCA Series and competing cinema amplifiers starts with our pioneering DataPort interface. Using a standard VGA-style connector that simplifies wiring and speeds installation, DataPort provides single-cable integration of DCAs with DCP, DXP, BASISTM, and DCM processors. Creating a smart, centrally controlled system that goes beyond simple audio connections, DataPort enables DSP crossovers, speaker-specific EQ, and monitoring and control of amplifier and loudspeaker functions. DataPort also accepts and powers analog accessory devices (XC-3, SF-3, and LF-3) that expand the capabilities of both DCA and ISA 2-channel amplifiers.
A single QSC DataPort connection includes two channels of audio, output voltage monitoring (VMON), current monitoring (IMON), clip/protect monitoring, and thermal monitoring. DataPort also enables AC standby control and provides a 15 volt DC power supply for rear-panel accessories.
Built to last
QSC amplifiers are renowned for extended life because QSC builds them for long-term reliability. In addition to durable construction, DCA Series amplifiers feature today’s best available amplifier protection technology:
A model for every role
The DCA Series includes both 2-channel and 4-channel models. Some are designed with specific cinema applications in mind, while others are equally at home in varied roles:
Versatile performers — Depending on room size and loudspeaker power requirements, the DCA 1622,
DCA 2422, and DCA 3032 are great choices wherever they’re needed: screen channels, subwoofers, or surrounds.
