QSC SPA Overview

The highly flexible QSC SPA4-100 4-Channel Power Amplifier is an advanced Class-D amplifier with Energy Star rated efficiency well suited for smaller installations including meeting rooms or BGM zones. The convection cooled amplifier is designed to conserve energy. An auto-ramp circuit ensures quiet and fast power up from standby when a signal is present and seamless power-down following 25 minutes of inactivity, dramatically reducing power consumption.

The rear panel utilizes Euroblock connectors for inputs and outputs as well as remote inputs. Each channel of the SPA4 provides 100W of power, while the bridge mode provides 200W into 4 or 8 ohms and 175W into 70/100V.

  • Provides up to 100W per channel into Low-Z loads at 4 and 8 Ohms
  • Energy Star qualified SPA Series employ an efficient class-D design to conserve energy and reduce operational cost
  • Delivers up to 175W into 70/100V when bridged
  • Rack-mountable 1 RU, half-rack width enclosure—the SPA Series can be mounted in 1 RU, 1/2 rack space, and their clever joining brackets enable easy under table and wall mounting
