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.

A: This lens utilizes the Four Thirds Mounting/Connectivity System. If the Black Magic Pocket camera you're interested in is a 4/3 format it should work well. Otherwise an adaptor would be required and probably not your best choice. This lens is not considered a cinematographic lens although it is an excellent performing lens at a very reasonable price. I use it on a Panasonic 4/3 mirrorless camera with wonderful results. Good luck!
