SPA-Q 60x4

Four-Channel Network Amplifier for the Q-SYS Platform

The Q-SYS SPA-Qf 60x4 network amplifier continues the Q-SYS Platform evolution of pairing centralized Core OS processing with expanding endpoint utility. With available GPIO for control, two flex channels (either mic/line inputs or line outputs), and 60 W per channel, the Q-SYS SPA-Qf 60x4 (four-channel) provides the utility to centralize your processor’s connectivity across more spaces, all within a trusted native Q-SYS network amplifier.
