Product Description
The AudioSource AD508 Digital Multi-Zone Power Amplifier is the ultimate solution for residential and commercial multi-room audio systems. Engineered to power 8 independent channels (4 stereo zones), the AD508 offers rock-solid Class D digital efficiency with 65W per channel at 8 ohms, 100W at 4 ohms, or delivering up to 200W bridged pair into 8 ohms.
Each channel can select between a dedicated Line In, Bus 1, or Bus 2 input. A dedicated Optical input allows you to connect digital sources in PCM stereo format. Two master-level Bus volume controls, plus treble and bass for each Bus, allow installers to optimize performance room-by-room.
AudioSource AD508 system control is flexible with three power modes: Auto-On (signal sensing), 12V trigger, or always-on. Each zone includes status LEDs, individual level knobs, and bridge mode switches. A front-panel power switch with LED lets you know when the amp is active or in standby. The included IR remote allows convenient volume adjustments for Bus 1 and 2. The AD508 offers scalability, control, and reliability in a rack-mountable chassis.
