The D8250 and D8120 are professional eight channels power amplifiers capable of delivering a power of 500 Watt and 120 Watt at 4 Ohm loads connect to its 8 output channels. On the 16 channels D1660 amplifier, it can deliver a power of 60W at 4 Ohm loads. The perfect solution for installed Multi-Zone audio distribution systems with 8 to 16 zones with great simplicity in use and installation.

All done in double rack space, steel 19”rack mount housing. Inputs and outputs are all performed with 3-pin Euro-Terminal block connectors, allowing balanced input signals. Each individual channel is fitted with a separate gain control potentiometer that sets Stereo/Bridge & Parallel via a switch to avoid cable clutter when distributing the input signal.

Built-in multipurpose protection circuit protecting against DC malfunction, short circuit, overheating, overload, and limits the signal when necessary.
