Further Information

Overview: 

Today we bring you the ZoneMaster Model 1250. This 12-channel distribution amplifier is built to deliver great sound throughout multiple rooms, with each channel providing 50 watts of power. Unlike typical distribution amps, the ZoneMaster 1250 combines flexibility and power, making it a solid choice for both general distribution and more demanding audio setups. With two "Bus" inputs, the ZoneMaster 1250 lets you route audio to any of its channels, and you can also use direct inputs for each one. It even supports speaker-level input via the second Bus channel, adding to its versatility. Each channel has dual Phoenix-style speaker outputs that can handle up to 12-gauge wire, allowing you to connect up to 24 speakers across your home. Plus, with stability into 2 ohms, this amplifier can handle a wide range of speaker configurations. The 1250 also features a Class A/B input stage and a Class D power stage, ensuring efficient operation while still delivering high-quality sound. It comes with independent 12-volt triggers for each zone and a global trigger, making it easy to integrate into your home automation system. For even more flexibility, you can bridge two channels to get 160 watts into 8 ohms or 200 watts into 6 ohms—perfect for boosting your home theater setup, especially if you’re adding speakers for Dolby Atmos, DTS UHD, or AURO-3D.
