Boulder has introduced its newest product, the 1151 mono amplifier, which merges sophisticated engineering with a compact design. This amplifier is engineered to manage even the most demanding acoustic systems, incorporating state-of-the-art technology for exceptional performance and dependability.
The 1151 offers substantial power output, rated at 350 watts per channel at 8 ohms, 600 watts at 4 ohms, and an impressive 750 watts at 2 ohms. Despite its powerful performance, the amplifier boasts a sleek design that matches the footprint of Boulder’s 1110 preamplifier, facilitating seamless integration and optimal space utilization. This compatibility also extends to its power supply, allowing users to power both devices with a single power cord for a tidier setup.
Boulder 1151 – 750W mono amplifier
A key feature of the 1151 is its advanced protection circuit. This system promptly disables the amplifier’s output stage in the event of a short circuit in the speaker cables or a malfunction in the connected equipment, protecting the device and ensuring user safety. Furthermore, this circuit enhances the amplifier’s capacity to manage higher peak output power.
The automatic bias circuit has been redesigned to enhance its performance. This enhanced system accurately manages and stabilizes the amplifier’s bias levels, eliminating the need for manual adjustments and streamlining both setup and maintenance processes.
The amplifier is capable of delivering 350 watts per channel into 8 ohms, 600 ohms into 4 ohms, and 750 ohms into 2 ohms.
Internally, the 1151 features a robust output stage that includes 40 output transistors and 12 power capacitors. This arrangement guarantees reliable and stable power delivery across a range of loads, ensuring optimal performance for various speaker systems.
Combining power, protection, and precision, the Boulder 1151 mono amplifier presents a flexible solution for audiophiles who desire high-quality sound reproduction within a compact and thoughtfully engineered framework.
