The Boulder 2150 is a Class A single—channel power amplifier with up to 4,000 watts for any load (2-8 ohms). Inside there are 80 output transistors, three toroidal transformers and 48 capacitors for clear, distortion-free sound. The device is equipped with a fully balanced circuit and an XLR connector for input, two sets of terminals for output, supports Ethernet control and a 12V trigger.
Boulder 1151 is capable of driving almost any speaker system on the market. The amplifier is capable of delivering 350 W per channel at 8 Ohm, 600 Ohm at 4 Ohm and 750 Ohm at 2 Ohm load.
