Boulder 1152 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.
The redesigned and modernized automatic bias circuit accurately stabilizes the operating parameters. The Boulder 1152 output stage uses 40 transistors and 12 power capacitors. Thus, it was possible to achieve stable output power even with a complex load.
