Boulder 1162 Stereo Amp – a Mighty Power Amplifier
14.02.2025 11:03 | ~1 minute read
The American manufacturer of High-End audio equipment, Boulder, has introduced a new stereo power amplifier, the Boulder 1162. The model offers 2 x 300 watts of power into 8 ohm speakers and a staggering 2 x 900 watts into 4 ohm load.
As is typical for this line, the Boulder 1162 is housed in a recognizable case with a machine front panel depicts the topography of Flagstaff Mountain near Boulder, Colorado. The amplifier uses the proprietary Class-A Smart Current Biasing Circuit topology, and the power supply (dual power transformers are DC filtered and enclosed a welded steel case) with a 32 Amp IEC pre-terminated power cord (supplied in order).
Boulder 1162 uses newly developed protection circuitry. There is also an additional Ethernet-enabled supervisor circuitry on board, which monitors amp and protection systems. The Boulder 1162 weighs 61.2 kg.
