Audiophiles have known for years that the power coming through the AC line is full of interference and line disturbances that degrade audio reproduction. Dirty power is also caused by radiated high frequency signals, such as those coming from broadcast stations, or even your own video and digital components. You only have to see the interference from a motor or hairdryer to see and hear its effects. With today's digital circuitry and especially with digital video, polluted AC power can cause poor quality sound and picture. The detrimental effects of dirty power cannot be removed by ordinary surge protectors. Monster's Clean Power Circuitry Stage 2 v.2.1 filters are the latest in AC power line noise rejection. Isolation of audio and video equipment is provided for improved component-generated noise rejection. The result is the best possible sound and picture from your components. You'll enjoy a more natural sound with increased dynamic range as well as the most vivid image possible. The Monster Power HTS 2600 MKII protects the sensitive Home Theater components that can be easily damaged from the surges and spikes common with AC power. The problem is even worse if you live in an area plagued by lightning or power blackouts. Extremely high voltages can travel through the power line, seriously damaging or even destroying your components. Monster Tri Mode circuitry suppresses surges and Monster T2 utilizes a microprocessor to automatically disconnect your components - only reconnecting them when the levels are safe.
