California's AV Power Management Specialist
Panamax was founded in Petaluma, California in 1975, establishing itself as a specialist in audio/video power management — a more demanding application than general-purpose surge protection because audio and video equipment is sensitive to both voltage spikes and the electrical noise that degrades signal quality. The company has remained in Petaluma through five decades of product development, with manufacturing centered in the US.
The distinction between Panamax and general-purpose surge protectors is meaningful for audio/video applications: Panamax products include noise filtration circuitry that removes the electromagnetic interference that travels on power lines and contaminates audio signals. For audiophiles, recording professionals, and home theater enthusiasts, this matters — a power conditioner can measurably improve noise floor performance in high-resolution audio systems.
Power Conditioning for Audio/Video Systems
Panamax's product line includes the MR series home theater power managers and the M series surge protectors and power conditioners. The MR5100 and MR4300 are full-featured power managers with automatic voltage monitoring and protection, filtration banks for equipment with different power requirements, and the circuitry to handle high-current amplifier loads without restricting dynamic headroom.
For home theater and audio system builders who want to protect equipment investments and potentially improve system noise performance, Panamax provides the power foundation that high-end equipment manufacturers recommend. The Petaluma production and 50-year audio/video specialization give Panamax credibility in a product category where brand engineering heritage matters.
