What It Is

PS Engineering Inc. is an avionics manufacturer with a 40-year history, specializing in audio control systems and intercom equipment for general aviation, business aviation, and special-mission aircraft such as forestry service, search and rescue, and medical evacuation. Its core products include various PMA-series audio panels and PM-series intercom systems.

Core Features (by Dimension)

• Channels: Supports multi-channel audio routing, including aviation VHF radio transmission/reception, crew intercom (ICS), Bluetooth audio streaming, and entertainment audio input. It also features SoftMute™ technology, which automatically mutes music during communications.
• Regional coverage: The text mentions a network of 350 dealers, with business coverage across the global aviation market.
• Deliverability and performance: Audio clarity is highly dependent on installation quality. The system uses isolated power, digital, and signal grounds to resist electrical noise, but if shielding and grounding are not handled properly, it is highly susceptible to airframe RFI interference and noise.
• API and integrations: At the hardware level, it supports integration with mainstream avionics such as Dynon SkyView HDX, and provides Bluetooth pairing as well as an internal recording system (IRS).
• Compliance: Products strictly comply with FAA TSO (TSO C50c) and RTCA DO-214 certification standards. Installation of non-TSO-certified products requires FAA FSDO approval.

Pricing

The text does not disclose specific hardware pricing and appears to follow a typical hardware sales model. Notably, its factory warranty terms are strict: coverage is limited to installations by authorized dealers or Plug N' Play replacements using its custom wiring harnesses.

Pros and Cons

Pros: 40 years of industry experience; a broad and highly segmented product line; support for Bluetooth and multi-source entertainment inputs; extremely detailed FAQs and technical support; compliant with strict aviation airworthiness certifications.
Cons: Very high installation requirements and must be handled by professional avionics shops; electrical compatibility issues with some consumer devices such as older Motorola phones and high-power car audio systems; background radio noise in older aircraft cannot be fundamentally resolved simply by upgrading the intercom.

Who It’s For

Suitable for general aviation aircraft owners who need to upgrade or replace aircraft audio control panels, business jet operators, and special-mission flight departments that require customized communication solutions. Authorized avionics installers are also an important target service audience.
