PSI Audio A 14 M Studio Monitor - Single

Absolute Precision. Impossibly Compact.

The A 14 M Studio is the definitive audio reference for professionals working in limited spaces. It is a compact instrument of the highest precision, engineered to deliver the highest possible Sound Pressure Level and the broadest bandwidth for its size. This monitor is the solution for small studios, mobile setups, or as a component in a multi-channel immersive system where accuracy cannot be compromised. Its 100% analog signal path ensures that what you hear is a pure, unadulterated reproduction of your source, providing a "set-and-forget" reference tool with its calibration-focused rear-panel level control.

Compensated Phase Response (CPR): A Holographic Stereo Image
The "perfect stereo image" of the A 14 M Studio is the direct result of the proprietary Compensated Phase Response (CPR) system. This all-analogue circuitry corrects for phase shifts by employing several all-pass filters, ensuring that all frequencies—from the delicate highs of the handmade tweeter to the upper bass—arrive at the listener's ear simultaneously. This technology allows such a compact monitor to project a soundstage with a depth, width, and pinpoint focus that defies its physical dimensions, allowing you to mix with confidence.

Adaptive Output Impedance (AOI): Uncolored Transients
In a compact monitor, controlling driver resonance is paramount. The A 14 M Studio features the Adaptive Output Impedance (AOI) system, a sophisticated analog feedback loop that actively monitors the woofer's movement. By detecting membrane motion and instantly adjusting the amplifier's output impedance, AOI provides a filtered counter-reaction that eliminates material resonances. The result is a stunningly accurate, flat frequency response with bass and midrange transients that are fast, tight, and completely free of the "boxiness" or port-related smearing that plagues other small monitors.

100% Analogue, Class A/B Power
The A 14 M Studio is a tool of pure fidelity. Its "100% Analog – No DSP"  design ensures a signal path with zero digital conversion, zero artifacts, and absolutely no latency. This pure signal is fed to a powerful Class A/B bi-amplification system, which is individually calibrated for each specific unit in an anechoic chamber. This combination guarantees that the engineer hears the instantaneous, unadulterated analog signal—a critical requirement for timing-sensitive tasks.
