( Brand: Phase Linear ), ( Model: PL400 ), ( Type: Power Amplifier )
The PL400 Phase Linear 400W Power Amplifier is a high-performance audio component designed for audiophiles and music enthusiasts seeking a truly immersive listening experience. This amplifier is a testament to Phase Linear's commitment to delivering exceptional sound quality and power.
The PL400 is a class AB amplifier, which means it combines the best elements of both class A and class B amplifiers. This design ensures minimal distortion, even at high power levels, while also maintaining excellent efficiency. The amplifier is rated at 400 watts per channel into 8 ohms, making it capable of driving a wide range of speakers with ease.
The PL400's output stage employs Phase Linear's unique Direct Coupled Differential (DCD) circuit topology. This design eliminates the need for output transformers, resulting in lower distortion, better dynamics, and improved frequency response. The amplifier's input stage uses a cascode configuration, which provides a high input impedance, ensuring that it can drive a wide range of sources without loading them down.
The PL400 is built using high-quality components, including hand-selected capacitors, metal-oxide resistors, and MOSFET power devices. These components are mounted on a large, heavy-duty aluminum heatsink, which ensures that the amplifier stays cool even under heavy load. The amplifier's chassis is made of thick, high-quality steel, and it is finished in a handsome black powder coat.
The PL400's front panel is simple and uncluttered, with only a few controls. There are separate gain controls for the left and right channels, as well as a balance control to ensure that the stereo image is perfectly balanced. The amplifier also features a power switch and a set of LED indicators to show the status of the various functions.
In terms of connectivity, the PL400 features a pair of high-quality gold-plated RCA jacks for its line-level inputs, as well as a set of speaker binding posts for output. The amplifier also includes a 12V trigger input, which allows it to be controlled by an external source, such as a preamplifier or a home automation system.
In conclusion, the PL400 Phase Linear 400W Power Amplifier is a high-performance audio component that delivers exceptional sound quality and power. Its unique Direct Coupled Differential circuit topology, high-quality components, and robust construction make it an excellent choice for serious audiophiles who demand the best from their audio systems.
