SylphAudio D400M Amplifier Module

The versatile Sylph Audio D400M Class D amplifier module benefits from a 2Ω load capacity, enabling it to effortlessly handle demanding loudspeakers while delivering high-quality sound reproduction with a very low level of distortion.

The D400M features a connector on its input stage for easy replacement of the OPA. This makes it easy to customize the module's output. What's more, the Sylph Audio D400M offers both unbalanced and balanced inputs, making it suitable for all audio sources. The buffer circuit's independent power supply stage eliminates the need for coupling capacitors for purer sound. A TVS diode protects the module against power surges and accidental polarity reversal* for increased durability. Integrated voltage management circuitry ensures silent on-off transitions, avoiding annoying clicks or pops for a pleasant audio experience.

What's more, the D400M is equipped with an ATS heatsink for the TPA3255, keeping the temperature at a suitable level, even when used in demanding configurations. Finally, configurations using multiple modules are simplified thanks to jumpers for setting the slave mode, and OSC IOM/IOP solder pads accessible under the PCB for effortless expansion of the number of audio channels.

Recommended power supply :

• SMPS 51V power supply, 300W or more per module
• Do not use feeders with separate rails
• Use 34V DC for unregulated linear power supplies
