2pcs SylphAudio-D400M P05 TPA3255 PBTL Mono RTR (Low Gain)

$190.00 USD - $238.00 USD Coming Soon

TPA3255 based, mono class-D amplifier with 2 ohms load capability.

Replaceable DIP8 socket opamp buffer (default opamp is JRC4565D). With low gain configuration which requires a preamp that can output 9Vrms.

The analog input can accept full balanced or single ended signals which can be configured by onboard jumpers. The output is 1 channel, mono PBTL configuration.

A split supply is used in the opamp buffer in order to delete the frontend input coupling caps in the buffer stage. The positive and negative rails for opamp supply are being generated on-board with post regulators.

Includes TVS diode for power supply surge protection, and will normally short out when an accidental reverse polarity is applied.

Solder jumper for slave setting, OSC IOM/IOP pads are under the PCB for multi-device configuration. (SLAA787)

All RTR modules are already tested before shipping.
