Digital Amplifier 300W x 2, Stereo Class D, 2.0/2.1 Channel HiFi Sound, TPA3255 Chip, RCA Input, PRE OUT, Black, for Home Audio
You already have the maximum available quantity in your cart.
The Class D digital amplifier is designed to drive passive speakers with an impedance of 4–8 Ohm and offers output power of 300 W + 300 W at a load of 4 Ohm (10 % THD+N). The heart of the amplifier is a TPA3255 chip complemented by a pair of NE5532 operational amplifiers, which can be replaced with other types according to personal preferences. The stereo amplifier achieves a signal-to-noise ratio of 103 dB and distortion of 0.05 %, with a frequency response covering the entire audible range of 20 to 20,000 Hz. The audio signal connects via RCA input, allowing the amplifier to work with mobile phones, tablets, computers, MP3 players, and televisions. The PRE OUT output allows connection of an active subwoofer to create a 2.1 system, or to connect another amplifier in bridge mode to power a second pair of passive speakers. On the front panel of the black body, you will find a power switch with an indicator and a volume control knob with a scale, while the rear panel houses screw terminals for the left and right channels, RCA input, PRE OUT connector, and power connector.

Contents of the package
- 1 pcs amplifier
- 1 pcs DC 32 V 5 A power supply (optional)
The amplifier can handle classic stereo configuration 2.0 as well as expansion to 2.1 using an external active subwoofer connected to the PRE OUT connector. The volume control on the front panel also controls the signal level at the PRE OUT output, allowing you to manage the entire system with one knob. In bridge mode, a second amplifier can be connected via PRE OUT to power a larger room or two zones simultaneously. Thanks to the RCA input, it connects with televisions, computers, laptops, and desktop players without the need for additional adapters. The option to replace operational amplifiers allows for later adjustments to the sound output without interfering with the rest of the setup. For operation, a DC 24 to 48 V power adapter with a current of at least 5 A is required, which can be chosen according to the desired power and the speakers used.
