Looking for a good amplifier module?
The UCD amplifiers of the ST range offer an unbeatable quality / power / price ratio!
Available in 3 versions: 180W, 400W and 700W they can be adapted to any Hi-fi or Professional use.
The UCD400ST is a Class D digital amplifier designed for a wide range of audio applications.
Its main characteristics are an absolutely flat response curve and independent of output impedance, low distortion rate as well as low sensitivity to noise and EMI.
The modulation is based on a controlled phase-change oscillator with a low feedback rate.
