TDA1541A D/A converter: The heart of the CD630. This legendary 16-bit dual converter chip is still considered by audiophiles to be one of the most musical and "analog" digital-to-analog converters ever built. It delivers a warm, spatial sound without digital harshness. To ensure reliable functionality, we test the devices with special test CDs. Using the so-called "eye pattern", which is measured with an oscilloscope, we can determine how well the laser reads the information on the CD. We use this data to decide, among other things, whether devices are still suitable for sale. whether the laser unit needs to be replaced. The devices are presentable . There may be a few small blemishes on the front and/or a few small paint scratches (no longer than approx. 5cm) must be present. From app.
