Power amplifier Braun Atelier HiFi PA4:
Quote from the Braun brochure at the time:
"The PA4 is the ideal complement to the Control Center CC 4 and can also be remotely controlled via it. Strictly speaking, the PA4 is a power amplifier. That says what sets it apart: its extraordinary output power, namely. When the preamplifier and power amplifier are separated, you can give a system greater power. This is how the CC4 and the PA4 were born. The PA4 has 2 x 250 watts of music power and effortlessly drives two pairs of speakers, which you can switch on or off using our RC1 remote control. To avoid distortion at high volume, Braun engineers used high quality, high speed transistors and low loss capacitors per channel. Several electronic protection circuits protect our power amplifiers from all conceivable influences: Overloading of the power stages as well as overheating, accidental wrong connection and so on. The PA4 is a powerful power amplifier that behaves neutrally even at high volumes and impresses with its high musicality. You can also use it as a mono power amplifier and expand your system to 2 x 450 watts of music power with two PA4s."
