Power amplifier Braun Atelier HiFi PA4/2:
Quote from the Braun brochure from back then:
"The PA4 is the ideal complement to the Control Center CC 4 and can also be remote controlled via it.
Strictly speaking, the PA4 is a power amplifier. That says what distinguishes it: its extraordinary output power. When the preamplifier and power amplifier are separated, you can give a system more power. This is how the CC4 and the PA4 came into being. The PA4 has 2 x 250 watts of music power and easily 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 with two PA4s to 2 x 450 watts of music power."
