Gladen RC 70c4

The Gladen RC 70c4 is a powerful 4-channel amplifier from the RC series that combines high-quality sound with a compact design and versatile connectivity options. Thanks to proven Class A/B technology, the power amplifier delivers precise, dynamic, and detailed music reproduction.

With an output power of 4 × 68 watts RMS at 4 ohms or 4 × 105 watts RMS at 2 ohms, this amplifier is ideal for driving high-quality front and rear speakers. In bridge mode, up to 2 × 210 watts RMS at 4 ohms is available, allowing even more powerful speaker systems or subwoofers to be driven.

The integrated high-level input with auto-sense function allows for integration into existing factory-installed radios without a separate remote connection. Variable high-pass and low-pass filters ensure flexible adaptation to different speaker configurations. A double-sided printed circuit board with SMD components, a solid aluminum heat sink, and comprehensive protection circuits ensure reliable operation.
