Gladen RC 105c4

The Gladen RC 105c4 is a powerful 4-channel amplifier from the RC series that impresses with high-quality Class A/B technology, a solid build, and versatile connectivity options. With an output power of 4 × 105 watts RMS at 4 ohms, it offers ample power reserves for demanding front and rear speaker systems. In bridge mode, it even delivers 2 × 300 watts RMS at 4 ohms.

Thanks to the built-in high-level inputs with an automatic power-on function (Auto Sense), the amplifier can be easily integrated into existing factory sound systems. The double-sided circuit board with modern SMD components ensures reliable operation and high-quality signal processing.

The RC 105c4 features adjustable high-pass and low-pass filters for flexible adaptation to different speaker systems. In addition, an optional remote level control can be connected for channels 3 and 4. Comprehensive protection circuits ensure safe operation even under high loads.
