Class A Amplifier Bluetooth 5.0 2x70W 8Ω
Based on a proven and efficient architecture, the Original Audio OPA-10 Class A amplifier ensures a musical and dynamic sound reproduction. Its powerful amplifier circuit allows it to develop a power of 2x70W under 8Ω. Each channel of the amplifier embeds for that a 2SA1695 transistor and a 2SC4468 transistor. The input stage of the device integrates an OPA 5532 to provide a wide dynamic range and low distortion. The power supply stage of the OPA-10 is designed to provide a clean and perfectly stable electrical signal to the amplification circuit. At the base of this power supply, there is a toroidal transformer made of pure copper, perfectly isolated, as well as large filtering capacitors.
The connectivity of the OPA-10 is simple and efficient with stereo RCA and USB input. However, this connectivity is completed by a Bluetooth 5.0 receiver allowing you to broadcast your music remotely, for example from a smartphone or a tablet.
