A pre-amplifier made at the State-of-the-art, realized with a great design features. It was projected in England by the historical ONIX engineers who have equipped this product with great stability of the circuit with innovative patents that make it a final product.

Front: Black Glass, gold knobs, power-on stand by that works by touching the gold bar, LED matrix to display the volume. Central LED to select different sound sources. Input selector made with SS technology (soft-select), the relay controlled by a microprocessor with a very low noise and with excellent separation of the inputs.

Rear: RCA CMC 805, balanced connectors with 24K gold rhodium-plated terminals, power supply with line filter, IR input and output. INPUTS: No°4 RCA line inputs, No°1 x RCA Phono that is sensitivity selectable for MM/MC, No°2 balanced XLR inputs, No°1 By-Pass RCA. OUTPUTS: No°2 RCA line inputs, No°1 XLR balanced input.

A65 Remote control
Aluminum remote control, suitable to be able to control all the ONIX flagship products. Made with high quality materials, resistant to time. Easy to understand, designed to be simple and intuitive.
