LUXMAN L-509X Integrated Amplifier Class A audio music stereo NEW 100V

Innovative amplification feedback circuit, ODN F Ver.4.0

The original negative feedback circuit ODNF is a circuit that is the basis of Luxman's sound idea to obtain the speed of the initial slew rate and the ultra-wide band by feeding back only the distortion component from the output of the amplifier circuit.

The latest version of ODNF Ver4.0 adopted by L-509X improves distortion detection accuracy by 3 parallelization of the first stage of the error detection circuit, and by connecting the first stage of the amplifier circuit in parallel and the second stage in Darlington connection. Achieves low impedance and high S / N ratio.

The output stage boasts a 3-stage Darlington 4-parallel push-pull configuration equivalent to the power amplifier M-700u, achieving complete output linearity of 120W + 120W (8Ω) and 240W + 240W (4Ω). By fully driving speakers of all characteristics, we have achieved both the dynamism of music and rich musical expression at a high level.

* ODNF is an abbreviation for Only Distortion Negative Feedback.
