Details

"Discrete" versión of Topping LA90D

Topping LA90 Discrete, an unprecedented performance benchmark will bring you a breathaking listening experience. The newly developed discrete NFCA power amplifier reaches a new level of pristine sound and accuracy. The unprecedented level of performance will bring you the absolute amaze the sound quality. You will experience the darkest background you ever experienced with jaw dropping clarity.

High power and minimal distortion

The THD+N of the LA90D is extremely low. As detected, it is less than 0.0001% under 4/8Ω at 5W. These specifications allow a precise reproduction of the source signal, to guarantee a very high level of quality and power.

Balanced inputs and two gain levels

This Topping LA90D incorporates three balanced outputs. For their part, the inputs have a combined format, which allows the use of cables both XLR and 6.35mm TRS jack. In addition, the other connectors allow the unit to be used in mono mode.

In order to adapt to any audio system, the LA90 Discrete offers two levels of adjustable gain:

-Low Gain: Levels +9.4dB in stereo or +15.4dB in mono.

-High Gain: Gain of +19.4dB in stereo or +25.4dB in mono.

Configurable in mono and stereo

The Topping LA90 Discrete can be configured and wired to operate in stereo or mono mode, and combining a pair of amplifiers provides increased power. When used in mono mode, the minimum impedance is 4Ω.

Robust and redesigned chassis

El LA90 está revestido en un chasis de aluminio mecanizado CNC de precisión.

Estos materiales otorgan al amplificador un diseño moderno mientras protegen efectivamente los componentes de la unidad. Los lados del LA90 Discrete tienen grandes disipadores de calor, lo que permite que el calor emitido por la electrónica interna se disipe de manera efectiva.
