Balanced / Single-Ended Preamplifier NFCA

Topping Pre90 Préamplificateur Symétrique / Asymétrique NFCA

Topping's Pre90 is a high-performance preamplifier based on a fully balanced circuit and high-performance NFCA modules. It also benefits from a high quality volume attenuator and easy control, thanks to its front panel display.

Test By Audio Science Review

It is an instrument grade, more transparent than transparent, preamplifier. Other than Benchmark HPA4, I don't think it has an equal no matter how much money you spend. In that regard, it is quite a value as well although obviously not "cheap" as compared to desktop products.

High performance NFCA modules

At the heart of the Pre90 are NFCA (Nested Feedback Composite Amplifier) modules, similar to those integrated in the excellent Topping A90. This hybrid voltage/current architecture combined with UFGF (Ultra High Gain Feedback) technology offers excellent DC and AC performance. The Pre90 has an ultra low noise level of 0.3µV and an incredible dynamic range of 145dB, to provide accurate, immersive and rich sound reproduction.

Balanced circuits

The Pre90 adopts a fully symmetrical structure, allowing both symmetrical and asymmetrical signals to be processed. The output can thus be balanced, unbalanced, or a combination of the two options. In addition, with its balanced and unbalanced inputs, the Pre90 can be used to convert balanced to unbalanced or, conversely, unbalanced to balanced.

Amplification of weak signals

With a maximum gain of +16dB, the Topping Pre90 can easily amplify weak input signals to an acceptable level to deliver to your amplifier. In addition, its 0.3µVrms noise level is extremely low, so the Pre90 does not add any audible noise during signal amplification.

Volume attenuator

Using a number of high-quality Japanese relays for its volume control, the Pre90 allows precise adjustment of the sound level, while maintaining perfect channel balance. In addition, if the volume level was high when the unit was turned off, the Pre90 will automatically reduce the sound level the next time it is turned on to preserve your audio system and hearing. It is also possible to use and adjust the "Safe Volume" function, which allows you to indicate a maximum volume level (this function can be deactivated).

Topping Ext90, a perfect extension for maximum versatility
Optional product, sold separately

The Pre90 offers a balanced XLR input and an unbalanced RCA input. The Ext90 is the perfect companion to the Pre90, providing two unbalanced RCA inputs and a total of four balanced XLR inputs. Ideal for a multi-source system.

Selectable outputs

The Topping Pre90 allows you to select the active output. It can be set to "XLR only", "RCA only" or "XLR+RCA". Thus, the amplified signal can be sent to two different amplifiers.

Volume memory

The Pre90 has an independent volume memory for each input or output. When several inputs with different levels are connected, changing the active input often requires readjusting the volume level . The volume memory thus allows automatic adjustment to the last saved parameter for each input. It is possible to choose to use this memory for the outputs, in order to adapt the level according to the destination amplifiers.

The Pre90 can only store either the input volume or the output volume, but not both at the same time.
