The Topping Pre90 has a safe volume option that activates when the set safe volume exceeds the target input\/output jack. It saves your expensive equipment from damage due to sudden high volumes. This feature can also be turned off from the settings menu using the remote control.<\/p>\n
The Topping Pre90 delivers outstanding performance. It also features a hybrid voltage-current feedback architecture and ultra-high gain feedback that enables noise-free, distortion-free signal amplification for weak audio signals.<\/p>\n
With the help of the Topping Ext90, you can connect multiple sources to the Pre90 at once. By itself, the Pre90 has one single-ended RCA and one balanced XLR input, but with the Ext90, it can be connected to up to two RCA inputs and four XLR inputs. The active input source can be easily selected using the included remote control. What's more, the Pre90 remembers your volume settings for the different input\/output jacks.<\/p>\n

The Topping Pre90 is a high performance preamplifier designed with a fully balanced circuit and advanced NFCA (Nested Feedback Composite Amplifier) modules. This hybrid voltage\/current architecture, combined with Ultra High Gain Feedback (UFGF) technology, ensures exceptional DC and AC performance, characterized by an ultra-low noise level of 0.3\u03bcV and an outstanding dynamic range of 145dB. The Pre90 supports both balanced and unbalanced inputs and outputs, making it versatile for a variety of audio setups, including the ability to convert signals between balanced and unbalanced formats. With a maximum gain of +16dB, it effectively boosts weak input signals without adding audible noise. High-quality Japanese relays enable precise volume control while maintaining channel balance, and the device has a "Safe Volume" function to protect your audio system and hearing. The Topping Pre90 also offers independent volume memory for each input and output, automatically adjusting to the last saved settings, and can be paired with the Ext90 for additional input options, making it an ideal choice for a multi-source system.<\/p>\n
