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.
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.
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.
