More Information


The Pre Box S2 Analogue is a compact pre-amplifier for integrating into hi-fi systems where space is at a premium.

With three stereo Line Level (2x RCA pair, 1x 3.5mm jack) inputs, the diminuitive Pre Box S2 Analogue can accomodate three full-size source devices with ease. The stereo Pre Output allows for connection to a power amplifier (ideally the matching Amp Box S), while the additional 3.5mm Fixed Output allows for onward connection to a subwoofer, or even an analogue headphone amplifier for private listening sessions. 

Internally the advanced circuitry of the Pre Box S2 Digital ensures the electrical signal is handled with care and accuracy, achieving incredibly low harmonic distortion levels for a clean, pure, analogue audio performance. 

The Pre Box S2 Analogue has a 12V trigger output, so it can turn on connected devices - such as the Amp Box S2 or Switch Box S - for improved comfort and convenience. Power is provided by the included power supply, but you can upgrade your convenience further by switching to any 5V power bank. Housed within the improved S2 chassis, the overall build, convenience and performance of the Pre Box S2 Analogue is enviable for the price.
