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 S2) while the additional 3.5mm Fixed Output allows for onward connection to a subwoofer or even an analogue headphone amplifier for private listening sessions.
