Pre Box S2 Analog features three line level inputs (2x RCA pairs, 1x 1/8″ stereo mini), meaning up to three analog sources can be sent off to the power amp via the RCA output. There is also a fixed line-out (1/8″) that can be relayed to a separate component such as Head Box S2 (our dedicated headphone amp from the S2 Series). The 12V trigger output can remotely engage products with a trigger input such as our Amp Box S2 stereo power amp. Incredibly low harmonic distortion levels guarantee a listening experience previously unattainable at this price. The housing is made from an aluminium/steel sandwich construction for sleek aesthetics and as well as EMI & vibration resistance.
