Combined stereo and surround integrated amplifier. Can automatically be switched between 2 and 5 channels by selecting the input. Lots of power: 2x 250W or 5x 100W in 8 ohms, 2x 400W or 5x 160W in 4 ohms. 4 line input, 1 tape output and 1 balanced XLR input in stereo mode; 5.1 line input in surround mode. 18 pcs 25A power transistors and 2x 500W transformer. Wonderful detailed and well-balanced sound with lot of dynamics. Due to very big and solid transfo, weight is over 22kg. Nice red display. Remote serves to select input and volume (other controls for other Thule devices). Big rotating gold-colour volume control on the front. Input selector at the right of the display. Left of the display control for volume for each separate channel. Subwoofer and center channel can be activated as the mono signal in stereo mode. Because of the weight pick-up or personal delivery (Belgium, NL or France North of Loire) is preferred.
