Audiophile dockingstation. Dock Box S Fi makes your iPod part of your audiophile hifi system at home. Dock Box acts like a perfect buffer amp for the iPod and therefore lowers the distortion level significantly.After passing an initial amplifier section, the signal is transferred to the hi-fi system with an impedance lower than 15 ohms. This guarantees troublefree signal transmission with ultra-flat frequency response and offers the best, most cost-effective way to build an audio system around an iPod. • Compatble with all current models: iPod, iPhone, iPad• Fi version with constant volume level - ideal when combined with existing hifi audio system• Perfect signal transfer from 30-pin analogue-out• Full metal housing prevents interference• RCA stereo output• S-video output for on-screen monitoring• USB port for data transfer from PC/Mac• On/Off switch on front• Remote control included Frequency response: 20Hz - 20kHzHigh level audio output : 1 pair RCA connectorsOutput impedance : 15 ohmsOutput voltage : 0,300VeffUSB port : digital serial protocol, USB 1.1 (Windows® and MacOS®)Video output : S-videoPower supply : 18V/500mDC, 220 - 240V, 50HzPower consumption : 16V/200mA DC max, depends on battery status.Remote battery : 1 x CR2025 3V
