Congratulations on your purchase. Please take a few moments to read this manual, and retain it for reference. The Pre One/A is the control center for your audiovideo system. It features versatile switching and dubbing capabilities, with six inputs for line level components. Two sets of master line outputs allow for either a direct subwoofer connection or multiple amplifiers. Two AC power inputs permit direct connection of system components. The Pre One/A carries a full, two year, transferrable warranty. Front Panel Controls Power This front panel button switches the unit on or off. A multicolore d LED indicates its power status. Input Selector Buttons (Tape, Tu n e r, Aux, CD, DVD, LD) Press any of these buttons to select the input source. The red LED indicates your selection. These buttons correspond to the wiring on the back panel, so the CD button, for example, selects the unit plugged into the CD input. The tape button activates a tape loop, allowing you to use a signal processor (graphic equalizer, sur round sound processor, etc.). The tape button can be on while another button is also selected, allowing you to equalize or process CD’s, videotapes, radio broadcasts, or other signals. Bass & Treble Controls Tu rn these controls clockwise to increase the amount of bass (low frequencies) or treble (high frequencies). The 12:00 position indicates a flat response, equal levels of bass, treble and midrange. Balance Control Tu rn this knob counterclockwise to increase the volume of the left channel, clockwise to increase the volume of the right channel. The 12:00 position indicates equal output to each channel. Volume Control Turn this control clockwise to increase the overall system volume. Be careful not to set the volume so high as to cause distortion, as this could damage the speakers and amplifier.
