Design:
4 sets of stereo pre outputs via balanced XLR connectors and a single set via unbalanced RCA/phono connectors, 6 unbalanced line-level inputs, 4 balanced inputs, tape monitor and record out. Input number "6" was ommited as the input switches on the front panel represent their relative positions on a clock face - there is no input switch where 6 o'clock would be, so no "input 6". Remote control with logic-controlled input switching and motorised volume pot. Touch-sensitive buttons on the fascia. Two sets of voltage trigger outputs enable the activation of The Pre to simultaneously power up matching Alchemist The Mono or The Stereo power amps. Original selling price: 5,000
