BLACK IN 7 OUT OF 10 COSMETIC. WORKS PERFECT>
Phonomena offers unprecedented cartridge-loading flexibility! There are 16 steps of gain, ranging from 40 to 60 dB, and 128 load impedance settings available, ranging from 30 to 100 k-ohms. Two capacitance choices are available for loading moving magnet cartridges. Removing the metal top plate of the 12" by 5" by 2" chassis , allows access to the small DIP switches, which allow the user to set the gain and impedance for virtually any cartridge. A group of 8 DIPs (4 for each channel) control gain and another group of 16 (8 for each channel) set capacitance and impedance, resulting in a choice of 2,112 possible combinations.
The circuit is a class A design, incorporating discrete, matched, low-noise input transistors and a dual mono layout. Very highly reviewed when it was first available in 2001.
American made using discrete transistor topology and has a "Constant ON" feature for thermal stability.
