Page 4: Power Output
Description: BK Butler’s MONAD A100 is a 300B Class A vacuum tube-driven monoblock power amplifier. Both RCA and true BALANCED precious metal plated input jacks of the highest quality are provided. The RCA input jack and the 5-way speaker output binding posts are top of the line Cardas. -

condition in the case of a direct short circuit between the + and - output speaker binding posts. 7. Over Temp Circuit Breaker: Opens the speaker relay if the heatsink temperature exceeds 115 deg. C. If this occurs, the amp will automatically begin operate again after the temperature has decreased sufficiently. -
Page 6: Inputs
Inputs: The highest-quality Rhodium plated Cardass RCA-type input jack will accept the line-level signal supplied from most pre-amplifiers. The silver plated Neutrik XLR accepts true balanced signals. The input gain has been internally preset to equal full (100 Watts) output at 8 ohms for an input sensitivity of 1.7 Volts. -
Page 7: Cable Quality
Cable Quality: It has been our experience that you generally get what you pay for in cables. A good set of shielded input connection cables coupled with large gauge, high quality low-loss speaker wire is well worth the investment. Do not degrade the remarkable performance of this amplifier with inferior connecting cables. -
