31. In 1985, Wachner delivered a paper to the AES regarding guidelines for power amplifier evaluation. 32. Pairing high sensitivity headphones with power amplifiers can produce dangerously high volumes and damage headphones. 33. This multi-leaded power package is useful for such applications as audio power amplifiers , for example. 34. Some mixers intended for small venue live performance applications may include an integrated power amplifier . 35. In a polar modulation system, the power amplifier input signal may vary only in phase. 36. They are widely used in satellite receivers, in low power amplifiers and in the defense industry. 37. It can also be set at each power amplifier attached to a number of masking speakers. 38. From the late 1960s to the 1980s, most monitor speaker cabinets used an external power amplifier . 39. Thus both the power amplifiers are optimally used even for signals transmitted on the first antenna. 40. Many otherwise good power amplifier designs have been found to have inadequate slew rates, by modern standards.
