31. For 2 m rx, the PIN diode bias is provided by the PA unit to 2 m preamplifier . 32. A typical application for the line trim is attenuating signals that were intentionally amplified too much by the microphone preamplifier . 33. Over amplifying the signal can cause the preamplifier to distort, which can under certain circumstances produce a desirable sound. 34. The typical 500 volts between the backside of the last MCP and the anode cannot be fed into the preamplifier . 35. A "'preamplifier "'( preamp ) is an electronic amplifier that converts a weak electrical interference. 36. If the bit depth of a recording is sufficiently great, that preamplifier noise will be sufficient to dither the recording. 37. PS Audio's first product was a standalone phono preamplifier , sold direct to consumers for $ 59.95. 38. Some players use separate preamplifier / power amplifier setups, where one or more preamplifiers drive one or more power amplifiers. 39. Some standalone bass preamplifier pedals have a DI output, so this output can similarly be connected to a PA system. 40. The signal flow begins as in the previous example; singer, microphone, microphone preamplifier , EQ, and compressor.
