Probably no mike gain control because the audio input is designed for
approximately 45 millivolts level and the included electret microphone
puts out approximately 45 millivolts. 
Secondary reason is that it avoids possibility of cranking the gain up
too high, overdriving the balanced modulator and causing unwanted
emission products.
