Microphone:
The microphone input
and designated Mic. Input, is designed for low-impe-
dance (balanced or unbalanced) microphones with 25
to 600 ohms impedance or high-impedance (unbalanced)
dynamic, ribbon, or condenser microphones. The unit is
not recommended for use with crystal or ceramic micro-
phones. The impedance is selected by a slide switch
(17) above the Mic. lnput receptacle. The input recep-

Figure 2 for low- and high-impedance connections to
Note: Some condenser microphones produce very high
output signals which may overload the input. Use
of an attenuator (such as the Shure
Microphone Attenuator) will improve this
