volume-limiting amplifier [`väl·yǝm ¦lim·ǝd·iŋ `am·plǝ´fī·ǝr] ELECTRONICS Amplifier containing an automatic device that functions only when the input signal exceeds a predetermined level, and then reduces the gain so the output volume stays substantially constant despite further increases in input volume; the normal gain of the amplifier is restored when the input volume returns below the predetermined limiting level. |
