专利汇可以提供Electrical audio signal processing专利检索，专利查询，专利分析的服务。并且An electronic loudspeaker equalizer network is coupled to the tape monitor jacks of a receiver, preamplifier-amplifier or preamplifier. When the receiver, preamplifier-amplifier or preamplifier has the tape monitor switch positioned in the IN position to select the tape monitoring function, the electronic equalizer network electronically equalizes the overall frequency response so that the radiated power spectrum of the loudspeaker connected to an associated amplifier is substantially flat over the audio frequency range. The electronic equalizer also includes a tape monitor switch and tape monitor jacks so that a tape recorder may be connected to the electronic equalizer and the recorded signal monitored with the equalizer tape monitor switch in the IN or MONITOR position, the latter signal first passing through the electronic equalizing network.，下面是Electrical audio signal processing专利的具体信息内容。

权利要求

1. Apparatus for association with but separately packaged from audio signal amplifying means having a tape monitor switch for selecting a tape monitor function, a ''''to tape recorder'''' terminal means and a ''''from tape recorder'''' terminal means, said apparatus comprising, active audio electrical signal processing circuit means having an input and an output for providing equalization of an input signal over at least a portion of the audio frequency range, input terminal means for coupling to the ''''to tape recorder'''' terminal means, output terminal means for coupling to the ''''from tape recorder'''' terminal means and coupled to said circuit means output, additioNal ''''to tape recorder'''' terminal means for coupling to the input of a tape recorder and coupled to said input terminal means, additional ''''from tape recorder'''' terminal means for coupling to the output of a tape recorder, and additional tape monitor switching means for selectively coupling said circuit means input to said input terminal means when the additional tape monitor function is out and to said additional ''''from tape recorder'''' terminal means when the additional tape monitor function is in, whereby when the additional tape monitor function is out said additional tape monitor switching means comprises means coupling both said input terminal means and said additional ''''to tape recorder'''' terminal means to said audio electrical signal processing circuit means input while then keeping said additional ''''from tape recorder'''' terminal means disconnected therefrom and when the additional tape monitor function is in said additional tape monitor switching means comprises means coupling said additional ''''from tape recorder'''' terminal means to said audio electrical signal processing circuit means input while keeping both said additional ''''to tape recorder'''' terminal means and said input terminal means disconnected therefrom.

2. Apparatus in accordance with claim 1 and further comprising, said audio signal amplifying means and means for coupling said ''''to tape recorder'''' terminal means to said input terminal means and means for coupling said output terminal means to said ''''from tape recorder'''' terminal means, and tape recorder means having an input coupled to said additional ''''to tape recorder'''' terminal means and an output coupled to said additional ''''from tape recorder'''' terminal means.

3. Apparatus in accordance with claim 2 and further comprising a loudspeaker system coupled to said audio signal amplifying means, said audio electrical signal processing circuit means comprising active equalizing means for coacting with said loudspeaker system to establish a radiated power spectrum of said loudspeaker system that is substantially flat over the audible frequency range.

4. Apparatus for association with but separately packaged from audio signal amplifying means having a tape monitor switch for selecting a tape monitor function in accordance with claim 1 wherein each of said ''''to tape recorder'''' terminal means, said ''''from tape recorder'''' terminal means, said input terminal means and said output terminal means comprises standard phono connectors.

5. Apparatus for association with but separately packaged from audio signal amplifying means having a tape monitor switch for selecting a tape monitor function in accordance with claim 4 wherein each of said standard phono connectors is a jack for receiving a standard phono plug.
