[Elecraft] K3 audio response, big roll off observed

Hi all, wonder if anyone can help me out. K3 audio frequency response in SSB or DATA mode has with flat EQ hughe rolloff. on the range 500-4000Hz there is 37dB roll off ! Bandwidth is set to 4KHz. Any ideas to what might be the cause? Measured with spectrum labs, screen dump is to be found here
