[Detailed description of the invention] 'The main idea a tape recorder i-kinning device-to
compensate for the magnetic tape vak soundability enriched in the first stage amplification 1illfi
path (prea' knob) of the tape V Goda The equalizer circuit is used as the first stage amplification /
one path of the microphone circuit. The signal from the magnetic tape and the signal from the
microphone t-combine to obtain an output. The output of the equalizer 1 circuit that
compensates for the brass acoustics of the magnetic tape and the output of microbo / 4 @ 儲tA is
in agreement. However, it is very uneconomical and expensive to have a microphone increaser #
# exclusively used for installation -2. The present invention utilizes the inopydance viscosity of
de to the reproduction lying close to the input side of the preamplifier at the time of
reproduction, and emphasizes the high region of the station 1 inverse number of the microphone
output at the input side of the preamplifier, by the reproduction equalizer The signal from the
microphone and the signal from the microphone microphone 1 etc. are practically reproduced
without deterioration of the sound quality of the audio signal from the microphone by
compensating for the reduction of the high frequency band. It is provided by Mikin / gu J5 @ 're

the inductance component is the main component of the reproduction-rad 1's impedance, as
shown in FIG. 4, in the audio frequency range, it is expressed by approximately ωL. Fig. 3 and

It is covered as a voltage with a deviation. This voltage becomes RR of several percents of riC in

recorder, goes to the 4th, and the microphone and the microphone input / output of the
preamplifier for compensating the recording acoustics of the magnetic tape! At the same time, it
is possible to mix songs, so it does not require a microphone # and thus is economical and its
practicality is great. 4. Between the drawings 1 1 1 Description of Fig. 4 μ block diagram of one
