Description

[Detailed Description of the Invention] The present invention relates to an audio device, and more specifically to a system for selectively transmitting multiple sources such as a tuner and a record player to a tape recorder according to the recording settings for each source of the tape recorder. The present invention relates to a device that supplies a source signal specified on the tape recorder side to a recording circuit of a tape recorder by switching a selector of a preamplifier that has a tape recorder.

Current audio systems have many sources, such as record players, tape recorders, and tuners, and a preamplifier that inputs signals from these sources and selectively amplifies them, and supplies them to the recording circuit of the connected tape recorder. , and a device that amplifies the power of the output of the preamplifier and reproduces it. In such a system, when recording signals from other sources using a tape recorder connected to the preamplifier, you must operate the preamplifier's source selector to select the source to be recorded in addition to the tape recorder's recording operation. The selection has to be made, which makes the operation complicated, and there is a risk of forgetting to operate the preamplifier or erroneously specifying the selector and not being able to make the desired recording.

The present invention solves the above-mentioned drawbacks, and includes a tape recorder, a source selection device that selects one of the sources connected to the input terminal, and a signal of the selected source that is transmitted to the recording circuit of the tape recorder. A recording source selector provided in the tape recorder; a signal generator that outputs a source selection signal based on an operation of the recording source selector; and means for outputting a recording instruction signal based on the operation,
The present invention provides an audio device configured to operate a source selection device of an amplifier via the source selection signal by operating the source selector, and to put a tape recorder into a recording state via the recording instruction signal.

are selected and the playback signals from tape recorder 1 from IN ₄ are transmitted. Note that 3 is an equalizer amplifier, which amplifies the signal from the record player to a predetermined level and performs frequency compensation according to the RIAA standard. The source signal from the source selection device 4 is supplied to a reproduction system, and is also supplied to a transmission line P and transmitted to a recording circuit (not shown) of the tape recorder 1.

Next, in the tape recorder control section T, S ₅ to _{S 7}
is a recording and source selector switch, and by operating this switch, the recording memory circuit FF is set and a recording instruction signal is output from its output terminal Q to put the tape recorder 1 into the recording state, and this recording instruction signal is used. Turn off the control signal supply switch 5 of the preamplifier 2 and turn off the source selection switch S ₁ to _{S 4}
Even if , the switching control signal is not applied to the selection device 4, and the selection device is maintained in its current state while the tape recorder 1 is recording. At the same time, the signal generator 6 is operated via the selector switches S ₅ -S ₇ to output a source selection signal from its output terminals O ₁ -O ₃ and applied to the source selection device 4 of the preamplifier 2.

In this case, the source selection signal output from the output terminal O ₁ by operating the selector switch S ₅ switches the source selection device 4 to the signal terminal C ₁ (record player), and the source selection signal output from the output terminal O ₂ by operating the selector switch S ₆ .
The source selection signal output from the output terminal O 3 switches the source selection device 4 to the signal terminal C ₂ (tuner), and the source selection signal output from the output terminal O ₃ by operating the selector switch S ₇ switches the source selection device 4 to the signal terminal C 2 (tuner).
Switch to C ₃ (AUX).

When the recording state of the tape recorder 1 is canceled (by stopping or switching to another operation), the recording memory circuit FF is activated by a signal indicating the cancellation (STOP, FF, REW in Figure 1).
is reset, the recording state is canceled, and furthermore, the operation of the signal generator 6 is stopped by the output signal of the memory circuit FF. Also, when the recording instruction signal disappears, preamplifier 2
