されている。Conventional configurations and their problems Conventional audio equipment with a built-in oscillation device for adjustment is very effective for matching performance and characteristics with external equipment, and is often included in high-end products. .
ところで、近年留守録音が発達し、タイマース
イツチによる録音が多く行われるようになつてき
た。たとえばチユーナに調整用発振装置を内蔵し
て留守録音をする場合を考えてみる。 By the way, in recent years, recording when someone is away has developed, and recording using a timer switch has become more common. For example, consider a case where a tuner has a built-in adjustment oscillation device and is used to record while the user is away.

時刻にチユーナ、テープレコーダに電源が印加さ
れ、留守録音が行なわれる。 Now, set the tuner changeover switch so that the output of the adjustment oscillation device is output, and receive the output signal of the adjustment oscillation device with the tape recorder to adjust the recording level of the tape recorder. Next, set the tuner's changeover switch so that the tuner's own output comes out, set the tape recorder so that you can record while you are away, and set the timer. Power is applied to the tuner and tape recorder at a time preset by the timer, and recording is performed while the user is away.

出力が録音されていない結果になるという欠点が
あつた。 If you use the tuner's adjustment oscillation device to adjust the tape recorder's recording level when setting up this absentee recording, you must always switch the tuner's changeover switch from the adjustment oscillation device's output to the tuner's output. . However, since the power to the tuner and tape recorder is turned off when you set up recording while you are away, you may not notice even if the switch on the tuner is set to the adjustment oscillator. The disadvantage was that the signal of the oscillator was recorded, but the output of the tuner was not recorded.
