<p>PURPOSE:To secure the silent part in the broadcast program, by cutting off the signal to be supplied to the tape and at the same time stopping the tape running in the pause mode. CONSTITUTION:When swtiches S1 and S2 are at the record side, the record input is supplied to recording head 10 via S1, variable resistance VR2 and recording amplifier 8 each. At the same time, the recording state is monitored by monitor amplifier 6 and monitor output part 7 and via S2. Switches S1 and S2 can be switched in the interlocking state. If S1 and S2 are switched in case the normal radio broadcast is received, the output is delivered through S1, variable resistance VR1, S2, monitor amplifier 6 and part 7 each. As a result, the recording input is cut off from amplifier 8 and thus never recorded on the tape.</p> |
