Record - Reproduce Audio Problems



Note: Direct audio is live time audio before it is put on the tape. 

Of course, direct audio should be checked first to ensure that you have 

a good input signal.



There is no way to check the record audio between the time it is 

first put on the tape and when it is reproduced. Reproduced audio is 

audio that has been picked off of the tape by the reproduce head and 

sent to the reproduce amplifier. It then leaves on pin 7 and is sent 

to SW204. SW204 selects the transport that is the source of the 

reproduced audio. From SW204 the audio goes to the monitor amplifier 

to drive the VU meter and speaker.



If direct or reproduced audio is bad on only one channel, on one or both 

transports, a record amplifier should be suspected.



If audio on all channels is bad only on one transport, the more likely 

problem would be a reproduce amplifier.
