I have these OSC and ALC switches on my Aiwa, but I still haven't figured out what they do
which aiwa because the alc is automatic level control has to do with recording on some boxes and on my aiwa 660 the osc is the beat cancel for the am radio and sw reception
'rarely right ramon' is right

But in this case.......he is.....
ALC: Automatically adjusts the recording level for the tape, many basic boomboxes and cassette recorders have this as a standard feature as it alleviates the need for user interaction when setting the optimum level. It also means a simpler, cheaper design with less components. ALC, depending on the manufacturer can give varying results and is not always suitable for all program material, giving rise to 'pumping' and over-zealous limiting characteristics.
OSC (oscillator) has been described under the pinned topic in this section 'What is Beat Cut'. Basically stops the AM heterodyne 'whistle' when two or more stations are being received on the same frequency. It also prevents the same effect when recording from an AM (MW) broadcast.
It's a TPR-950. So if you flick the ALC on, you don't have to adjust the input volume, but otherwise you would? Maybe that's why when I was making a test record, the volume never changed even though I was fiddling with the input volume.
This OSC thing, is it for listening, or recording?
i would belive for both if you were recording a program from am you do not want the interferance
from both station as described by 2steppa....

Interesting, and probably a handy feature to have if it works well. It's this 'whistle' which makes me avoid listening to the AM band for too long, because it can get annoying after a while. I'll have to see if any of my boxes have this OSC feature!
