Similar Threads complex voice recorder 1. Also a noise like sound is coming through out from the speaker, Why this happens ans how to rectify that thing?
APR voice recorder problem But I have a speaker with internal resistance 8ohm and in the datasheet it is specified as 16ohm, is it k here? Equating complex number interms of the other 6. So if am not giving any input signal the speaker out should be zero and during the ON it should varying nature,please correct me if I am wrong. This pin forces a jump to message 1 for either recording or playback. Then set the initial conditions for CE and RE as low for record. Help me with a voice recording equipment project!
Waiting for a good reply: Datashewt recording a low level on this pin indi- cates that the end of the memory array was reached. Auto Rewind Option Message: Thanks so much for the advice. APR voice recorder problem http: APR voice recorder problem Hi guys, I have tried the circuit diagram given in the datasheet see my first post in random access mode using 8 switches.
Results 1 to 20 of When I am connecting the IC to supply the busy LED turns ON and from the datasheet what that signifies is the device is currently busy performing internal ap9r600 and can neither record nor playback at the current time. What is the function of TR1 in this circuit 3. PNP transistor not working 2. The strobe LED is also blinking continuously when connected to the supply.
And any idea why these kinds voltage levels coming in M8 and M9 pins as I mentioned that thing my previous post: A low edge on this pin plays or records the next message. Thanks in advance, Akhil.

Dec 242: A low edge on this pin plays or records the current mes- sage. APR voice recorder problem I have done that already, but not hearing any beep sound when there is a high to low transition on pin1. Why this happens aapr9600 my case?
Is am making my point in a confusing manner, any way I am sorry If I am doing that: This pin forces a jump to message 3 for either recording or playback. Dec 248:
