![]() wav files and record them over and over on the CD. The free version allows you to make 3 second recordings, but you can record 99 tracks on a CD, and so you can make your. I linked to a tone generator in this thread. Aim your antenna in the direction of the broadcast towers shown on map. Enter your address or use current location. This keeps you from shorting the inputs and frying the deck, and will be close enough for gov'mnt work. The RCA Signal Finder app allows you to find the best direction to aim your antenna for the broadcast towers in your area. The amp gain has to be set to the minimum setting, but all else I said above applies. And the tones should be recorded at the reference of 0 db.Ī safer solution to finding this input is to read the AC volts at the speaker terminals of the amp. For the surest reading you will set the deck volume to it's maximum unclipped signal, use several tones in the range of the speakers that the input is feeding, and get your combined result from that series of tests. The voltage will fluctuate depending on the frequency and the ampitude of the tone. You must use a test tone sine wave for a steady reading. But you must be very careful when you do this.DO NOT short the pos with the neg, and that's easy to do with those meter probes. ![]() You can read AC volts on the RCA terminal after disconnecting it from the amp. Why in the first place do you feel that you need to test the voltage on the inputs? Is there a problem with the system? Let the forum know.but to answer your questions:Ī music signal is AC. I can only guess that the signal off of regular music is too random and too fast of a signal for the mutlimeter to pick up.Īnybody else want to experiment with me, and come to a conclussion of their own and post it on here as to their findings? I am thinking of burning a 200hz constant test tone signal onto a CD and playing that, and seeing if I will get any results using the DC portion of the multimeter. I dont get it? Anybody wanna explain my findings here? 40 volts, compared to the 1.40 volts I got earlier. I then put the negative lead of the multimeter on the positive portion of the RCA plug and that gave me a reading as well, but it wasnt as high, it was around. IE when I put the positive multimeter lead into the positive part of the RCA plug, it gave me a reading of 1.40 without having to touch the other negative plug with the shell portion of the RCA. Most amplifier installation kits include 1 set of RCA cables that send the signal from your radio via a pre-amp output to the input side of your amplifier. ![]() When I switched it over to AC, I got some mixed readings.
