Using a C2N-IIF as a doorbell - problem with audio
|
mrtgilberty
I'm using a C2N-IIF loaded with a WAV file to drive the local doorbell speaker of the C2N-IIF as well as feeding the speaker audio from the C2N-IIF back into the house into a BIPAD.
On my test bench this works fine, running into two amps to generate the audio, so the audio generates fine. However when installed at the customer site, the local doorbell (a Holovision door entry system) plays the audio fine, however the audio going through the BIPAD doesn't work and makes a very quiet muffled 'odd sounding' noise. The audio out from the C2N-IIF (via the Speaker outputs) - I have the SPK +/- wires going into the local speaker as well as feeding into a Direct Injection box to take the speaker level down to line level. This then feeds into one of the RCA stereo inputs of the BIPAD and into a AMPX. I've adjusted the impedence of the Direct Injection box from full to none however I can't seem to get anything to work. The levels of the AMPX are set to a sensible level and the rooms in question are 'activated' when the audio is playing after the doorbell button is pressed. The doorbell sound then plays on the local door-station speaker but not over the speakers in the house (ie via the BIPAD / AMP). Could there be a delay in the AMPX turning on each zone, or is there some sort of incompatibility of using a WAV file to play through the BIPAD and AMPX? (I'm beginning to clutch at straws as to what could be wrong!) Thanks Tom |

Yes. There is a delay. I just did this with AAE's instead of bipad but I

had to put 2 seconds of dead air at the beginning of my mp3. I played mine off of an mc3. Sent from my iBerryRex. RAWR On Dec 23, 2012, at 5:48 PM, mrtgilberty <mrtgilbert@...> wrote:

I would say start trouble shooting the audio playing first. Plug the output

Into something you know works to make sure it plays your wav then once that is good then troubleshoot timing issues. Nick Sent from my iBerryRex. RAWR On Dec 23, 2012, at 5:48 PM, mrtgilberty <mrtgilbert@...> wrote:

Which DI box do you have?
Are you using a balanced output? How are you wiring that to an RCA? Typically you'd tie - and ground (pins 1 & 3 in an XLR) together for the RCA ground. Chris On Dec 23, 2012 4:48 PM, "mrtgilberty" <mrtgilbert@...> wrote: ** [Non-text portions of this message have been removed] |
