DCR 822 and SrC audio out level question


Recommended Posts

I have both the DCR 822 and SrC receivers. Both have a Lectro SMV as a transmitter sending to one of their respective channels. From my research and reading, I understand that lectrosonics recommends maxing out the audio out level on the receiver side, but the 822 max is +7dB and the SrC is +5dB.

 

My question is if I want to match both SMVs sound and levels, should I match the DCR822 to +5dB like it is with the SrC or I compensate the difference downstream through my recorder's (SD633) gain stage? Or does it not matter at all?

 

Both SMVs are set at the same settings.

 

Any input appreciated. Thanks!

We were able to get a little more out (+7dBm) of the DCR822. And our general statement of running receivers wide open when you can is the theoretical best operating point. But here's a case when you have a solid reason not to run the DCR822 wide open; to match the SRc receiver. The +5 dBm level is so close to wide open, I'd run it at +5dBm and cut down on downstream confusion. Any level above -20dBm gives you full SNR. Levels above -20 dBm help suppress ground loops and electrical noise induced in the cables.

Thanks! This makes a lot of sense.
