(Converters) Monitor Audio Ch 15 & 16 on a SDI signal

I have a feed from an HD SDI, I'm converting to HDMI and like to know if there any way I can select to monitor only Channels 15 & 16.

Thanks

Depending which converter you have this may be possible.
Converters manual, eg. page 18.

But most converters will only do channel 1 and 2.

I bought broadcast monitors for this purpose to be able to monitor all 16 channels.

That's why you need better converter, eg. AJA does either 1st 8 or 2nd 8 channels out of 16 SDI ones on HDMI (+ any chosen 2 on analog output).

Juan wants exactly 2- just not first 2, but 15+16. This is possible with some BM converters.
