Crown macrotech with strange sensitivity settings

hey,

I have a driverack PA and I'm powering my mids with a Crown macrotech 3600vz.

The setting in the DRPA asks me to set the sensitivity for this amp and the options are

1.4 V
26 dB
.775 V

I opened up the back on the macrotech and the three sensitivity setting choices marked there on a sticker next to the 3 position settings switch are

32 dB
26 db
34.5dB

??????

The amp manual I have says they are supposed to be:

1.4 V
26 dB
.775 V

Can anybody shed some light on this anomaly? Do I have a non standard Macrotech?

I set the Mtech to 26 dB and set the DRPA to the same setting. Only thing is that on this setting the DRPA tells me to run the amp attenuators pegged at 100% which I don't feel comfortable doing.

Any suggestions?

Pete

    Sounds like a good question for the PSW forum. Give them a short. A lot more people there.
