You can still use the Snom PA1 I would think. Just reduce the PA1's output levels to line level for input into the Valcoms and use a regular 24VDC power supply to send power. The wires can be terminated directly into each:

> We're trying to find the best way to interface 3 old Valcom speakers V-1030c to an IP paging system.
> I have a Snom PA1 but that won't work as we initially thought because speakers need 4 wires on a 24v power system. So 2 wires are for 24v power, and the other 2 are for audio. The snom only has a positive and negative output that feeds passive speakers, not active speakers like these.
> What is the best way to utilize these 3 speakers or should we just replace the speakers? We're trying to keep budget to a minimum for them so we would prefer to utilize the same speakers but what's the best way to power them and feed them audio using the existing 2-pair RJ11 cable they use?
> Thank you
