Purpose-built PA endpoint

The Snom SNO-PA1 is a SIP-enabled public announcement device that connects to an existing IP PBX and adds a 4-watt Class D amplifier for paging and background music. It targets facilities managers and integrators who need a network-attached audio zone for offices, retail spaces, transport hubs or educational sites.

Fit and constraints

This unit suits installations that already have passive loudspeakers and a PoE infrastructure, because it draws power through IEEE 802.3af class 3 and provides speaker terminals rather than a built-in driver. Buyers who need an all-in-one speaker with integrated drivers, or who require Wi-Fi connectivity, should look at a different product class.

Decisive specification

The 4-watt Class D amplifier determines whether the SNO-PA1 can drive the intended coverage area with the connected passive speakers; if the zone demands higher output power, this device will not meet the requirement.

Questions about this item

Do I need an external loudspeaker for the 4 W class D amplifier to broadcast announcements?

Yes, the unit includes a 4 W class D amplifier but the loudspeaker is not included, so you must connect your own speaker to one of the two 3.5 mm jacks.

Can I daisy-chain additional PA1 units using the built-in 10/100 Mbps switch ports?

Yes, the two Ethernet ports operate as a switch, so multiple PA1 units can be linked together and to the network without a separate switch.

Which LED indicators confirm the PA1 has registered with the SIP server and is ready for announcements?

The device provides two LED status indicators; their exact meanings are described in the web interface and the quick-start guide.
