VoIP paging adapter for analog amplifiers

The Algo 8301 connects legacy paging systems to a SIP network. It is built for facilities that want to keep existing amplifiers while adding IP-based announcements, bells or emergency tones.

Wideband audio with balanced output

G.722 wideband support and an isolated, balanced line output deliver clear speech without hum or ground-loop noise. The adapter offers XLR and terminal-block connections compatible with -10 dBm, 0 dBm or +4 dBu amplifier inputs.

PoE powered with dry contact closure

Power over Ethernet supplies the unit so no local mains outlet is needed. A dry contact relay is available for amplifiers that require a closure trigger. Automatic level control and selectable frequency masks maintain consistent output in daily use.
