The QSC Q-SYS QIO-TEL2 is a networked analog telephony I/O expander designed to add POTS connectivity to Q-SYS systems. It provides two analog telephone lines through standard RJ-11 connectors, allowing Q-SYS to integrate with PSTN subscriber lines, PBX phone systems, paging systems, and other analog telephony applications.
The QIO-TEL2 separates local I/O from Q-SYS processing hardware, allowing analog telephone connectivity to be positioned where it is most convenient. It integrates directly with Q-SYS Designer Software and Q-SYS Reflect for streamlined configuration and management.
For flexible deployment, the QIO-TEL2 supports Power-over-Ethernet and can also use 24 VDC auxiliary power. Up to four QIO Series devices can be daisy-chained on a single network run when local DC power is used. The compact enclosure can be surface- or wall-mounted, or installed in a standard 1RU rack using the optional QIO-RMK rack mounting kit.
