Frequently Asked Questions
How does the CMX DI-9723P connect to an existing enterprise network?
The CMX DI-9723P connects directly into any standard corporate, campus, or facility LAN switch via an RJ45 Ethernet port using CAT5e or CAT6 cabling. It communicates seamlessly over ARP, TCP/IP, UDP, ICMP, and IGMP protocols, allowing it to receive background music streams, zone paging announcements, and emergency voice alarm broadcasts from central CMX IP PA management software without dedicated speaker wire runs.
Can the DI-9723P operate on standard Power over Ethernet (PoE)?
Yes. The DI-9723P is fully compliant with the IEEE 802.3at PoE+ standard, allowing audio signals, network control, and electrical operating power to be delivered through a single Ethernet cable. For installations using standard network switches or non-PoE ports, the speaker also features a standard 220V–240V AC power connection.
Is the CMX DI-9723P sold as a single unit or a stereo pair set?
The DI-9723P is supplied as a complete 2-speaker system comprising one active master speaker (housing the IP streaming processor, DAC, and 20W + 20W Class-D amplifier) and one matching passive slave speaker (DI-9723F). The master speaker powers the slave speaker via a dedicated Euroblock connection terminal for balanced stereo sound reinforcement.
Can local room sources like microphones or interactive flat panels be connected?
Yes. The active speaker side panel features a 6.35mm dynamic microphone input and dual RCA AUX line inputs. Presenters can connect teacher wireless mic receivers, interactive touchscreens, or laptop computers locally with full rotary tone control (Bass, Treble, Echo, and Volume) while network emergency announcements maintain top priority.
How many IP zones can be managed simultaneously across an installation?
Through CMX central IP audio server software, the system supports scaling up to 1,200 individual IP zones. Each DI-9723P speaker pair can be designated as an independent zone or grouped into multi-classroom, multi-floor, or campus-wide broadcast clusters with zero signal degradation.
