TOA launches second phase of N-8000 series IP network intercom products

TOA Electronics, Inc. is expanding their N-8000 Series IP Network Intercom with several new options for increased system flexibility. The system expansion begins with the new N-8500MS IP Multi-function Master Station, which has a built-in Ethernet connection for direct network connection, a 32 character alphanumeric LCD display, and handset and speed dial functions. The new N-8540DS IP Flush-Mount Door Station also connects directly to the network and includes a vandal-resistant call-switch and control output for door release.

New two-wire stations in the series include the N-8030MS Flush-Mount Hands-free Master Station and N-8040DS Flush-Mount Vandal-Resistant Door Station. For custom station applications, TOA offers the new N-8031SB Hands-free Master Station Board Unit and the N-8050SB Hands-free Substation Board Unit. The new economy N-8010EX IP Intercom Exchange, featuring one speech link, is now available as an alternative to the four-link N-8000EX IP Intercom Exchange. Finally, the N-8000MI Multi-Interface features telephone interface, BGM input, paging outputs, control signaling plus functions as an interface to legacy TOA EXES intercom systems.

The N-8000 Series IP Network Intercom provides flexible communication for up to 1280 stations on existing corporate local and wide area data networks. Built on TOA’s proven NX-100 network audio technology, the new IP Intercom products occupy minimal network bandwidth for station-to-station calls and can be controlled and monitored through software or by a web browser. Programmable system functions include 160 paging zones, time-based call forwarding and scan monitoring. Two-way hands free communications is also possible through an innovative ambient noise sensing function.

The N-8000 Series IP Network Intercom Systems received the 2006 Innovations in Technology Award in the category of Security/Fire/Life Safety at the 2006 NSCA Systems Integration Expo in Las Vegas.

Helpful Hints

Headphones impedance
The two important electrical specifications for a pair of headphones are the impedance of the phone transducer itself and its on-the-ear sensitivity. So-called low impedance headphones may vary from 75 ohms up to about 150 ohms. Phones in this impedance range may be directly plugged into the headphone jack routinely found on recording and playback equipment. Higher impedances, such as 600 ohms, are more useful in studio installations where many units may be wired in parallel for studio monitoring applications. Headphone sensitivity is usually stated as the in-the-ear sound pressure level produced by one milliwatt (mW) of audio input. Typical sensitivity ratings of AKG headphones run from 88 dB per mW to 105 dB per mW. You can see that very little power is needed to drive a stereo headphone pair to very high listening levels.
