Comrex Matrix - POTS/ISDN Protable + Rackmount Interface Bundle - Used This used Comrex Matrix provides both ISDN and PSTN full duplex links of 15kHz, and interfaces to the cellular network to provide enhanced audio quality via a mobile phone connection. Fully compatible with all modes of the Vector and HotLine PSTN codecs, the Matrix provides a two-channel audio input mixer with additional tape input, comprehensive call handling and automatic interfacing to Matrix, Vector and HotLine codecs. The Matrix accepts a plug-in ISDN module that provides three options for getting audio to and from a remote location via ISDN: Industry-standard G.722 on a single bearer; ISO/MPEG Layer III 15kHz bandwidth audio (also on a single bearer); and Comrex Turbo G.722 on two bearers, giving 15kHz full duplex audio with just a 6ms delay. The Matrix can either connect directly to a suitable cellular telephone but also accepts a plug-in interface for a PCMCIA modem for a GSM mobile phone, over which it can send and receive surprisingly good audio quality via the cellular phone network. Being a plug-in module, the Matrix will be able to take advantage of new developments in cellular services as and when they become available, preserving the value of your investment.SpecificationsMatrix Rackmount Specificatoins Audio in: 3-pin XLR female (1) Audio out: 3-pin XLR male (1) Tel Line and Tel Set: RJ11C 6-pin modular jacks (2) Contact Closures: 1/8" 2-conductor mini-jacks (4) Multipurpose Port: 9-pin D connector (1) Audio Input: -10, 0, +4 dBu (via jumpers to +8) @ 20K ohms Audio Output: -10, 0, +4 dBu (via jumpers to +8) @ 100 ohms Telephone Line Out: -9 dBm @ 600 ohms Internal supply: 120/240 VAC 60/50 Hz Size: 19" W x 8" D x 1.75" H Weight: 5.5 lbs Matrix Protable Specificatoins Audio In: 3-pin XLR female (2) Tape In: 1/8" 2-conductor mini-jack (1) Audio Out: 3-pin XLR male (1) Headphone Out: 1/4" stereo phone jack (1) Tel Line and Tel Set: RJ11C 6-pin modular jacks (2) Contact Closures: 1/8" 2-conductor mini-jacks (2) Auxiliary Data Port: DB-9 connector (1) Accessory Connection: 25-pin D connector (1) Mic Input: -85 to -40 dBu Line Input: -10 to +10 dBu Tape Input: -10 dBu (fixed) @ 10K ohms Line Level Out: +12 dBu maximum @100 ohms Headphone Out: .5 watt Telephone Line Out: -9 dBu @600 ohms External Supply: 24 V Size: 9.5" W x 10" D x 3.5" H Weight: 2.5 lbs
