SPECIFICATIONS
ISDN Mode: Available audio coding algorithms:- G.722 Statistical/64 kbps. Bandwidth: 20 Hz - 7.5 KHz. - G.722 H221/242/64 kbps (include Channel Auxil. Dat). Bandwidth: 20 Hz - 7,5 KHz. -
G.711/64 kbps.A and μ Law, for connection with standard telephone numbers. -
E-ISDN Protocol
Analogue Telephone Line Mode: Digital Hybrid with Frequency Extender and Echo Cancellation (64 dB rejection), dial pad for tone or pulse. Bandwidth: - without Extender: 300Hz-3.300 Hz.- with Frequency Extender: 50 Hz-3.050 Hz.
4 Wire Interface:Full bandwidth (20 Hz-20 KHz). Wheither the unit is used as an Audiocodec on ISDN or as a portable Telephone Hybrid on PSTN, the transformer balanced 4W input/output is always available, being operative to use it simultaneously with any of the two modes. The return input has a level adjustment (Trim) and it is permanently routed to the headset outputs. Therefore it can be used for the connection of other Auxiliary signals that could be required to be monitored by the reporters, such as Guides, Cue, P. A., International Sound, etc. The Aux out has also a mix control for the send and return signals (SOURCE), in this way increasing the possibilities of the equipment of the equipment which can be used as per the following example:- As a conventional 4W circuit, or a pre-mixer, setting the associated control knob SOURCE in TX position. - As a recording output, setting the associated control knob SOURCE in an intermediate position TX/RX. This way, both program and return signals are available at the output.- As an auxiliary output for the digital hybrid, setting the associated control knob SOURCE in RX position. This way the unit can be connected to other equipment or to a loudspeaker in order to use the hybrid as a hands-free telephone.
MIXER INPŁTS:- Two Microphone inputs. - One selectable Micro/Line input. Independent level control. Input connectors are Neutrik XLR-COMBO, allowing the connection of either XLR-3 or 1/4” JACK connectors. The mixer signal treated with an analogue compressor/limiter to avoid clipping in the digital stages.
HEADPHONE OUTPUTS:- Two Headphone Outputs with independent level controls. - Equipped with a mixing control of the signals to monitor, thus allowing the continous adjustment from only Program go to Return signal, i.e. any mix between both.- Monitoring of the Auxiliary Input, with Trim level.
OTHER FEATURES:- Acoustic and optical signalling of the incoming calls either in ISDN or Analogue Telephone Lines. - Alphanumeric Phonebook with up to 256 entries. - Menu configuration using only two buttons.- Dialling with sub-addressing capability. - Software upgrade available through Flash-RAM technology.
