The unit can be used with additional ASPEN processors to add additional inputs and outputs. Setup and adjustments can be made using the control panel software or the front panel LCD interface. Inputs and outputs appearing on the LCD have been consolidated into logical groups to simplify navigation.\u003c\/p\u003e \r\n\u003cp\u003eThe far end audio signals in a conference participate in the same manner as local microphones connected to the processor. Three sites connected via two codecs and a telephone line can be bridged into a single conference as seamlessly as local microphones.\u003c\/p\u003e \r\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \r\n\u003cul\u003e \r\n  \u003cli\u003eQuad-reference Wideband Acoustic Echo Canceller supporting 3-way Bridging\u003c\/li\u003e \r\n  \u003cli\u003eTwo maximum speed grade, 4th generation SHARC® processors\u003c\/li\u003e \r\n  \u003cli\u003eDual Codec interfaces\u003c\/li\u003e \r\n  \u003cli\u003eTCP\/IP Ethernet Addressable\u003c\/li\u003e \r\n  \u003cli\u003eFully integrated with ASPEN digital matrix\u003c\/li\u003e \r\n  \u003cli\u003eAdaptive Proportional Gain Automatic Mixing at the Matrix Crosspoints\u003c\/li\u003e \r\n  \u003cli\u003eThird Octave Noise Filter on each channel\u003c\/li\u003e \r\n  \u003cli\u003eSigma-delta class-D audio power amplifiers\u003c\/li\u003e \r\n  \u003cli\u003eBuilt-in 8 in\/12 out ASPEN mixer with full signal processing on all inputs and outputs\u003c\/li\u003e \r\n\u003c\/ul\u003e\u003cbr\u003e\u003cp\u003eThe ASPEN AEC (acoustic echo canceller) provides new and advanced algorithms developed to address the need for a single acoustic echo canceller that could handle the challenges of multi-site bridging and an unlimited number of microphones. The AEC converges very quickly, then continues to increase the cancellation depth at every opportunity as a conference continues. Cancellation depth will increase even with brief signal peaks from the far end, and convergence will never be lost with any type of signal or in double talk situations.\u003cbr\u003e \r\n  The AEC in combination with the patented gain proportional mixing algorithm* provides outstanding audio quality without echo heard at the far ends.\u003c\/p\u003e \r\n\u003cp\u003eSignals from the far ends of the conference are routed to the local sound system also to a final mix that is used as a reference signal by the AEC. Audio from the local microphones (which includes far end audio from the local loudspeakers) is routed to the AEC via a second final mix for cancellation of the far end signals. After processing, the output of the AEC is routed back to the far ends through the matrix.\u003c\/p\u003e \r\n\u003cp\u003eThe proprietary noise reduction filter used in ASPEN processors is a third octave dynamic processor which is very effective when applied to the far end Codec and telephone line signals when poor connections occur.\u003c\/p\u003e \r\n\u003cp\u003eAn ethernet port is provided for setup and control via standard network connections, and an RS-232 port is provided for use with remote control systems. The design allows simultaneous, multi-point third party control.\u003c\/p\u003e \r\n\u003cp\u003eA two channel power amplifier is included for loudspeakers in the local sound system. The power amplifier is driven by final mix outputs from the matrix and has a full set of signal processing, including parametric EQ, compressor and limiter. Class-D amplification is implemented with a late generation component that provides exceptional efficiency, low heat, excellent audio performance and cannot be damaged by wiring errors.\u003c\/p\u003e","brand":"Lectrosonics","offers":[{"title":"Default Title","offer_id":48411378964,"sku":"692268","price":4564.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1203\/4576\/products\/c7d5f3d4842d05a7b1a0d3808a77d4dc.jpg?v=1502898268","url":"https:\/\/sg-2111.myshopify.com\/products\/lectrosonics-spntwb-aspen-series-wideband-bridging-conference-interface","provider":"SG_2111","version":"1.0","type":"link"}
