It includes a total of 12 analog inputs (8 mic/line level inputs and 4 line level inputs), 12 analog outputs, and 4 digital expansion busses. Acoustic echo cancellation (AEC) and noise cancellation can be applied to each of the 8 mic/line level inputs, and each of these inputs can then be sent to one of the two internal automatic microphone mixers. The system also contains a 25 x 18 main matrix, and four 7 x 3 submatrices. The 25 x 18 main matrix has the following inputs: input channels 1-8 (gated or ungated), input channels A-D, the internal signal generator, and 3 mixes of each of the four digital busses (3 mixes times 4 busses equals 12 inputs). The 25 x 18 main matrix has the following outputs: outputs 1-8 and A-D, AEC reference 1 and 2, and W, X, Y, and Z outputs to the digital expansion bus. The EF2280 has 24 bit resolution, 32-bit floating point computation, and a 48 kHz sampling rate. Polycom's proprietary noise cancellation on each of the 8 mic/line inputs helps to keep overall ambient noise to a minimum. Polycom echo cancellers are the only ones on the market to feature this patent pending technology. Noise cancellation filters out ambient background noise such as noise from heating, ventilating and air conditioning (HVAC), LCD projectors, and road noise. Our noise cancellation technology is not a noise gate. It actually removes noise. Therefore, it enhances the operation and improves the sound quality of an automixer, for example, by preventing it from bringing the noise level up and down when microphones are gated on and off. By cancelling the noise picked up by each microphone, the overall signal to noise ratio (SNR) is preserved. The result is crystal clear speech over a greater decibel range than any other echo canceller. That means reduced listener fatigue and a higher quality audio conference.
