Product Description

1. The Plena feedback suppressor uses a powerful DSP with a patented algorithm to suppress acoustic feedback. It actively filters out unwanted room reverberations using an echo-cancellation and dereverberation algorithm. By adding masked (inaudible) noise to the output signal or by shifting the frequency of the output signal by five hertz the Plena feedback suppressor is able to detect the reverb component of the signal and remove it before feedback occurs. This leaves the original signal intact.Functions The adaptive filter can be switched between fast mode and accurate mode. The fast mode is for situations where the microphone position changes over time such as in a discussion system with multiple switching microphones. The accurate mode is for situations with a fixed microphone position such as on a pulpit where the acoustical environment is more stable. The adaptive filter is allowed to converge more slowly suppressing reverberation components even more effectively. Depending on the acoustical environment and the chosen mode of operation up to 12dB of additional gain is possible before acoustic feedback occurs.The Plena feedback suppressor also features a built-in automatic mixer for the two microphone inputs. In many situations such as on a rostrum a pulpit or a conference table two microphones are used to capture the voice of a moving speaker better even though this increases the risk of acoustic feedback. To counter this the automatic mixer in the Plena feedback suppressor reduces the gain of the microphone with the lowest signal input and increases the gain of the microphone with the highest signal input. This way it tracks the moving speaker for optimum speech intelligibility while maintaining a maximum feedback margin by keeping the combined gain constant. The automatic mixer function remains operational even when the feedback suppressor is deactivated.andbull; Patented feedback suppression algorithmandbull; Suppresses feedback before it occursandbull; Automatically adapts to the acoustical situationandbull; Up to 12 dB additional gain before feedback occursandbull; Balanced line or microphone input with phantom supplyFeaturesDimensions W x D x H430 x 270 x 56 mmWeight3 Kg
