Digital switching system BFS-V01

BFS-V01 is a device that contains a number of features related to digital processing of audio signals. Its main function is to measure in real time the audio signal level present at the two XLR connectors for input, one regarded as preferential and the other as a reserve. The two levels are constantly compared with a preset threshold and in the case of the absence of one of the two an alarm is triggered. Upon the occurrence of the alarm condition BFS-V01 is able to operate to switch the audio output on the channel considered as reserve. Both the intervention time and the recovery can be set through the front keypad of a minimum of 100 ms and a maximum of 59 seconds. On the front panel of the BFS-V01 there are also two bar graphs of precision that can view the two input audio level. These bargraph are calibrated according to DIN 45406. The scales used for bargraph range from -40 dB to +5 dB according to specification. There is also a scale which expresses the percentage of the level in function of the 100% modulation at 0 dB. Also on the front panel is an alphanumeric display and a keypad for access to configuration parameters. It is also possible to perform the switching output of the two channels by means of two keys with LEDs indicating which of the two signals is in transit. The dynamic range of the BFS-V01 is 96 dB with a bandwidth that extends from 20 Hz to 16 kHz with frequency linearity of the measure in between + / - 0.5 dB. The signal level of the two signals is amplifiable in such a way as to align the chain to 0 dB. The range of amplification ranging from a minimum of -10 dB to + 30 dB.
