BEA3X-MIC: Precision in Microphone and Line Inputs
Unleashing the Versatility of 8 Balanced Inputs
Exploring the capabilities of the BEA3X-MIC board, which provides 8 balanced microphone or line inputs. Each input is equipped with controllable analogue microphone amplifiers, programmable gain, low cut filters, and phantom power support. Calibrated at 15 dBu at 0 dBFS, with alternative configurations available. We’ll delve into detailed analog audio specifications, including impedance, gain, EIN, THD + Noise, CMRR, dynamic range, crosstalk, hi-pass filter, and conversion. Additionally, we’ll outline the role of the BEA3X-BOB-I8 breakout box for signal expansion, along with the option for greater compactness using the BEA3X-BOB-I16.

Breakout Box
A rack-mountable BEA3X-BOB-I8 breakout box and pre-headed DB26 cables of different lengths are available for the explosion of signals from the DB26 connector to the standard 8 female XLRs.
Alternatively, for greater compactness, a BEA3X-BOB-I16 breakout box can be used for every 2 MIC boards.
