from our Demo/microphones not included The preamplifier section of the Atmos ensures a homogeneous preamplification over all channels for a coherent imaging of rooms and source widths. The high precision preamplifiers are based upon SPL‘s Triple Gain Stage to capture the superb sound of the microphones in the most transparent, noiseless and uncoloured way. In the first stage, a Lundahl transformer provides galvanic isolation and a passive 1:5 preamplification. Amplification and DC offset compensation with SPL‘s ServoDrive circuitry are realized by the followoing two stages.
Thanks to the included Pentarray, five individual microphones can be easily connected in a perfect surround setup and connected with just one cable.
