SPL Atmos

The new SPL Atmos system is a complete, system independent surround miking system either including the ASM5 microphone with the superb Brauner VM1 capsules or the INA5-R made by Microtech Gefell, which is perfectly suited for in- and outdoor applications.

Ten years of experience in surround miking technology result in a new reference system for surround sound in highest definition. The new Atmos Controller incorporates the five channel, remotely controllable preamplifier section, a LFE channel composer with level control and a headphone monitor. The Controller is now focused on basic features to reduce costs and complexity dramatically for a pure, high definition preamp/microphone setup.

The preamplifier section 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 ASM5 or INA5-R 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.

The ASM5 is based upon five selected and matched VM1 large diaphragm capsules. The positions of the all microphone heads are variable +/-90 degrees.

The INA5-R is made by Microtech Gefell with five matched M930 microphones. Each single mic can be adjusted as well to find a perfect individual position for each capsule.

Individual microphone solutions can be connected to the Atmos controller as well. The Atmos provides balanced XLR and DB25 outputs (parallel).
