SPL Atmos Description
The new Atmos system is a complete, system independent surround miking system ,
ideally suited for the ASM5 indoor 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 SPLs 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 SPLs 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.
For detailed information please contact the respective manufacturers. Individual microphone solutions can be connected to the Atmos controller as
well. The Atmos provides balanced XLR and DB25 outputs (parallel).
