Introduction Dear customer, thanks for using the Atmos system.
Atmos – the complete surround miking preamp The Atmos is a fully-featured stand-alone surround miking preamp for surround productions in any known format. The Atmos system operates fully analog to ensure independence from any storage or transmission format. Atmos controller The Atmos is equipped with five matched high precision microphone preamps featuring SPL‘s triple gain stages to capture the superb sound of Brauner‘s mic array microphone in the most transparent, noiseless and uncoloured way.
Installation The Atmos unit should not be installed near units which produce strong magnetic fields or extreme heat. Do not install the units directly above or below power amplifiers. A main mic array has to be placed the way that the LCR heads of the microphone (those closer to the microphone center/90° angle) are facing the sound source. Be sure to place the microphone as high as necessary to avoid ground reflections and comb filtering effects.
Control Elements 5-Channel Preamplifier Control The central, 5-layer gain control allows for adjusting preamplification values between 18 and 72 dB. It controls all channels simultaneously. Switches: HP and PAD The PAD switch reduces input level by -25 dBu. The HP switch activates a high pass filter at 70 Hz, e.g. to eliminate subsonic frequencies. Outputs For recordings of the preamplified signals recording devices like a multitrack recorder can be connected either to the XLR or DB 25 outputs.
Specifications Frequency range Mic Out @ 18 dB Gain: 10 Hz-180 kHz (+/-3 dB, Phase –2°) CMRR 18 dB Gain: 34 dB Gain: 60 dB Gain: w.
