Behringer SNR2000 Manuel D’Utilisation

DENOISER SNR2000

4.7 The single-ended principle

In contrast to conventional noise reduction systems using compressors and expanders, the DENOISER is

purely a single-ended system. Single-ended means that the noise reduction system is not based on a

process combining both record and playback (encoding and decoding), but is simply inserted into the

signal chain after the signal that is going to benefit from noise reduction. The noise reduction capabilities

of the BEHRINGER DENOISER are based on bandwidth limiting by means of a dynamic low-pass filter and

broadband noise reduction during music pauses by a downward expander.
Thus, the DENOISER can be used for any program source, since it processes during playback. Due to this

outstanding feature, virtually any noise can be removed!

5. INSTALLATION

5.1 Rack mounting

The BEHRINGER DENOISER fits into one standard 19" rack unit (1 3/4"). Please allow at least an additional

4" depth for the connectors on the back panel.
Be sure that there is enough space around the unit for cooling and please do not place the DENOISER on

high temperature devices such as power amplifiers etc. to avoid overheating.

5.2 Audio connections

As a standard, the BEHRINGER DENOISER is installed with electronically servo-balanced inputs and outputs.

The circuit design features automatic hum rejection for balanced signals, permitting trouble-free operation

even at highest operating levels. Externally induced power-line hum, etc. is thus suppressed effectively. The

automatic servo function recognizes the presence of unbalanced connectors and adjusts the nominal level

internally to avoid level differences between the input and output signals (6 dB correction).

Please ensure that only qualified persons install and operate the DENOISER. During installation

and operation the user must have sufficient electrical contact to earth. Electrostatic charges

might affect the operation of the DENOISER!
