TM MicroHUSH Instruction Manual
Compliance Your MicroHUSH™ pedal has been tested and complies with the following Standards and Directives as set forth by the European Union: Council Directive(s): Standard(s): 89/336/EEC Electromagnetic Compatibility EN55013, EN50082-1 This means that this product has been designed to meet stringent guidelines on how much RF energy it can emit, and that it should be immune from other sources of interference when properly used.
Introduction Got hiss? Get HUSH! The MicroHUSH is Rocktron’s world famous noise reduction in a micro chassis that will take up less space on your pedalboard. The MicroHUSH will wipe out hiss, unwanted feedback and pickup buzz by providing up to 65dB of signal cleanup, while your music signal integrity remains unaffected.
Introduction continued.... Here’s more HUSH tips: For maximum noise reduction results, place the MicroHUSH after your distortion and modulation effects (chorus, flanger, phaser, etc.) but before any delay or reverb effects.
Descriptions
Descriptions continued......... 1 THRESHOLD Control - This control determines level of attack to cause the HUSH to activate. Attack is measured in time. Threshold is measured in dB or by the voltage/level of the signal. 2 9VDC Power Jack - The MicroHUSH requires 9VDC power to operate (not included/sold separately). This 2.1mm power jack (Negative Tip/Positive Barrel) provides 9VDC power to the pedal. We recommend the Rocktron DC OnTap Univeral 9V power supply.
Typical Connection
HUSH Information In most applications, the signal from an instrument being played is much louder than the noise level. Therefore, much of the noise is not heard when an instrument is being played. However, when you stop playing or let a note decay, the instrument level drops below the noise level and the noise becomes much more audible. Setting the THRESHOLD controls just above the level of the noise causes the MicroHUSH to begin to decrease the output level so that the noise is never heard.
HUSH Information The Variable Integrated Release (V.I.R.) technology contained in each HUSH circuit automatically adjusts the release rate of the expander based on the dynamic decay rate of the incoming signal. If the input signal stops suddenly, downward expansion will occur rapidly (similar to a gate). If the input signal decays slowly, expansion will occur slowly without disrupting the dynamic decay of the input signal.
