Summary of Contents for Rocktron HUSH 2X

  • Page 1 HUSH 2X Instruction Manual...
  • Page 2 Compliance Your HUSH 2X pedal has been tested and complies with the following Standards and ™ Directives as set forth by the European Union: Council Directive(s): 89/336/EEC Electromagnetic Compatibility Standard(s): 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.
  • Page 3 Precautions Refer all service to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply or plug is damaged, liquid has been spilled or objects have fallen into the apparatus or if the apparatus has been exposed to rain or moisture, does not operate normally or has been dropped.
  • Page 4 HUSH unit. You get total HUSH control both in front, and in the effects loop, of your amp! The HUSH 2X will also allow you to use one HUSH circuit before, and another after, a single pedal or with two different pedal chains on your pedal board/rack drawer.
  • Page 5 The HUSH will give you the same great HUSH noise reduction used by thousands of high profile artists for years! The switches on the HUSH 2X controls On/Off status of each channel as shown by the LED indicator. The HUSH 2X runs on a 9V Alkaline battery, or may also be powered by Rocktron’s DC OnTap Universal Power Supply adaptor.

  • Page 7 Descriptions continued..CHANNEL 1 - THRESHOLD Control determines the minimum input level at which the HUSH filter and downward expander will begin to operate. Setting this control too high will result in a loss of sustain, as notes will tend to die out much faster than they should.
  • Page 8 Descriptions continued..CHANNEL 2 - THRESHOLD Control determines the minimum input level at which the HUSH filter and downward expander will begin to operate. Setting this control too high will result in a loss of sustain, as notes will tend to die out much faster than they should.
  • Page 9 9VDC Input - This input jack requires 9VDC from the Rocktron DC OnTap power supply (sold separately). BATTERY COMPARTMENT (not shown in photo) - The battery compartment is found on the back/ bottom of the HUSH 2X. Use a 9V battery.

  • Page 13 Setting the THRESHOLD controls just above the level of the noise causes the HUSH 2X to begin to decrease the output level so that the noise is never heard. The HUSH 2X incorporates the latest advancements in HUSH noise reduction technology.
  • Page 14 HUSH Information When downward expansion begins, the VCA acts like an electronic volume control and gradually begins decreasing the output signal relative to the input signal. For example, if the input signal were to drop below the threshold point by 10dB, the output would drop approximately 12dB.
  • Page 16 The Variable Integrated Release (V.I.R.) technol- ogy 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 expan- sion 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.
