    The ‘Peak’ control operates independently from the compressor/limiter section of the CX335. It has the advantage of allowing the user to directly set an absolute limit on the maximum output level, however it has the disadvantage of not sounding as transparent as the compressor.
  • Page 6: Intelligent Limiting

    20:1 or higher if you require compression and limiting. With normal programme level running through the CX335, rotate the gain control so that the output level on the left and right channel VU meters measures about the same in bypass mode as it does with the compressor operational.

    'Instant-attack' peak limiter, accurate and informative metering, and remote control of the compressor side chain. The CX335 may be used in either balanced or unbalanced systems with no internal re- configuring. Because the CX335 compressor offers a choice of traditional hard-knee, ratio style compression or soft-knee compression, it is equally adept at creative work and unobtrusive level control.

    Another feature of the CX335 is a highly effective peak limiter that allows the user to set an absolute output level that can never be exceeded. This facility is extremely valuable for speaker driver protection.

  • Page 10: What Is Hard-Knee And Soft-Knee

    Soft-knee gradually changes the ratio as the signal rises above the threshold setting. On the CX335 this change takes place for as much as 10dBs, so the selected ratio is only reached once the signal is 10dB above the threshold setting. This changing ratio is far more musical and disguises the fact that any manipulation of the dynamic range is taking place.
  • Page 11: Gain Requirements

    This compressor limiter section should not be confused with the Peak limiter in the CX335. This is intended to be used as a system failsafe for any high peaks that are still quite high even after some compression has occurred.

  • Page 13 The integral soft-knee feature of the CX335 renders these effects far less pronounced, but this factor should still be taken into consideration when setting up. Although, with the CX335 a higher compression ratio may be used than that of conventional compressors without compromising the sound quality.
