    We value your suggestions and your comments! Please pay close attention to how you connect your CL44 to your system. Improper grounding is the most common cause of noise problems found in studio or live sound systems. We urge you to at least scan this manual before hooking up your CL44 to become familiar with its features and various applications.

    2.1 FRONT PANEL BASIC LAYOUT Notice that the front panel is divided into four identical sections. These are the four signal processing channels of the CL44. Each channel contains: Compressor/Limiter Lo Filter Compander Gain (Output Control) Link & Bypass Control Optical and Auto Mode 2.2 COMPRESSOR/LIMITER CONTROLS...

    Limiter The limiter on the CL44 has a fixed compression rate of greater than 20 to 1, and a fast fixed attack and release. The limiter knob allows you to set the threshold level.

    (normaled). When a connector is inserted into this jack, the signal path is broken. If you have inserted a tip-ring-sleeve connector, the input signal is sent back out of the CL44 via the ring of the connector. This signal can then be processed by an equalizer for example to reduce sibilance (de-essing) in a vocal track.
  • Page 10 The power jack on your CL44 accepts a standard IEC cord like those found on most computers and professional recording equipment. Your CL44 contains a custom built in power supply, no wall wart. This way you can be assured of clean power...

    To set up for a vocal take, insert a channel of your CL44 into the same channel as the microphone on your mixer. If your mixer has an insert point, insert the compressor there. If you don't have an insert point you will have to place the compressor after your mixer's bus-output or whichever output you're using by coming out of your mixer to the input of the CL44;...
  • Page 12 Limiting is defined as compressing with a ratio of greater than ten to one. It is like an imaginary ceiling for the level of a signal. On your CL44, limiting can occur either when the ratio knob is fully clockwise or when the limiter knob is set to an appropriate level (for example at ‘...
  • Page 13 Stereo Compressing/Limiting The linking feature of your CL44 will allow you to have up to two stereo linked pairs of compressor/limiter. If you read the section in chapter two on the link function, this is easily achieved by pushing in the link button creating a stereo pair.

  • Page 15: A Word About Compression

    A Word About Compression Punch, apparent loudness, presence- just three of many terms used to describe the effects of compression/limiting. Compression and limiting are forms of dynamic range (volume) control. Audio signals have very wide peak to average signal level ratios (sometimes referred to as dynamic range which is the difference between the loudest level and the softest level).

  • Page 16: Troubleshooting

    Most dynamics processors use a 1/4” TRS Y shaped insert cable to connect to a console. The CL44 is designed to connect to a console using one 1/4” TRS cable. A 1/4” TRS Y male to dual female cable may need to connect the CL44 to an existing audio snake.
