  • Page 3: I) Introduction

    ELOP Compressor, an EQ section and a fast FET Brickwall Limiter. Musical. Flexible. Forgiving. These three concepts were my main goals in designing the CORE channel strip. To give the musician tools he or she really needs, without needless complication. Why is this important? Because recording has become more complicated than ever! Computers, plug-ins, and software can easily distract from creating your music.

    2. Object and Liquid Entry – Care should be taken so that objects do not fall, and liquids are not spilled, into the enclosure through the openings. 3. Heat & Ventilation – When installing The CORE in a rack or any other location, be sure there is adequate ventilation. Improper ventilation will cause overheating, and can damage the unit.

    Final Output Direct Input As the signal flow in the CORE is from right to left, we'll describe the functions in that order as well: 4. Input Section The INPUT LEVEL control is an input attenuator. It functions like a variable pad.

  • Page 6: Optical Compressor

    ® Compressor ELOP ® ELOP Compressor utilizes our famous circuit topology as ® ® , and is also similar to the found in the VOXBOX ELOP and SLAM limiters. The COMPRESSION (Threshold) control determines at what level the compressor begins to act. Clockwise rotation makes the compressor reduce the signal.

    O/P 1- shows the audio level of the DIRECT OUTPUT of the preamplifier and compressor section. O/P 2 - shows the MAIN OUTPUT audio level of the CORE. GR - indicates the amount of COMPRESSOR gain reduction in decibels. This position stays at “0 VU” when there is no gain reduction and moves to the left to show the amount of compression.

  • Page 13 Note-1: if you do not have enough output level coming from your oscillator, then increase the signal level coming into the CORE by adjusting the INPUT LEVEL ATTENUATOR control. Bring up the input level attenuator until you have a reading of +21dBu at the output XLR “OP2”.
