Threshold -1. 1dB Ratio 3. 8:1 Attack 0. 002mS Release 38mS Perc. 1 SNARE/KICK - Allows the first transient through and compresses the rest of the signal giving a hard snap up front with a longer release. Threshold -2. 1dB Ratio 3. 5:1 Attack 78mS Release 300mS 2 L/R (Mono) OVERHEAD - A low ratio and threshold gives a ` contour to even out the sound from overhead drum mics. Low fat' end is increased and the overall sound is more present and less ambient. More ` boom'less ` room' . Threshold -13. 7dB Ratio 1. 3:1 Attack 27mS Release 128mS Fretted 1 ELECTRIC BASS - A fast attack and slow release to tighten up the electric bass and give you control for more consistent level. PRESONUS Threshold -4. 4dB Ratio 2. 6:1 Attack 45. 7mS Release 189mS 2 ACOUSTIC GUITAR - This setting accentuates the attack of the acoustic guitar and helps maintain an even signal level keeping the acoustic guitar from disappearing in the track. Threshold -6. 3dB Ratio 3. 4:1 Attack 188mS Release 400mS 3 ELECTRIC GUITAR - A setting for ` crunch' electric rhythm guitar. A slow attack helps get the electric rhythm guitar up close and personal and gives punch to your crunch.

Threshold -11. 9dB Ratio 1. 8:1 Attack 0. 002mS Release 85mS 11 PRESONUS 3 ORCHESTRAL - Use this setting for string ` pads' and other types of synthesized orchestra parts. It will decrease the overall dynamic range for easier placement in the mix. Threshold 3. 3dB Ratio 2. 5:1 Attack 1. 8mS Release 50mS Limit 1 MONO LIMITER - Just as the name implies. A hard limiter setting (brick wall) ideal for controlling level to the 2 track mixdown deck or Mono output.

Threshold -4. 6dB Ratio 2. 4:1 Attack 7. 2mS Release 93mS PRESONUS 2 PUMP - Make the COMP16 ` pump up the prime' A setting for . This effect is good for snare drum to increase the length of the transient by bringing the signal up after the initial spike. If the EQ3B does not work immediately, you may want to try changing the jacks that are plugged into the input and output of the unit. 15 PRESONUS BASIC OPERATING PROCEDURES Setting Compression Amount Your COMP16 was designed with a fixed threshold mode of operation. This differs from other compressors in the fact that there is no threshold control. This offers the unique ability to immediately hear the sometimes subtle differences between presets which each have unique threshold settings. In setting the compression amount, always begin with the Input control all the way counter-clockwise (-20dB), and slowly increase the input until the Gain Reduction meters begin to register the compression activity. The more you crank up the Input the more compression your signal will experience. You should also frequently remove the compression from the signal using the Bypass button to listen to the changes in your sound. In modern recording practice, it is customary to adjust the Output control such that the Input and Output level are of equal amounts according to the Output/Gain Reduction meter. This gives you an equal level output so that you can switch processing in and out to compare difference. PRESONUS 3. 1 EQ3B FRONT PANEL BASIC LAYOUT The front panel on the EQ3B is divided into three sections. These are the three bands of equalization: There is a frequency selection knob (Hz), gain/gain reduction(dB) (amplitude) knob and a Q control. The frequency selection knob (Hz) allows the user to choose the center frequency of that band of the EQ. The Q knob allows the user to alter the width of the frequency being adjusted. Q is defined as the ratio of the center frequency divided by bandwidth. An example of use of high Q would be a " Notch Filter" A Notch Filter is used to remove a small .
