User manual ART THE ACOUSTIC

[. . . ] By utilizing opto-electronics, the Levelar allows you to add more compression without sounding like you're squashing the daylights out of the signal. Unlike typical compressors that use VCA's to control level detection, the Levelar is very musical. The nature of its operation is much like the way your eye adjusts to light. Just as your eye transparently adjusts to changes in light, the Levelar adjusts to changes in signal level. Connections: It's easy to interface the Levelar with other equipment. [. . . ] Use the unbalanced 1/4" jack for sending your signal to amps, processors or other unbalanced configurations. Use the XLR output to send signals to equipment which accepts XLR connections. Both outputs may be used at the same time. threshold (adding more compression to a signal). Turning this control clockwise raises the threshold. Setting the threshold control is dependent on the input signal. The output from a guitar might be -20dB to -10dB, where the level from an insert on a console might be -5dB to +10dB. The easiest way to set the threshold control is to start with the control fully clockwise. Slowly turn the control counter-clockwise (lowering threshold) until you see the threshold LED light. Now adjust the control (either lower or higher) until you have the amount of compression you desire. Active/ Bypass Switch The Active/ Bypass switch must be pressed "in" for the Levelar to process a signal. In its "out" position, the Levelar is bypassed and signal runs from the input jacks to the output jacks with no processing. @ 700ma (typ) Output Control The Output control sets the output gain of the Levelar. When the control is fully counterclockwise, the output level of the Levelar is attenuated by -83dB. Turning the control clockwise adds gain (sometimes called "make-up" gain). Since levels can be decreased when compression is applied, the Levelar has the ability to apply gain to bring the processed signal back up to unity (same as input level). To properly set the output level, adjust the control while switching between Active and Bypass. When these two levels are equal in volume, the output control is set properly. Gain Reduction Meter The four-LED meter is provided to give a visual indication of how much compression is taking place. The Threshold LED will light when the input signal reaches the set threshold level. The remaining three LEDs indicate how much the signal is being compressed. Their values are -2dB, -3dB and -6dB. A R T retains a policy of constant product improvement. Therefore, specifications are subject to change without notice. [. . . ] 1) Be sure that the unit is the cause of the problem. Check to make sure the unit has power supplied, all cables are connected correctly, and the cables themselves are in working condition. 2) If you find the unit to be at fault, write down a description of the problem, including how and when the problem occurs. 3) Call A R T's Customer Service Department to obtain a Return Authorization (RA) number.
