User manual ART THE LEVELAR

[. . . ] In addition to making signal levels more manageable, it is common practice to apply compression or limiting to a signal to make it louder or more "in-your-face". The benefit of using the Levelar for these applications is in its design. 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. [. . . ] In its "out" position, the Levelar is bypassed and signal runs from the input jacks to the output jacks with no processing. Use the Active/ Bypass switch when setting the Levelar's output level to achieve unity (no boost or cut) gain. Unity gain is achieved when the active level is the same as the bypassed level. Limit/ Comp Switch In its "out" position, the Levelar's compression ratio is an active 2. 3:1 ratio. This means that for every 2. 3dB over the threshold the input signal rises, the Levelar's output will change by 1dB. This is a very mild and musical compression ratio which is ideal for smoothing all types of signals. In its "in" position, the Levelar's compression ratio is greater than 6:1. This is typically called "soft limiting" as it allows only a 1dB change in signal level for any signal reaching over 6dB over the set threshold. This setting is ideal for applications where exceeding a set level is not desirable (mixing, popping bass, etc. ). Auto/ Fast Switch The position of the Auto/ Fast switch selects the release characteristics of the Levelar. The "out" position allows the Levelar to recover quickly once the signal falls below the threshold. The "in" position allows the Levelar to adjust itself depending on the characteristics of the input signal. Use the "fast" setting when the signal has repetitive, consistent characteristics (kick drum, snare, vocals, etc. ). The Levelar is powered by an external 9VAC adapter. Always make sure the output plug is securely plugged into the rear of the Levelar, and that the adapter is held firmly in an electrical outlet. There is a "U" shaped knock-out above the power jack which is designed to have the power cord looped into to prevent the cord from coming unplugged. Never operate the Levelar or AC adapter in the rain or in wet locations. If the AC adapter's cord is ever cut, discontinue use and replace the adapter with a new one. Unplug the adapter when the Levelar is not in use.
