[. . . ] Use the Parameter Up/Down buttons to select the one you want to edit, and then use the Value Up/Down buttons to make an adjustment: · 2 Frequency--select a value between 20Hz and 20Khz. Gain--select a value between -12dB and +6. 0dB. Gain Value · After you make an edit to a Program, you must save those changes to one of the User Program locations. If you select another Program before you do, your edited Program will be lost. For information on how to save an edited Program, see the description of Save mode on page 20. TIP: To disable an EQ band, set its GAIN value to 0 and its Q to anything but HP. · Q--select a value between 0. 25 and 4. 0 octaves. If the Value Down button is held, the values will "race" downward to 0. 25 and stop. However, there are three more values which are accessed by additional presses of the Value Down button: HSH (high shelving), LSH (low shelving) HP (high-pass filter). For definitions of these settings, see page 27. Q Value Note: if a Q value of HP is selected, the Gain parameter is not available. Remember the "doublebutton reset" trick: pressing the Value Up/Down buttons at the same time will reset the selected value to its default. The Band button Press the Band button to select which of the four Bands will be edited. Keep in mind that any changes that were made will be lost if another Program is selected before the edited Program has been saved. The Band button 19 2 Operations Save Mode Program Up Exit Save Mode Save mode allows you to preserve the changes you have made to the EQ curve by saving it to one of the eight User Program locations. From this point: · · · The Value Up/Down buttons select the User Program location into which the edited Program will be saved. Pressing the Page button will exit Save mode without saving the Program and take the speaker to Program mode. Pressing the Save button again will save the edited Program to the selected User program location, and then returns the speaker to Program mode. Any speaker on the same Channel will also save the edited Program to its User bank. As the Program is being saved, the SAVED icon on the display will illuminate for about two seconds. Program Down Save Settings If you attempt to store a Program to a Preset Program location, the ProLinear DSP will automatically store the Program to the same number location in the User bank. 20 Operations 2 Input Level Mode The ProLinear DSP has an extremely useful feature called Input Level mode that can help you optimize the speaker's performance. This mode allows you to measure the level of the incoming signal, which in turn makes it possible to adjust the rear panel Input Level control to its ideal position. In addition to allowing you to achieve maximum signal integrity for an individual speaker, Input Level mode can also be used: 1. To be certain that all ProLinear DSP speakers in the system are at the same level, and 2. To be certain all speakers are operating at an optimal signal-to-noise ratio (SNR). To optimize your setup, you need to send a constant, steady signal to the ProLinear DSP speaker. Most audio engineers would send the unit pink noise, white noise or a sine wave. We recommend that you purchase a reference CD containing these and other signals commonly used for level calibration. It's very difficult to calibrate any professional audio device using regular music or program material. To use Input Level mode: · Starting from within Program mode, press and hold the Page button for three seconds. [. . . ] Both could yield the same steady state (continuous tone) response but sound completely different to something with a fast transient response such as a snare drum or clapping. By popular demand, one of the Presets is modeled after the ubiquitous black monitor with white cones, but it is a rough approximation. How does the level control on the rear panel differ from the front panel Gain Trim control?The level control on the back attenuates the input signal to the speaker. [. . . ]
