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. The following display is an example of what may be shown: Hold for three seconds · Once this display is showing, reach around to the back of the ProLinear DSP and set the Input Level control to its minimum position. Select a test tone that has a level very close to 0dB on the CD player and send it to the speaker. Slowly increase the Input Level control until the display reads -10dB. · · To exit Input Level mode, hit the Page button again. 21 2 Operations This page intentionally left blank. 22 3 Using the Software The ProLinear DSP Windows application lets you easily control and configure your ProLinear DSP speakers through a standard 9-pin RS-232 serial connection. You can then apply these settings to one of eight available user-defined programs. Overview There are two main levels of control in the PC software: the Channel level and the Program level. At the Channel level you may select which Channel the software is displaying, what Program is on each Channel, and what the Gain Trim setting is for each Channel. Once you have a configuration of EQ curves and Channels you would like to keep, you may save them as a "Workspace" for later recall. At the Program level, you may adjust the equalizer parameters (Frequency, Q, and Gain) and then save the curve to one of the eight User Program locations within the speaker and within the Workspace at the same time. You can also store a name with each EQ curve as well as a set of notes with the User bank you have assembled. Here is an example of the main software screen: Remember, a Channel may consist of one speaker or a group of speakers with the same Channel setting. The Curve Name is only viewable in the PC software. 23 3 Using the Software Navigating the Software The features of the software are accessed in three ways: · The pull-down menu at the top of the main window, which gives access to the housekeeping features common to most Windows applications, such as file saving and opening, plus cut/copy/paste of EQ settings, and pull-down access to most of the features found elsewhere in the main window. Also found here are configuration options and an extensive Help file. The Channel Bar, which has the labels "Control, Channel, Program, and Level" across its top.
