User manual FOCAL DUAL MANAGER

[. . . ] We thank you for choosing Focal amplifiers for your Car Audio system and for sharing our philosophy: "the Spirit of Sound". In order to obtain the best results, we highly recommend you have your new amplifier installed by your local Focal distributor. To maximise the use all the functionalities of your amplifier and to fully enjoy its performance levels, we recommend that you read the entire instructions in this booklet, as well as the Focal Dual Monitor software manual. Introduction The Dual Manager program has been designed to give you the entire control over a car audio system comprising one Focal Dual Monitor amplifier, operating together with its remote controller. [. . . ] This virtual LED will appear in green when the function corresponding to the label is selected or enabled, or in light grey otherwise. Output channel selector The Dual Monitor amplifier includes 4 output channels: - two of those channels are the "normal" amplifier power outputs, i. they are simply referred to as Amplifier L (L for left) and Amplifier R (R for right). They are named Line Out L and Line Out R, for the left and right channel respectively. Selecting one or a pair of output channels is done by clicking on one of the 6 buttons laid out in the Output channel selector box. Once a particular output channel (or stereo pair of channels) is selected, the entire screen and all displayed parameters will refer to this channel or pair of channels. future edition of parameters will also apply to the same channel(s) only. In Administrator mode, each of the 4 output channels can be individually selected (4 rightmost buttons). in Restricted user mode , output channels can only be selected as stereo pairs (two leftmost buttons). Note: the 30 band Equalizer operates before the crossover section (which then divides the signal path towards the Amplifier or the Line outputs): it can be seen as located on the inputs rather than the outputs. Crossover The CROSSOVER section is located in a box underneath the OUTPUT CHANNEL SELECTOR, on the left side of the screen. A virtual On/Off button is located in the upper left side of the box, enabling or bypassing the whole crossover section. The following settings are available: · Crossover type This parameter defines the crossover operation mode, out of four possible ones: Band-Pass (both high pass and low pass are activated), Low-Pass (high-pass is disabled), High-Pass (low pass disabled), and Off (both high pass and low pass are defeated). To edit this parameter, just click on the combo box where it is displayed. Filter type (Administrator mode only) This combo box lets you choose between Butterworth and Linkwitz-Riley. Remember that for the former type, frequencies are defined as -3dB points whereas for Linkwitz-Riley of even order they are -6dB points. Slope The selectivity of each filter (low pass and hi pass) can be set to 4 possible slopes, displayed in dB per octave 6, 12, 18, 24. Frequency The frequency of each filter can be set individually using the corresponding combo box. to edit one frequency , click on the arrowed button on the right and a drop-down list of values will appear. You can use the scroll bar to navigate through the list, point to the chosen value with the mouse and click to confirm. Alternatively you can type the desired value directly in the frequency box (followed by [Enter]). The Q-bass is actually a parametric equalizer (PEQ), which possible adjustments are: · Level Define the level of boost or cut at the center frequency of the Q-bass. [. . . ] To zoom around one particular area of the graph, locate the mouse cursor on the upper left corner of this area, then do a left click and drag the cursor down to the lower right corner of the area, then release the click button. the graph area will be re-displayed so to be entirely occupied by the selected portion of the curve. To zoom out back to the default scale, position the mouse cursor to one point inside the graph, left click and drag the cursor upwards and to the left, then release the click button. Special edition keys When a parameter is edited by selection among a drop-down list of values, some particular keys can be used to navigate through the list: - [È] and [Í] keys: move one value up or down in the list - [PageUp] and [PageDown]: move one page up or down in the list - [Home] and [End]: go to the first or last value in the list - [Á] and [Ë]: (time delay only) increment or decrement 5.
