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". this product offers the latest advances in Focal amplifiers. 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. [. . . ] A feature common to most areas is the use of virtual buttons with white labels on the left hand side and a small rectangle on the right hand side mimicking a LED. 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 intended to drive a stereo pair of loudspeakers. they are simply referred to as Amplifier L (L for left) and Amplifier R (R for right). - the two other channels are line outputs, i. They are intended to feed the stereo input of an external amplifier. 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. [. . . ] It is easy to do so with Dual Manager, however it can only be done in Administrator mode. First assess the respective distances between the left and right sources and the targeted listening position. If the left-hand source is at the shortest distance, then it is the one to be delayed. Assuming the left source is driven by the left amplifier channel, in the OUTPUT CHANNEL SELECTOR click on the Amplifier L button. [. . . ]
