MENU DESCRIPTIONThe attenuation value can also be read on the LCD screen. To change the attenuation for agiven channel, select the channel first by pressing the corresponding “select” button. Thechannel name on screen will then be put between bracket (see on the picture above,channel 2 is selected). Then turn the wheel to change the volume setting.You can select multiple channels by pressing several “select” buttons at the same time.When a selected channel reaches the maximum value, it will cease to increase bycontinuing to turn the wheel, but other selected channels may still increase the setting: becareful not to change a gap between two channel settings when selecting multiple channelsat the same time.Please note that all the LEDS for volume indication are white except the last one(corresponding to 0 dB attenuation) which is Blue. That allows to quickly checking that allvolumes are correctly set on a <strong>NXAMP</strong>4x1 powered TDcontroller.Adjusting DelayNB: You can adjust small differences of gain between channels with the gain menu (seefurther). There is basically no difference between volume setting and gain setting for achannel, this distinction is only done by analogy with traditional amplifiers. The CPU willalways take care of gain and volume settings and decide what the best combination isbetween analog or digital gain to optimize dynamic range of the system.The delay of each channel can be adjusted from the Delay menu. Bellow is a picture of thismenu.The delay value can be read on the top of the LCD screen for each channel (unit is meters).To change the delay for a given channel, select the channel first by pressing thecorresponding “select” button. The channel name on screen will then be put betweenbracket (see on the picture above, channel 2 is selected). Then turn the wheel to changethe delay setting (maximum delay is 66.6 meters).You can select multiple channels by pressing several “select” buttons at the same time.When a selected channel reaches the maximum value, it will cease to increase bycontinuing to turn the wheel, but other selected channels may still increase the setting: becareful not to change a gap between two channel settings when selecting multiple channelsat the same time.In some special situation (active setups in same enclosure for example, like PS15 active) itis mandatory to have same delay settings on two or more channels. Then, changing thedelay on one of these channels will automatically adjust the delays on the other channels.PAGE 38 OF 80
