NXAMP4x1 & NXAMP4x4 User Manual - Nexo

MENU DESCRIPTIONgives the attenuation value for each LED.The 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 NXAMP powered TDcontroller.Adjusting DelayNB: You can adjust large differences of gain between channels with the volume menu.There is no difference between gain and volume setting; this distinction is only done byanalogy with traditional amplifiers. The CPU will always check gain, volume, patch andheadroom settings and decide what the best combination is between analog or digital gainto optimize the 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).PAGE 40 OF 103
