Page 5: Introduction
Introduction The NEAR ® 7XL Power Amplifier is a highly flexible and intelligent digital audio, 2-channel, Class-D power amplifier, delivering up to 700W per channel @ 4/8/16Ω and 70V/100V Constant Voltage Lines, in Direct Drive, without using internal output transformers. A Line Output is also available with independent DSP parameters for driving additional line-level devices. -
Page 6: Panel Descriptions
Panel Descriptions Front Panel 1. “Stand By” Button - Puts the amplifier into low-power consumption, or “Stand By” mode. The but- ton will appear as back-lit Red when in “Stand By” mode. 2. Signal Clip Indicators - Summed LED read out of corresponding Input and Output. Green - Signal is present. -
Page 7: Installation
Installation Ventilation The 7XL Power Amplifier was designed to either be placed on a table or rack-mounted. For rack- mounted applications, the amplifier(s) can be stacked directly one on top of the other for maximum use of the rack space available without any extra, empty rack spaces between them. -
Page 8: Connections
Connections Speakers For 70/100V and 4/8/16-ohm Speakers The 7XL was designed to drive 70/100V constant voltage and 4/8/16-ohm type low-impedance speaker loads. The use of lower impedance speakers may cause the amplifier to engage its protection circuits and shut down or limit amplifier function. -
Page 9: Operation
Operation Power Switch The Power Switch is located on the right rear of the 7XL unit. Press the “I” side of the switch to turn the unit ON. The amplifier will begin its power-up process once turned on. Front LED Indicators The front of the 7XL contains 3 LED indicators, one per output channel: CLIP –... -
Page 10: Software Controls
A MS-Windows (PC) interface (GUI) application is available for setting-up the param- eters of all the available processes of the NEAR 7XL. This can be downloaded from the NEAR website at: www.nearspeakers.com/7XL Once downloaded, proceed to install by executing the set-up file. -
Page 11: Software Control
Software Control After the connection takes place, you will see the IP List window appear. Double-click on IP Address/Device shown in the IP List. If in Standby Mode, the amplifier will show the following screen: To Exit Standby Mode, press the red On/Off Button located in the upper right corner of the window. - Page 12 Software Control Home/Level window. From the Home/Level window the following Tool Bar actions can be taken: Load: clicking on this icon, a window will open allowing to load a preset previously stored within the PC. Save: clicking on this icon, a window will open allowing storage of the current preset within the PC.
- Page 13 Software Control From the Home/Level window the following Configuration Settings are available: Input Source: Either of the following three options can be selected as the active input for the InA and InB input channel sources: Balanced Input: Input is coming from rear panel balanced XLR connectors. Unbalanced Input: Input is coming from rear panel unbalanced RCA connectors.
- Page 14 Software Control DELAY Editing Page window. Delay: The delay can be expressed in Time or Distance: Milliseconds [ms] or Meters [m]. Delay[ms/m]: Desired Delay to the Input and Output paths can be entered manually, or the delay can be adjusted via arrow buttons (Max Delay per cahnnel is 961ms or 326m): Adj: the delay can be adjusted by minimum steps of 1 ms or 0.34 meters Fine: the delay can be adjusted by minimum steps of 22us or 6.8mm Polarity: this allows the polarity of each input/output to be inverted by 180˚.
- Page 15 Software Control InA/InB Editing window. Noise Gate: Allows Noise Gate, when necessary, to improve the noise floor of an input source. Thr – Sets threshold where Noise Gate starts to mute input signal; range from -60 to -20 dBV. Release – Sets the time used by the Noise Gate to unmute the signal once the Threshold is exceeded; range is from 10ms up to 1sec.
- Page 16 Software Control InA/InB Editing window: Cursor (detail). Cursor: The InA/InB Editing window also displays a graphic of the active EQ filters. By turn- ing ON the “Cursor” feature, the Center Frequency and Gain can be adjusted by “dragging” the EQ cursor point with the mouse pointer. View All window.
