NQ-A2060, NQ-A2120 Audio Power Amplifiers Installation and Use These networked Audio Power Amplifiers support a full range of commercial paging and public address applications, regardless of the venue size. Both the NQ-A2060 and the NQ-A2120 can operate in 2-channel mono or single channel bridged mode, depending on the application need.
WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. Avertissement: pour réduire le risque d’incendie ou de choc électrique, ne pas exposer cet appareil sous la pluie et l’humidité. The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be placed on apparatus.
- il convient que l'aération ne soit pas gênée par l'obstruction des ouvertures d'aéra No naked flame sources, such as lighted candles, should be placed on the apparatus. - il convient de ne pas placer sur l'appareil de sources de flammes nues, telles que des bougies allumées The use of apparatus in moderate climates. - si l'appareil est destiné à être utilisé sous un climat tempéré.
6. DO NOT install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 7. DO NOT defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade, or the third prong, are provided for your safety.
WARNING: The apparatus shall be connected to a mains socket outlet with a protective earthing connection. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases, shall be placed on the apparatus. Where the mains plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.
Bridged mode is typically used when higher power, single channel operation with a high impedance loudspeaker load is desired. A typical use-case would be for 70V or 25V loudspeaker runs, where the total load is no less than 8Ω. 2 Channel mode is typically used for 8Ω or 4Ω loudspeakers runs. This mode allows the two amplifier channels to operate independently. 5.
If two channel mode is used, then Channel A is connected to the A+ and A- terminals and B channel is connected to the B+ and B- terminals. (See Figure 2.) Figure 2. Two-Channel Wiring Notice The minimum impedance of a Bridged 70V/25V/8Ω High Impedance system should not be less than 8Ω. The minimum impedance of a 2CH 25V/8/4Ω system should not be less than 4Ω per channel. 1200 MacArthur Blvd. Suite 304, Mahwah, NJ 07430 1-800-999-2809 © Copyright 2018, Bogen Communications, Inc.
The combined total power of each speaker tap must not exceed 80% of the rated amplifier power in either Bridged 70V/25V/8Ω mode or 2CH 25V/8/4Ω mode. Failure to observe minimum speaker impedance will cause the amplifier to self protect until the speaker configuration is corrected. 6. If using Line Input, route the input. The amplifier uses a balanced line level (up to 2V RMS) analog audio input. You can use either XLR or Phoenix (but not both) as the input.
Viewing and Understanding LEDs Two LEDs appear on the front of the amplifier. One is labeled POWER and appears as solid red during initial power up, flashes green during a boot sequence, and appears solid green when fully booted. The STATUS LED uses the following indicators to provide information about the appliance: • Flashing red – No network connection found. • Solid blue – The amplifier is in an uninitialized state and is not associated to a server. (The server may be in a discovery mode.
amplifier’s web-based user interface. For more information about these status indicators, refer to the Nyquist NQ-A2060, NQ-A2120 Audio Power Amplifiers Configuration Manual. Using the Reset Button The Reset button allows you to restart the appliance or to reset the appliance’s configuration settings to the factory default settings. For more information about resetting configuration settings, refer to the Nyquist Audio Power Amplifiers Configuration Manual.
required to correct the interference at his own expense. Limited Warranty, Exclusion of Certain Damages The NQ-A2120 and the NQ-2060 are warranted to be free from defects in materials and workmanship for five (5) years from the date of sale to the original purchaser.
Products that are out of warranty will also be repaired by Bogen Factory Service Department -- same address as above or call 201-9348500, at owner’s expense. Returned products which do not qualify for warranty service, may be repaired or replaced at Bogen’s option with a previously repaired or refurbished items. The parts and labor involved in these repairs are warranted for 90 days when repaired by the Bogen Factory Service Department.
