Frequently Asked Questions - Nyquist NQ-PA120 Bogen
What is the Bogen Nyquist NQ-PA120 used for?
The Bogen Nyquist NQ-PA120 is a commercial network paging amplifier designed for public address systems, background music, paging announcements, and emergency notification in retail, schools, and corporate environments.
What speakers can I connect to the NQ-PA120?
It supports 70V/100V constant voltage speakers as well as low-impedance (4-16 ohms) speaker systems. The amplifier can drive multiple speakers when using a constant voltage distribution network.
Does the NQ-PA120 require a separate power supply or can it use PoE?
The amplifier includes a universal AC power supply for full output. It also supports Power over Ethernet (PoE+) for network connectivity and background power modes, but for 120W audio output, a local AC power source is required.
How do I configure the NQ-PA120 network settings?
The unit has a built-in web-based interface. Connect the amplifier to your network and access it via its IP address using a browser. From there you can set IP addressing, zone assignment, volume, EQ, and scheduling.
Can the amplifier be controlled remotely?
Yes, the NQ-PA120 supports remote control via Bogen's Nyquist paging software, web interface, and GPIO inputs for contact closures. It can integrate with automation systems using TCP/IP protocols.
What maintenance does the NQ-PA120 need?
Regular maintenance is minimal. Keep the unit free from dust, ensure the cooling fan air intake is not blocked, and periodically clean the exterior with a dry, soft cloth. Avoid using liquid cleaners to prevent damage.
Is the NQ-PA120 suitable for 24/7 operation?
Yes, the amplifier is built with industrial-grade components and a speed-controlled fan, making it suitable for continuous commercial use. The fan extends product life by automatically adjusting to the internal temperature.
How do I perform a factory reset?
To reset the NQ-PA120 to factory settings, press and hold the Reset button on the rear panel for 10 seconds until the power LED flashes. This will restore the default IP, username, and password.
What is the difference between 70V and 100V speaker systems?
In constant voltage systems, the amplifier outputs a standard voltage (70V in North America, 100V in Europe). Each speaker has a matching transformer, allowing many speakers to be connected in parallel, regardless of distance, with simple wire runs.
How many speakers can be connected to the NQ-PA120?
The number depends on the speaker power tapping and the total load. For a 120W amplifier, if you use 70V speakers with a 0.5W tap, you can connect up to 240 speakers. Ensure the total speaker wattage does not exceed 120 watts without overloading.
