BOGEN NQ-GA40P3 Integrated Power Amplifier
The NQ-GA40P3 Integrated Power Amplifier is a high-quality audio amplifier designed for professional use. It provides powerful and clear sound output, making it ideal for various applications such as sound reinforcement, public address systems, and background music systems.
The NQ-GA40P3 is a 40W plenum-rated Class D integrated power amplifier. Designed to operate over a 10/100 Ethernet network, the NQ-GA40P3 is IEEE 802.3bt–compliant and can be powered using Power over Ethernet (PoE++). The NQ-GA40P3 can direct drive a single 8Ω load and has a bal-anced line output to drive auxiliary power amplifiers, as well as a balanced line input for auxiliary line-level analog input.

- The wall mounting height of the NQ-GA40P3 should be equal to or less than two meters. The mounting process should be conducted by trained professionals with sufficient knowledge and tools to reliably fit the wall-mount fasteners.
Installation
To install the NQ-GA40P3 amplifier:
- Attach the desired analog speaker to the NQ-GA40P3 using the pluggable connectors provided, where the + and − terminals connect to the +/− speaker wires (see “Figure 1” on page 2).
- If desired, attach an auxiliary amplifier to the NQ-GA40P3 using pins 1 and 2 of the pluggable balanced LINE OUT connector, taking note of the marked polarity (+/−). The G shield terminal can be used if necessary.
- If desired, line level output from a preamplifier device can be connected to the NQ-GA40P3 using pins 1 and 2 of the pluggable balanced line connec-tor, taking note of the marked polarity (+/−). The G shield terminal can be used, if necessary.
- Connect a Cat5-type cable into the module’s Ethernet port and ensure the other end of the cable is correctly connected to a PoE switch port on your network.
Viewing and Understanding LEDs
Two LEDs appear on the front of the amplifier chassis. 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
module:
- 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.)
- Solid green: The amplifier is registered to a Nyquist server and is in normal operation.
- Flashing green: The amplifier has an IP address but is not registered with the Nyquist server.
- Solid red: The amplifier needs to be rebooted or reset so that the Nyquist application can resume.
- Flashing blue: The amplifier is updating.
Using the Reset Button
The Reset button allows you to restart the amplifier or to reset the
amplifier’s configuration settings to the factory default settings.
For more information about resetting configuration settings, refer to the
Nyquist NQ-GA40P3 Config-uration Guide.
Temperature Indicator
In addition to the LEDs that appear on the actual appliance, a separate temperature status indicator appears on the module’s web-based user interface. For more information, refer to the Nyquist NQ-GA40P3 Configuration Guide.
Accessories
The PI5660W PoE++ injector can be purchased from Bogen in lieu of using a PoE++–compatible network switch. Visit www.bogen.com for more information.
