NQ-GA400P 2-Channel AoIP Gateway
Installation and Use Guide
The NQ-GA400P is a 2-channel audio over IP (AoIP) encoder/decoder (i.e., gate-
way) incorporating two balanced line-level inputs and two balanced line-level
outputs, along with two Form-C SPDT-type 2-amp dry contact relays. Designed to
operate over a 10/100 Ethernet network, the NQ-GA400P AoIP Gateway is IEEE
802.3af–compliant and can be powered using Power over Ethernet (PoE). The
NQ-GA400P AoIP Gateway can provide two balanced line-level analog audio out-
puts to auxiliary power ampliers and can accept two balanced line-level analog
inputs from auxiliary preamplier outputs.

Important Safety Information
WARNING: To reduce the risk of re or electric shock, do not expose this apparatus to rain or moisture.
Always comply with the following basic safety precautions when installing and using the unit:
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Clean only with dry cloth.
6. DO NOT install near any heat sources such as radiators,
heat registers, stoves, or other apparatus (including ampli-
ers) 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. If the provided plug does not t into your outlet, consult an electri-
cian for replacement of the obsolete outlet.
8. Protect the power cord from being walked on and/or pinched, particularly at plugs, convenience receptacles,
and the point where they exit from the apparatus.
9. Only use attachments/accessories that are specied by the manufacturer.
10. Unplug this apparatus during lightning storms or when unused for long periods of time.
11. Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in
any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
WARNING:
The apparatus shall be connected to a mains socket outlet with a protective
earthing connection.
To reduce the risk of re 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
lled with liquids, such as vases, shall be placed on the apparatus.
Where the mains plug or an appliance coupler is used as the disconnect de-
vice, the disconnect device shall remain readily operable.

NQ-GA400P
Installation
To install the NQ-GA400P AoIP Gateway:
1. If desired, attach an auxiliary preamplier to the NQ-GA400P AoIP Gateway using pins 1 and 2 of the pluggable
balanced LINE INPUT connector, taking note of the marked polarity (+/−). The G shield terminal can be used, if
necessary.
2. If desired, attach auxiliary amplifers to the NQ-GA400P AoIP Gateway using pins 1 and 2 of the pluggable bal-
anced LINE OUTPUT 1 or 2 connectors, taking note of the marked polarity (+/−). The G shield terminal can be
used, if necessary.
3. 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.
4. To connect a device to the NQ-GA400P AoIP Gateway Relay 1 or Relay 2 Form-C dry contact 2A relays, do one of
the following:
a. If the device is congured as normally open, connect to the device using the NO and COM terminals.
b. If the device is congured as normally closed, connect to the device using the NC and COM terminals.
5. If using a 48-V power supply, connect the PS4815W 48-VDC power supply to the module.
Viewing and Understanding LEDs
Two LEDs appear on the front of the amplier chassis. One is labeled POWER and appears
as solid red during initial power up, ashes 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 amplifer is in an uninitialized state and is not associated to a server. (The server may be in a
discovery mode.)
• Solid green: The amplifer is registered to a Nyquist server and is in normal operation.
• Flashing green: The amplifer has an IP address but is not registered with the Nyquist server.
• Solid red: The amplifer needs to be rebooted or reset so that the Nyquist application can resume.
