NQ-PA120, NQ-PA240, NQ-PA600 Public Address

Ampliers Installation and Use

The Nyquist Public Address Ampliers are DSPbased integrated mixer and power ampliers de-

signed for paging and public address applications. They enable microphone and line-level source inputs to be integrated into a Nyquist system. The NQ-PA120 and NQ-PA240 public

address ampliers

are each a half-rack

1RU high enclosure.

The NQ-PA-600 public address amplier is a half-rack 2RU high enclosure.

Each enclosure contains a Class D audio power amplier, a universal switched-mode power supply, an RJ45 network jack, a USB port, and pluggable

Phoenix style terminals for Mic/line inputs, and loudspeaker and Line-Out connections.

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 polar- ized 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 electrician for replacement of the obsolete outlet.

Page 6

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 which 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 person-

nel. 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

Page 7

apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

This equipment is not suitable for use

in locations where children

are likely to be present. Equipment is

intended for use

only in a restricted access area.

Installation

To install the Nyquist Public Address Amplier:

1. Ensure the POWER switch is in the off position.

2. Connect the universal mains power line cord into

the amplier.

3. Connect a Cat5 type cable into the amplier’s

Ethernet port and ensure the other end of the cable is correctly connected to your network.

Page 8

4. Connect the loudspeaker wires to the Amplier Output Terminals, which are labeled + and -.

This amplier is congured for single-channel operation for 70V/8Ω applications.

Page 9

Notice

The minimum impedance of this 70V/8Ω High Impedance system should not be less than 8Ω.

The combined total power of each speaker tap must not exceed 80% of the rated amplier power.

Failure to observe minimum speaker

impedance will cause the amplier to self protect until the speaker conguration is

corrected.

5. If using Mic/Line Input, route the input.

This amplier uses a balanced analog audio

input. You can use either XLR or Phoenix (but not both) as the input.

6. Plug the power line cord into the power

source.

7. Toggle the Power switch to the On position.

8. For information about conguring the amplier for the Nyquist system, refer to the Nyquist Pub- lic Address Ampliers Conguration Manual.

Power Ratings

The NQ-PA120 can provide 120 Watts into 70V or

8Ω load congurations.

The NQ-PA240 can provide 240 Watts into 70V or 8Ω load congurations.

The NQ-PA600 can provide 600 Watts into 70Vor 8Ω load congurations.

Viewing and Understanding LEDs

Two LEDs appear on the

front of the amplier. 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.

Page 11

The STATUS LED uses the following indicators to provide information about the appliance:

• Flashing red – No network connection found.

• Solid blue – The amplier is in an uninitialized state and is not associated to a server. (The server may be in a discovery mode.)

• Solid green – The amplier is registered to a Nyquist server and is in normal operation.

• Flashing green – The amplier has an IP address but is not registered with the Nyquist server.

• Solid red – The amplier needs to be rebooted or reset so that the Nyquist application can resume.

• Flashing blue – The amplier is updating.

Clipping, Protection, and Temperature Indicators

In addition to the LEDs that appear on the actual appliance, separate amplier module signal

clipping, protection mode, and temperature status

indicators appear in the Nyquist amplier’s web-

based user interface. For more information about these status indicators, refer to the Nyquist Public

Address Ampliers Conguration Manual.

Using the Reset Button

The Reset button allows you to restart the appliance or to reset the

appliance’s conguration settings to

the factory default settings. For more information
