Ampliers Installation and Use

The Nyquist Public Address Ampliers are DSP-

based 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 en-

closure.

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.

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.

1200 MacArthur Blvd. Suite 304,

Mahwah, NJ 07430 • 1-800-999-2809

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.
