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.

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.
