The nXp Series NXP4004 4-Channel 400W Power Amplifier with Programmable Outputs & Protea Software Suite from Ashly is a Class-D switching amplifier combined with a switch mode power supply. This amplifier meets the requirements of demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces, and convention centers.

This amplifier features the Protea DSP processing for efficient control. The rear panel has DIP switches for programming each channel output for either High-Z or Low-Z operation. This amplifier can be connected to a network with Ethernet control and features serial data control, aux preamp outputs, instant standby mode, preset recall, fault condition logic outputs, and optional network audio and digital audio capability, all controlled using the included Protea Software Suite.

The amplifier offers 32-bit SHARC DSP processing (with 48 & 96 kHz sampling) for comprehensive audio processing and built-in signal generator for test tone and noise-masking. It also offers swept load impedance monitoring on each amplifier channel output.

Related Questions and Answers

Q: 1. Why is this Marantz amplifier so expensive and it does not even have decent 4ohm performance. A lot of metal though.

A: This amplifier is not a stock item, and it is currently selling for list price. It's not for everybody.

Q: 2. Can I use/import tracks from my I-tunes library?

A: Yes, n-Track Studio 9 allows you to import and export .wav, .mp3, .wma, .mid, .ogg, .flac, .aiff, .cda, .sng, .sgw audio files, so your iTunes tracks must be a compatible format in order to import them to Studio 9.

Q: 3. I do not see a headset jack. Can you monitor the output through a headset?

A: Unfortunately there is no headphone output available on the PVi8500.

Q: 4. This unit says it has 8-channel AES inputs. Does it also have 8-channel AES outputs?

A: AES3 digital audio output is available as a 4- or 8-channel option for the Ashly ne8800A Network Enabled Digital Signal Processor. The AES3 outputs are pass-through only (no DSP).

Q: 5. Does ashly have a wireless accessibility?

A: The Ashly Protea 4.8SP does not have a transmitter or receiver built into it for wireless compatibility.

Q: 6. What is the maximum delay on an output channel? The block diagram shows 21 ms but that seems like a typo.

A: In the manufacturer's specifications for the Ashly Protea 4.8SP - 4 Input, 8 Output Digital Speaker Processor, the user manual lists 1.46ms as the spec for propagation delay and 0 to 682ms as the spec for input and output delay. This information is shown on page 14: https://www.bhphotovideo.com/lit_files/882193.pdf

Q: 7. The manufacturer is not clear on his specs. 300W per channel at 4 or 8 Ohms?

A: The Crown Audio CDi 4|300 4-Channel DriveCore Series Power Amplifier can supply 300W per channel at 4 ohms and 300W per channel at 8 ohms. This is due to an auto-sensing circuit that adjusts the amp's internal wiring, allowing it to supply 300W per channel, whether it is operating at 4 or 8 ohms.

Q: 8. what causes the beeping sound?

A: Without further detail it is hard to say for certain, but the beeping sound on the Ashly Protea 24.24M - Audio Matrix Processor with Tamper-Proof Operation and System Software for Windows is likely an indication of a process in function, an error, or another undetermined indication.

Q: 9. If i buy the software, will i get a key code?, and in case i will change the laptop can i still install this to my upgraded laptop? does it have limits? can i install this to different computers i have like one at home desktop one to my mobile laptop?

A: You will receive a download code. One license which can be activated on any two laptops at any given time. But only one may be used at any given time. In the Box: Serato DJ Pro (Download) Serato Video Expansion Pack for Scratch Live and Serato DJ (Electronic Download) Serato DVS Expansion Pack Serato FX - Chip Pack Serato FX - Back Pack Serato FX - Jet Pack Serato Flip Serato Pitch 'n Time DJ

Q: 10. how many downloads can i do? 5 computers on the ntrax site thanks

A: You can have up to five installs on all your computers.
