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. Can this be used just as a center speaker?

A: The Bowers & Wilkins Panorama 3 400W 3.1.2-Channel Soundbar cannot be used as only a center-channel speaker, as it is made to take full audio from the audio output of the TV.

Q: 2. how to bridge 4 speakers at 8 ohms?

A: I'm afraid I had to call the manufacturer in Canada - Alas now days weno longer have the luxury of manuals inside the box with the amp .I also have 4 speakers bridged at 8ohms but cannot remember theconfiguration with the connecting blocks.Once you get this set up you will be well pleased - This Is A terrific power amp - 10 stars PC LA

Q: 3. How to work the effects?

A: The available effects are dialed in via labeled EFX orange-colored knobs located on the front panel under the red MON knobs. Please follow the link provided below for the instruction manual and full operating details:http://bit.ly/1K9VVT9

Q: 4. Is this amplifier CE certified?

A: The Ashly TRA-4150 is Not only CE certified but Safety/Compliance: TUV, FCC, and RoHS.

Q: 5. Is this rack mountable?

A: The AudioSource AD1002 does not offer any rack mounting hardware, however can be rack mounted using a universal rack shelf such as the Raxxess UNS-1 1U shelf. https://bhpho.to/2hfRR7V

Q: 6. Can you use both the front and rear out puts at the same time?

A: Yes, you can use both sets of outputs from the Peavey PVi 8500 Mixer/Amplifier at the same time, as long as they are used for the correct application. The main and monitor outputs on the front panel are used for connection to external power amplifiers or powered speakers, so these outputs bypass the mixer's built-in power amp section. The main and monitor outputs on the back panel are amplified outputs that are used to connect passive speakers.

Q: 7. Can you supply this with power input of 240VAC 50Hz?

A: At this time we only carry the 120v version. You could use a step down transformer with it, such as BH #SEST1500UD.

Q: 8. what kind of speakers to use with these?

A: This amplifier is designed for commercial installation systems that offer 70 or 100 volt taps.

Q: 9. Will this amp work with Bose Virtually Invisible 191 Speakers? Some list this speaker at 6 ohm's. The spec for this amp list 4 or 8 ohm's not 6.

A: Yes, this would be compatible. Bose lists the specs of the Virtually Invisible 191 speakers as 100w @ 8 ohms, but this amplifier would be compatible with speaker that are 4 - 8 ohms.

Q: 10. How do you bridge the inputs so all 4 play the same sound ?

A: Bridge mode can be activated via a selector button on the back panel of the unit.

[5 to 1000 ms/dB] In today’s immersive sound world i.e. Atmos, DTS:X and Auro-3D, the MM8077 is a perfect product for your amplifier needs. I’m very happy with this product. 5

Vette	18/09/2024
[21 dBu] Excellent build and quality. As expected from a Marantz product. 5

Henry	12/09/2024
[32.5 lb] Great sound and quick response. Its a beautiful match to its sister pre-amps (mine is the AV7702MKII). I mostly listen to stereo music, but with the 7 channel amp, it can be excellent home theater. 5

Jay G	26/08/2024
[-20 to 20 dBu] Great clean power reliable performance. Using with Marantz 8055 5

Duke	25/08/2024
[0 to 22 dB] Great unit. I’m very happy with it. I’m running energy connoisseur speakers 5.1 system. Should I get the MM7055? 5

Philip B	22/08/2024
[32.5 lb] Worked great so far. Sound is more analog than expected 5

kanu42	14/08/2024
[32.5 lb] Great amplifier for both music and movies. Sound is clean with great midrange. 5

Chris	26/07/2024
[1.2:1 to 10:1] I read a long time about various multi channel amps before purchasing the Marantz 8077 and matching preamp. I'm beyond pleased with the clean, crisp power coupled up with my SVS Ultra speaker system!! Very satisfied especial in the price! 5

Martin A	26/07/2024
[5 to 1000 ms/dB] Best purchase ever must have for music quality enthusiast. Having a power amp allowed me to also add in professional equalizer to my SR 5011 receiver. Provided power to drive the surround speakers to turn up the movies and music experience to another level which was unachievable with the SR 5011 receiver alone 5

Tumi	29/05/2024
[0 to 6 seconds] Paired with the Marantz AV7705, this amplifier performs admirably. I am a fan of the Marantz sound and this pair does not disappoint. 5
