The nXp1.54 Network Power Amplifier from Ashly Audio is the networkable version of the nX amplifier. It comes with Ethernet control, serial data control, aux preamp outputs, instant standby mode, preset recall, fault condition logic outputs, and optional network audio and digital audio capability. All these are controlled using Ashly Audio's Protea software suite. This amplifier is designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces, and convention centers.

The Network Power Amplifier adds 32-bit SHARC DSP processing (with 48 kHz and 96 kHz sampling) as standard equipment for comprehensive audio processing, with built-in signal generator for test tone, and noise-masking. Plus, you get precision load impedance monitoring on each amplifier channel output.

Related Questions and Answers

Q: 1. Does the Marantz stereo power amplifier has a midrange sound control?

A: This power amp does not have tone control. A preamp would be paired with this amp, and provide for tone control.

Q: 2. Does the Marantz power amplifier sounds like an amplifier with an equalizer?

A: The Marantz MM7025 provides power only, and would be paired with a preamplifier, which would have inputs for your components and equalization adjustments. The Marantz AV7706 11.2-Channel Network Preamplifier with HEOS, BH #MAAV7706 is an example of a preamp that would work well with this power amplifier.

Q: 3. If your amplifier is CE certified can I get testimony from you to that effect?

A: You can find Ashly's certifications by following the link below, and clicking on the 'features' tab. https://ashly.com/tra-convection-cooled/

Q: 4. Does the Ashly ne8250PE amp come with all the Euroblock connectors or do they have to be purchased seperately?

A: The Euroblock inputs are embedded into the rear chassis of the component. No Euroblock connectors ae included as separate DIY items for crimping/soldering onto your own wiring.

Q: 5. is the input power for the Rolls RA235 220Volts or 110 Volts or it works on both 110V /220 V?Please adviseBest regards

A: The Rolls RA235 is compatible with 120 VAC 50/60 HZ only.

Q: 6. Can I hook an equalizer to this Marantz stereo power amplifier?

A: Unfortunately newer Amplifiers (and Receiver Amplifiers) no longer offer the ability to connect a separate Equalizer like the older models. The current models no longer provide Input / Output ports for Equalizers.

Q: 7. 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: 8. Can you connect a subwoofer to this amp?

A: No

Q: 9. how do you drive 25v output?

A: Not sure what you are referring to. Please send us your questions via e-mail: AskBH@a href= http://BandH.com target= _blank BandH.com/a

Q: 10. Can this be powered by Ac input 220v?

A: This device 120V AC/60Hz only.

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

anyonymous	19/09/2024
Great addition to my system, goes out to a pair of Klipsch Heresy speakers.... sounds amazing and really pushes my speakers... much better sound than anything Bluetooth speakers can provide... Old school wired sound is still the best for music... 5

I have Bose 901 speakers which require an active equalizer so I need a preamp power amp combo. I have a Marantz 5 channel receiver to drive the center and other channels and this works great with the receiver to drive the 901s as the front speakers. B&H shipped this unit quickly and there were no problems. 5

I bought the MM7025 to power a pair of Acoustic Research 303's that each have a nominal impedance of 6.5 ohms and have a max. power rating of 250W. Originally, I thought I needed 200 wpc to make my speakers come alive but the MM7025 exceeded my expectations. I get great sound stage with amazing imaging and clarity. Previous to owning the MM7025, I had a 7.1 ch. home theater AVR with 100 wpc but decided to return to 2 ch. audio with a separates for greater fidelity. In operating my new system, I had to boost treble to hear the highs so the speakers sound more comparable to today's smaller speakers. Sometimes, I needed to decrease bass to hear dialog better when watching movies. This amp performs well. I'm not sure if the sound improved after some break-in time but it seemed like it did. There were a couple of times in which I thought that the volume increased slightly by itself. These experiences however could be psychological. Overall, I would buy this amp again and I recommend it to anyone who wants the power it provides. 5

I had this with my NR1710 and its Fantastic using it for Bi-amp, I wish they put additional volume control on this unit, 5

Edward	25/07/2024
It’s been working perfectly for the last two years. I do wish you had a little more power 5

Henry	21/06/2024
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

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

Carlos J	19/05/2024
The MM7025 replaced a vintage power amplifier and gave new life to my dedicated stereo system. I have both analogue and digital sources, a PrimaLuna tubed preamplifier and B&W 702 S2 floor standing speakers, and this Marantz has proved to be a fundamental link in this chain. It leans a little to the warm side (which I like) and improved the sound of my speakers, with tight bass, very sweet highs, and transparent voices. At this prices level, I can't imagine anything better. 100% recommended. 5

Rick2024	11/05/2024
I have this AMP paired with a Marantz SR7011. It's a little pricey (at least for me), but you get what you pay for. I could not be happier with it. I am running 11/2, a combination of MartinLogan's and Klipsch 12" subwoofers. 5
