Quattrocanali 1204 offers the traditionally amazing sound quality and reliability of all Powersoft products.
The patented SRM (Smart Rails Management) technology allows to maximize the efficiency of the system and drastically reduce power consumption in any load and usage condition. Quattrocanali features the lowest thermal dissipation in the industry, reducing the need for external cooling devices.
Quattrocanali is designed to operate with lo-Z (from 2 Ω) and 70V/100V distributed lines or any mix of the two.
DSP+D versions of the Quattrocanali grant in-depth control and monitoring via ArmoníaPlus, tailoring the sound and managing the system can be done by a remote, decentralized location.
This Amplifier Platform can also be trusted in mission-critical applications, such as fire alarm systems, thanks to the cleverly engineered power supply that allows reliable operation even when connected to a UPS.
Features
Power supply
- Powersoft legendary universal switch mode power supply up to 400VAC tolerant with Power Factor Correction
- Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
- Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket
Protections
Fully protected circuit design with:
- Ac protection: shut down power supply when AC mains voltage is outside operating range
- Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
- DC protection: protects against infrasonic signal at the outputs
- VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
- Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
- Long term limiter: protects the loudspeaker against steady long term rms (non audio) signals reducing maximum output
- Thermal protection: output stages operating temperature up to 80 °C (176 °F)
- Temperature controlled continous variable speed fan, front to back airflow
- Temperature forecast with LCD traced historical behaviour
General
- Fixed frequency switchmode output stage for high grade sound accuracy
- Compact size - all models only 1 RU for reduced rack cost and space
- Light weight - for easier racking and shipping: 7 kg (15.4 lbs)
- Standard Phoenix connectors: analog audio outputs, aux supply, alarms and GPIO

Worth the price
Scent: Face Wash, Size: 5.1 Fl Oz (Pack of 1)
Although I was hesitant to buy this at first since it’s about twice the price as the facial cleansers I normally use, it’s by far the best face wash I’ve ever used. It exfoliates the skin very well and leaves your face feeling clean after use. Definitely worth the extra few dollars

Greasy, does not blend in well but does not leave white marms
Overall, when researching this product, I saw that it does not leave the white residue on your face like normal sunscreen does, I’m looking for a face moisturizer first with SPF but this one feels more just like an SPF sunscreen. It is pretty greasy shortly and after a few hours of having it on, especially when sweating it makes my face feel really oily, and also it does not blend in very well such as pretty much like I just mentioned you could still feel it on your face a couple hours later but if the no white resident is the most important thing for you, it does not leave that residue. It’s cruelty free and vegan product (no animal products in it or animal testing done) so that’s good but I will most likely not be purchasing this .

So so good!!!
Scent: Face Wash, Size: 5.1 Fl Oz (Pack of 1)
This face wash is a game changer! From texture to smell it is perfect. I ordered this for my husband to replace his usual "routine" of washing his face in the shower with bar soap (gasp!). I not-so-sneakily put this in the shower and at his first sample of it he was hooked. It's the only face wash he's tried and actually likes to use on a daily basis. Also, the price point is great! Definitely recommend for anyone seeking an awesome face wash at a perfect price.

A lot of these poems leave me feeling like an idiot
Format: Paperback
This is the type of book I read at 3 am when I can't sleep. Stevens' poetry just makes me feel so calm, even though the content in his poetry is not in fact anywhere near the realms of calm. Overall, I would say, the content is hard-hitting. I'm not going to pretend I understand all of his ideas and everything he says- I definitely don't. A lot of these poems leave me feeling like an idiot. But when I am able to figure something out, it all starts to click and I am left with a lump in my throat. Although I don't necessarily understand everything when it comes to this collection, I think that it is a good thing. It just shows the high level of his talent manages to knock me off my feet.
Well, anyway, I got my first peak of this collection at uni. I was so intrigued by it that I bought it during winter break. While reading it I found out one of my professors is an editor of the edition that I bought. Rad. But also, the thing is, (and I have thought this many times before,) uni can only teach you so many things. I learned much more about Stevens' poetry by reading it myself than what I learned from uni. Like, without reading basically this whole collection, I would have never learned that Stevens is, for the most part, a Romantic. He's a lot like Wordsworth, I think. He inherits so many of the Romantic feelings, ideas and philosophies but he still manages to stay modern at the same time. I am obsessed with the Romantic poets so in my mind, that's what makes him stand out. I love the fact that he manages to tie modernism and Romanticism together, it is a real treat for me to read. Even though it's not really talked about, I would say my favorite poem of his is "Another Weeping Woman". It is so quick and beautiful and earnest and a good poem to read when you lose one of your loved ones.
Over the past couple of years I have really warmed up to poetry. I'm not a huge American lit person in general but I always tell people that Stevens is one of my favorites, if not my favorite American poet. Everything about his work seems so personal, like when you're reading it, it feels like he is speaking directly to you. It feels so natural but honestly nothing about reading his poetry is easy. It is tough to figure out. But I enjoyed taking the time to sit down and try to hypothesize all that is going on in his works. He is dark, so dark and yet manages to feel so light, so beautiful. He delivers the best of both worlds in my eyes and that's why I will revisit this collection again and again and again. It never stops being so hideous and so beautiful at the same time.
