We congratulate you for researching this really HI-END amplifier.
The amplifier you have reviewing is a realization conceived by those who love music.

What is the "Duo" amplifier?

"Duo" is the natural evolution of our top of the range "Quattro" but in 2 channel edition.

It was created to provide similar performance at a more accessible price, while remaining faithful to the philosophy of achieving maximum sound quality.

It is the result of over 1 year of research and development to build a car amplifier with exciting performance.

Also for "Duo" the collaboration with Roberto Tognon was decisive.

His experience and knowledge of music do contributed to the creation and development of this project.
The "Duo" adopts innovative circuit solutions with top quality components specific for audio use and will allow you to enjoy your favorite music without losing any detail or nuance.

The excellent measurements and the very high reliability in very compact dimensions make the "Duo" the new reference for car audio 2 channel amplifiers in its price range.

IMPORTANT NOTES:
- Please do use at least 12mmq (6 AWG) power cable for the B+ and GND.
- Near the positive battery pole, within 30-40cm, it is necessary to mount a fuse, better waterproof if the battery is housed in the engine compartment.
- The ground connection is normally done by connecting the amplifier's "GND" terminal to the car chassis, when you do this, make sure you find a safe and reliable grounding point, if necessary, remove impurities, paint residues etc. to ensure the better contact.
- Install the amplifier away from temperature-sensitive components.
- keep at least 5 cm of air above the amplifier.

Proper installation guarantees better performance, follow these notes for installation.

- Use only shielded cables to connect the audio signal between the car radio and the amplifier, it is not necessary to use very expensive cables, but do NOT use bad cables!

- The use of good quality RCA connectors guarantees a good contact, lasting over time and reliable even after several operations of insertion.

- Shielded cables must be kept at a minimum distance of 10cm c.a. from any generators of car noise, such as power units, pumps, cables, etc.

– For power connections use only good cables, of suitable sections and protected in the engine compartment.

The cables for car-audio applications are very flexible and therefore easy to install.
- Carefully take care of the laying of the cables and operate in order to follow different routes to signal cables from power cables.

- It is a good idea that the GND ground of the amplifiers is connected to the same point, together with the audio source's same ground.

– Fix the amplifier securely, to avoid its movement and then the cables jostling.
– The top side of amplifier has to have free air around, at least 10cm.

– A well-designed and equipped system may involve the collection of various devices, if this happens, ensure adequate ventilation of the place where the amplifiers are installed
perhaps with the aid of an additional forced air flow by a fan inside the various compartments.

This amplifier is designed to work only at 12V DC from the car battery, do not attempt to power it with AC or different voltages!
Install the device in a solid way that does not affect driver's guidance
Do not place the device in very hot places (such as the engine compartment).
Make sure that the installation location is not subjected to high humidity and / or splashes of water.
Perform solid and safe connections, using only cables of adequate section and type.
It is absolutely essential to install a fuse of adequate value near of the battery.
In the installation / uninstallation and maintenance operations it is absolutely necessary to remove the fuse located near the battery.

If the device is subjected to severe shocks that could visibly damage the chassis, let it be viewed by the service center or by a professional installer.
Keep the device clean and do not obstruct normal chassis ventilation, do not use aggressive detergents for cleaning.

The maintenance's allowed to the user are set sensitivity, display setting and the replacement of the fuse with identical characteristics, (to be performed as described in the "Diagnostics" paragraph).

Best organizer with a water spout to keep them counter dry!
Color: Black - 9.25″, Color: Black - 9.25″
I am thoroughly impressed with this product. I tried a product that goes over the middle of the sink and it blocked everything off and would always fall off in a funny ways. I had no room for my pots and pans and started getting irritated with it. This is up and out of the way has a little spicket to drain off the water and as you can see I got all of my sponge and soaps in the same spot which is wonderful cleaned off my counter beautifully. I chose the color black to blend in with my black countertop and also to look nice and clean on the counter. One of the best organizers I have ever found for a countertop. It's sturdy metal so far seems rust resistant, but I haven't had it long enough to know for sure. Mobilize easily to clean. Fabulous little sink caddy. I highly recommend to those of you that like to be organized and keep your counter nice and dry, and still arrange things so that it can be out of the way.

No Rust, No Fuss, A simple but great Sink Item
Color: Black - 9.25″
For years I just had my sponges just laying on or around the sink but this year I decided I needed something to hold the soups and cleaning detergent. Along with not being too pricy and that is how I stumbled upon this sink caddy it has worked amazingly. It holds the detergent, sponge, and tube brushes with no problem and any water is drained out from the little spout underneath it. You can adjust the dividers so you can have how you want things separeted from each other and with the bottom being plastic you don't have to worry about getting any rust there. If you need something to make more space around your sink this item will help you.

Functional neat and worth it!
Color: Navy Blue - 9.25″
This caddy has been even more useful than I expected. It instantly made my kitchen look cleaner and more organized compared to having wet sponges sitting on the sink. My counters look much tidier now, and the sponges dry out much better. It may seem like a small addition, but it really makes a big difference.

Makes the Sink Area All the More Organized
Color: Silver With Towel Rack - 9.25″, Color: Silver With Towel Rack - 9.25″
At first glance I'm sure most people might think this kitchen accessory is kind of silly; a caddy for your sponge and dish soap? But honestly, it makes the kitchen area look at the more organized and keeps things in place. I sprung for the model with the towel holder because I always feel weird about bacteria sitting in the wet microfiber cloth that I use for cleaning the kitchen countertop and my dining table. The little dowel allows it to dry very quickly. The holder can be configured in a few different ways to accommodate your cleaning items. I like that it's wide enough to comfortably hold the large bottle of dishwashing soap I buy and it's the perfect width for Sponge Mommy/Daddy sponges. I've had it less than a week and haven't had to wash it yet, but it seems like it will hold up well in the dishwasher and won't rust. Since I don't have any sponges on a handle, I may use the removable compartment for those (that you can see on the left in my photo) for other kitchen tools.
