Compact 4-channel digital amplifier

With the Impulse 4.320 amplifier, breathe new life into your car radio. The amplifier of a car radio (standard equipment or purchased subsequently) very quickly admits its limits in terms of power and dynamism. At high sound levels, it quickly goes into saturation and spoils the musical pleasure. To compensate for this lack and allow your speakers to express themselves fully, the Impulse 4.320 is the ideal solution. It will boost your installation without the need for complicated assembly. Semi “Plug and play”, the Impulse 4.320 is a 4-channel digital micro amp, delivering 4 x 55 Watts. The Impulse 4.320 perfectly complements the Focal Integration speakers.

TECHNOLOGY PLATFORM FROM FD AMPLIFIERS

The technology used for Impulse 4.320 was inspired by the Performance range’s FD amplifiers.

With an efficiency of more than 90%, Class D amplification has numerous advantages: less heat, low power consumption, low distortion at high volumes, compact… With the Impulse 4.320 amplifier, an unbeatable size/power ratio has been achieved. It delivers 4 x 55 or 2 x 160 Watts RMS at 4 Ohms.

Thanks to the adequate power and the fast attack for realistic and more aerated sound, it will completely transform the sound of your front and rear speaker drivers.


VERY EASY TO INSTALL AND PERFECT INTEGRATION

Impulse 4.320 – Cables Measuring only 67/8 x 17/8 x 25/8? (17.65 x 4.6 x 6.7 cm) Impulse 4.320 can easily be concealed within the dashboard or the centre console.

Equipped with high-level (automatic detection feature) and low-level inputs, it is compatible with all head units. Supplied with all fastenings, an adaptor for the head unit’s speaker driver outputs, RCA adaptors for aftermarket head units and power connector, this amp was specially designed to be easy to install. No direct hook up to the vehicle’s battery is required.

An optional ISO connector is available for Plug&Play connectivity via the head unit’s harness.

Note: On certain cars, a harness adapter may be necessary.EXTREMELY VERSATILE

To ensure compatibility with different head units, this amplifier features a 2-channel or 4-channel input selector switch.

Most of all, Impulse 4.320 has been designed to power front and rear speaker drivers. However, it can also be used in a 3-channel or 2-channel mode in order to meet all needs for improving small installations and it can also be used for powering the front speaker drivers and a small subwoofer.

Each pair of channels features an active crossover to adapt the sonic response according to the speaker drivers used. The front channels can be used for wideband speaker drivers or the high-pass filter can be used for frequencies above 75 Hz when only small speaker drivers are used. By avoiding having small speaker drivers reproduce very low frequencies, the sound will have more clarity. The rear channels are equipped with an active crossover (wideband, high-pass or low-pass) and with progressive phase adjustment for powering a small subwoofer or wideband speaker drivers of different sizes.


“Y” Adapter cable – FOCAL IMPULSE 4.320 cable kit for quick connection of Impulse amplifier in vehicles with ISO Standard wiring connectors behind the head unit. Simply unplug the ISO plug and connect this cable kit inline (with the Impulse amp) for an immediate improvement in power and sound quality.

Overall very satisfied.
Color: Walnut
The TV stand is very simple to assemble and most people should be able to complete it in a little while, as several steps may require a second person. The unit itself is very sturdy and a little larger than I expected. The sliding "door" does require a little force to move, but furniture wax should do the trick nicely.

Beautiful quality made tv stand.
Color: Walnut
Beautiful TV stand. Easy to assemble. I took a chance on this stand matching the new end tables I got from a different store and manufacturer. They match perfectly. I couldn't be happier with the color of the wood, the quality construction and minimalist clean look. It looks great in my living room.

Modern and sleek
Item Package Quantity: 1
I haven't assembled this yet but I'm really looking forward to using it as a nightstand - the style looks really sleek and modern and it seems like it'll fit perfectly in a small space. It's worth noting that it's made of particle board rather than solid wood, which is pretty standard at this price point, so just go in with that expectation. The design looks really clean and the storage shelf underneath is a practical bonus. Hoping it holds up well over time but based on first impressions and the overall look, I think it's going to be a really nice and affordable addition to the bedroom!

Decent looking but not very sturdy
Item Package Quantity: 1, Item Package Quantity: 1
This table looks pretty nice once it is fully assembled and I appreciated that all the parts were clearly labeled. There were no missing parts, and in fact there were some extras. That made the instructions easier to follow and helped speed things up. From unpacking everything to finishing assembly it took me around 30 minutes. There are a few quality issues though. The black finish feels very thin and started chipping around the screws while I was tightening them down. It does not seem like it will hold up very well over time if it already shows wear during assembly. The biggest issue is the stability. Even after tightening everything, the table still feels a little shaky. The set screws near the bottom base pieces do not stay tight for very long and kept loosening while I was putting it together. I assembled it by myself and the legs kept shifting and falling over because those connections would not stay secure. This is definitely easier if you have another person helping. The packaging also could have been better. The box had a lot of particle board dust and debris inside, so unpacking everything was a bit messy. The item description says it can hold up to 66 pounds, but after putting it together I personally would not trust it with anywhere near that much weight. I originally planned to use it for a small aquarium that weighs around 20 pounds, and even that made me uncomfortable once I saw how flimsy the table felt assembled. I think it is better suited for lightweight items and I'd only store something like a couple of books or a lightweight lamp or a couple of picture frames. Overall it is not terrible and it does look reasonably attractive, but the build quality does not really match the current fifty dollar price in my opinion. It should be priced lower. It works for light decorative use, but I would not expect anything especially sturdy or long lasting.
