TOA DA250FH Class D Power Amplifier 4 x 250W 100V line 1RU High and 6.8kg weight
TOA DA250FH is a 4-Channel Digital Power Amplifier designed for 100 V line high-impedance distribution and features lightweight, compact, high power output, and high efficiency. It delivers 250 W x 4 channels (19.6 Ohm output) using a switching power supply. Each channel is equipped with an independent power section. It can be electrically isolated from the high-impedance speaker system by attaching the MT-251H Output Transformer (optional). TOA DA250FH can be mounted in an EIA Standard equipment rack (1 unit size).
Extremely high amplification efficiency of 80-90%, resulting in reduction in power consumption by more than 60% compared with Class-AB amplifiers.
The DA-250 Series is 1-unit size and the DA-500 Series is 2-unit size. They can be efficiently mounted on a rack, so they require only a small installation space. Because the amplifiers do not generate much heat, 5 units can be stacked together in a rack.
Stands up to extended hours of operation. The DA amplifier has undergone a large number of rigorous tests to prove its durability. In addition, TOA has been conducting a ?non-stop driving test? of the DA Series.
The DA amplifier has a comprehensive protection circuitry for protection against excessive current flow due to overload, short circuit, unusual DC voltage output, and heat sink temperature rise.
Each of the channels has its own power supply. If the power supply of Channel 1 should fail, this won't affect the operation of Channels 2-4 (Channel 2 in case of DA-250D/DA-250DH). It is also possible to use one of the channels as a spare amplifier.

Perfect shades
Color: Tortoise Frame/Brown Lens
I love these sunglasses! I have a small face, and I find that these fit perfectly! They are stylish, fun and I don't have a problem of them sliding down my nose.

Quality for lower price than brand sunnies
Color: Beige Tortoise Frame / Brown Gradient Lens
High quality for a low price. I'm someone who always loses my sunglasses so I won't allow myself to purchase any name brands. I've had my fair share of cheap sunnies for this reason. These are probably the best "off-brand" I've tried - and I've tried a lot. They are definitely polarized and are lightweight with a good fit - some of the cheaper brands are really tight on the ears and the plastic is clearly cheaply made, making them heavier. They are also a cute style with a variety of colors available. The other thing with cheaper sunglasses is they are usually not that great to peer out of. Some of them I can't wear to drive bc they are too dark, or not dark enough for glares on the road. These are great for driving - the lens coloring is just right to see well and also feel like you're not squinting. I'm buying another pair for when I inevitably lose these!

Polarized sunglasses are just what I needed
Color: Tortoise Frame / Mirror Pink Lens
I really like these sunglasses. They are polarized and work great. They fit well and don't fall off when I bend over, which is important. They are light on my face and don't make marks or pressure on my nose. The color is perfect and they are really cute. They are a great value, well worth it. The cleaning cloth and bag to keep them in are a bonus. Very comfortable!
