SmartAmp 20 is an amplifier with built in Digital Signal Processing (DSP) specifically tailored to optimise the performance of the Optimal Audio loudspeaker range.

This four-channel power amplifier can drive either conventional low impedance or 70V – 100V loudspeaker loads. Internal DSP presets of Optimal Audio loudspeakers are selected by switches to the rear of the amplifier, which enable the appropriate EQ and overload protection settings.

The space efficient half-width, 1U, 19” rack housing enables two units to be mounted side by side with a SmartAmp 10 or another SmartAmp 20, allowing up to 8 channels in a 1U space.

The SmartAmp 20 is capable of a maximum of 250W output shared between each pair of channels. This enables SmartAmp 20 to flexibly deliver power required for each channel within a pair, depending on the system requirement. For example, if one channel was to only be using 20W of power for some Up speakers, the other channel in the pair could deliver the remaining 230W of power for a more demanding application.

Power factor Correction power supply technology enables universal AC mains operation, eliminating the need for local market specific power regulation and potential reliability issues. The power supply delivers consistent, regulated power worldwide with ultra low standby power consumption for EuP2103 and energy star compliance.

Works great. Wish pieces came apart.
Size: 15-Foot
My only suggestion is that the pieces are made more easily to take apart so that you can buy two and combine them for a longer ramp. But they don’t advertise that capability so i cant dock a star for it. Otherwise work great.

Nice and easy does it
Size: 15-Foot
Perfect for when you're camping with full hookups. This keeps your sewer hose off the ground and up just enough to drain while camping. It spreads easy and evenly. I like not having to put blocks, metal hooks, or something else to set the hose on. This is quick and easy. It's very durable plastic and if needed easy to rinse off. It comes with an orange piece that hooks onto it to keep it together to make it great for storing. We have a gray tank in front and gray and black in back. We use two sewer hoses when camping with full hookup. I bought two of these so one is under each sewer hose. The look of these is just "neater" versus tacky like my uneven blocks were. They are very stable once put in place whether on concrete or gravel campsite.

Perfect, Safe Hose for My Rain Barrel Setup
Style: 1/2-Inch ID, Size: 4 Feet
This Camco TastePURE 4-foot water hose has been perfect for my rain barrel setup. The length is exactly what I needed for a clean, simple connection without excess hose to deal with. I really appreciate that it’s drinking-water safe with no lead, BPA, or phthalates. Even though I’m using it with a rain barrel, it’s reassuring to know it’s made from safe materials. The reinforced design feels sturdy and durable, not flimsy like cheaper hoses. The 1/2” inside diameter provides solid water flow, and it’s made in the USA, which is a nice bonus. Great quality, reliable, and exactly what I was looking for. Easy 5 stars.
