S.M.S.L SA-98E Speaker Amplifier (2 x 160W stereo). The SMSL SA-98E is engineered around the STMicroelectronics TDA7498E amp chip and is built with quality electronic components from Panasonic, ALPS, WIMA, and Siemens. This amplifier, though small in size, will produce a whopping 160 watts per channel.Key FeaturesUltra-efficient operation for huge wattage outputBuilt with quality electronic components from around the worldSimple operation with a single analog input and smoothly response volume controlIncludes a 36 VDC, 5000 mA power supply for peak performance OverviewIf you need a ton of power in a small space, consider the SMSL SA-98E to drive you speakers. This amp produces 160 watts per channel into a 4 ohm load allowing you to drive demanding speakers without necessitating the space of a large receiver and a super short-circuit and over-temperature output overload protection ensures a long lifespan.Quality craftsmanship is apparent when looking at the components list. Centered around the 85% efficient STMicroelectronics TDA7498E amp chip, the amp is also made up with parts from ALPS, Panasonic, and Siemens.ERO film capacitors have good performances in full-frequency clarity, sound field depth layering, sound texture, intermediate frequency information and the details.Panasonic capacitors have characteristics of low leakage current, low internal resistance, high ripple current, excellent properties, warm sound, intermediate frequency thick and natural, high frequency soft and delicate.ALPS potentiometers are low coloration, low noise, high balance and durable. Operation is kept extremely simple with a single volume knob of the front panel and a single set of stereo RCA jacks for source input. Use this amp with any CD player, portable audio device, or desktop DAC to get powerful, full range sound.Technical SpecificationsAmplifier chipTDA7498EPower output2 x 160W max @ 4 ohm (10% THD)Total Harmonic Distortion @ 1W0.02%Minimum load4 ohmPower supply voltage36V 4AEfficiency85%Frequency response20-20,000HzDimensions168 x 98 x 36mm (including protruding parts)
