Four-Channel Full-Range Amplifier: The JL Audio HD600/4 is a Class D four-channel, full-range amplifier that is rated at 150 Watts RMS x 4-channel in 1.5 to 4-ohm at 20 to 20kHz with a signal-to-noise-ratio of 110 dB and a total harmonic distortion of 0.03% while receiving 11 to14.5 Volts. The amplifier can also be bridged to output 300 Watts
For example, one package may say it uses only 11 watts and replaces a 75-watt light bulb. Understanding the packaging and determining the bulb's actual wattage output is essential. In this case, an 11-watt bulb is safe to use in a light fixture with a maximum socket rating of 60 watts despite the packaging that says it "replaces a 75-watt bulb."With a 600W output rating, it can power or recharge small electronics but isn’t designed for high-draw items over 600 Watts. A small package that delivers a lot of power; A kilowatt is 1,000 watts. Smaller solar and wind installations will be defined in kilowatts. A megawatt (MW) is 1,000,000 watts or 1,000 kilowatts (kW), while a gigawatt (GW) is 1,000 MW or 1,000,000 kW. But to measure how much energy we use we need to look at kilowatt-hours (kWh) and megawatt-hours (MWh). Although a rock concert in an arena could be powered by 15,000 watts (allowing only 6 dB of headroom for peaks,) you'll often see large touring sound companies using 80,000 to 400,000 watts total. That much power is needed to handle 20-to-24 dB peaks without any clipping, and to power extra speakers for even coverage of a large area. t3xq.
