Each clock state generates a high pulse on HO or LO, the isolated gate driver outputs, with a fixed deadtime inserted between pulses. Once power is applied, U1 generates a 50% clock set by R21 and C28. Diode D4 prevents backwards current from flowing into the regulator. Transistor Q2 and ZD2 form a discrete regulator to power the controller IC. Resistor R7 and D1 deliver the initial voltage from primary-high to turn on the controller, U1, living on a daughterboard.

Primary-high is stored on a pair of series 200V electrolytic caps. Leaving off J9 configures BR1 for bridge rectification when the AC mains are 240Vac stuffing J9 makes the bridge act as a voltage doubler when the AC mains are 120Vac, and gives the same approximatel圓40Vdc.

If lack of Bluetooth is a dealbreaker for you, Logitech’s Z407 system includes wireless connection and comes with a subwoofer, though the overall sound can’t beat the ProMedia 2.1.īut if you’re in the market for a 2.1 system for your desk and you don’t need Bluetooth, you’ll be happy with the Klipsch ProMedia 2.1 THX - especially at the price."The AC mains voltage passes through a small line filter and is then rectified to give approximately 340 Vdc for primary-high. If you don’t have space for the subwoofer, Bose Companion 2 Series III have even better mid and treble performance, but nowhere near as much bass as the ProMedia 2.1. And you need to have a way to connect to the speakers via a 3.5 mm cable. The subwoofer, which makes the robust bass possible, could be a problem if you don’t have a lot of space. With excellent all-around sound - and particularly impressive bass - music, movies, podcasts and even video calls sound great. When it comes to computer speakers with a subwoofer, Klipsch ProMedia 2.1 THX are hard to beat. There aren’t any other adjustments you can make to the sound from the speakers. You then tweak the subwoofer level until you achieve the right balance for your room and ears. Klipsch recommends that you set your computer’s system volume to 70% and control the level of sound through the knob on the right satellite. But if your audio source doesn’t have a way to output sound through a 3.5 mm port (or through an adapter to 3.5 mm), the ProMedia 2.1 isn’t for you. There’s another 3.5 mm input on the side. You then connect the wired 3.5 mm input cable to your computer’s headphone output.
While not large by subwoofer standards, it still takes up space that you may not have in your home office. The hardest part of set up for the ProMedia 2.1 will probably be finding a space for the subwoofer. Impressively, they maintained that volume without distorting - something few speakers can manage. At max volume, we measured about 95 decibels. The subwoofer also gave significant resonance to podcasts and video conference calls, making the talking heads easy to understand.Īnd, wow, can these things get loud. When the Harkonnens attack the Atreides in Dune, the explosions had impressive oomph while the ominous music filled the room, showing off the wide sound the system can produce. Movies and games benefit from the 2.1 system, too. The picked guitars on Fleetwood Mac’s “Never Going Back Again” sounded warm and realistic, as did Lindsey Buckingham’s voice. The quick, throbbing bass pushed the rhythm on The War on Drugs’ “Victim” while the distorted guitars were easy to hear above the mix. The slow, deep beat on Billie Eilish’s “Therefore I Am” sounded rich from the ProMedia’s subwoofer, while her voice was clear coming from the satellites.
