Beef up your sound system with the sleek and powerful Topping TP22 TK2050 Class T Amplifier. This amplifier is modeled using Tripath TK2050 IC technology. It issues 30 watts per channel into four ohm loads to ensure remarkable power efficiency and signal chain fidelity. The system offers built-in loudspeaker protection and dual stereo RCA inputs for connecting to any two sources. The audiophile-grade TP22 amplifier will solve all your sound enhancement needs. For example, it can power near-field monitors, bookshelf speakers, and even small-scale tower speakers. Users do not have to worry about its longevity because it features reliable, state-of-the-art components. These include an ALPS potentiometer, matched KOA resistors, OMRON low-loss relays, Panasonic capacitors, and Toko inductors. All of these are mounted onto a 24-karat gold-plated circuit board and protected by a sturdy, extruded aluminum chassis casing. The face of the unit is sleek and simple. It features only a volume knob and two switches. One switch turns the unit on and off while the other goes back and forth between the two input sources. The rear of the unit is just as simple. There are two left and right inputs and two positive and negative outputs. Plug your audio source into one of the inputs and connect one of the outputs to your stereo speaker system. The Topping Tripath TP22 T-Amp 30W Class T digital amplifier is packed complete with HiFi electronic components. These include a TOKO digital amp Inductance DASM1620, an ALPS Potentiometer, and matched KOA Resistance. They also include a Nichicon FW Capacitance, an EPCOS Capacitance, and an OMRON Relay. The unit's suitable speaker impedance is from 4 to 8 ohms and its input sensitivity is 330mVrms. Its output resistance is 0.28 ohms. Its maximum output power is 25.7 watts at 4 ohms and 12.8 watts at 8 ohms. Its minimum THD+N is 0.006 percent and the THD+N at 1 kHz is 0.013 percent. Its frequency response is 20 Hz to 20 kHz +/- 1.8 dB. It offers less than 2mV of noise for ultra-quiet operation as well as 29 dB of gain at 1 kHz. Hook the unit up to your passive preamps, graphic EQ, or any other vintage audio gear. You'll still enjoy the unit's 90% power efficiency, producing 90% audio and only 10% heat. Enjoy crystal clear highs and smooth, solid bass lows. This Topping T-Amp power amplifier includes two left and right gold-plated RCA analog input ports.
