Easy to customize to suit your needs, the two-channel design gives you a multitude of options for setting up your sound system. From adding a woofer, tweeters, or other extra speakers to one channel to creating two distinct sounds for two different rooms, the possibilities are endless.

Bold Sound and Peace of Mind

Although it's designed to offer exceptional audio quality, this stereo amplifier also features a variety of safeguards to protect your devices from damage and continue to offer high quality sound without worry. The Quad Balanced design acts as a regulator between the signal from input to output, enhancing the signal as it travels to remove distortion, muffling and other hindrances to give you a crisp, clear sound on the other end of the connection. The depth and clarity is obvious at any volume. The Power Guard circuitry prevents clipping and further distortion that comes from when the volume is too loud, so feel free to turn the volume all the way up without damaging your speakers. 

The Autoformer allows you to use virtually any speakers with an impedance level of 2, 4, or 8 Ohms as it balances the signal to ensure your speakers are not overloaded with more power than they can handle, resulting in a clear, balanced sound that allows the speakers to operate at their optimal level. This feature makes it easy to customize your individual channels with speakers of different impedance levels, allowing you to add a speaker setup to another room through the audio amplifier without worrying about compromising the sound quality.
