The Russound® AVA-Series Mini-AVR Audio Receivers is a game-changer in the audio industry. They are specialized TV amplifiers that can be used seamlessly with any modern TV so you can easily add in-ceiling, in-wall, soundbar, bookshelf, or other speakers. The AVA3.1 has a 3.1 speaker/subwoofer output to match existing soundbars or speaker setups. The built-in HDMI® ARC input with CEC control means it works with the same remote as the native TV or cable box/satellite remote already in use. If desired, the multiple inputs can be used to convert the AVA-Series into a mini-receiver supporting up to 4 total inputs (HDMI®, Digital Optical, Line-Level Stereo, and Bluetooth®) and it includes an external IR sensor and full-featured remote. The compact, low-profile design allows the Mini-AVR to be installed out of view, minimizing any intrusion into the living space. Please keep in mind that the AVA-Series amplifiers support Bluetooth® audio so that any audio content from a phone, tablet, or computer can be easily played. If planning on using the Bluetooth® audio input, make sure to verify the Bluetooth® functional range before finalizing a mounting location. Depending on the construction of the TV, wall box, building materials, etc., the range of the internal Bluetooth® receiver may be impacted.
