The INTUPAK VAA22 is the smallest and most unobtrusive solution to audio connectivity and preamplification in any room. It offers three audio sources, starting with a 3.5mm stereo TRS input, complemented by a Linkoustic wireless audio link input, and completed by a microphone input. All sources can be mixed at the desired ratio, and the master volume can be set by a large dial. The microphone input offers extra versatility with its on/off switch, tone control and adjustable talkover (priority) feature, allowing to automatically attenuate the program material when speaking into the microphone. The VAA22 is highly configurable via internal jumpers for Mic gain, Mic HPF, Mic phantom power and Master stereo/mono settings. The VAA22 uses the optional SPA22 remote power supply station as it does not include any internal power supply.
