With the Basic +  we took the teachersPet Basic  and  integrated a higher power 3 speaker sound system that has the ability to fill an auditorium or gym with crystal clear audio. You will be able to reinforce your spoken word with the  included microphone with extra long cables (wireless option  also available). Sound from the included DVD / VCR can be mixed in as well making this a very flexible pet! We have also included a lock box on this unit to store your mics and cables.
