This Beta VCR has an AUDIO DUB button or switch. It lets you record over and add (dubbing) audio to the NORMAL sound track. It occupies the top position in the stationary ACE assembly. This separate track can be used for instruction, translation, or a different audio forum. The picture can be viewed during dubbing. Betahi-fi stereo cannot be dubbed separately because it is imbedded in the video signal. ©Misterßetamax go to homepage
