| RTW was engaged in digital audio technology very early, so SonyŽ's Digital-Audio-Processor PCM-F1 NTSC (upper unit in the image) became part of the product range. This device was also available as a modified version in order to connect an Analog & Digital Interface (below left) developed by RTW. This interface expanded the functions of PCM-F1 for studio applications to adjust the inputs and outputs for balanced +6 dBm connection technology and to allow direct digital copies to SonyŽ's professional Processor 1610. The interface also could be used as power supply for two portable SonyŽ Betamax Videorecorder SL-2000 NTSC (below right). |
