INTRODUCTION 1 1. RB-DDA22 22 Way Stereo Digital Audio Distribution Amplifier Introduction Fig 1-1: RB-DDA22 Front Panel The unit has 5 inputs and you can select one of them to distribute to all of the 22 outputs.
1 INTRODUCTION IN TROD U C T I ON Operating Mode In ‘operating mode’, the central button LED is unlit. The unit selects this mode when a valid input signal has been present and no button presses have been made for 8 seconds. The LEDs around the button illuminate amber to directly indicate the following frequencies 32, 44.1, 48, 88.2, 96, 176.4 & 192 kHz. If the input is at a non-standard frequency then the unit will indicate both the frequencies either side of the incoming frequency – e.g.
