INTRODUCTION
Thank you for your purchase of the ROLLS RDB109 SOUND CENTER.
The RDB109 is an audio distribution device with a single balanced XLR
line-level input, distributed via transformer isolation to ten balanced XLR
outputs.
OPERATION
Connect the input source to the INPUT of the RDB109. This may be a
line level or consumer level signal. We do not recommend connecting a
microphone directly into the RDB109 INPUT. Connect the RDB109 OUT-
PUTs to the inputs of the recording, broadcasting, etc. devices.
