RM-4C8-E1B Reference Monitor, 4 LED Meters, 8 Channel Inputs &
Dual Source Selectors With Dolby Decoder Card, BNC Input/Output
This version of the Reference Monitor is the RM-4C8 with the RM-E1B expansion card already fitted. So, it has all of the features of the RM-4C8 as standard together with Dolby Decoding.
The RM-E1B adds to the unit a 75ohm unbalanced AES/EBU input and output on BNC connectors with the output acting as a loop-through of the input. The BNC input can decode a Dolby E or Dolby Digital audio stream allowing you to monitor visually 8 or 5.1 audio channels respectively and to monitor audibly any 2 of those channels. By pressing the left hand source select control, you can select the Dolby input. If a Dolby E or Dolby Digital input is detected, the Channels (CHANS) button flashes to indicate that decoding is possible. Pressing the CHANS button displays the Dolby Digital 5.1 or Dolby E 8 channel signal, using the 4 bar-graph meters. Each meter is split into 2 sections allowing you to view L, R, C, LFE, Ls, Rs for Dolby Digital and an additional Lt, Rt for Dolby E. Full Dolby Metadata is available using the SCi remote control software. For a more detailed description of Dolby Decoding operation please refer to the Reference Monitor handbook.
