Barium Duo - Dual channel Reference Meter
Reference Signal Meter
Barium is available in two versions.
*  Barium is a single-channel reference bargraph meter with 20 LEDs
*  Barium Duo is a dual-channel reference bargraph meter with 2x 20 LEDs
The bargraph meters have:
*  42 dB range with peak hold
*  dBu and dBFS scale
Due to it’s very precise calibration, Barium can be perfectly used as reference meter.
As standard, the Barium meters are set to -18 dBFS = 0 dBu
This can be changed to —20 / -22 / -24 dBFS = 0 dBu, using the dip switch on the main PCB.
As you know, Octa / 500 modules are single-channel.
To get 2-channels in (left / right) Barium Duo comes with an XLR Female-to-Female adapter for your Octa / 500 rack.
Left channel comes from the input, right channel comes from the output (using the adapter).
Barium Duo is available with “Silver” or “Black” faceplate and can be used in the Interphase Octa Rack, the Ark console or in any 500-series rack
