Dual-channel reference bargraph meter by Interphase Audio
Barium Duo is a dual-channel Reference Peak Signal Meter.
The two rows of 20 LED’s each have a range of 42 dB with dBu and dBFS scale.
But as you know, 500 modules are single-channel.
To allow Barium Duo to read two channels, both input and output of the 500 module are used.
To get 2-channels in (left / right) Barium Duo comes with an XLR Female-to-Female adapter for your 500 rack.
Left channel comes from the input, right channel comes from the output (using the adapter).
As a consequence, Barium Duo does not have signal-through, so you’ll need to split the signal to feed Barium Duo.
