Connector Pin-Outs & IO Specifications
The following connectors appear either on the rear panel or front buffer.
6.4.1
Mic/Line In
3-pin XLR connector, female.
All MIC/LINE IN connections are electronically balanced and floating (suitable for balanced or unbalanced use). They feature a
discrete class-A preamplifier with superb performance at both low (mic) and high (line) levels. In addition to variable
microphone pre-amp gain, each input comes with switchable 48V phantom power, a high-pass filter and 20dB PAD. The
maximum analog input level (with the PAD enabled) is +24dBu.
6.4.2
Talkback (TB)
3-pin XLR connector, male.
This connector is wired from the 3-pin female XLR Talkback connector on the front panel.
6.4.3
Line Out
3-pin XLR connector, male.
All LINE OUT connections are electronically balanced and floating (suitable for balanced or unbalanced use). For LINE OUTs,
the maximum analog level can be adjusted to +12, +15, +18, +21 or +24 dBu relative to digital full scale (dBFS). This is a
factory-configured setting; +24dBu is recommended.
For connection to an unbalanced input stage one line needs to be shorted to ground (hot or cold) like with a transformer-
coupled output stage. The level will remain the same as with a balanced load.
