5 AES 2 [DW L and DW R]
The AES 2 input has two input jacks (XLR, female). In regular mode, the AES 2 DW L input
jack is used to connect a regular AES signal. This input then corresponds to the same spe-
cifications as the input AES 1.
However, the AES 2 input also supports Dual Wire (DW) mode, in which two AES jacks
operate together to double the sampling rate.The AES 2 input therefore has two XLR jacks.
In Dual Wire mode, the AES 2 DW L jack is used to connect the left channel and AES 2
DW R is used to connect the right channel. Dual Wire is automatically activated when a
mono channel is detected in the input signal from both AES 2 inputs. When Dual Wire is
active, the abbreviation “DW” is shown on the display (see page 15) to the left of the word
“Sample Rate”.
Balanced, 3-wire, 110 Ohm „twisted pair“ cables with XLR connectors are used for the
connection.
6 Word Clock
Mercury can be clocked to any connected digital input or to an external word clock. If you

7 FIX OUT
The FIX OUT is an analog balanced stereo output (XLR, male) which can be calibrated to all
common reference levels. See page 15 for more information on selecting reference levels.
8 VAR OUT
In addition to the regular stereo output FIX OUT, the Mercury has another analog symmet-
ric stereo output: VAR OUT
The same signal is applied to this as to the FIX OUT, but the level is variably adjustable.
Thus Mercury can also be used as a state-of-the-art monitor controller.
