Operation
Media split mode
To switch the unit to media split mode, press the recessed MEDIA SPLIT switch on the rear panel; its yellow LED and also the one on the front panel will illuminate to show that the switch is on. In media split mode, the input to channel 8 - on both the front and rear panels - is distributed to all 16 electronically balanced outputs (rear panel) via its mic preamp, which is controlled via the channel 8 GAIN control knob; all of the meters will follow the output of channel 8.
Note: In media split mode, the transformer isolated outputs of channels 1 to 7 (front panel) still have the ability to act as independent isolated feeds, if required, via the associated secondary fixed gain mic preamps. If doing so, best practice is to set the unused mic gains to minimum.
Using the ground lift switches
If you are experiencing ground loop problems, switch on one or both of the ground lift switches, that is, OUTPUT A LIFT and OUTPUT B LIFT on the rear panel. Each ground lift switch lifts, or disconnects, globally its respective set of eight outputs (OUT A or OUT B) on all eight channels.
The ground lift switches are used to eliminate ground loop problems, which are caused by differences in ground potential between items of equipment; this creates a voltage difference in the grounds of the equipment and results in a mains frequency hum within the system.
With a ground lift switch switched on, pin 1 of each of its associated output XLRs will still be connected to chassis ground via capacitors. This provides an a.c. path to ground, while blocking any d.c. current flow resulting from a ground loop condition.
