company inspect the unit and the box at your location. Count the pieces! Don't throw out the boxes and packing material until you are sure you have everything that is coming to you. The amplifiers need either their own separately ordered WA100 power supply or a DC cable,
Rack and desk mounting hardware may be packed in with the unit even though ordered separately. Wall mount power supplies must be ordered separately but may either be included with the unit or shipped in their own box.
MOUNTING
Single desk mounting kits consist of a pair of angled base plates that mount under the lower front and rear cover screws of a single unit, to raise and to tilt it for easy use. In addition, one or more sets of vertical stacking plates, mounting to the upper front and rear cover screws of the bottom unit, allow multiple units to be stacked. Several units can be desk mounted

WIRING
AUDIO CONNECTIONS
Balanced XLR type inputs and outputs are wired per figure 1 with pins 2 as HI and pins 3 as LOW. Pin 1 is the cable shield and ground connection. Pin 1 is grounded as shipped but may be floated to interrupt a hum producing ground loop by opening the unit and clipping out the GND LIFT jumpers. Unbalanced lines use pin 2 as HI and ground pins 3 and 1.
Active balanced outputs and inputs require a reference ground connection to the source or receiving device for proper operation. This ground can be provided by the rack frame or a studio buss connection if it is not carried through by the output cable shield.
GROUNDING
Operation in high RF broadcast environments requires special attention to grounding and shielding. The chassis must be grounded directly to a good, low impedance studio ground system. Input and output connections must be properly
