The WAM-400 wireless automatic mixer is ideal for meetings, seminars, teleconferencing, house of worship services, broadcast and conference applications.

Receiver Installation and Connections

Installation:

For better operation the receiver should be at least 3ft. (1m) above the ground and at least 3ft. away from a wall or metal surface to minimize reflections.

Attached a pair of UHF antennas to the antenna input jacks, the antenna are normally positioned in the shape of a “V” (both 45°from vertical) for best reception.

Keep antennas away from noise sources such as computer, digital equipment, motors, automobiles and neon lights, as well as away from large metal objects.

Keep open space between the receiver and transmitter for better reception.

The transmitter should be at least 3ft. from the receiver.

Connections:

The switching power supply is designed to operate properly from any AC power source 100-240V,

50/60Hz without user adjustment. Simply connect the receiver to a standard AC power outlet, using only an IEC-type input cordset approved for the country use. Power to the unit is controlled by the front panel power switch.

There are two audio outputs on the rear panel: an XLR microphone output and a 1/4” (6.3mm) phone jack instrument output. The two isolated audio outputs permit simultaneous feeds to two different inputs. Use the appropriate shielded audio cable for connections between the receiver and the input(s) of the mixer or other equipment.

Networking Multiple Mixers

The first mixer (master)

The second mixer (slave)

The third mixer (slave)

If additional inputs are needed, more

WAM-400 mixers (as many as 5) can be linked using supplied link cables to control up 20 units microphones.

To link multiple mixers, connect the LINK

OUT of the first mixer to the LINK IN of the next mixer, finally connect the LINK OUT jack of the last mixer to the LINK IN jack of the first mixer.

As long as the link jacks of all mixers are connected, set up the master unit, then the automatic mixing functions will be opened, the mater unit can control the other 4 units salve, but each slave's functions of each channel can be used independently. Volume output of these 5 units is from the master unit.
