6. Installation of the loop and amplifier WPI 1000.
Induction loop should be made with a wire with a thickness of 1 to 2.5 mm2. The maximum loop area is
1300 m2, with a maximum dimension of the short side may not exceed 30m.
The Loop installing-height should not exceed 1 m above the ground.
The loop should be connected to the clamp [15], and for its control we have the socket [16]. XLR sockets
[18], [21], [23] are to connect microphones or other line sources, at the same time setting the switches [19],
[20], [22] in the desired position. The Phantom power we user by condenser microphones
In the event when the amplifier is damage:
