The above shall be for a setup of :
Amplifier 1 and 2 with same input source ; thus only input port of channel 1 is connected.
The Link Switch 1 is switched to link position.
Amplifier 3 and 4 shall have separate BGM source and their outputs shall be connected to the
respective amplifier inputs.
Link Switches 2 and 3 shall be at OPEN position.
IF ONLY A SOURCE IS TO BE CONNECTED TO ALL AMPLIFIERS :
In the case that a single source is used for the whole installation, connect only to channel 1 and set all
the link switches to LINK position.
NOTE :
Input and Output signal from AX3700 shall have unity gain. Therefore a single source shall be limited to
max 6 output channels. If a source were to be connected to more than 6 amplifiers, it is recommended
that a distribution amplifier is used before connecting it to the AX3700 input port.
Having a source connected directly to more than 6 amplifiers may cause impedance drop, probably
causing distorted sound quality as well as signal drop.
