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.
