To connect the eHSA4-60 amplifier to high impedance lines, you need to connect the loudspeaker line to the amplifier's 0V and 70V terminals for a 70V line or 0V and 100V terminals for a 100V line. Make sure to use the Euroblock connectors provided on the rear panel for these connections.

For low impedance lines, you should connect the speaker line to the Lo-Z ("+" and "-") terminals on the amplifier. Each output channel is independent, so you can use either high or low impedance connections regardless of how the other outputs are connected.

It's important to note that if you want to combine high and low impedance connections in the same channel using the two connectors of the same channel, you need to consider the load you are connecting to the terminals. The amplifier can deliver a maximum of 60W, so make sure not to exceed this power limit. For example, if you connect a 4Ω load to the low impedance connectors, you should not connect any additional load to the 70/100V terminals to avoid overloading the amplifier. However, if you connect an 8Ω load to the low impedance connectors, you can connect a line of up to 30W to the 70/100V terminals.

Remember to never connect the "-" terminal of the Lo-Z output together with the 0V terminal of the 70/100V line output. Also, use good quality, sufficiently sized, and short connection cables between the amplifier outputs and the loudspeakers for optimal performance.
