Connectivity
In this chapter we will inform you about how to connect all cables to setup the whole playback
system. Please follow these cabling instructions carefully.
1. Being an active system, the LS1 needs power, so the active leg of each speaker has an IEC
power connector that needs to be connected to a power outlet. If you have the three-way system
with the additional LS1s subwoofer, you will only need to connect the subwoofer to the power
outlet. More information about connecting the three way system with subwoofer can be found at
the end of this Connectivity chapter.
Warning! For your own safety, please use outlets with safety earth.
2. Now you can connect the LS1i USB interface to the speakers. In our example we will start with
the left speaker, so we connect the ’To LS1 control in‘ with the ’digital in 2 / control in‘ of
the left speaker via the CAT5 cable. In case this simplies your wiring, feel free to connect to the
right LS1 rst. In the Software Control Settings you can select which speaker is rst in the chain.
3. The supplied USB cable is connected from the usb-interface to a free USB port of the
pc that has the LS1 remote software installed.
4. Connect the LS1r Controller to the usb-interface. One of the supplied CAT5 cables goes from
the ’remote out‘ on the LS1r Controller to the ’remote control‘ input on the usb-interface.
5. Now connect the left and right LS1 with the second CAT5 cable, going from the
’digital thru / control thru‘ output of the left speaker to the ’digital in 2 / control in‘ of the
right speaker.
6. Last but not least, plug the little CAT5 ’Loop Back Connector‘ (that you can nd in the
accessory box) into the ’digital thru / control thru‘ socket of the right speaker. It 'closes the
loop' for the control data so the DSP's in the LS1's can communicate with the LS1r Controller and
the LS1i USB interface.
Please do not use a generic CAT5 loopback connector! If you misplaced your LS1 loopback connector,
please contact Grimm Audio for a replacement unit.
