Connectivity
Now let´s plug in all necessary cabling and connect the whole playback system.
1. Yes, the LS1 needs power, so the active leg of each speaker has a power connector, that needs
to be plugged into a power outlet first. If you have the three-way system with the additional
subwoofer, you will only need to connect the subwoofer to the power outlet. The subwoofer has
an additional loop-thru connector for the power cable and with the subs we supply a short male-
to-female power cable that goes from this subwoofer loop-thru connector straight into the LS1
power input.
2. Now let´s hook up the LS1-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.
3. The supplied usb cable is connected between the usb-interface and a free usb-port of the
mac/pc that has the LS1 remote software installed.
4. Now we connect the left and right speaker 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.
5. Last but not least we take the little CAT5 „Loop Back Connector“ (which you find in the
accessory box) and plug this into the „digital thru / control thru“ socket of the right speaker.
-> Now both speakers are connected, so the two dsp´s in the electronics can communicate!
Please do not use a generic CAT5 loopback connector! If you misplaced your LS1 loopback connector,
please contact Grimm Audio for a replacement unit.
