6) Right channel balanced input on euroblock. Items 4, 5 and 6 are hardwired internally and can
be used to create a daisy chain for connecting even more amplifiers.
7) Left channel balanced input on euroblock. Items 7, 8 and 9 are hardwired internally and can
be used to create a daisy chain for connecting even more amplifiers.
8) Left channel XLR male input signal connector.
9) Left channel XLR female input connector.
10) Subwoofer output on 4 pole Speakon® connector. Pins 1+ and 2+, as well as 1- and
2- are connected in parallel. Minimum load impedance is 4 ohms on each Speakon®
connector.
11) Subwoofer output on 4 pole Speakon® connector. 1+ and 2+, as well as 1- and 2- are
connected in parallel. This connector carries exactly the same signal as 10 and is hardwired
internally. Minimum load impedance is 4 ohms on each connector. In case you want to use
2 pieces 4 ohm subwoofers, then wire them independently. One sub connected to 10, the
second to 11. Always make use of the 4 connection pins (1+ and 2+, 1- and 2-) to avoid
contact burn-in caused by the extreme currents flowing through these connectors!
12) Right speaker output on 4 pole Speakon® connector. 1+ and 2+, as well as 1- and 2- are
connected in parallel. Always make use of the 4 connection pins (1+ and 2+, 1- and 2-) to
avoid contact burn-in caused by the extreme currents flowing through these connectors!
13) Left speaker output 4 pole Speakon® connector. 1+ and 2+, as well as 1- and 2- are
connected in parallel. Always make use of the 4 connection pins (1+ and 2+, 1- and 2-) to
avoid contact burn-in caused by the extreme currents flowing through these connectors!
14) Ground lift switch: this switch normally stays in the “EARTH” position. In case you have
created a ground loop, you can switch it to the “LIFT” position, to help you find the source of
the ground loop. However, when the ground loop is severe, activating the switch will not help
much, and eventually one or more system components may fail. When excessive noise, hum
or system instability occurs, power off all devices, and start connecting all units individually.
Tuners connected to an outdoor antenna or a cable signal distribution system, computers,
serial control devices and laptops are the usual suspects.
15) Mains inlet connector: plug in the supplied mains cable here. The mains fuse is located
inside the unit and can be accessed by removing the top cover of the unit. For authorized
personnel only! When the fuse blows regularly, check your system first, remove any ground
loops caused by faulty installation. Always check for short circuits on your speaker lines,
audio signal lines and other connections.
