VCRI

The VCRI and VCSI are automatic impedance matching volume controls. That means multiple VCs and speaker pair can be connected to an appropriately powered amplifier. There are no jumper or switch settings as long as the overall load does not exceed the amps capability.
1. Use the same basic instructions for connecting the VCs to speakers as described in ‘Connections’.
2. Connect all L+ wires to the L+terminal on the amp. Connect All L- wires to the L- terminal on the amp. Connect all R+ wires to the R+ terminal on the amp. Connect All Rwires to the R- terminal on the amp.
3. Up to 6 VCRI/VCSI with one pair of 8 Ohm speakers per VC can be connected to a 4 Ohm capable amp as shown in the illustration.
4. Up to 4 pair of 8 Ohm speakers can be connected in parallel to a single VCRI/VCSI connected to a 2 Ohm capable amp
