Speaker Connectors:
TM There are three Speakon /Jack combination sockets provided one each rated at 2 Ohms, 4 Ohms and 8 Ohms total load
impedance. Only one of the connectors should be used at any one time. It is very important to observe correct speaker matching
and connection to avoid damage to your amplifier.
TM When using Speakon connectors they should be wired 1+ to the positive speaker terminal and 1- to the negative terminal 2+
and 2- are unused and not connected within the amplifier.
Make sure the impedance of your cabinets matches the
setting on your amplifier. Improper impedance matching will
result in reduced power output and compromised sound at
best and amplifier failure/premature tube failure at worst.
Laney recommend the use good quality loudspeaker leads
TM fitted with Speakon connectors, cheap leads are often not up
to the job of handling the large requirements for loudspeakers
and can often short out, or go open circuit. Tube amps don't
like running into an open circuit.
