Speaker Connections
TCS Compact Series enclosures are provided with a recessed connector panel housing a
single Neutrik Speakon NL4MP connector wired in parallel with a 4-way terminal strip.
Either can be used for the input, the other being available as an output for looping to
further TCS enclosures.

Note that looping out to additional enclosures has the effect of reducing the load
impedance on the amplifier. For example, two 8 ohm cabinets in parallel give a combined
total impedance of 4 ohms. Never connect loudspeakers whose total combined
impedance is lower than the amplifier’s recommended minimum load impedance. Do not
use the loop-out connection to connect other types of loudspeaker, especially when their
impedance is not known, as permanent damage could result!
The cable end Speakon NL4 connector should be wired as follows:
Positive output Pin 1 +
Negative output Pin 1 -
Please take care if XLRs, binding posts, or other dual connector systems, are used at the
amplifier end of the loudspeaker cables (jack plugs/sockets should not be used) where
there is a possibility of the cables being reversed. It is highly recommended that Neutrik
Speakon or other heavy duty non-reversible connectors are used.
