Loudspeaker Connections
TCS 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, or in the case of the TCS-12M and TCS-15M wedge monitors via two Neutrik Speakon NL4MP connectors wired in parallel. 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 total load impedance on the amplifier. For example, two 8 ohm cabinets in parallel give a combined total impedance of 4 ohms. Never connect loudspeakers to a power amplifier whose total combined impedance is lower than the amplifier’s recommended minimum load impedance. Do not use the loop- out connection to connect any other type of loudspeaker as permanent damage may result!
The cable end Speakon connector should be wired as follows:
Positive output | Pin 1 | + |
| | |
Negative output | Pin 1 | - |
| | |
Please take care if XLR’s, 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 Speakons or other heavy duty non-reversible connectors are used.
