8. CHANGING TO HIGH IMPEDANCE
The SR-S4 series speakers can be used for high-impedance applications with the installation of the optional
MT-S0601 Matching Transformer.
To install the MT-S0601 transformer, remove the blank panel
located on the speaker's rear panel.
For details regarding mounting procedures, refer to the
instruction manual enclosed with the MT-S0601.
Note
The speaker cannot be used in combination with the matching
transformer when driven by a bi-amplifier.
To change the tap, refer to the instruction manual enclosed with the MT-S0601.
The diagram below is an internal wiring when the matching transformer is installed.
