choose this coupler, and you need to specify that the coupler comes with the
mAT-CK cable, or buy it extra.
Whether the mAT-50 tuner is equipped with a mAT-50-Y or mAT-50-M coupler,
it has two modes, Dedicated and General mode.
Dedicated:
When the coupler is connected to the "TUNER" socket of the
transmitter by a specific control cable, mAT-50 is a dedicated tuner. The
transmitter supplies power to the coupler and tuner via this cable, no
additional power supply is required, and keep the "DC" socket of the coupler
free.
General:
When the coupler is not connected to the "TUNER" socket of the
transmitter, mAT-50 is a general tuner. The coupler's "DC" power socket should
be connected to a 12-14V DC power supply. Tuner will work with any
transmitter.
The couplers mAT-50-M and mAT-50-Y have the same appearance. The
pictures below are their front and rear panels.
Front panel has 1 button and 4 indicators.
