Channel divider for 105 series 2-3 channel multi-amplifier.
The CF 105 can be used in 2-channel or 3-channel multi-amp systems as the amplifier is upgraded.
The 10-point crossover frequency allows you to set the optimum crossover frequency. It is also possible to turn it OFF.
The output stage is equipped with volume type level control for each terminal.
PNP type silicon planar transistor is used. Compared with the conventional NPN type silicon transistor, it has a feature of low noise in the middle and high range.
It is equipped with an SEA type low booster. If you use a multi-amp system instead of a general speaker system, you may feel low bass. To compensate for this, we have installed a low booster unit that can be switched and adjusted.
Equipped with a 3D switch, it is also compatible with 3D system. In this case, the circuit is configured to mix the Low output.
Output impedance is reduced by using a two stage direct-coupled output circuit with emitter-follower circuit and deep NF for each channel. This reduces the effect of extending the output signal with a cable.
There was a wooden case as an option sold separately.
