A channel divider developed for multi-channel amplifier applications and used in combination with BA-60, BA-90, etc.

The CD-5 consists of 13 transistors and diodes.
Two diodes are used for rectification, one transistor is used as a filter to eliminate ripple in the rectified voltage, and the remaining 10 transistors are 2SC-458LG (NPN type low-noise silicon transistor) used as a frequency filter.

It is used for 2-channel multi-amplifier and 3-channel multi-amplifier, and the terminal for full range is also mounted.

The crossover cutoff characteristics can be switched between 6dB/oct. and 12dB/oct. In this case, the filter is a CR type filter at 6dB/oct. and an emitter-follower type NF filter at 12dB/oct.

Equipped with an unlock button.
The crossover frequency switch knob does not turn unless this button is pressed. This prevents inadvertent switching of the frequency and damage to the unit.
