The 2-channel controller will only be able to control two of the four channels at a time, so the user will need to switch between the channels as needed.

The versatility of a 4-channel amplifier makes it a popular choice for those looking to upgrade their sound system with more power and control. **

A 2-channel amplifier has two separate channels, allowing it to power two separate speakers or a single speaker with two separate inputs.

Additionally, they can be more difficult and expensive to maintain and repair compared to traditional piston engines. Ultimately, whether a rotary engine is "bad" depends on the specific needs and preferences of the user. **
