The TLM 193 is the cardioid only version of the TLM 170. It uses the same K 89 capsule (also found in the U 89) and has a very linear, transparent sound. The K 89 is what some consider a “medium sized” diaphragm capsule; it has the fast transient response of a small diaphragm condenser along with a smoother top end you’d expect from a larger diaphragm. The TLM 193 also has very low self noise, making it an excellent choice on quiet sources.
