Yes, balanced.
Microphones connect to a transformer primary or a differential circuit and they are connected using a balanced connection.
A differential circuit accepts a balanced connection.
A transformer primary accepts a balanced connection.
Some people confuse the terms "balanced" and "differential".
The term "differential" describes a circuit.
The term "balanced" describes a way of connecting a source to a differential circuit or a transformer.
With a transformer you can have a fully balanced connection without having a differential circuit.
Some equipment has a input stage circuit and a output stage circuit that are differential while the rest of the circuit in the unit is single ended.
Other equipment uses input and output transformers while the rest of the circuit in the unit is single ended.
Both of these type units accept fully balanced input and output connections.
Some special equipment is fully differential from input to output.
Some using input and output transformers with fully differential circuits in between and some using active differential circuits from input to output and no transformers.
All of these will accept fully balanced connections.
In the studio and at home I have used, maintained and repaired units using all of the type circuits described above.
