Instrument input: The instrument jack is a locking quarter-inch connector used for connecting unbalanced

instrument cables to the M63. The input impedance of the instrument input jack is approximately one million

ohms. (1 MΩ)

INPUT XLR connectors: The Input XLR connectors provide balanced inputs for microphones with an input

impedance of approximately 1800 ohms. As is consistent with modern standards, pin 1 is connected to the

chassis ground, pin 2 is for the positive phase of the signal, and pin 3 is for the negative phase of the signal.

OUTPUT XLR connectors: The Output XLR connectors provide a balanced, line-level output sufﬁcient to drive

long cables and/or equipment with 600 ohm inputs, however the M63 will perform best when driving a higher

load impedance, such as a typical, modern 20 kΩ bridging input.
