Located on the rear of the console is an array of 10 DIP switches, corresponding to the 10 inputs of Blue 5c.
Monitor muting is enabled for the given input by placing the respective DIP switch in the ON position. When
the input is active and the cooresponding channel is ON, the monitors will be muted. This is commonly
called, “Input Followed Muting”.

Monitor level is controlled by a fader located on the right side of the unit.
4.8.1 Connecting Monitor Amplifiers
Most modern power amplifiers need only a small amount of voltage to drive them to maximum output,
which in many cases is greater than the power handling capacity of the monitor speakers. The low input
sensitivity of these amplifiers is easily exceeded by the output voltage capability of most console outputs, so
the installer is advised to consider protecting studio speakers by matching the output voltage of the console to
the input requirements of the monitor amp.
Recommended practice calls for setting control room and studio monitor amplifier gains at installation, after
which the amplifier controls are secured from tampering. The gain of the monitor amplifiers is set by
determining the maximum voltage at the console's output, with its associated level control wide open. The
gain of the monitor amplifier is set to reach maximum output (or maximum speaker power handling
capability) when this voltage is presented to its input.
This is accomplished easily when the monitor amplifier has a simple attenuator pad level control across its
input. However, most amplifiers today have a preliminary input stage before any level controls (consult your
amplifier schematics). If this is the case, full console output can overload an amplifier input causing serious
distortion and possible speaker damage. The preferred solution is to install a resistive pad at the amplifier
input to reduce the console output to the desired voltage.
!! WARNING !!
Leaving the monitor speakers active while a control room Mic is ON may
result in feedback and equipment damage.
