Status Information

»STATUS« Area
This area displays different system conditions of your MC-3+. There is no
access for changing settings.

»LOCK«
This blue LED lights when the internal PLL circuit has detected the incoming
clock reference signal as valid. If the reference signal is unstable or lost, the
»LOCK« LED does not light.

»HOLD«
This red LED lights when the external reference clock signal is interrupted
or lost. The frequency synthesizer of the MC-3+ keeps generating all output
signals continuously, based on the last incoming clock rate. Thus, your
studio set-up receives non-interrupted clock supply, regardless if a valid
external referecne signal is present, unstable or lost. Re-synchronization is
carried out without affecting any of the outputs signals critically.

»AUDIO«
This red LED lights when a valid AES3/11 or S/P-DIF optical or coaxial digital
audio reference signal is detected at the corresponding input.

»CLOCK

« Area

This area displays the clock rate of the incoming clock or digital audio
reference signal. The following basis reference clock rates are supported
and will be analyzed:

32.0kHz

44.1kHz

48.0kHz

88.2kHz

96.0kHz

176.4kHz

192.0kHz

Supported Input Clock Rates

10.0MHz

Generic Functions

There are two additional functions which influence the working of your
whole MC-3+ Smart Clock:

Front Panel lock out + LED shut down

When pressing both front panel keys together at one time, all LEDs will
shut down except the »POWER« and »LOCK« LEDs. Additionally, the
functions of both keys are also blocked to prevent unauthorized operation,
which is important during e.g. live events.

To reactivate the keys and the LEDs, please press both keys for apperox.
four seconds until all LEDs light again.

Factory Reset

You can reset the operating system of your MC-3+ Smart Clock to the
initial status by switching on the unit while pressing the »MENU« key
simultaneously.
