output using the SDI 2 bypass option only (see “Specifying your output

settings” on page 18).

• When you select the

Channel 1, Channel 2, 3D, Analysis, or Multiplex

option for a given output (see “Specifying your output settings” on page 18),

channel 1 and/or channel 2 is output using the current MC-100 settings. If

you want to output an input video signal without applying the MC-100

settings, choose the

SDI 1 bypass or SDI 2 bypass output option instead.

Amplifying input signals

MC-100 also functions as an input signal amplifier. Input signals connected to

MC-100 are automatically amplified within MC-100. This allows you to transfer

the SDI and HDMI output signals over greater distances. The distances for the

different input types are as follows:

• SD 300 meters (984 feet)

• HD 100 meters (328 feet)

• 3G 70 meters (229 feet)

Time base correction and synchronization

When input sources are connected to SDI 1 and SDI 2, MC-100’s time base

corrector ensures that the two video signals are synchronized at the output by

using the video signal that is set as the reference source (see “Specifying your

input settings” on page 16) to correct the other video signal. MC-100’s time base

does not correct the audio portion of the signal.

¦NoteThe time base corrector does not apply when using the SDI 1 bypass or

SDI 2 bypass output setting (see “Specifying your output settings” on page 18).

This means that if the two input sources are not synchronized using an external

reference source, the input signals may not be synchronized at the output.

Depending on the amount of discrepancy between the two input signal clocks,

the input signal that is not set as the reference source may not be output.

Loss-of-signal switcher

The loss-of-signal switcher feature enables MC-100 to automatically switch to a

different channel if it detects a signal loss on a main channel. This feature is

supported on the SDI 4 output only.

How it works

Let’s say you have a primary and an offline HD-SDI video signal connected to

SDI 1 and SDI 2 respectively. You then set SDI 3, SDI 4, and the HDMI output

(optional) to

Channel 1 in the settings menu.
