DTP CrossPoint 4K Series Matrix Switchers • Matrix Software 110
AV matrix block (see figure 53 on page 97,
C
)
NOTE: The figure at right shows the matrix size. Other models have 8
inputs and either 6, 4, or 2 outputs.
The AV matrix block displays the current tie configuration of either the
program emulation (Emulate mode) or the connected matrix switcher (Live
mode) and provides a way to make or break ties.
• To create a tie, drag a line from an input node ( ) to one or more
output nodes.
• To tie an input to all outputs, right-click an input node and select
Connect To All Outputs.
• The Legend panel identifies the type of tie: Audio Only (audio
breakaway), Video and Audio I/O (audio follow), or Video I/O (video
breakaway) . Click the legend link to select the type of tie.
• To remove a tie, click an input or output node and press the keyboard
<Delete> key or right-click an input or output node and select
Delete All Connections (for an input node) or Delete Connection
(for an output node).
Virtual returns inputs controls (see figure 53,
D
)
* FBS on virtual returns A through D only
The virtual returns input processor chain makes adjustments to inputs on the virtual bus
from within the DTP CrossPoint switcher.
FBS (feedback suppressor) block (Virtual Returns A through D only) —
The feedback suppressor processor block, when inserted, detects
feedback on a virtual return channel, and uses a set of fixed and dynamic filters to
counteract the frequency peaks at the detected feedback frequencies. You may possibly
achieve an additional 3 dB to 9 dB of mic gain where feedback would have otherwise
prevented these levels.
Filter block — The filter processor block, when first inserted, provides
one of four filter selections; additional filters can be then be added. The
available filters and the process for adding additional filters are as
described for the Line audio Filter block on page 103.
NOTE: Selecting Bass & Treble Filter inserts two separate filters.
Dynamics block
— The dynamics processor block, when inserted,
provides one of four dynamic processors. The available processors are as
described for the Line audio Dynamics block on page 104.
Delay block — The delay processor block, when inserted, provides a means
to delay the audio signal to sync it to video. The delay processor block is
identical to as described for the Line audio Delay block on page 104.
Gain control (pre-mixer) — The always-present gain control provides a fader with a
gain range of 12 dB to -100 dB, adjustable in 0.1 dB increments. The Gain block is
identical to as described for the Mic/line inputs signals Gain block on page 101.
