Extron electronics MVC 121 Plus Operator's manual

EXTRON MVC121 Plus
Overview:
There are many uses of this driver, however the main purpose is to allow an installer to
easily overlay and mix up to 2 microphones (more if using another mixer in addition to
the MVC121 Plus) with program audio in a conference room scenario.
Features:
-2-Way RS-232 communication
-Discrete Volume & Mute Control & Feedback
-Easily Mix Up to 2 Microphones over Program Audio
-Includes 3 easy-to-use experience buttons for controlling microphone mute and vol-
ume levels via a Control interface
-Includes 1 universal microphone experience button for other applications
-Includes 3 Contact sensors to use for various programming events.
Installation:
Here is the suggested method of configuring the driver:
*FIRST* *IMPORTANT*
Load the saved MVC121+ configuration file (Included) into your MVC121 Plus to
properly configure the inputs, outputs, and gain levels of the MVC121 Plus
--Then--
Place the MVC121 Plus and microphone experience drivers into your Control4 driver
directory. (Typically C:\Users\yourusername\Documents\Control4\Drivers)
Create 1 room:
A) Conference Room
Add the MVC121 Plus driver to the project

Make a physical connection AND programming connection between your line level
program audio source and “Program Input (Input 3)” on the MVC121 Plus. In this
example, the television audio output is connected to the MVC121 Plus.
Set the MVC121 Plus as the Audio endpoint 1, Audio Volume 1 endpoint, Video Volume
1 endpoint, and Video's Audio endpoint 1 endpoints for the Conference Room:
Included in this driver package are 4 microphone experience buttons that are used to
control microphone levels and mute status from any Control4 navigator.

Search and add the “Microphone – Button (Mute)”, “Microphone – Button (Volume Up)”,
and “Microphone – Button (Volume Down)” drivers to the project.
Bind the Experience Buttons to the corresponding BUTTON_LINK connections on the
MVC 121 Plus
Make a physical and programming connection between the serial connection on the
MVC121 Plus and an open serial port on your Control4 devices.

*IMPORTANT*
Connect the MVC121 Plus Pinouts according to the manual to the proper RS-232
pinouts on the Control4 controller… If you are not able to properly communicate with the
MVC121 Plus, you may want to switch from strait-through to NULL wiring.
Enter a valid activation code on the Properties tap of the driver (Or use free 72 hour
trial)
Refresh Navigators
That's It!
*Don’t forget to “unhide”the microphone experience buttons in Navigator.
Additional Features:
1) You can change the color of the microphone experience buttons via the color
property on the properties tab.

2) Bind the BUTTON_LINK connections on the MVC121 Plus driver to Keypad
buttons to control volume and mute features of the microphones.
Don’t forget to set the color of the Button LEDs to:
a. LED Behavior = “Follow Connection”
b. On Color = Color you prefer LED to be when Mute is ON
c. Off Color = Color you prefer LED to be when Mute is OFF
3) The experience button called “Microphone – Button” is a universal experience
button with an analog audio connection that can be added to any Control4
system and configured as an analog audio source. Icon color can be chosen
from the Properties page as well.
Properties:
License Status: Displays the current license status of the driver according to Blackwire
Designs licensing server.
License Key: Input the license key from your Blackwire Designs dealer account and
press the “set” button to activate the driver.
Front Panel Lockout: Allows you to enable or disable the buttons/dials on the
front of the MVC121 Plus chassis.
Mic 1 Maximum Volume: Allows you to set the maximum volume level of
Microphone 1 in the overall audio mix
Mic 2 Maximum Volume: Allows you to set the maximum volume level of

Microphone 2 in the overall audio mix
Program Out Maximum Volume: Allows you to set the maximum volume
level of Program Audio in the overall audio mix
Command Delay: Displays the delay (in milliseconds) that Control4 will delay transmit-
ting consecutive RS-232 commands to the Extron MVC121 Plus device. If it is deter-
mined that some commands are ‘missed/ignored’ by the MVC121 Plus device, adjust
the command delay to speed up or slow down transmitted commands.
Debug Mode: Select a mode to debug the driver. Debug mode will revert to “off” after a
predetermined time.
Actions:
Clear Incoming Buffer: Forces all timers within the driver to expire. Use if it is deter-
mined the MVC121 Plus has stopped responding to commands.
Populate Info: Requests product details from the MVC121 Plus device and displays it on
the Properties tab. Use if the product details did not automatically populate on the
Properties tab.
Zero All Inputs/Outputs: Resets all volume levels to the original volume levels.
Kill All Timers: Forces all timers within the driver to expire. Use if it is determined the
MVC121 Plus has stopped responding to commands.
Limitations:
-Because of the limited volume range of the MVC121 Plus (-12db to 24db in 1db
increments), you will notice volume increments will go up my 3ish % when you adjust

the volume with Control4.Additionally, you may notice that when you set a Maximum
volume level via the properties page, the volume level you set might change slightly to
the nearest 3rd percentage. Additionally, the slider on Control4 navigators may be
slightly different than the actual volume levels due to rounding errors.
*IMPORTANT*
-Out of the box, the Digital inputs might continue to mute the inputs despite being
configured as “No Action” in the Extron configuration software. This is a firmware bug
confirmed by Extron. To fix this, change each trigger type to “Level, Lo”, apply, then
close the configure digital input box. Re-open the configure digital input menu, and set
each trigger type to “No Action/Off”. Hit apply and then close the configure digital input
box. The Digital inputs may result in undesired behavior if you skip this step.
-This driver requires Composer version 2.8.2 or higher. Using on a previous version
may work, however it is untested.
