Volume Control

This port can be used to control the volume and mute or unmute the audio for some 

Extron audio amplifiers with remote volume capability.
• Connect to an Extron audio ampifier 

to permit volume control via the 

MLC Plus 84.

• Do not exceed 25 VDC input voltage.

Settings to configure via software:

• 

Maximum and minimum voltage 

limits

• 

Soft Start mode:

 off or on (default) − to 

allow volume to gradually increase from 

mute to the previous level after muting 

or power-on to prevent loud audio bursts

NOTE:

  Use shielded cable and 

place the MLC Plus 84 as close 
as possible to the amplifier to 
avoid picking up background 
noise via the cable.

NOTE:

  When audio mute is active, the MLC Plus 84 

sets output voltage to 0 VDC, even if the voltage 
range (minimum and maximum voltage limits) have 
been set to levels above zero, such as 2 V to 8 V.

Step 5: Set up the MLC Plus 84 for Network Communication

1. 

Connect the PC that you will use for setup and the  
MLC Plus 84 to the same Ethernet subnetwork.  
For LAN connections for the MLC Plus 84, see 

Control and 

Power — LAN (Ethernet) and PoE

 on page 7.

2. 

Start Toolbelt and use it to set the IP address, subnet, 
gateway IP address, DHCP status, and related settings. 
Use the flowchart at right as a guide to setting up the 
controller for network use.

NOTE:

  When setting up DHCP during network 

configuration or if using a host name instead of 
an IP address, the user must enter a qualified 
host name (

Username.HostName.Domain

).  

For example: 

somename.somedomain.com

. 

Open the Toolbelt software. 

Start Device Discovery.

Toolbelt displays a list of all Extron control devices 

connected to the network.

Using the MAC address, locate the desired device 

in the list and select it.

Network Communication Setup

Connect the controller and PC to the same network. 

Apply power to all devices.

Use the Set IP feature in Toolbelt 

or

  

use the Toolbelt 

Manage

 > 

Network Settings

 tab 

feature to enter the IP address, subnet address, 

and gateway, then configure other network settings 

as needed.
