How to set up a microphone in OBS for a professional television stream

Whether you’re a seasoned podcaster, a budding vlogger, or a casual gamer connecting with friends, a good microphone is only half the battle. To truly captivate your audience, you need to wield the power of microphone settings. Here’s why:
  • Be Heard, Not Heard From: Imagine trying to decipher a muffled conversation. Background noise from traffic, fans, or even your keyboard can quickly turn listeners away. Proper microphone settings filter out unwanted noise, ensuring your voice cuts through cleanly.
  • The Power of Perception: Crystal-clear audio creates a professional impression. Listeners subconsciously associate a well-configured microphone with quality content and a polished presenter.
  • A Sound Investment: A little time spent tweaking settings can significantly improve your audio quality. This is especially important for those relying on voice to engage audiences, like podcasters and YouTubers.

By taking control of your microphone settings, you’re not just affecting the sound – you’re shaping how listeners perceive you and your content. It’s a simple step that can take your voice from background noise to center stage.

How to configure Cisco switch using CLI

Step 1: Use an external emulator such as Telnet or a PuTTY to login to the switch.

  • Connect the switch to the computer by utilizing a console cable that is connected to the console port on the switch and the serial port on the computer.
  • Open puTTY -> under category choose serial -> in “Serial line to connect to” box provide the COM port to which the cable is connected -> configure the serial line transfer settings -> Click “Open“
  • Initial command prompt “Switch>” appears on the screen.
  • Type “enable” next to it and press “Enter”(we don’t need any password to enable at this stage).
  • This will take you to the “EXEC” mode, also known as the Global Configuration mode.
  • Go to configure mode using the configure terminal.
  • Input the configuration commands by typing one command per line.

Switch# configure terminal
Switch(config)#

Step 2: Provide a hostname for the switch to function in a particular network environment

The provided hostname should be unique within the network in order to facilitate easier identification of the switch. It is also advisable to adhere to any naming standards in order to easily categorize the devices with names.

Switch(config)#hostname <switch_name>
Switch(config)#hostname Cisco_switch_x

Step 3: Configure IP address management

To enable remote connectivity to the switch via SSH or Telnet, it is necessary to configure the IP address. Any VLAN can be selected for configuring the IP. Please utilize the following commands:

Switch(config)#interface vlan1
Switch(config-if)#ip address<ipaddress><mask>
Switch(config-if)#ip address 172.16.29.10 255.255.0.0

Step 4: Configure an administration password (enable secret password)

Configuring an administrative password for the privileged exec mode is essential to restrict access. Without this password, anyone with console credentials will have the ability to configure the switch.

Switch(config)#enable secret <password>
Switch(config)#enable secret P@$$w0^d

Note: This password will have to be given before entering into config mode once it is configured.

Step 5: Configure and change default switch credentials

Changing the default password of the switch is crucial, as it is widely known. To modify the password for an existing user, follow the commands provided below:

Switch(config)# username admin privilege 15 password <PASSWORD>
Switch(config)# username admin privilege 15 password P@$$w0^d

We can also create a new set of credentials as given above with desired privileges.

Step 6: Configure default gateway

In order to enable remote accessibility of the switch, it is necessary to configure the default gateway. Ensure that the provided default gateway is within the same network as the device (network router IP can be provided as gateway IP).

Switch(config)# ip default-gateway <IP-address>
Switch(config)# ip default-gateway 172.16.29.1
Switch# show ip route

Step 7: Configure password for console, Telnet, and aux ports

To establish a secure connection, it is essential to restrict access to the switch through all input ports.

For line console, enter below commands,

Switch(config)# line con 0
Switch(config-line)# password p@$$w0^d
Switch(config-line)# login
Switch(config)# exit

For line vty, enter below commands,

Switch(config)# line vty 0 4
Switch(config-line)# password p@$$w0^d
Switch(config-line)# login
Switch(config)# exit

For line aux, enter below commands,

Switch(config)# line aux 0
Switch(config-line)# password p@$$w0^d
Switch(config-line)# login
Switch(config)# exit

Step 8: Configure static route

In the absence of entries in the dynamic routing table or when there is no specific route available, the switches are capable of forwarding packets via the configured static route.

Switch(config)# ip route <dest_IP_address> <mask>
Switch(config)# ip route 172.16.29.59 255.255.0.0
Switch# show running-config

Step 9: Configure interface description

We can configure interface description using below commands

Switch(config)#interface fastethernet 0/1
Switch(config-if)#description Development VLAN

Step 10: Set Duplex mode

The duplex mode governs the data transmission between the switches and the endpoint. When set to full duplex, the switch is capable of both sending and receiving data from the endpoint simultaneously.

Switch(config-if)#duplex full

Step 11: Save the configuration

Switch#write memory
Building configuration… [OK]
Switch#
