Source-Connect Pro/Pro X 3.9 at a first glance

When you first open Source-Connect Pro or Source-Connect Pro 3.9 after logging in, you will see the following interface by default:

Connection status: the status of your user in Source-Connect.
1. Available: if there are no connectivity issues and you are not connected to any other user the status should read “Available”.
2. "Connected to": during a Source-Connect session, the “Connections” text will change to “connected to: <username>”.
3. Unavailable: if you are having network issues (temporary or not), you will see your connection status change to “unavailable”. Other users will not be able to connect to you at this time.
Connection time: the session duration time.
Connect button: clicking this button will start the Source-Connect session with your connection opponent.
Send meter: displays your send level in dB. It will be gray while you're not on a call. If the meter moves into the orange or red areas of the meter during a call, you are likely to experience sound distortions and a lower quality of your signal.
Mute send button: clicking the button will mute your send only.
Receive meter: displays your receive level in dB.
Mute receive button: clicking the button will mute your send only.
Login information: displays the account you are logged in with.
Contacts panel: the list of contacts you can connect to in Source-Connect along with their status in Source-Connect ("online" when they are available, “busy” if they are on a call, or “offline” when they do not have Source-Connect on).
Messages panel: the area where you will see messages sent to you by other Source-Connect users during a call and where you will be able to send messages in-call.
Settings panel: this panel contains all configuration items related to your Source-Connect settings. It will be opened and selected by default.
RTS panel: the menu where you can access the options which allow for remote ADR, music over dubbing and mix review sessions with picture/timeline lock. Read more about Remote Transport Sync in this article.
Q Manager panel: clicking this button will open up the companion Q Manager (Pro or Pro X) menu, the tool you can use to repair and replace any recorded files which contain dropouts due to network loss.
Collapse button: this button will collapse the panel you currently have open (contacts, messages, settings, RTS). It will not collapse the upper part of the application.
Audio I/O - input: the input dropdown contains the list of devices (either physical or virtual) available for you to select as your input device. This is the device you will use to send audio out from Source-Connect to your connection partner.
Audio I/O - sample rate: a dropdown where you will be able to select the sample rate you want to use. Keep in mind the sample rate should be supported by your audio devices.
Audio I/O - output: the output dropdown contains the list of devices (either physical or virtual) available for you to select as your output device. This is the device you will use to receive audio in Source-Connect from your connection partner.
Audio I/O - channels: the number of channels you will send/receive audio from. The number of channels you select will determine the audio input/output options you will see in the I/O dropdowns.
Send settings - bitrate: the bitrate for the audio you are sending out of Source-Connect.
Send settings - resilience: the ability of your system to recover from a fault (network or otherwise). By default, it will be set to 1.
Receive settings - buffer: the time it will take for your system to process incoming audio signal. It will be set to 200ms by default, but you can select an auto-buffer, fixed latency, or several different buffer size increments.
Receive settings - port: the UDP port Source-Connect will use to establish a connection.
Receive settings - Q restore: checking this box will turn on the Q restore function in the Q Manager.
Receive settings - Q replace: checking this box will turn on the Q replace function in the Q Manager.
Receive settings - port status: the status of your network ports. Read more about each of the possible port status in this article. If you are looking for instructions on how to map your ports, here is a step-by-step guide.
Receive settings - port test button: a button to test out the port you have entered in the “port” field.
Preferences - always on top: Source-Connect will appear as a floating window on top of other programs. This is useful when you are working in Pro Tools for example, and want to monitor the connection. This option helps to make Source-Connect ‘feel’ like a plug-in.
Preferences - alert: whether Source-Connect will alert you whenever the audio goes over specific decibels (determined by the "alert volume" setting). It will be set to a single alert by default, but you can change it to "repeat" or "none".
Preferences - alert volume: turning on the alert volume setting will alert you whenever the volume goes above specific decibels. The options range from 0db to -25db in 5db increments. It will be set to "0dB" by default.
Preferences - on connection request: there are three options available:
1. Ask: for all connections, ask me if I want to accept the call.
2. Accept last: the last person I accepted, always automatically accept them again.
3. Accept all: always automatically accept calls.
Preferences - Show offline contacts: if you find your Contacts list has become rather long, you can make it more manageable by unselecting the ‘Show offline contacts’ checkbox. This will now only show any of your Contacts who are logged in and can make it much easier to find the Contact you are looking for when starting a session.
Preferences - auto-login: when auto-login is checked, you are automatically logged in with your existing settings intact upon initializing Source-Connect. Each time you open a session with Source-Connect enabled, and auto-login checked, you will be automatically logged in and be ready to connect.
Preferences - logout button: clicking this button will log you out of Source-Connect.
