IntRoDUCtIon Thank you for purchasing the Focusrite Red 16Line. Red 16Line is a dual Thunderbolt 3 & Pro Tools | HD audio interface and preamplifier, suitable for a wide range of audio integration applications. The Red 16Line features Mic, Line and Instrument analogue inputs and 22 analogue output channels –...
• The Meter button calls up the selection menu for the level meters onto the output Display. • The Monitor button assigns the output encoder to the monitor loudspeaker functions. Pressing the Meter and Monitor buttons simultaneously enters Red 16Line’s Global configuration menu, where host, clock, power-up and network settings are assigned.
• Word Clock – output provides an output of the chosen system clock reference. • Loop sync I/o sockets allow Red 16Line to integrate with a standard Pro Tools system I/O chain. • Dual thunderbolt 3 Connection. Two ports allow either direct or chained connection to your workstation.
Red 16Line dimensions are illustrated in the diagram above. Red 16Line requires 1U of vertical rack space and at least 400mm of rack depth, to allow for cables. Red 16Line weighs 5.04kg and for installations in a fixed environment (eg., a studio), the front-panel rack mountings will provide adequate support.
Inputs Red 16Line has the capacity to accommodate sixteen analogue inputs, two independent 8-channel ADAT inputs, a 2-channel S/PDIF input plus 32 Dante input channels. (Additionally, an internal 2-channel loopback signal can be added as an extra stereo input – see page 13 for details.) analogue Inputs Analogue input channels 1 &...

TOSLINK connectors. Loopback Input The Red 16Line’s virtual Loopback inputs allow you to record any mix within Focusrite Control back into your DAW. This could be the audio output of another software application, or an entire monitor mix within Focusrite Control including analogue or digital inputs mixed with any playback signals that you wish to capture in your DAW.

Connection Confirm that Red 16Line’s Host setting is set to ‘Thunderbolt’, see Global Host Settings on page 20. Two Thunderbolt 3 connectors are located on the rear panel. Connect to the host or into the chain using standard Thunderbolt cables (one supplied).
Connection Confirm that Red 16Line’s Host setting is set to ‘Pro Tools’, see Global Host Settings on page 20. Connect both rear panel PRIMARY ports to a Pro Tools | HDX card using Mini DigiLink cables. Each Pro Tools | HDX PCI/PCIe card provides two Mini DigiLink ports (giving the card a capacity of 64 inputs and 64 outputs), thus one Red 16Line may be connected to each card.
