Alesis MasterControl manual Audio Inputs and Outputs, „ Available Channels at Various Sample Rates

Page 31
All digital audio carried over the FireWire connection is 24- bit PCM data.
You can use either of the two FireWire ports on the back of the MasterControl. The other port can be used to attach
another FireWire-based computer peripheral, such as an external hard drive.

AUDIO INPUTS AND OUTPUTS

„Channels Sent from the MasterControl to the Computer

The FireWire port sends every available individual MasterControl channel to the computer. This means that, from the MasterControl, you can send a maximum of 26 channels: eight analog channels, 16 digital channels over the ADAT connections, and two digital channels over

the coaxial S/PDIF connection. The number of available channels will vary depending on (1) how you use the ADAT 2 / S/PDIF connection and (2) the sampling rate you set.

„ Channels Received from the Computer into the MasterControl

The Firewire port receives 6 channels back from the computer—a stereo audio stream for each of three channel pairs. From the MasterControl, you can freely assign these three stereo pairs to any of Output Sources A, B, and C as well as to Headphones 1 and 2.

If they are used, direct monitoring signals will be blended in with these channels. Using the talkback mic will “take over” these channels.

For more information on how these channels work and how to monitor them, refer to MONITORING &

CONTROL ROOM FEATURES.
