Line Outputs. The AudioBox 1818VSL has eight line outputs to route
to external devices, such as headphone amps and DJ mixers. Outputs
1 and 2 share their playback streams with the Main Outs. Outputs
7 and 8 share their playback streams with the headphone output.
Outputs 3 through 6 have independent playback streams.
Main Out. These are the main outputs for the AudioBox 1818VSL. The output level of
the Main Outs is controlled by the Main volume knob on the front of the unit.
MIDI I/O. MIDI stands for “Musical Instrument Digital Interface.” MIDI inputs
and outputs allow connection to, and communication with, external MIDI
equipment. One function of these ports is MIDI sequencing but the MIDI
protocol can be used for much more than instruments and sequencing.
NOTE: MIDI is not audio but is frequently used to trigger or control an audio
source (such as a plug-in or synthesizer). It’s important to ensure that your
MIDI data is correctly sent and received by the appropriate hardware or
software devices. If the devices generate audio, you may also need to return
the audio to an AudioBox 1818VSL input channel. Please consult the User’s
Manuals of your MIDI devices for help with MIDI setup and usage.
S/PDIF In and Out Jacks. The S/PDIF standard allows two channels of audio
to be transmitted at rates up to 24 bit, 96 kHz. The S/PDIF I/O also allows the
AudioBox 1818VSL to send and receive word clock to external digital devices.
Power User Tip: Remember to set “S/PDIF” as the Clock Source and set the sample
rate to correspond to the external device in the AudioBox VSL Setup Tab (Windows)
or in Audio MIDI Setup (OS X) when using the S/PDIF input for external sync.
ADAT–S/MUX Input and Output. These are ADAT–S/MUX connections for your
external digital devices. When recording or playing back at 44.1 kHz or 48 kHz, the
ADAT input and output will stream 8 channels. When recording or playing back at
88.2 kHz or 96 kHz, each connection will stream 4 channels. The ADAT–S/MUX I/O
also allows the AudioBox to send and receive word clock to external digital devices.
Power User Tip: Remember to select “ADAT ” as the Clock Source and set the sample
rate to correspond the external device in the AudioBox VSL Setup Tab (Windows)
or in Audio MIDI Setup (OS X) when using the ADAT input for external sync.
