Analog Inputs (Apollo 16)
Console’s 16 analog line inputs reflect the 16 channels of A/D conversion that are avail-
able in Apollo 16 (Apollo 16 does not have preamp channels).
Digital Inputs
Apollo
Console’s eight ADAT and two S/PDIF (stereo left and right) inputs work just like the ana-
log inputs, except they don’t have the extra the preamp and reference level settings that
are only available on the analog inputs.
Apollo Twin
Apollo Twin’s digital TOSLink input can accept ADAT or S/PDIF. Console’s inputs switch
to reflect the digital input type currently in use (the digital input preference is set in the
Console Settings window). The digital inputs work just like the analog inputs, except they
don’t have the extra the preamp and reference level settings that are only available on
the analog inputs.
Apollo 16
Console has two AES/EBU inputs (left and right). MADI inputs are not available in Con-
sole (MADI on Apollo 16 is used for multi-unit cascading only).
Sample Rate Conversion
Realtime sample rate conversion (“SR Convert”) is available on the
S/PDIF and AES/EBU inputs. This feature eliminates audio artifacts
(clicks, distortion, etc) that can occur when the sample rate of exter-
nal digital devices connected to the S/PDIF or AES/EBU inputs do not
match Apollo’s internal sample rate.
To enable realtime sample rate conversion on Apollo’s S/PDIF or AES/EBU inputs, click
the SR Convert button in Console’s associated channel strip. The feature is active when
the button is yellow.
Sample Rate Conversion notes:
• SR Convert is available on S/PDIF or AES/EBU inputs only (not ADAT or MADI)
• SR Convert applies to both L/R inputs (they can’t be individually enabled)
• SR Convert functions on both L/R inputs whether or not they are stereo linked
• SR Convert is unavailable when Apollo’s clock source is set to S/PDIF or AES/EBU
• SR Convert is unavailable on digital outputs
Virtual Inputs
The virtual input channels in Console do not reflect Apollo’s hardware inputs. Instead,
they receive signals from DAW outputs via Apollo’s device drivers, enabling Realtime
UAD Processing on any DAW output. This feature is especially useful when playing
virtual software instruments live through UAD plug-ins because it reduces I/O buffering
latency. For complete details about this feature, see
