Apollo Software Manual Chapter 4: Console Reference 65
The setting controls an attenuation pad for the input channel. When set to +4 dBu, the
pad is engaged and the channel can accept a higher signal level before the A/D converter
clips. Select -10 dBV when lower input signal levels are used.
Tip: To adjust signal incoming levels for Apollo’s analog inputs that don’t have
preamps, use the output level controls of the devices that are connected to those
inputs.
Tip: Additional gain can be added to input signals by inserting UAD plug-ins and
adjusting the gain structure within the plug-ins.
The availability and behavior of the reference level control depends on the hardware
model, as described below.
Apollo & Apollo 8 – The reference level for analog input channels 5 & 6 and 7 & 8
are linked in Apollo’s hardware. Therefore, the reference level in Console can only be
switched according to these stereo pairs.
Apollo 16 – The reference level for all analog input channels 1 – 16 can be individually
switched.
Sample Rate Convert
Realtime sample rate conversion (“SR CONVERT”) is available on
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 switch in Console’s associated channel strip. Click again to disable the
feature.
Sample Rate Conversion notes:
• SR Convert is available on S/PDIF or AES/EBU inputs only
• 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
UAD Plug-In Inserts
All Console plug-in insert slots operate the same way. For complete details
on all insert functionality and operations, see “Chapter 5: UAD Plug-In
Inserts” beginning on page 99.
