Apollo 8 Hardware Manual Interconnections 31
Advanced Setup
This diagram illustrates a more complex Apollo 8 setup that could be used for recording
an entire ensemble, utilizing both analog and digital I/O.
In addition to the connections in the previous example, four additional microphones
are connected to Universal Audio’s 4-710d Four-Channel Tone-Blending Mic Preamp
w/Dynamics. The 4-710d performs A/D conversion on these mics and the signals are
digitally routed into Apollo via the ADAT optical interface. Apollo 8 is the master clock
source, so the 4-710d is set to use external word clock (and a 75-ohm BNC word clock
cable is interconnected). ALT monitors are configured for comparing different speakers.
A stereo digital recorder is connected to the S/PDIF output, a tuner is connected to
analog line output 8, and a Thunderbolt hard drive is daisy-chained off Apollo 8.
Key points for this example:
• Mic/Line switch for channels 3 and 4 are set to MIC
• Four additional mic preamps from UA’s 4-710d are routed into Apollo 8 via ADAT
Lightpipe
• Apollo 8 is the master clock device; the 4-710d clock source is set to external
word clock and the 4-710d Termination switch is engaged (alternately, the
4-710d could be used as the master clock by setting the 4-710d to internal
clock, setting Apollo to external ADAT clock, and eliminating the word clock cable)
