Apollo FireWire Hardware Manual Interconnections

Advanced Setup

This diagram illustrates a more complex Apollo setup that might 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 UA’s

4-710d Four-Channel Tone-Blending Mic Preamp w/ Dynamics. The 4-710d performs A/D conversion on these

mics and their signals are digitally routed into Apollo via the ADAT Optical Interface. Apollo 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).

A digital recorder is connected to the S/PDIF outputs and a tuner is connected to analog line output 7.

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 via ADAT Lightpipe

• Apollo 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)

• If connecting to a Thunderbolt computer via the Thunderbolt Option Card, the FireWire connections

shown here would not be used
