and Time Code For best performance, maintain balanced connections, and use high-quality,
low-capacitance, twisted-shielded pair cable.
When connecting to single-ended, unbalanced devices, connect the low side to
signal ground at the unbalanced piece of equipment.
For mono connection, connect the left and right input channels in parallel.
Be careful to keep input and output to all channels wired consistently. Out-of-
phase wiring can produce audible effects.
This interface requires balanced connections using high-quality, low-capaci-
tance, controlled-impedance, data communication, twisted-shielded pair cable.
It will not work reliably if microphone cable is used.
This interface is unbalanced but, because it carries digital signals, it requires the
use of 75
Ω
RG-59 coaxial cable.
Use commercially-available, consumer audio optical cable assemblies.
Use standard 5-pin DIN MIDI cable asemblies, available from your local dealer.
