Not for: Anyone who needs mic preamps.
What the AI looks for in Recording Signal A-D & D-A Converters
- Digital connection
- Match the converter's digital format to a free input on your interface: ADAT, S/PDIF, AES or USB. A converter is useless if your interface cannot receive its format.
- ADAT channel count at high sample rates
- One ADAT optical port carries 8 channels at 44.1 or 48 kHz, but only 4 channels at 88.2 or 96 kHz. Buyers often expect eight channels at 96 kHz and only get half.
- Clocking
- Make sure the converter has word clock in and out, and set exactly one device as the clock master. Clock mismatches cause clicks, dropouts and drift.
- Reference level
- Check that the converter's maximum level can be set to match your gear, typically +4 dBu professional or -10 dBV consumer. A mismatched level either clips the converter or wastes dynamic range.
- Mic preamps vs line-only
- Decide whether you need mic preamps or only line inputs before you buy. Line-only converters cannot record microphones directly.
Brands that matter
- RME: Reference converters known for stable drivers and clocking.
- Focusrite: Reliable ADAT preamp expanders.
- Behringer: The cheapest route to eight more channels.
- Ferrofish: Dense line-level ADAT converters.
- Apogee: Long-standing converter specialist.
- Lynx: High channel-count studio converters.
What to avoid
- Buying an ADAT expander for an interface that has no optical input
- Running two devices as clock master at the same time
Questions
Do I need 192 kHz?
Rarely. 24-bit audio at 44.1 or 48 kHz covers most recording, and higher rates reduce ADAT channel counts.
