DB25 Connectors

The RECORDING OUTS on the back of the Onyx 1220

provide balanced direct outputs for channels 1-12 on
two female DB25 connectors. These connectors are
pin-for-pin compatible with the analog (not TDIF) DB25
connectors found on TASCAM DTRS recorders, which
has become an industry standard for many professional
audio manufacturers. They are also the same pinout as the
analog cards for the Mackie D8B and hard disk recorders.

Normally, each DB25 connector provides eight bal-

anced line-level inputs or outputs. Since the Onyx 1220
has only 12 channels, the top DB25 connector (labeled
1-4) provides only four balanced direct outputs, while
the bottom connector (labeled 5-12) provides eight.

Several companies make DB25-to-DB25 cables specifi -

cally for audio, with proper shielding to reduce crosstalk
and noise.

DB25 cables that break out to XLR, 1/4" TRS, or TT

connectors for connecting to other mixers or audio gear
are also readily available. See your Mackie dealer for
details.
