To Link two 552s together:
1. Connect the Link I/O of 552 A to the Link I/O of 552 B using a TA5F to TA5F cable (Sound Devices XL-
TA55 optional accessory). This will send the stereo mix of each 552 directly to the stereo output bus of
both 552s.

2. Monitor the stereo sum of all ten input channels from either 552 headphone monitor.
3. Adjust the levels on each mixer accordingly.
Linking to Other Mixers
The Link I/O function allows the 552 to be linked to a Sound Devices 302, 442, or MixPre mixer for
applications requiring higher input channel counts. When the 522 is linked with another Sound
Devices mixer, all input channels will be present on the stereo outputs of the 552. Return audio and
PFL only occur on the headphone output of the mixer that it is performed on. The 552 Link I/O con-
nector is an unbalanced TA5M wired pin-1 = HP L, pin-2 = HP R, pin-3 = Mix R, pin-4 = Mix L, pin-5
= Link detection/ground.
Linking to a 302 or 442
The Tape Out/Mix Out of a 302 is an unbalanced stereo TA3F connector wired pin-1 = ground, pin-2
= Left, pin-3 = Right. The 442 has two Tape Out/Mix Out connectors, 3.5 mm and TA3. For the most
secure connection use the TA3 Tape Out/Mix Out connector. The TA3 is wired pin-1 = ground, pin-2
= Left, pin-3 = Right. For details on the 3.5 mm connection see Linking to a MixPre.
Sound Devices XL-TA35 is a 12-inch, TA5F to TA3F accessory cable used to link Sound Devices 302
and 442 mixers to the 552. For more details see Accessories.
To link a Sound Devices 302 or 442 to a 552:

TA35 cable. This sends the stereo mix of both mixers directly to the stereo output bus of the 552.
