BO-32DE, BO-16DX/IN and BO-16DX/OUT are versatile breakout boxes that provide up to 32 balanced analogue audio inputs/outputs for audio devices equipped with D-sub audio inputs/outputs like the Tascam ML-16D/ML-32D or older multi-track recorders like the Tascam DA-98HR or DA-78HR, for example. They can also be used with any other product fitted with D-sub connectors compatible with standard Tascam pin assignment according to AES59-2012.

The BO-32DE with its Euroblock inputs/outputs is primarily intended for fixed wiring in permanent installations, while BO-16DX/IN and BO-16DX/OUT with their standard XLR connectors are ideal when even more flexibility is required like in broadcast, recording or post production studios or during live events.

All three models feature rugged, 1U rack-mountable metal chassis with invertible and removable rackmount ears and lettering that can also be read when mounted upside-down.
