The TASCAM BO-32DE is a passive 32-channel analogue breakout box designed to convert balanced audio connections between Euroblock terminals and 25-pin D-sub connectors.

It is primarily intended for permanent commercial installations using equipment such as the TASCAM ML-16D and ML-32D analogue-to-Dante converters. It can also be used with other professional audio equipment that follows the TASCAM D-sub pin assignment specified by AES59-2012.

Key Features

• 32 balanced analogue audio channels
• 16 two-channel Euroblock connector positions
• 32 individual Euroblock plugs included
• Four female 25-pin D-sub connectors
• Eight audio channels per D-sub connector
• Each eight-channel group can operate as inputs or outputs
• AES59-2012-compliant TASCAM D-sub pin assignment
• Passive operation with no power supply required
• Rugged metal construction
• Removable and reversible rack ears
• Supports front-facing or rear-facing rack installation
• Standard 19-inch, 1U rackmount design
• Can also be used on a tabletop with the rack ears removed
• Space provided for connection and signal-routing labels
• D-sub cables are not included

Channel Configuration

Total audio channels:

• 32 balanced analogue channels

Channel groups:

• Channels 1–8
• Channels 9–16
• Channels 17–24
• Channels 25–32

Each group of eight channels can be assigned independently as an input or output group. For example, the BO-32DE can be configured with 16 input channels and 16 output channels, or with 24 inputs and eight outputs.

Front-Panel Connections

• Connector type: Balanced Euroblock
• Connector pitch: 3.81 mm
• Connector positions: 16
• Total audio channels: 32
• Wiring per channel: Hot, cold and ground

The package includes 32 removable three-pole Euroblock plugs with strain-relief tabs and cable bands.

Rear-Panel Connections

• Connector type: Female 25-pin D-sub
• Number of connectors: Four
• Channels per connector: Eight
• Total channels: 32
• Attachment screws: Eight No. 4-40 UNC screws

The D-sub connectors follow the standard TASCAM balanced analogue pin assignment compliant with AES59-2012.

Compatible Equipment

The BO-32DE is designed for use with:

• TASCAM ML-16D
• TASCAM ML-32D
• Compatible TASCAM multitrack recorders
• Professional audio equipment with compatible 25-pin D-sub connections
• Equipment following the AES59-2012 TASCAM pin assignment

Compatibility should be confirmed before connecting equipment from another manufacturer because not every DB25 audio connector uses the same pin configuration.

Passive Operation

The BO-32DE is a passive connection adapter and does not require mains power, batteries or an external power adapter.

It does not provide:

• Microphone preamplification
• Phantom power
• Analogue-to-digital conversion
• Dante conversion
• Signal amplification
• Mixing
• DSP processing
• Level adjustment
