Bosch LBB 3422 Symmetrical Integrus Audio Input and 6-Channel Interpreter Module

The LBB 3422/20 Symmetrical Audio Input and Interpreters Module is used for interfacing the transmitter with the CCS 900 discussion systems and the LBB 3222/04 6-Channel Interpreter Desk with Loudspeaker. Different connections and switch settings are possible to also allow the module to be used with non-Bosch systems.

• Direct connection of up to 12 LBB 3222/04 Interpreter Desks for six languages
• Routing of floor signal (for instance from a CCS 900 discussion system) to interpreter desks
• Eight symmetrical inputs
• Facility for mounting input transformers for galvanic isolation between audio source and the transmitter

Controls and Indicators
• On-board switches can be set for directly connecting interpreter desks (LBB 3222/04) or other audio sources
• An on-board switch can be used to match the amplification of floor signals from CCS 900 or from other analogue conference systems
• An on-board switch can be used to replace the interpretation signal with the floor signal for distribution to the listeners when an interpreter channel is not in use

Interconnection
• Symmetrical analogue audio input; 25-pole female sub-D connector
• Audio and data bus connector; H 15 male connector
