The DLT 400-AIM is a portable, professional digital interpretation transceiver designed for effortless multilingual communication. Equipped with the Digi-Wave Advanced Interpretation Module (AIM), it supports 24 channels, the highest among comparable systems, and provides crystal-clear digital audio across multiple speakers and listeners.
Interpretation is simplified with the Q&A mode, allowing interpreters to switch between two languages during panel discussions or live Q&A sessions, while supporting multiple active microphones per language. The system also enables administrators to customize channel names to up to 5 characters, select from 100 ISO language codes, organize subgroups, and manage programming offline using the control function. Every system includes at least one DLT 400-AIM two-way transceiver and is compatible with existing Digi-Wave 400 receivers running firmware 1.3.0 or higher.
This versatile transceiver is ideal for government courtrooms, corporate training sessions, guided tours, healthcare facilities, and educational settings, providing reliable, interference-free performance with a frequency-hopping algorithm to maintain consistent, high-quality digital audio.
