Digi-Wave ACM (Advanced Comms Module) Transceiver

DLT 400-ACM

The Digi-Wave Advanced Comms Module (ACM) Transceiver is the ultimate fully portable, two-way communication intercom solution for many different settings such as broadcast, theater, and live events. Digi-Wave ACM delivers all the core features production and event coordinator teams need—all call, flexible access point, subgroup division and custom naming, and flexible programming— at an affordable price. Backed by the reliability and long-lasting battery that Digi-Wave is known for, Digi-Wave digital intercom ACM provides a reliable, easy-to-use solution to 2 way comms.

Note: Existing Digi-Wave 400 DLTs, with firmware from January 2021 or later, can be updated with the Advanced Comms Module firmware. To upgrade your current DLT 400 to include the Advanced Comms Features, please contact Tech Services & Design.

The Digi-Wave Advanced Comms Module (ACM) Transceiver is the ultimate solution for portable intercom in small to medium broadcasts, theater productions, and live events. Offering up to 16 hours of battery life per charge, it supports uninterrupted, all-day use, making it the perfect choice for dynamic, fast-paced environments.

Enjoy unparalleled mobility and flexibility – Digi-Wave ACM is a fully portable, full-duplex wireless intercom solution. Its unique Flexible Access Point feature allows users to stay connected with their team without being tethered to a base station. This enables any centralized device within the system to act as the access point – maximizing the overall range of the system and enabling flexibility.

Easily initiate All-Call intercom from designated devices with a push of a button. This is great for stage managers, broadcast directors, and event coordinators to notify crew of things such as stage cues, the end of the commercial break, or emergency announcements. Need multiple people to initiate All-Call function? Digi-Wave ACM allows control units allow users to choose which units have all-call capability.

Designed with efficiency and ease of use in mind, the Digi-Wave ACM systems can be divided into up to 4 subgroups, allowing each team to have an individual communication line with just their team i.e. Lights, Camera, Stage, and Security. This setup allows leaders to effortlessly switch between subgroups for targeted communication. Great for large teams that need separate communication lines with smaller groups. Customize these subgroup names by using the prepopulated names or by using any 6-letter custom name.

Flexible programming allows settings to be adjusted online – or offline by designating a separate unit as a control unit. Administrators can conveniently program all system settings offline using the control function, making updates to the system without interrupting active communication.

*Existing Digi-Wave 400 DLTs, with firmware from January 2021 or later, can be updated with the Advanced Comms Module firmware. To upgrade your current DLT 400 to include the Advanced Comms Features, please contact TechBlue.

(1) DW ACC PAC4 – Charging Pack

Features

  • Fully Mobile, No Base Station. Digi-Wave ACM is a fully portable, full duplex, Two Way Communication System providing users complete flexibility to go where they are needed and remain in communication with their team.
  • Flexible Access Point. Unlike most wireless intercom devices in the market which use an access point to connect units, Digi-Wave ACM’s flexible access point (Main Sync feature) enables users to choose any device in the system to act as the digital access point maximizing the overall range of the connected system, and ensuring communication connectivity throughout the production area. Optionally, a unit can be mounted in a fixed location to maximize coverage.
  • All Call Function. This function enables one or several leaders to easily communicate with all subgroups.
  • Four (4) Subgroups. Creating subgroups enhances flexibility and easily ensures efficient communication management in diverse environments. Depending on the requirements, 2 – 4 subgroups can be created.
  • Customized Subgroup Naming. Admins can customize subgroups with up to 6 characters or choose from common subgroups like camera, audio, and stage. This customization helps team members quickly identify their subgroups and navigate communication more smoothly.
  • Quick, Seamless Subgroup Switching. One or several leaders can quickly switch between subgroups, ensuring seamless coordination and maximum efficiency.
  • Control Function. The new control function empowers administrators to program all system settings offline using a Digi-Wave ACM transmitter. This device enables convenient system updates, allowing administrators to easily manage communication settings.
  • Affordable Intercom. All of the core features production teams look for in a professional product intercom systems, plus the reliability and clear audio Digi-Wave is known for at a price that makes it accessible to small and mid-sized organizations.
  • All Day Battery Life. All-day use with up to 16 hours of run time on a single charge.
  • Private Line Functionality – Allow designated units to initiate private line communications with the lead unit.

How It Works

All Call – Activate All-Call function effortlessly from designated devices with just a press of a button. Activating all call mutes all other devices and allowing stage managers, broadcast directors, and event coordinators to announce stage cues, commercial break endings, or emergencies to all devices at once.
