Listen Technologies C10-2D – 10A MultiLoop Hearing Loop Driver

Product Overview

The Listen Technologies C10-2D is a 10A hearing loop driver from the Ampetronic C-Series, specified for permanent installation in commercial AV systems where assistive listening is an accessibility requirement. It drives a phased array MultiLoop design and accepts Dante network audio input, so it fits the signal architecture already chosen for the room. The Dante input lets the driver take program audio straight off the audio network alongside the room DSP and conference system. The unit is a compact 1U rack mount chassis with an internal power supply, which keeps a commercial hearing loop system inside the existing AV rack.

Product Description

The C10-2D sits in the Ampetronic C-Series range that Listen Technologies distributes. The line is built so performance characteristics stay consistent from entry-level rooms up to flagship installations, which matters when a specification has to cover several rooms of different sizes in the same building.

A MultiLoop driver runs a phased array rather than a single boundary loop. That is the design used when overspill into an adjacent space has to be controlled, when the room has significant metal in the structure, or when even field strength across a large floor area cannot be achieved with a single perimeter run. The 10A output delivers 33.9VRMS drive voltage. Because the audio input arrives over Dante and the unit is AES67 compliant, the driver subscribes to a network channel like any other endpoint, keeping the assistive listening feed under the same routing and level management as the rest of the room.

Installation is 1U of rack space, or wall mounting using the separately ordered WM-C-HP wall mount kit for C-Series 10A and 14A drivers. Loop conductor and terminations are ordered separately: 14 AWG hearing loop cable for perimeter runs, foil-to-cable crimp lugs where copper foil tape meets cable, and PVC protective extrusion where the loop is surface run and needs protecting.

Hearing loop performance is verified by measuring magnetic field strength against IEC 60118-4, not by a listening check, so plan the commissioning step at design stage. Most integrators pair the driver with a field strength meter and its signal connection cables. Where the building structure contains significant steel, a metal loss test driver is used during survey to quantify the loss before the driver rating is fixed.

Key Features

• 10A output stage — Delivers 33.9VRMS drive voltage for phased array MultiLoop design designs sized during loop survey.
• MultiLoop phased array output — Controls overspill into adjacent spaces and evens field strength across large floor areas.
• Dante and AES67 input — Takes program audio directly from the audio network without a dedicated analog feed.
• Switchable 250Hz low cut filter — Removes low frequency content that consumes headroom without improving speech intelligibility.
• 1U rack mount with internal power supply — Installs in the AV rack without an external supply or additional rack space.
• IEC 62489-1 designed — Built to the loop driver performance standard, supporting IEC 60118-4 compliance when correctly installed.
• Consistent C-Series behaviour — Shares performance characteristics across the range, so a specification carries between rooms of different sizes.

Typical Applications

• Conference room
• Boardroom
• Auditorium
• House of worship
• Government space
• Training room
• Multi-purpose room
• Commercial meeting space

Technical Specifications

Specifications sourced from the Ampetronic C-Series datasheet (UP39802-7). Confirm loop area and current requirements against a site survey before specifying.

Frequently Asked Questions

How do I know the 10A rating is right for my room?
Current rating follows the loop design, not the room dimensions alone. Loop area, aspect ratio and the metal loss measured during survey together determine the drive current required. Confirm the design before fixing the driver model; a metal loss test driver is used on site where the structure contains significant steel.

Does this model need a separate analog audio feed?
No. This variant accepts Dante network audio and is AES67 compliant, so it can be fed from the same audio network as the room DSP. Non-Dante and networked variants are available where a Dante input is not required.

Can it be installed outside a rack?
Yes. The WM-C-HP wall mount kit for C-Series 10A and 14A drivers covers this chassis for installations without rack space, such as equipment closets and AV cupboards.

What does the installation need beyond the driver?
Loop conductor, terminations, and commissioning equipment. Perimeter runs typically use 14 AWG hearing loop cable, with crimp lugs where copper foil tape meets cable and protective extrusion where the loop is surface run. A field strength meter is required to verify and certify the installed system.

How is the installation certified?
Hearing loop performance is measured against IEC 60118-4 using a field strength meter. A subjective listening check is not sufficient and will not satisfy an accessibility consultant. Budget the measurement step into the commissioning schedule.

Does a MultiLoop driver replace two perimeter drivers?
No. MultiLoop drives a phased array as a single coordinated system rather than two independent loops. It is specified where overspill has to be controlled or field strength evened across a large area.

What warranty and support apply?
