Extron ATB 220 – Amplifier Mounting Kit for Ceiling Tile Speakers

Product Overview

ATB 220, part number 70-1375-01. The Extron ATB 220 is an amplifier mounting bracket for ceiling speakers that secures a small plenum-rated power amplifier directly to an Extron ceiling tile speaker or mounting enclosure. It removes the need for a separate rack location or improvised above-ceiling support when amplification is distributed to the speaker itself. The one-piece galvanized steel bracket includes multiple mounting points to accommodate the supported Extron amplifier models, and ships with all required hardware. For integrators building distributed audio in conference rooms and open plan spaces, it keeps the amplifier captive, serviceable, and code-appropriate above the ceiling grid.

Product Description

Distributed ceiling audio frequently places a small amplifier near the loudspeaker rather than back at the rack, which shortens speaker runs and simplifies zone wiring. The ATB 220 amplifier mounting kit gives that amplifier a defined, mechanically sound home instead of leaving it resting on tile or tied to structure. It is a single formed piece of galvanized steel, so there is no assembly sequence to get wrong on a ladder, and the multiple mounting hole patterns let one part number serve the range of supported plenum-rated Extron amplifier models.

Because the bracket attaches to Extron ceiling tile speakers and their mounting enclosures, the amplifier travels with the speaker assembly as one unit. That matters at commissioning and again years later at service: a technician opening the ceiling finds the amplifier fixed in a known position rather than hunting through the plenum. All necessary hardware is included, so the install kit does not depend on whatever fasteners happen to be in the van.

Typical deployments are conference rooms, training rooms, and multi-purpose spaces where ceiling speakers are driven in small zones. The ATB 220 is an accessory rather than an electrical device, so it introduces no additional power, signal, or network requirements to the design. Specify one per amplifier location, and confirm your amplifier model appears on the Extron compatibility list before ordering.

Key Features

• One-piece steel construction — A single formed galvanized steel bracket means fewer parts to manage and a rigid mount once fastened.
• Multiple mounting patterns — Several hole positions accommodate the supported plenum-rated Extron amplifier models from one part number.
• Attaches to Extron ceiling speakers — The amplifier mounts directly to Extron ceiling tile speakers and mounting enclosures so the assembly stays together.
• Complete hardware included — All fasteners required for installation ship in the kit, so no site-supplied hardware is needed.
• Plenum-appropriate materials — Galvanized steel construction suits above-ceiling placement in plenum return spaces.
• Fast overhead installation — The bracket is designed for quick attachment from a ladder without in-place assembly.
