Product details
The Dayton Audio MA1240a features a Class-AB output circuit that delivers superior audiophile sound quality and stable performance. Each of your installations zones can benefit from the MA1240as clean audio reproduction and exceptional functionality. The MA1240a can be stacked with other audio components and includes removable ears for mounting in standard audio racks (2RU).

Each of the twelve channels has its own dedicated input and independent level adjustment to provide further flexibility. By simply flipping a single switch, two channels can be bridged to increase the total power output for that zone. This is helpful when extra power is needed in certain areas.
The MA1240as manual, automatic on/off, or triggered 12V input turn-on modes facilitate easy integration into automated systems. For quick and easy troubleshooting of the system, each pair of channels or zones has a bi-color LED to indicate its operational status.

Dayton Audio stands for speaker excellence
Dayton Audio has been designing and manufacturing high-quality audio components for more than 20 years. The brand has made a name for innovation, high quality, and values. The products of this premium DIY audio brand are produced in North America, Europe, and Asia. Dayton Audio products have received acclaim worldwide throughout the years and are often compared favourably to similar items costing far more.
Dayton Audio woofers
The dominant component in a majority of loudspeaker designs, woofers are responsible for much of a system's tone and character. Don't underestimate this cornerstone element—Dayton Audio has the perfect woofer for every application and budget. Discover some of Dayton’s high-quality audio woofers, such as the popular Dayton Audio Ultimax UM18-22 from the powerful Ultimax Series, the Dayton Audio RSS390HF-4 featuring ultra-low distortion or check out the never-failing Dayton Audio PS95-8 full-range woofer.
Tweeters from Dayton Audio
Although they are the smallest driver in most loudspeakers, tweeters play an important role in our auditory information perception. Clarity, articulation, imaging—Dayton Audio tweeters make your speaker system come alive! Discover the immense popular Dayton Audio air motion tweeters and dome tweeters! Dayton Audio tweeters, such as the Dayton Audio AMTPRO-4, provide ultra-clean, detailed, and dynamic treble output.
Dayton Audio Drivers by Series

Dayton Audio Reference Series

The Dayton Audio Reference RS100-4 for example comes with a rigid yet lightweight anodized aluminium cone, enhanced motors with distortion-reducing devices, and carefully optimized T/S parameters result in accuracy and detail that are second to none.
Dayton Audio Designer Series
The Designer Series by Dayton Audio was developed specifically with the speaker designer in mind. It is an affordable, attractive line of drivers that puts performance first. Careful engineering ensures that the Dayton Audio DS135-8 5" Designer Series Woofer can handle full rated power at the lowest possible frequencies—without exceeding Xmax. The series combines useful performance parameters with elegant style.

Most low-frequency drivers smear, distort, or alter their input waveform. Ultimax DVC subwoofers by Dayton Audio, such as the Dayton Audio UM12-22 woofer, sweep a higher volume of air while preventing false, deceptive reproduction. They are designed to deliver powerful low-end response from modest-sized enclosures.
