The class AB design of the MA1240a ensures outstanding sound quality and stable performance. Each channel comes with independent volume control, offering personalized audio settings for different areas. Additionally, the amplifier features bridgeable outputs for added power, silent temperature-controlled cooling fans, and low standby power consumption.
While sharing its design with the more powerful Dayton Audio MA1260a, the MA1240a uses class AB technology to provide better distortion performance. The combination of a linear power supply with heavy-duty transformers and class AB technology results in excellent sound quality and stable performance.
The input and output interface of the MA1240a offers extensive flexibility in connecting source equipment and speakers. Each zone uses two channels that can be set for individual or bridged output, with access to three inputs per channel: one individual input and two bus inputs. The bus inputs are capable of delivering a single signal to all channels simultaneously. This is complemented by a trigger input and output, as well as a bus output for easy integration of multiple devices.
Designed with solid rubber feet for standalone applications and removable brackets for 19” rack mounting, the MA1240a is built to fit into any audio setup, whether in a home, studio, or commercial environment.
The amplifier offers manual, automatic, or 12V triggered turn-on modes for seamless integration into automated systems. Each pair of channels or zones features a bi-color LED for quick and easy system troubleshooting, indicating operational status at a glance. For connections, use 14-18 AWG stranded two-conductor loudspeaker wire with Phoenix-style connectors.
Yes, the MA1240a is compatible with line signals from various music streamers, allowing you to connect different or multiple streaming devices to separate zones. For DIY enthusiasts, explore the possibilities with Arylic products to create your own multi-zone streaming setup.
