Ashly TRA-4150 Power Amplifier

Power and Versatility: Ashly TRA-4150 Amplifier
The Ashly TRA-4150 stands as a testament to versatility and power, engineered to drive demanding live sound and fixed installation systems. Housed in a rugged 2-RU metal chassis, this 4-channel amplifier delivers 150W per channel at 4 Ohms, ensuring robust sound production. It's designed to handle both 4- and 8-ohm loads and is capable of managing transformer-coupled 70V and 100V lines simultaneously—a feature that significantly broadens its application range from concert halls to convention centers.

Efficient Design for High-Performance Environments
Equipped with a 2-stage high-efficiency switched-mode power supply and advanced Class-D amplifier circuitry, the TRA-4150 is built to provide a power-efficient solution without compromising output quality. Its ability to deliver 80 watts per channel at 8 ohms while maintaining a high power-to-weight ratio makes it an excellent choice for installations where space and power conservation are critical.

Tailored Control for Precision Audio Management
The TRA-4150's audio management capabilities are enhanced by a switchable high-pass filter and selectable gain sensitivity, allowing sound engineers to fine-tune audio to fit specific venue requirements. Turn-on delay DIP switches offer up to 8 seconds of delay, preventing the abrupt starts that can disrupt a user’s audio experience, while set-and-forget rear-mounted gain controls provide consistent sound levels.

Silent Operation in Sensitive Settings
Convection cooling ensures that the TRA-4150 operates quietly, making it ideal for environments where noise must be kept to a minimum, such as theaters and broadcast studios. This ultra-quiet operation does not sacrifice performance, allowing the amplifier to work at full capacity without the distracting fan noise typical of lesser models.

Comprehensive Protection for Long-Term Reliability
Ashly's commitment to durability is underscored by the TRA-4150's extensive protection circuitry. This includes safeguards against over-current, DC output, main supply rail over-voltage, and excessive temperature, ensuring the amplifier's longevity and reliability. Front-panel indicators provide immediate feedback on power status, standby condition, and signal presence, making monitoring straightforward.
