Roland DS-90A Specification

The Roland DS-90A Amplifier is a precision-engineered active reference monitor designed for professional audio applications. It features a bi-amplified system delivering a total power output of 120 watts, with 60 watts dedicated to the low-frequency driver and 30 watts to the high-frequency driver, ensuring clear and accurate sound reproduction across the frequency spectrum. The monitor incorporates a 24-bit/96kHz digital input, facilitating high-resolution audio playback, and is equipped with a 1-inch soft-dome tweeter and an 8-inch polypropylene cone woofer, both driven by high-efficiency amplifiers for optimal sound clarity and detail.

The DS-90A's frequency response ranges from 42Hz to 20kHz, providing a broad and balanced audio landscape suitable for various mixing and mastering tasks. The cabinet is constructed from high-density MDF with a bass-reflex design, enhancing low-frequency performance and reducing unwanted resonances. It includes XLR and 1/4-inch TRS balanced inputs, offering versatile connectivity options for integration into different studio setups. The monitor also features user-adjustable controls for high-frequency and low-frequency EQ, enabling precise tuning to match the acoustic characteristics of the listening environment.

Additionally, the DS-90A is designed with a compact form factor, measuring approximately 11.8 x 15.9 x 12.4 inches and weighing around 32 pounds, making it suitable for both small and medium-sized studio spaces. Its robust build and sleek design ensure durability and aesthetic appeal, while its advanced electronics and acoustic performance make it an ideal choice for professional audio engineers seeking reliable and high-quality sound monitoring solutions.
