Main Features
● In Pursuit of High Sound Quality
The DS-50A powered monitor uses a two-way, bi-amplifier design to
achieve high sound quality.
The monitor features a 120-mm LF Driver and a 19-mm soft-dome HF
Driver as speakers. The amplification includes 30-watt and 20-watt
amplifiers designed to achieve high sound quality.
● Digital Input
In addition to XLR and TRS phone analog input, the DS-50A is provided with digital input connectors
(coaxial and optical) that support 96 kHz sample rate and 24-bit digital audio.
Digitally input signals are reproduced faithfully through 24-bit D/A conversion, thus preventing noise
or a drop in sound quality.
You can use the monitors with a wide variety of equipment and applications through selective use of
the analog and digital settings.
● Reproduction of a Variety of Speaker Sounds
(combination with the VS or VM)
By connecting the Roland V-Studio (VS series) or V-Mixer (VM series) to the DS-50A and using
Speaker Modeling Function of VS or VM, the DS-50A can reproduce the
sounds from a wide range of speakers, ranging from the professional
monitors from other manufacturers to the speaker in a small household
television set.
You can use the DS-50A in combination with the V-Studio or V-Mixer to
simulate the sound checks at mixdown, which conventionally have required
switching between multiple pairs of monitors set up to compare the sound.
* Please be aware that not all VS/VM series units are capable of providing
speaker modeling. Before making your purchase, you should confirm that
the unit you are considering does indeed provide the features you desire.
