EDIROL by Roland MA-15D/Black Digital Stereo Micro Speaker Monitors by Roland

The MA-15D's offer a built-in Bass Enhancer. The Bass Enhancer operates on psychoacoustic principles that converts low frequencies into a series of over-tones which the human ear cannot distinguish from the original low frequencies. This allows the listener to perceive bass frequencies outside of the normal range of the speaker cone, without over-driving the woofer. With the Bass Enhancer the MA-15D's offer a strong low-end in a very compact set of reference speakers. In addition the MA-15D's offer a Sub-Out port, to connect a sub for isolating very low frequencies. It offers conveniently placed Volume and Tone controls. Adjust the volume and tone directly from the front of the speaker. While a large studio setup typically uses a mixer to control Output level to the speakers, compact Desktop setups can rarely afford the space a mixer requires. This is no issue with the MA-15D's. You can adjust your output Volume and Tone right on the front of the speaker. You can also connect two different sources directly into the MA-15D's, allowing you to listen to Audio from any two line-level sources. For example, you can have both your Computer and your Stereo connected to the MA-15D's. The MA-15D's offer independent volume control for each of these inputs, effectively taking the place of a small desktop mixer for monitoring. You can also plug Headphones directly into the MA-15D's and mix without disturbing other people.
