miniDSP 4x10 HD is a versatile multi-channel Digital Signal Processor (DSP)
for analog and digital audio sources. Combining high quality audio algorithms along with a flexible graphical user interface, the 4x10 HD can be
used for multi-way speaker processing or multi-channel equalization. With its
balanced & un-balanced audio I/O, the platform easily fits the needs of most
audio systems. The sturdy powder coated steel enclosure, brushed aluminum
front panel and removable rack ears is a perfect match for both consumer
(Home AV) or commercial (ProAV) applications.
External control
 Front panel volume control
through rotary encoder
 I.R. remote control for Master
volume control and preset recall
On the processing side, the platform ranks high on versatility thanks to our
unique product concept of audio plug-ins. The unit is easily configured on
Mac/PC machines from a responsive and intuitive Graphic User Interface.
Once the unit is programmed, control of presets, master volume and digital
source selection can be done via the front panel encoder or Infrared (I.R) receiver without the use of a computer.
Software Control
 USB 2.0 interface
 Plug&Play - No driver required
 WinXP/Vista/7 & Mac compatible
 Firmware upgradeable for future
expansion
Power

Single external universal 12VDC
power supply
Applications
 Multi-way speaker processing
 Audio processor
 Mobile Audio
SYSTEM DIAGRAM
Finally, the miniDSP experience isn’t just another audio product. It’s about
joining the ranks of a large audio community with fully integrated tools and
extensive application notes. At miniDSP, we value partnerships and the complete integration of our products with well known platforms such as Room EQ
Wizard (REW) software is yet another step to provide fully integrated solutions
to our customers.
