Finally, note that the miniDSP audio processor is a very flexible device, and many of the questions we receive at the tech support department are already answered in this user manual and in the online application notes the miniDSP.com website. So please take the time to carefully read this user manual and the online technical support. -
Page 7: Product Overview
RODUCT VERVIEW Thank you for choosing the miniDSP 10x10 Hd audio processor or 8x8 Kit board. The miniDSP 10x10 Hd and 8x8 Kit board are a powerful and flexible multichannel digital audio processor that is ideal for applications such as home theater and surround-sound monitoring. -
Page 8: The Minidsp Concept
HOOSING THE RIGHT MINI The miniDSP 10x10 Hd is a self-contained “miniDSP in a box”. It has eight analog input channels and eight analog output channels, as well as two digital input and output channels with AES/EBU, S/PDIF, and TOSLINK connectors. -
Page 9: Choosing A Plugin
HOOSING A PLUGIN The plugin that is usually used with the 10x10 Hd and the 8x8 Kit is the 8x8 plugin, which runs at 48 kHz sample rate. It is also possible to run the 2x8 plugin, which runs at 96 kHz. The table below summarizes the key... -
Page 10: The Minidsp Workflow
With the initial configuration done and now that you are familiar with the various controls, it’s time to connect the miniDSP 10x10 Hd or 8x8 Kit into your system. Ensure that all power is turned off when making audio connections. See Hardware connectivity on page 14. - Page 11 10. Continue to operate offline With your miniDSP processor configured, you can continue to operate in offline mode—that is, without the computer connected. To do so, simply disconnect the USB cable. The processor “remembers” the configuration last set, and will continue to operate without the computer.

Page 14: Hardware Connectivity
3.2 H ARDWARE CONNECTIVITY All connections to the 10x10 Hd are made on the rear panel. For the 8x8 Kit board, also see documentation. 3.2.1 Analog input and output There are eight analog input channels and eight analog output channels, available in both unbalanced and balanced connections. -
Page 15: Digital Input And Output
Fit the supplied IEC cable to the 12 VDC power supply. Plug the DC connector into the +12VDC socket on the rear panel of the 10x10 Hd, then plug the AC mains plug into the power outlet. Apply power to the processor only after all analog input and output connections have been made. The processor can usually be left powered on. -
Page 16: Usb
3.3 G AIN STRUCTURE The miniDSP audio processor provides a great deal of flexibility in matching with other equipment. In addition to providing balanced and unbalanced inputs and outputs, input sensitivity and output gain can be selected to adapt to different equipment. The maximum input and output signal levels are shown in Table 1. -
Page 17: To Change Input Sensitivity
A set of eight DIP switches located on the main circuit board select the output gain of each channel. Remove the top panel of the 10x10 Hd to access these jumpers. The switches can be set independently for each channel, and affect output gain for both the balanced and unbalanced output connections to that channel. -
