Page 7: Product Overview
The C-DSP 6x8 typically connects to a head unit with four output channels, and directly drives power amplifiers for multiple loudspeakers or drivers. Because of its flexible internal routing, the C-DSP 6x8 can be used in a variety of situations involving a mix of passive speakers, active speakers, and subwoofers. -
Page 8: The Minidsp Concept
1.2 T HE MINI CONCEPT The miniDSP concept is “one hardware unit + one software plugin = audio processing solution.” This concept leverages the inherent flexibility of DSP (digital signal processing) to deliver a range of flexible but cost-effective solutions. -
Page 9: The Minidsp Workflow
6. Make audio connections With the initial configuration done and now that you are familiar with the various controls, it’s time to connect the miniDSP C-DSP 6x8 into your system. Ensure that all power is turned off when making audio connections. See Hardware connectivity on page 13. - Page 10 Power on your connected equipment, first on the input side (e.g. head unit), then on the output side (e.g. power amps). Turn the volume on your C-DSP 6x8 down low (view the Master Volume display in the plugin while turning the knob counter-clockwise) and start playing music or a pink noise test signal.

To install the miniDSP software, open the Mac folder of the download, and double-click on the C-DSP-6x8.dmg file to open it in a new window. Then double-click on the installer program, Install-C-DSP 6x8.app. Once installation is complete, the C-DSP 6x8 plugin will automatically start. -
Page 13: Hardware Connectivity
3.2 H ARDWARE CONNECTIVITY Connections to the C-DSP 6x8 are made on the front and rear panels. 3.2.1 Analog inputs There are four analog output channels. Unbalanced connections can be made directly to the RCA jacks on the front panel. Be sure to take careful note of the channel numbering shown in this diagram and on the front panel. -
Page 14: Digital Input
There are eight analog output channels. Unbalanced connections are made from the RCA jacks on the rear panel to the power amplifiers. Be sure to take careful note of the channel numbering shown in this diagram and on the rear panel. miniDSP Ltd, Hong Kong / www.minidsp.com / Features and specifications subject to change without prior notice... -
Page 15: Dc Power
3.2.4 DC power The C-DSP 6x8 incorporates an isolated DC power convertor and is designed for direct connection to the vehicle's power supply (nominally 12V). Power is connected via the four-way terminal block: The terminal block also provides two pins for remotely switching power on and off. To enable the remote enable, a jumper inside the unit needs to be moved. -
Page 16: Remote
The wire remote can be positioned anywhere in the vehicle and is connected via the supplied cable. The RJ11 plugs on each end simply plug into the base of the remote and into the rear panel of the C-DSP 6x8. The wired remote also contains the receiver for infrared remote control. -
