Connections
The MM-8802 includes several different connection types. First and foremost is the connection to the MediaMatrix processing
product that you will be using for your system. The following illustrations show the various connections to MediaMatrix prod-
ucts and their cable types. Also, please refer to the section on CAT 5 cables on pages 38-39. There are two options for connect-
ing the digital audio interface on the MM-8802. Which option you use depends on what MediaMatrix DPU product you are
using. This configuration requires the MM DSP or MM DSP-RJ DPU card within the MediaMatrix system.
The first example shows typical connections when using MediaMatrix frame-based systems. Using the MM-8802 with the
MM DSP-RJ provides the maximum performance and I/O efficiency. With this configuration, cable lengths of 50 feet are possi-
ble between the DPU card and the MM-8802. This configuration uses two CAT 5 cables (not included) for each MM-8802.
The design of the MM-8802 and the MM DSP-RJ DPU card includes separate conductors for transmit (TX) and receive (RX)
audio data.
The MM DSP DPU card is the original MediaMatrix audio processing card, also known as the "legacy" DPU card. The MM
DSP uses a proprietary 9-pin DB-9 connector for the digital audio interface with MM-8800 Series break-out-boxes. This cus-
tom cable, available only from Peavey, is designed to carry the high speed data between the MM DSP and MM-8800 Series
Break-out-Boxes in a single cable. Both TX and RX conductors are housed in the same cable. It is very important to note that
this cable has a distance limit of six feet. Under no circumstances can this distance be exceeded. The MM DSP DPU card will
not perform to specifications without the factory supplied cable.

Using the X-Frame
™
88 with the MM-8802 affords the same type of interconnect as the MM DSP-RJ DPU card. Although the
X-Frame 88 is a stand alone product, it provides connectivity for two MM-8802 break out boxes, extending its total I/O to
24x24. As with the MM DSP-RJ, the X-Frame 88 uses two CAT 5 cables, one for TX, one for RX for each MM-8802. For more
information on these configurations, please refer to the X-Frame 88 User Manual.
