Suite 7.1 Installation Manual

Multi-pin 8 Channel Input Connection
The Suite 7.1 comes equipped with a multi-pin connector that accepts the output of a multi-channel
source component. DVD players that are capable of decoding high resolution MPL DVD Audio or
SACD can take advantage of the Suite 7.1’s multi-pin connector. The multi-channel connector follows
the industry listed in the chart below.
Required Input Cables
Depending on the multi-channel source component, you will need a multiple connector male RCA to
DB-25 or male to female DB-25 cable. Both of these cables are readily available from several cable
manufacturers. Contact ADA if you need assistance in locating an appropriate cable for the eight
channel multi-pin connector.
Connecting the Multi-pin Input Cable for a Multichannel Component
1. Plug one end of the multi-pin cable into the multi-channel component equipped with either a
DB-25 termination, RCA plug, or other connector. Be sure to follow the correct channel
identification based upon the chart below.
2. Plug the other end of this cable into the female DB-25 connector on the Suite 7.1.

Analog Audio Output Connections to Power Amplifiers
The Suite 7.1 is fully capable of decoding up to eight discrete channels of information. To fully take
advantage of the Suite 7.1’s decoding capabilities, you will need eight channels of amplification available
from ADA amplifiers such as the PTM-8150 or the PTM-8125. Of course, you can use four two-
channel amplifiers or other combinations tailored for each specific system. The analog output jacks are
identified on the rear of the Suite 7.1 by their reversed black background.
Required Input Cables
You will need one shielded interconnect cable terminated with RCA plugs on each for each of the
eight channels you will be using. While you will achieve best results by using all channels of the Suite
7.1, you can design systems using fewer channels if you wish. We recommend that you mark each of
the output cables to make it easier to identify each channel in case troubleshooting is necessary. If you
are using the ADA PTM-8150 with a display, we recommend the following configuration for an
optimum graphical representation.
IMPORTANT NOTE: Do not use “directional cables” when connecting components to the Suite 7.1.
These cables often leave the shield disconnected at one end, which can cause ground loops and
subsequent 60 Hz hum. Directional cables are usually labeled with arrows along the insulation to
identify which end to connect to the source.
