Connecting the X-NRI to the Sound Source Equipment
There are 4 auxiliary audio source input interfaces (RCA ports) and 4 balance input interfaces for
the X-NRI. Auxiliary audio source input interfaces are able to connect to external audio devices
directly. The operation is the same as the operation on the DCS. The polarity of signal cable, such
as hot end "H", cool end "C" and grounding end "G" should comply with the input audio device
when connecting balance input interface with external audio source.
Connecting the DCS to the DA
Two signal cables need to be used when connecting DCS and amplifier. Twisted pair cables are
used to connect the audio output interface of DCS and audio input interface of amplifier. 1070V
output interface of amplifier should connect to 1070V input interface of DCS.
There are 2 rows of interfaces of audio output interface (control interface) on DCS. Lower
interfaces include 2 audio signals, and upper interfaces include 1 audio signal. The upper
interfaces correspond to the even channel of lower interfaces. For example, if the lower channels
are 1 and 2, the upper channel should be 2.
Note:
The DCS can be connected to the power amplifier in the following configurations:
Connect the PA1/2 and PA2 port of the single-channel power amplifier to the DCS control port
•
using two twisted-pair cables, as shown in Figure 1
Connect the PA1/2 port of the two-channel power amplifier to the DCS control port using one
•
network cable. Refer to Figure 2.
Connect the PA1/2 and PA3/4 port of the four-channel power amplifier to the DCS control port
•
using two network cables, as shown in Figure 3.
The steps for connecting DCS to the amplifier are as below:
1. Connect the control port of the amplifier
Connect the DA RJ45 port to the DCS control port using the audio input lines that are included
in the package containing the DA, as shown in Figure 10.
