Connect the CS650 to any of the A,B or C outputs on the rear of the HDDS Master
Control Module as shown below.
Internal Loudness Circuit
The CS650 includes an on board switchable Loudness Circuit with the switch located on
the right hand side of the Printed Circuit Board as shown in the picture above. When
the switch in the OUT position the CS650 response is flat, when the switch is in the IN
position a 6db increase in both Bass and Treble is applied. It is recommended to leave
this switch in the OUT position if the system includes separate subwoofers. This will
increase the maximum SPL capabilities of the CS650 by defeating the Bass boost that
occurs with the Loudness circuit IN. This Bass boost is not required when additional
subwoofers are used.
