WIRING THE MATRIX DIRECTLY TO A
4-WIRE AUDIO DEVICE
An external 4-wire audio device can be directly connected to a port
connector through the four audio pins, as shown in Figure 4-11. If there
is excessive noise on the lines between this device and the matrix, the
device may be electronically unbalanced with the rest of the system.
The device will need to be isolated with external isolation transformers.
The “CALL SEND” output can be connected to the “CALL REC” input
to tell the system software that this is a directly connected port.
The Eclipse Configuration System allows the changing of the audio
output reference level between -24, -21, -18, -15, -12, -9, -6, -3, 0, +3,
+6, +9, +12, +14 dB. With a +12dB output reference level, it is possible
to drive a 200 to 400 Ohm headset directly with a port output for such
uses as direct IFB feed.
The Eclipse Configuration System allows the changing of the audio
input reference level between -12, -9, -6, -3, 0, +3, +6, +9, +11 dB.
