AXW-AVT Internal Jumper Settings:

The AXW-AVT has three internal jumper settings to control the functionality and conditioning of the audio circuitry. These should be adjusted as necessary, based on the selection of fiber / Ethernet equipment used. To access these jumpers, the chassis of the AXW-AVT will need to be opened. Adjusting these jumper settings will NOT invalidate the AXW-AVT’s warranty.

Transmitting Gain (CN3):	Controls the amount of amplification applied to the outgoing audio (‘Audio Out’)
	connection of the AXW-AVT. A ‘Low’ setting provides no gain, whereas a ‘Hi’
	setting applies approximately +10db of amplification. Default position is ‘Low.’
Receive Gain (CN4):	Controls the amount of amplification applied to the incoming audio (‘Audio In’)
	connection of the AXW-AVT. A ‘Low’ setting provides no gain, whereas a ‘Hi’
	setting applies approximately +10db of amplification. Default position is ‘Low.’
Muting Circuit (CN5):	The ‘Muting Circuit’ controls whether audio to/from the door station is
	completely full-duplex, or limited to one direction or the other (semi-duplex).
	This adjustment is required in situations where latency may be present between
	audio transmission and reception (i.e., Ethernet). In such situations, the muting
	circuit should be set to ‘On’ to reduce audible echoing. In situations where
	latency is not an issue (i.e., fiber, direct connections, etc.), this should be left in
	the default ‘Off’ position.
