Overview
The Digital Acoustics IP7-FX is a versatile IP (Internet Protocol) 2-way audio
module with an integrated 8-watt amplifier, call button, relay, sensor and 2port network switch. It is designed to replace the older IP7-ST/STx1, IP7SS8, IP7-SE8 and the IP7-FD model IP audio modules and can support:
• Full duplex audio with echo cancellation
• Half duplex audio using a separate mic and speaker
• Half duplex audio using the speaker as both a speaker and microphone
• Paging only audio using one or more 8 Ohm speakers
• Paging only audio using an analog amplifier which is connected to
multiple speakers
With this flexible design the IP7-FX can be used in a variety of applications
where network-based audio is required.
Standard features of the IP7-FX include:
• Pluggable DIN connectors to facilitate wiring
connections
• Flexible analog audio device options
• Highly scalable, seamless expansion
• Mounting via rail or surface mount
• Fixed or DHCP compliant IP assignment
• Powered via external 12VDC or PoE (802.3af)
• Integrated 2-port switch
• Field upgradeable firmware
The IP7-FX must be configured using the TalkMaster software or
eSIP software before being used. Please consult the configuration
section of the software manual for details.

The IP7-FX does not support the Aiphone IE/IF Series two wire Door Station. The
IP7-STx is the only Digital Acoustics IP audio module that supports the IE/IF Series

ST MIC switch
The ST MIC switch is in the MIC
position by default. If using single
transducer mode (speaker used as both
a speaker and microphone) use a small
screwdriver to move the recessed
switch to the ST position (towards the
DIN clip).
