Model 408 8 Port Bridge

ComLabs' Model 408 8 Port Bridge

The Model 408 is a good choice for customers that are looking for a cost effective way to add additional terminals at their location. With the Model 408, users can connect 7 additional terminals to their existing audio network. If more capacity is needed, another bridge can be “daisy-chained” to the existing bridge that is full.

 

NEW FEATURE #1 - LINE POWERED DISTRIBUTION

If you need to power up each of your phone terminals through the LINE cord, there is a single jack on the back panel to apply 24VDC, which in-turn gets routed to pins 2 & 7 of each of the four ports.

 

NEW FEATURE #2 - Port 1 – RX level adjustment, Port 2 – TX level adjustment

Port One input RX can be boosted by 20 dB and Port Two TX output can be reduced by 20 dB.
