signal. Leave at Unity to start, boost as needed.
2. Output Level – Attenuates the RCA signal output.
3. Inputs – Connect these RCAs to your audio source.
4. Output – Connect these RCAs to your amplifier or signal processor .
5. Balanced Input / Output – Connect your RJ-45 & Cat5/6 cable here. It
should be wired in the T-568B configuration .
6. A / B – This switch sets the configuration of the Ethernet pins in the
Balanced Input / Output (Ethernet) jack. If the first unit is set to A, then set
the other unit to B in order to send and receive audio signals.
7. Ground / Lift (shielded Cat5/6 only) – The default Ground setting
should be good. If you get a ground loop/ AC hum noise though, you
can push this switch in on one side or the other to create a “drain” wire
set up. Try either side then both to correct for the noise.
8. 24 VAC / 300mA – Connect the Power adapter here, conveniently
labeled in
technicalese.
9. Power – When the Power LED is lit, the BLX-1K is on; when not lit it’s off.
