EQ Switch — SW1
The EQ Switch (SW1) is used to insert the cable equalizer into the incoming AES/EBU signal. The
9252 can recover digital audio signals conforming to AES/EBU specifications and transmitted over
110ohm, coaxial cable, up to 600 metres (2000 ft) long without equalization. For cable lengths in
excess of 600 metres, we recommend that the input equalization be activated. Note that switching the
EQ in and out can cause audible artefacts.
• Pressing the EQ Switch SW1 will activate the yellow EQ LED to indicate this
feature is activated.
•
While the EQ Switch SW1 is activated pressing it again will disable the EQ and
the yellow EQ LED will go off.
