EQ Switch — SW1
The EQ Switch ( SW1 ) is used to insert the cable equalizer into the incoming AES/EBU signal. The 9262 can
recover digital audio signals conforming to AES/EBU specifications and transmitted over 75ohm, 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.
