AUDIO CONNECTION

Instrument Direct input & Parallel Link connection

As with all audio gear, always ensure audio system levels are turned down

or equipment turned off before making connections. This will avoid plug-

in or turn-on transients from damaging more sensitive components such as

tweeters.

There are 2 channels on the SDI-2, each featuring an XLR- ¼“TRS combo

jack INPUT, a TS ¼“ parallel LINK output and a balanced XLR OUTPUT.

Connect your source instrument or audio device to the input and the

balanced XLR output to the mixing console. The LINK connector output

provides the means for connecting the signal to an instrument amplifier or

personal monitor system. Unbalanced cables are much more susceptible to

noise than their balanced counterparts. Keeping unbalanced cables under

8 meters (25 feet) in length is good practice while balanced cables can

easily extend to 100 meters (300 feet). The balanced output of the SDI-2 is

mic level, meaning that it should be connected to the mic input of a mixing

console or mic preamp.

For Unbalanced connection, pin-3 should be connected to Ground with pin-1.
