S1 Pro system Line Out

Connection to Mixers

Connect the Line Out from an S1 Pro System to the input of another device.

If another device (like a third-party mixer or powered loudspeaker) has a 1/4 inch (6 mm) input, and you don't know if it's balanced or unbalanced, it's usually okay to use a Tip-Sleeve cable. If that connection is balanced, then a Tip-Ring-Sleeve cable is a better choice. If you don't know for sure and don't have time to test, use the Tip-Sleeve cable.

Most mixers will accept an unbalanced, line-level device. If you use a Tip-Sleeve cable from the S1 Pro system Line Out, you are providing an unbalanced, line-level signal.

Some mixers will accept a balanced line-level device. If you use a Tip-Ring-Sleeve cable from the S1 Pro system Line Out, then the connection is balanced.

Many modern powered loudspeakers will accept a balanced line-level device. If you use a Tip-Ring-Sleeve cable from the S1 Pro system Line Out, then the connection is balanced.

Connection to Powered Loudspeakers

To connect an S1 Pro System to another S1 Pro System please see: S1 Pro Daisy Chain Settings.

The same principles apply to connect to a third-party powered loudspeaker.

Connection to Passive Loudspeakers

The S1 Pro System Line Out will not drive a passive loudspeaker (one without an amplifier).

Recording

The S1 Pro Line Out is 1/4 inch (6.3 mm) Tip-Ring-Sleeve jack. That's balanced mono - NOT stereo. DO NOT USE a 1/4 inch (6.3 mm) Tip-Ring-Sleeve splitter like the one shown below. The 1/4 inch (6.3mm) Tip-Sleeve connections will have the polarity reversed and when you try to combine the signals later they may cancel each other.

If the recording device has separate balanced mono inputs, the connection is simple. [1]. Use a 1/4 inch (6.3 mm) Tip-Ring-Sleeve to 1/4 inch (6.3 mm) Tip-Ring-Sleeve cable and connect to ONE input. Pan the input up the middle and the signal will go to both left and right stereo busses.

If the recording device has a single stereo minijack input[2] you will need to convert to S1 Pro System balanced mono output to an unbalanced signal.

This will provide an unbalanced signal to the LEFT side of the stereo buss.

Do NOT use a cable like the one shown below. It will send the balanced mono output into a stereo input. The resulting signals (left and right) will have the polarity reversed. The two signals will cancel each other out.
