Overview

You can use TS (Tip-Sleeve) unbalanced cables, OR TRS (Tip-Ring-Sleeve) balanced cables. If the cable uses ¼ inch jack plugs and the ends are the same, then the cable should be fine.

This should work fine.

¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)

Since the ¼ inch phone connections at the Bose Classic and Model I Power Stand are unbalanced there is no particular benefit using balanced cables but there is no harm.

L1 Model II


¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)

A balanced connection is preferred and will provide better noise rejection over greater distances than the unbalanced connection.

Tip-Ring-Sleeve to Tip-Ring-Sleeve

¼ Inch Tip-Ring-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)

This should work fine but a balanced connection (immediately above) is preferred especially if you will have cable runs in excess of 20 feet (6 meters) or if you hear line noise, hum or hiss.

Using a Bose device as the source

When connecting a ToneMatch Mixer[1] or an S1 Pro System Line Out to an S1 Pro System channel 1 or channel 2

Set the volume control to 10:00 o'clock

The signal strength from a ToneMatch Mixer[1] or an S1 Pro System Line Out is sufficient to achieve the maximum usable volume from the S1 Pro System
Control the overall volume from the ToneMatch Mixer[1] or the first S1 Pro System

Using a third-party source (not a Bose device as the source)

For each channel you are using on the S1 Pro System

  1. Turn the channel volume off
  2. Connect your sound source
  3. Adjust the volume of the source device output to the reference or nominal output level.
    • On analog consoles this may be marked as unity or 0 dB.
    • On digital consoles this may be marked as -18 dBFS[2][3]. The exact value (-18 dBFS to -20 dBFS) may vary depending your location[4].
    • Refer to the manual for the source device for details.
    • If the source device does not have metering or indicators, set the output as high as you can without hearing distortion or seeing red indicator lights.
  4. While playing/singing as loud as you will during your performance, bring up the channel volume until you see solid green on the channel indicator light. Occasional flickers of red are okay. If you see solid red or you hear distortion, turn down the volume.

A balanced connection is preferred and will provide better noise rejection over greater distances than the unbalanced connection.
