T1 ToneMatch® Audio Engine / 1/4 inch Output Connections to L1® Family Members

Connecting from a T1 ToneMatch Audio Engine ¼ inch jack (Master or Aux) to other members of the L1® Family is simple. This article is applicable to L1 Compact, L1 Classic, L1 Model I or L1 Model II.

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.

OR

Classic or Model I

For full details see: T1 ToneMatch® Audio Engine / Power Stand Input Setting

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

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-Sleeve (unbalanced)

This should work fine.

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

This should also work, and provided better noise rejection over greater distances than the unbalanced connection above.

L1 Compact

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.

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.
