Fig 12. Balanced to Unbalanced Cables

When connecting the 1/4" unbalanced (TS) inputs and outputs of the

Model SSM to balanced equipment, it will be necessary to configure

your cables in order to unbalance the signal.

There are 2 types of balanced output circuits; transformer and

transformerless (electronically balanced). Balanced audio outputs are

normally terminated with 3 pin XL type connectors, 1/4" TRS (stereo)

type jacks, or on rare occasions, with screw terminals.

When connecting the unbalanced (TS) input of the Model SSM to a

transformer output, it will be necessary to connect the low (-) signal to

the ground conductor; pin 3 to pin 1 of the XL, or the ring to the sleeve

of a TRS plug. When connecting to a transformerless output, it is

standard practice to connect to the high (+) output only and not connect

the low (-) signal to ground. Check the manual of each piece of audio

equipment for specific details.

Due to the lack of standards for XL connectors, some equipment may

use pin 3 of the XL for the high signal. For this configuration, connect

pin 2 to pin 1 on the XL, and connect the high to pin 3.

There are 2 types of balanced input circuits; transformer and

transformerless (electronically balanced). Balanced audio inputs are

normally terminated with 3 pin XL type connectors, 1/4" TRS (stereo)

type jacks, or on rare occasions, with screw terminals.

When connecting the unbalanced (TS) output of the Model SSM to a

balanced input it is almost always necessary to connect the low (-) input

to the ground conductor; pin 3 to pin 1 for XL, or the ring to the sleeve

of a TRS plug.

Due to the lack of standards for XL connectors, some equipment may

use pin 3 of the XL for the high signal. For this configuration, connect

pin 2 to pin 1 on the XL, and connect the high to pin 3.

Figure 12 below shows the recommended method of connecting the

Model SSM's unbalanced jack to a balanced device.
