REAR PANEL FEATURES

9. Line Cord Socket and Fuse

Here is where you connect the detachable line cord that came in the box with your T•231. Plug the other end of the line cord into an AC outlet properly configured with the voltage required for your particular model (see AC Select Switch next).

The fuse is located behind the fuse cover, at the bottom of the IEC socket. See the “Troubleshooting” section on page 12 for information about replacing the fuse.

10. AC Select Switch

Set this switch to the correct voltage setting for the country you are in, 115 VAC or 230 VAC.

Note: The T•231 is shipped with the AC Select switch set to the 230 VAC position. If you are in a country that uses 100-120 VAC, remove the cover plate with a phillips-head screwdriver and set the switch to the 115 VAC position. A 315 mA fuse

is used for both voltages (115V/230V). See the

“Troubleshooting” section on page 12 for instructions on replacing the fuse.

11. GND LIFT Switch

When the switch is in the GND position, the audio ground is electrically connected to the chassis “safety” ground. Normally, this is how the switch is set.

However, occasionally a ground loop can be created in a system where the signal ground is connected to chassis ground, which can cause a hum or buzz to appear in the audio signal. If this is the case, try moving the switch to the LIFT position to eliminate the hum or buzz.

12. OUTPUTS

Three types of connectors are provided for the outputs — balanced male XLR and 1/4” TRS (Tip- Ring-Sleeve), and unbalanced RCA. These balanced outputs are in parallel, and provide exactly the same signal on all three outputs, regardless of which input jack is used. You can connect either a balanced TRS connector or an unbalanced TS connector to the 1/4” output jack.

13. INPUTS

Three types of connectors are provided for the inputs — balanced female XLR and 1/4” TRS (Tip-Ring- Sleeve), and unbalanced RCA. These inputs are in parallel, so do not connect more than one signal at a time to the input jacks for each channel. You can connect either a balanced or an unbalanced signal to the 1/4” input jack.

See “Appendix B: Connections” on page 14 for information on input and output connection wiring.
