7.REAR PANEL FEATURES

7.1Inputs

The standard input panel of the FTX Series III amps is equipped with balanced 1/4" tip-ring-sleeve (TRS) phone jacks, balanced XLR jacks, and balanced screw- terminal inputs. The three types of connectors are inter- nally wired in parallel and may be used with balanced or unbalanced connections. The inputs are configured for pin 2 hot, meaning that a positive voltage applied to pin 2 will result in a positive output voltage across the speaker terminals. Pin 2 of the XLR jack is equivalent to the tip of the 1/4" TRS jack. An optional input transformer is available on all FTX and CFT amplifiers.

Balanced Inputs

It is recommended that balanced input connec- tions be used whenever possible to reduce ground-loop and environment-induced hum and noise. The (+) signal is on pin 2 of the XLR, and the tip of the phone jack. The (-) signal is on pin 3 of the XLR, and the ring of the phone jack.

Unbalanced Inputs

If an unbalanced input connection is used, then the (-) connection (XLR pin 3) should be connected to input ground ( XLR pin 1). If the 1/4" input jack is used unbalanced, the use of a mono (tip-sleeve) plug will au- tomatically tie the (-) connection to input ground. Never float pin 2 or pin 3 when using an unbalanced signal.
