Front and Rear Panel Features

Rear Panel

1.XLR INPUT: This jack accepts XLR input connections with either balanced or unbalanced wiring. The input wiring of an XLR connector should be as follows:

XLR PIN 1	Signal ground	(Shield)
XLR PIN 2	Signal positive	(+)
XLR PIN 3	Signal negative (–)

2.TRS INPUT: This jack accepts 1/4” connections with either balanced or unbalanced wiring. For balanced wiring, a three-conductor TRS plug is necessary. The input wiring of a TRS connector should be as follows:

TRS TIP	Signal positive	(+)
TRS RING	Signal negative (–)
TRS SLEEVE	Signal ground	(Shield)

Unbalanced 1/4” wiring can be done with either a two- or three-conductor (TS or TRS) plug. A two-conductor (TS) plug automatically grounds the signal negative input, whereas a three-conductor (TRS) plug, wired unbalanced, provides the option of leaving the negative input open or grounded. We recommend that you ground the unused negative input (this can be done by wiring the ring and sleeve of the TRS plug together).
