TL Audio 5052 - Manual (Page 8)

- Pin 3 = Signal Non-Phase (“-” or “cold”).
Unbalanced inputs:
- Pin 1 = Ground (screen)
- Pin 2 = Signal Phase (“+” or “hot”).
- Pin 3 = Signal Ground.
3.3 Balanced Line Input.
The 5052 has a 3 pin XLR socket on the rear panel, which will accept both balanced
and unbalanced line level inputs. The mating connector should be appropriately
wired as follows:
Balanced inputs:
- Screen = Ground,
- Tip = Signal Phase (“+” or “hot”),
- Ring = Signal Non-Phase (“-” or “cold”).
Unbalanced inputs:
- Screen = Ground,
- Tip = Signal Phase (“+” or “hot”),
- Ring = Ground.
When using unbalanced signals, the signal ground may be obtained by linking pins 1
and 3 in the mating XLR connector. If this connection is not made, a loss in level may
result.
