TL Audio 5051 - Manual (Page 8)

- Tip = Signal Phase (“+” or “hot”).
- Screen = Ground.
3.5 Instrument
Input.
Each channel has a 0.25” jack socket on the front panel (see Figure 2). A 2
pin (mono) jack plug is required, which should be wired as follows:
- Tip = Signal Phase (“+” or “hot”),
- Screen = Ground.
3.6 Sidechain Insert Point.
The sidechain insert point is provided on a 3 pin, 0.25” switched jack socket on
the rear of the unit. The pin connections are:
- Sleeve = Ground.
- Tip = Send.
- Ring = Return.
The insertion point is unbalanced, and operates at a nominal level of -2dBu. If
used as an additional send only (e.g. as a send to a tape machine or monitor
mixing desk), the Tip and Ring should be wired together, to preserve the
signal path through the insertion point. When used in this manner, the send
will be post-compressor. Please note that the sidechain insert is normally used
for frequency conscious compression only (see section 4.17) and doesn’t
break into the signal path in the same manner as a standard console insert
point. It doesn’t for instance allow you to insert an EQ “in-line” between the
5021 line input and compressor sections.
3.7 Balanced
Output.
The output is via a balanced, 3 pin male XLR connector. The mating connector
should be wired as follows:
- Pin 1 = Ground (screen).
