using, the number of inputs available will vary.
There are 5 gain settings on each input as shown

levels are displayed on the PPM meters on the TLR303 2RU front panel, or on
the TLG3 GUI meters displayed on your PC. Rack Unit audio levels should be set
so that audio peaks average at the first set of orange PPM
LED
s. This represents
a program level of +4 dBu leaving the codec. Audio peaks can safely reach +21
dBu without clipping. We recommend that you adjust levels so that peaks don’t
16 dBu on both the rack unit and field unit codecs (the red LEDs on the
rack unit codec and the fourth solid bar on the field unit codec
LCD
).
For information in relation to setting levels on all

broadcast codecs, please
see the section in this manual titled PPM Displays.
