AUDIO CONNECTION
MICROPHONE INPUT:
With the modulator DIP switches set for microphone
input, the 3-pin XLR jack accepts balanced
microphones. Power for condenser microphones can be
selected by DIP switch. The minimum input level is
100uV and the maximum level is 90 mV.
XLR LINE-LEVEL INPUT:
With the modulator DIP switches set for line-level
input, the 3-pin XLR jack accepts balanced line-level
audio inputs. The minimum input level is 21mV and
the maximum level is 10uV.
1/4â TRS LINE-LEVEL INPUT:
The 1/4â Tip/Ring/Sleeve (TRS) jack can accept only
a balanced or unbalanced line-level input.
A 25 V, 70 V, or 100 V speaker line can be connected to the
balanced line input using an appropriate attenuator. âTâ
pads made with resistors yield better fidelity than speaker
matching transformers.
