2-13. Equivalent input Noise
An input terminal is short-circuited by 150
Ω
.
In the state of the Table 2-6
q
, The noise level obtained with an output terminal shall be less than -64 dBu.
(equivalent input noise -128 dBu).
In the state of the Table 2-6
w
, The noise level obtained with an output terminal shall be less than -88 dBu. (equivalent
input noise -108 dBu).
"12.7 kHz Low path filter is used when carrying out noise measurement".
2-14. Phase
In the state 2-1 from 2-5, the phase of the input signal and the output signal shall be the same.
INPUT
Pin 1: GND
Pin 2: + (HOT)
Pin 3: - (COLD)
OUTPUT
D-sub 25-pin connectors
Euroblock connectors
2-15. +48 V (PHANTOM)
Connect a 10 k
Ω
load resistance between the pin 1 and 2 of the INPUT and short-circuit between the pin 2 and 3.
Turn on the +48 V switch and the voltage between pin 1 and 2 shall be 35
±
3 V.
