Verify that the TIP-ground AC voltage matches
the RING-ground voltage and that the level is
less than 5VAC rms. If not, common 60Hz noise
may convert as audible noise on the line.
Verify that the longitudinal balance is greater than
60dB.
Verify that the Power Noise measured on the line
is lower than 80dBrnc
Verify that the Circuit Noise measured on the line
is lower than 20dBrnc
Verify that the BRX-XLR chassis grounding is
properly made. Bad grounding may reduce unit
shielding efficiency and translate into higher
noise coupling.
If the measurements for the copper pair do not match
the above guidelines, please follow the corporate
procedure to rectify the situation and verify again if
the problem is still present.
