Attention!
Cables:
Thisproduct shouldonly beused with high quality, screened twisted pair audio cables, terminated
withmetal bodied3-pin XLRconnectors. Thecable shouldbe connectedto pin1. Anyother cable
typeorconfigurationfortheaudiosignalsmayresultindegradedperformanceduetoelectromagnetic
interference.
ElectricFields:
Should this product be used in an electromagnetic field that is amplitude modulated by an audio
frequencysignal (20Hzto 20kHz),the signalto noise ratio may be degraded. Degradation of upto
60dB at a frequency corresponding to the modulation signal may be experienced under extreme
conditions(3V/m, 90% modulation).
