Functions description PROTECT INDICATOR This LED lights up for a few seconds after the iA 480X is powered on and then turns off if the amplifier is not damaged. This LED also lights when overheating or other service problems occur. It is normal for the protection LED to fade slowly when the amplifier is powered off. SIGNAL CLIPPING INDICATOR Lights whenever the channel is outputting signal at full strength and signal is distorted. Reduce signal level to ensure undistorted output signal.
BALANCED PHOENIX AND STEREO RCA INPUT Connect audio signal to electronically balanced phoenix connector or to stereo RCA. Please note that the iA480X needs at least 0 dBu to achieve maximum power. INPUT GAIN CONTROL This control allows you to precisely adjust the input level of the signal arriving at the rear-panel input connectors. At their fully counterclockwise position, the signal is attenuated by -80 dB. At their fully clockwise position, the signal is no attenuated.
