The amplilier comes standard as desk mounted with rubber feet but can be rack mounted via an optional rack mou-nt kit (IC3ORMK). The IC30 will deliver 30 \yatts into a load of . l ohms. 7o or lO0 volt line. [. . . ] Adjusting the treble control in a counter-clockwise direction will provide up to -9 dB of treble cut @ lO kHz. 4.

This is a feature of the IC series amplifren, which is equipped with a current Umiting circuit prwenting excessive DC c'urrents, thus eliminaring the risk of blowing high tension fixes. In the unlikely event that the DC fuse actuats, the outtrrt IC's should be checked, as it is probable that the amplifier has been subjected to very extreme conditions. [. . . ]
