  • IEQ...the eq of the future!

    The IEQ brings the familiarity and feel of analogue graphic equalisers into the digital world. Many digital equalisers of the past have employed menu driven control which makes their use cumbersome. The IEQ has a user interface identical to analogue units with a plethora of features at hand. The addition of user defineable AFS & Limiting is a blessing for live applications. Additional features such as Noise Reduction & Low-Cut Filter truly make the IEQ a complete package.
