  • Page 3: Introduction

    So we recruited some of the best speaker and acoustic engineers in the indus- try to assist in the design of the HR824. And we invested in some advanced (and need we say expensive) measurement and analysis tools for the design team to use.

    There are a number of other settings you can make on the back of the HR824, and you can look at the graphic instructions relating to each of them on the back of the cabinet (or wait until you read about them later on in this manual so you really know what they do).

  • Page 9: Low Freq

    The LOW FREQ switch inserts a steep low- frequency rolloff into the response curve. • For many applications, the low-frequency output of the HR824 may impair your ability to make mix judgements. • For most applications, use the 47Hz setting.

    ON.) • Since the power supply and low level circuitry are already active (assuming the speaker is plugged into a live outlet), this is an “instant on” function. • When it’s in the AUTO ON position, the amplifiers turn on and off depending on the presence or absence of an input signal.

    You can either make or purchase a speaker- level to line-level attenuator to reduce the signal from the receiver’s speaker output so it can be connected to the HR824’s input. The following illustrations show how to make an attenuating pad for the balanced XLR and TRS connectors.
