    5. Water and Moisture — Do not place water, hot or chilled drinks on top of this Mackie Product as it may cause a shock hazard. This Mackie product should not be used near water; for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool, swamp, or salivating St.
  • 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 HR624. And we invested in some advanced (and need we say expensive) measurement and analysis tools for the design team to use.
  • Page 4: Quick Start

    There are a number of other settings you can make on the back of the HR624, 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 5 Set the Voltage Selector Switch to “120” for 100-120 VAC mains, and to “240” for 220-240 VAC mains. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE. DO NOT REMOVE COVER. NO USER SERVICEABLE PARTS INSIDE.

    SPL at one meter (39 inches) with the INPUT SENSITIVITY control set to its NORMAL position (in other words, wide open). • The HR624 is designed to operate with a +4 dBu signal when the INPUT SENSITIVITY control is in the NORMAL position.
  • Page 9: Low Freq Filter

    The LOW FREQ FILTER switch inserts a low-frequency rolloff into the response curve. • For some applications, the low-frequency output of the HR624 may impair your ability to make mix judgements. • For THX applications, use the 80Hz setting. • For non-THX applications where a sub- woofer isn’t enhancing low frequency...
  • Page 10: Power Mode

    Conversely, if your mixes are consistently too bright, then adding some additional high frequency energy in the monitors satisfies your ears, and the resultant mix has less HF content. The timbre of your monitors affects the way that your mixes play on other equip- ment.
  • Page 11: Mains Input

    Below this frequency, the frequency response falls at 24 dB/octave or more. The HR624 is a bass reflex 6th-order system. Rather than use ports, the vent takes the form of a passive radiator, a mass-loaded flat piston coupled to the air trapped within the enclo- sure.

    HR624! Speaker levels are much higher than line levels and can damage the input circuitry in the HR624. You can, however, insert a speaker-level to line-level signal attenuator between the receiver’s speaker output and the HR624’s input.
  • Page 14: Service Info

    • If the power LED is not illuminated, and you are certain that the AC outlet is live, it will be necessary to have the HR624 serviced. There are no user-serviceable parts inside. Refer to “Repair” at the end of this section to find out how to proceed.

    4. Pack the monitor in its original packing box. This is very important. When you call for the RA number, please let Tech Support know if you need new packaging. Mackie is not responsible for any damage that occurs due to non-factory packaging.
