3 INTRODUCTION In short, all the complex interconnected components in the system ar e designed to work in harmony with each other to produce the best possible sound.
4 1. Connect the line-level monitor signal from your mixer (or other signal source) to the SIGNAL INPUT jack on the HR824 Studio Monitor ( 1 ⁄ 4 -inch TRS, XLR, or RCA). 2. Connect the supplied AC power cord to the IEC socket on the back of the monitor .

8 REAR P ANEL DESCRIPTION INPUT SENSITIVITY NORMAL OFF INPUT SENSITIVITY – 10 d B The HR824 expects a line-level signal at its input connectors. • The refer ence sensitivity is –7.5 dBu=100 dB SPL at one meter (39 inches) with the INPUT SENSITIVITY control set to its NORMAL position (in other words, wide open).
9 somewhat. Low-frequency information r equires the largest amount of an amplifier’s output, so restricting the low-fr equency content allows raising the mid-frequency level somewhat. If your client insists on mixing LOUD, this may be a workable strategy .
10 Conversely , if your mixes ar e consistently too bright, then adding some additional high frequency energy in the monitors satisfies your ears, and the r esultant mix has less HF content. The timbre of your monitors affects the way that your mixes play on other equip- ment.
11 The HR824 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. Y ou can’t see the passive radiator because it is located at the rear of the cabinet, behind the power amplifier assembly .
12 OL PWR ON FRONT P ANEL DESCRIPTION Overload Protect The high and low frequency power amplifiers have clipping detectors that light the OL LED when either power amplifier output clips.
13 Thermal Protect All amplifiers produce heat. The HR824 is designed to be efficient both electrically and ther- mally . • If for some reason the heatsinks get too hot, a thermal switch activates, placing the HR824 into Standby mode (indicated when the red PWR LED turns off).
14 • If it’s a stereo pair , try switching them around. For example, if a left output is presumed dead, switch the left and right cords at the monitor end. If the problem switches sides, it’s not the monitor . It could be a bad cable, or no signal from the mixer .
