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. The T ransducers... The monitors featur e an 8.75-inch die-cast magnesium frame woofer and a 1-inch viscous edge-damped aluminum-alloy dome tweeter on the front, and a 6-inch x 12-inch[...]

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 . Plug the other end into an AC outlet properly configured with the corr ect voltage for your p[...]

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). • The HR824 is designed to op[...]

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 . HIGH FREQ HIGH FREQ 0 (NORMAL) – 2dB + 2dB The HIGH FREQ switch tailors the overall high-[...]

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. Remember that the monitors have a mirroring effect on the mix; if the mo[...]

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 . • Simple ports or ducts mu[...]

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. • If you see the OL LED blinking more than just occasionally , it’ s an indication that you should reduce the signal level coming from your mixer or other sign[...]

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). • Should this happen, make sure that airflow to the rear of the cabi[...]

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 . Bad Sound • Is the input connector plugged completely into the jack? If using[...]
