Service Info
Details concerning Warranty Service are spelled out on the Warranty Card included with your monitor (if it’s missing, let us know and we’ll rush one to you).
If you think your monitor has a problem, please do everything you can to confirm it before calling for service, including reading through the following Troubleshooting section. Doing so might save you from deprivation of your monitor and the associated suffering.
Of all Mackie products returned for service (which is hardly any at all), roughly 50% are coded “CND” — Could Not Duplicate, which usually means the problem lay somewhere else in the system. These may sound obvious to you, but here are some things you can check:
Troubleshooting
No Power
•Our favorite question: Is it plugged in?
•Make sure the power cord is securely seated in the IEC socket and plugged all the way into the AC outlet.
•Make sure the AC outlet is live (check with a tester or lamp).
•Are the power switch on the front panel and the POWER MODE switch on the rear panel in the ON position?
•Is the PWR LED on the front panel illuminated? If not, make sure the AC outlet is live. If so, refer to “No Sound” below.
•If the PWR LED is not illuminated, and you are certain that the AC outlet is live, it will be necessary to have the HR824 serviced.
There are no
No Sound
•Is the PWR LED on the front panel illuminated? If not, refer to “No Power” above.
•Is the INPUT SENSITIVITY control turned up?
•Is the signal source turned up? Make sure the signal level from the mixing console (or what- ever device immediately precedes the studio monitor) is high enough to produce sound.
•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 a 1⁄4” TS or TRS plug, make sure it is plugged all the way in.
•Is it loud and distorted? Reduce the signal level at the mixer.
•If possible, listen to the signal source with headphones plugged into the preamp stage. If it sounds bad there, it’s not the monitor.
•Too much bass or not enough bass? Move around the room and see if the bass response changes. It’s possible your listening position coincides with a room mode where the low frequencies either become exaggerated or nulled. If so, try moving the monitors to a different position, or moving your listening position.
Noise/Hum
•Check the signal cable between the mixer and the monitor. Make sure all connections are secure. These problems usually produce crackling noises or hum.
•If connecting an unbalanced output to the HR824 balanced input, make sure the shield is connected to the unbalanced ground and to pin 1 of the XLR (or the sleeve of the TRS jack).
•If a CATV cable is connected to the system, try disconnecting it. If the hum goes away, call your cable carrier to check for proper grounding of the cable.
