Mackie Studio Monitors HR624 MK2 Problems

These Mackies beloved by users all over the world can suffer from a strange and rather annoying problem of volume reduction after a few years use. I don’t mean volume fluctuation; I am talking about a permanent reduction in output level – up to 80-90% in some cases. That is a hassle that we well can do without from our beloved monitors that we rely upon as a reference every day.

This gradual reduction of volume level can be hard to detect. After all, you might not notice it as it creeps up gradually over a few years and you get accustomed to it. The real clue to it is when the problem gets so bad that you think the monitors are unusable or when you notice that you have to excessively compensate for imbalance between a pair by increasing the input signal from your mixer or bumping up the volume control on the rear. The tone of the speakers does not seem to be noticably effected but I suspect that it is but we just get used to it over time.

The cause of the problem is that a couple of capacitors in the signal chain dry out over time and then instead of allowing signal to pass tranparently strangle it off instead. The only solution is replacement of course.

If you would like to get your speakers fixed please get in touch via the contact form. I can even take care of this via a courier.

If you are feeling brave and would like to try this repair your self then I can supply a PDF fact sheet illustrating what you need to do for this there is a small charge.

Mackie Studio Monitors HR624 MK1 Problems

Mackie Studio Monitors HR624 MK1 – no power or wont stay on.

These great little monitors suffer from a regular power failure problem where they will not turn on.  Not always, but quite often, this is actually a fault with the standby circuit which shuts the amp off as it thinks the input signal is too low. 

The solution is remarkably simple and just involves the replacement of a few capacitors.  If you think you might be affected by this issue get in touch as amp repair is less than you think.  Individual amps cost 1.5 hours time and a pair can be done for 2.5 hours + postage.

Best thing is to remove the amp from the cabinet by undoing the 8 torx screws on the back and packing the amp up and sending it in to me.
