Wisdom Wands SC-1 owner manual

the midrange and treble regions is a powerful tool that allows you to “home in” on a good setting that is specific to the room at hand prior to MultEQ Pro doing the finer adjustments.

As an example, we have seen rooms that worked perfectly at the recommended starting setting of a –9 dB HF Trim for the L75i, and another room that required only –2 dB for the exact same speaker. (This was a traveling demo system one of our salespeople was taking from one dealer showroom to the next.) Without the ability to get the system in the right “ballpark” for these extremely different rooms, even MultEQ Pro would have been hard-pressed to yield the results we were looking to achieve.

As an example, we’ll look at the same system, in the same room, with three dif- ferent HF Trim settings, showing both Before and After results using the View Results... button. To keep things simple, the microphone was never moved (not recommended for normal calibrations).

First up is an L75i system with the HF Trim untouched, at 0.0 dB. You can see that the planar section is significantly louder overall than the woofer section. MultEQ respects what it interprets as a low frequency roll off, and there is little energy below about 150 Hz.

This manual suggests an HF Trim of -9.0 dB for the L75i; so our intrepid installer realizes his mistake and resets the system accordingly. The resulting curve now looks like this:

While this isn’t bad (and would be further improved by measuring more posi- tions in the room), it is probably overkill in this room. You are losing more dynamic headroom in the system than is really necessary by pulling down the planar magnetic drivers by the full 9 dB. This would be even more true if there is a subwoofer in the system, since it would be reproducing all the deep bass.

Looking at an HF Trim setting of -5.0 dB yields the following, with the same mi- crophone position.
