[. . . ] · For THX applications, use the 80Hz setting. · For non-THX applications where a subwoofer isn't enhancing low frequency output use the 49Hz (NORMAL) position. · The LOW FREQ switch affects the lowfrequency content of your mix. Remember how things work in reverse, so removing the deep bass content on playback may actually increase it in the final mix. · You can use the LOW FREQ switch's 80Hz position to simulate a smaller loudspeaker, especially one with limited low-frequency capability (like a certain popular 2-way nearfield monitor). You may need to do this if a small speaker is the eventual destination of your mix, or perhaps just to see how your mix sounds on a clock radio. Removing the low-frequency content also allows you to raise the overall output level somewhat. Low-frequency information requires ­3dB ­10dB QUARTER ­2dB 0 +2dB (NORMAL) HIGH FREQ FILTER THX = 0 dB The HIGH FREQ FILTER switch tailors the overall high-frequency response by ±2 dB beginning at 10kHz. Leave this switch in the 0 (NORMAL) position unless: · You want to subtly brighten or darken the sound of the speakers. · Perhaps you have hearing loss caused by too many nights in front of a double Marshall stack. · You just like to mix on the bright side or dull side. If your mixes consistently sound dull or dark when you listen elsewhere, this usually indicates that your monitors are too bright, relative to your normal hearing. A bit less high-frequency energy usually fixes this, and you can force the mix in this direction by reducing the highfrequency output of the monitors by using the ­2 dB position of the switch. 49Hz +1. 5dB 52Hz 20kHz ­ ­ 22 kHz ­3dB WHOLE (NORMAL) A C OFF NORMAL B HALF 80Hz LOW CUT 49Hz (NORMAL) ­2dB 0 +2dB STANDBY AUTO ON ON (NORMAL) INPUT SENSITIVITY ACOUSTIC SPACE LOW FREQ FILTER HIGH FREQ FILTER TM POWER MODE INTERNAL BI·AMPLIFICATION 100W L.

The timbre of your monitors affects the way that your mixes play on other equipment. Remember that the monitors have a mirroring effect on the mix; if the monitors make something too loud in the mix it usually results in not enough of that thing on tape. Start with the response modification switches in the factory recommended settings (see Quick Start Section). After prolonged listening, if you notice a trend in your mixes, perhaps making some small adjustments as suggested here will help. It's a real rush to mix really loud. But remember that the resulting mix only sounds good when you play it at least that loud.
