Owner's Manual DLM8/12 Loudspeaker: Rear Panel Features continued... 13. SYS Button DLM loudspeakers have powerful system processing tools built in. Simply press the system [SYS] button repeatedly until the parameter you want to change is highlighted: • EQ • Delay • FX • Feedback Once the parameter you want to change is highlighted, press the + or - button [16] repeatedly until you have achieved the setting you want for the loudspeaker system. Let's take a more detailed look at each of the four factory system preset parameters: EQ: Here you are able to change the loudspeaker's speaker mode to tailor it to best suit your particular application. There are seven modes, including PA, DJ, Soloist, Monitor, EQ K, EQ Y and EQ J. PA Speaker Mode - This mode is full range, but focuses on mid-range clarity where vocals often reside. DJ Speaker Mode - This mode bumps the lows and highs with a mild tuck to the mids, perfect for music playback. Soloist Speaker Mode - This mode features a low frequency roll-off to get rid of unwanted thumps and adds boost and sparkle to mid-range and high frequencies. This mode is perfect for plug-and-play singer-songwriters. Monitor Speaker Mode - This mode features a low frequency roll-off and a reduction around 2 kHz to ensure maximum gain before feedback in monitor applications. KYJ Speaker Modes - These modes mimic the voicings of popular competitive loudspeakers, allowing you to add Mackie DLM loudspeakers to an existing system while maintaining sonic continuity throughout the system. Delay: Delay "delays" the audio signal for a set period of time. With DLM loudspeakers, it's used for aligning delay stacks, balcony fills, etc, not as an effect. DLM delay times range from 0 ms [0.0 feet / 0.0 meters] to 300 ms [337.8 feet / 102.9 meters]. FX: DLM loudspeakers include 16 "gig ready" effects, including various reverbs, delays, choruses and combinations of these, as well. Select your preferred effect from the list then return to channel 1 or 2 [11] to adjust the appropriate level for each source. Be sure to check out a more detailed description of each effect in Appendix D. Feedback desTROYer: The multi-band Feedback Destroyer hunts down offending feedback frequencies and applies up to six notch filters automatically to destroy feedback and maximize gain prior to feedback. This is a great tool for when an engineer is not present. There are four Feedback Destroyer settings to choose from: Off [Default] - The Feedback Destroyer is not engaged. If filters have been applied, this setting will retain its current filter settings if there are any, but they will not be engaged until it is turned back on. This is indicated by the grayed out filter graphic. On - When the automatic Feedback Destroyer is turned on, scanning occurs continuously. The six filters will engage sequentially when feedback is present until all are used and then it will be locked. If feedback is identified on an existing filter, the notch will deepen in three steps to further destroy the offending feedback frequency. Pretty cool, huh?! Clear - This clears all filters. Hold - Hold allows a user to turn off the continuous scan. In this mode, filters that have been applied are still on, but the circuit is no longer looking for feedback. Owner's Manual 13
