The amplifiers in the Impulse 1015P are equipped with DDT™ and an LED indicator to show it has engaged. If the sound seems heavily compressed and the DDT indicator is lighting more than occasionally, then the drive level from the mixer (or the Volume control on the Impulse 1015P) needs to be reduced.
When first turning on the sound system,
USING THE MIC INPUT WITH SIMULTANEOUS MUSIC PLAYBACK
With the mic input (8) switched on (7), a signal will be sent to the Impulse 1015P preamp electronics. Be sure to keep the mic away from the front of the speaker after switching the mic input ON and during level setting of the microphone, as very loud feedback will occur! The recommended placement of the person using the microphone is to the side and slightly to the rear of the Impulse 1015P, not out in front of the speaker system. When not using the mic input, be sure to switch off the mic (7) for the lowest noise and hum pickup.
Set the microphone level using the Volume control (6), the sound source may be louder during the actual presentation, and there is also the possibility that the microphone may be brought closer to the front of the speaker later on. For best results, the microphone should be held close to the user mouth instead of a foot or more away. Do not “eat” the mic that is, do not put your lips right on the mic, as this can often result in a boomy sound. The best results are obtained when the mic is approximately
When using the mic input (8) and the regular inputs (5) for simultaneous music, speech or singing, the volume for the mic should be set first using the Level control (6) as described above. The level fed to the regular inputs should be set to the desired level and matched to the microphone levels using the source Level Control or mixer.
