14 MUL TIGA TE PRO XR4400 5. TECHNICAL BACKGROUND 5. 1 EXPANDER mode As already described, a so-called downward expander automatically reduces the overall level of all signals that drop below an adjustable threshold, and thus expands the dynamic range of the program material.
15 MUL TIGA TE PRO XR4400 5.2 .2 Attack, release and hold times The BEHRINGER MULTIGATE PRO is equipped with a MODE switch as well as a HOLD and RELEASE control to adjust the time-domain parameters that determine the so-called envelope: Fig.

17 MUL TIGA TE PRO XR4400 point of time. Also when synchronizing several instruments, inaccurate entries of individual musicians can be avoided. To expand phase-coherent stereo signals (i.e. signals having the same phase), it is imperative that the control processes be triggered simultaneously in both channels.

19 MUL TIGA TE PRO XR4400 signal will not be suppressed completely. Although the MULTIGATE PRO allows for a maximum gain reduction of 80 dB, it is usually not useful to reduce the signal level by this maximum amount.
20 MUL TIGA TE PRO XR4400 The high sound pressure levels of the individual instruments lead to crosstalk in adjacent microphones. Frequency cancellations and a non-defined sound (comb filter effect) are the result. It has proven wise to use a separate microphone for each drum instrument and to gate each microphone channel.
