® Section 4 DriveRack PA Detailed Parameters The DriveRack® PA offers complete editing flexibility, by offering in-depth control over every parameter within each effect module. The following section will provide you with descriptions and explanations of all parameters within the DriveRack® PA. 4.1 Pre-Crossover The DriveRack® PA’s Pre-Crossover EQ section may be configured as a single or linkable 28 band graphic EQ. EQ On/Off Turns the GEQ on and off.
PAGE 43
® DriveRack PA Detailed Parameters Section 4 Clear Live/All This parameter clears the filters. If Clear Live is selected, then (if invoked) the live filters are reset. If Clear All is selected, then (if invoked) all of the filters are reset. When either Clear Live or Clear All is selected, the third parameter row displays “Start w/ Data Wheel.” If Clear (none) is selected, then nothing is displayed on this row.

Section 4 ® Detailed Parameters DriveRack PA 4.3 Subharmonic Synthesizer The Subharmonic Synthesizer module has been specifically optimized to enhance Bass audio material for use in a variety of professional applications, including nightclub and dance DJ mixing, theatre and film sound, music recording, live music performance and broadcasting.
PAGE 45
® DriveRack PA Detailed Parameters Section 4 4.5 Post-CROSSOVER PEQ In addition to the pre-crossover EQ options within the signal path, the DriveRack® PA also offers a 2 or 3-band parametric EQ after the crossover section. The parameters for the post-crossover EQ are as follows and are user adjustable. PEQ On/Off Turns the PEQ band on and off. The following figure shows the constant Q parametric filter. Flatten/Restore This parameter either flattens the PEQ or restores the PEQ to its original shape.
PAGE 46
Section 4 ® Detailed Parameters DriveRack PA 4.6 Compressor/Limiter The DriveRack® PA also offers Compression and Limiter modules. The Compressor is a full bandwidth Stereo Compressor located prior to the Crossover. The Compressor is the perfect tool for tightening uneven signal sources such as vocals and guitars. The Limiters are located on each stereo output channel and have been strategically placed for speaker and amplifier protection.
PAGE 47
® DriveRack PA Detailed Parameters Section 4 LIMITER Limiter On/Off Turns the Limiter module on and off. OverEasy (O) Off to 10 There are ten levels of OverEasy® that can be used for the limiters. The point when the compressor starts to compress is the "knee." When the compressor starts to reduce the level of a signal abruptly as it passes over the threshold this is called "hard knee" compression. OverEasy® (soft knee as it is sometimes called) is when the volume of the sound is compressed gradually.

Appendix A ® DriveRack PA A.1 Factory Reset In the event that a reset is required, the DriveRack® PA offers you the option of performing a “Soft” or “Hard” reset. The Soft Reset resets all operating parameters except user programs. The Hard Reset Procedure will reset all programmable information back to the factory defaults. All Power-Up Functions require a button(s) to be pressed and held as the unit power is turned on. DriveRack PA Power-Up Button Functions Factory (“Hard”) Reset.

You may be able to see if a lifted band is a mode by manually adjusting a lifted EQ band - if no change in the EQ is perceived, you probably are seeing a mode in your frequency response. To reduce the effect of this mode, try different microphone positions and adjust the location of your speakers, then repink the room for a more effectual Graphic EQ adjustment.

® DriveRack PA Appendix A A.8 System Setup and Gain Structure The DriveRack PA offers a wide range of tools for sound system design and setup. These tools can make your system more efficient and better sounding, but to get the best possible sound it is important to use these tools properly. In the DriveRack PA we have included a Wizard setup tool to help in system setup. If you use the Wizard to set up your DriveRack PA it will automatically set the limiters for some amplifier selections.
PAGE 62
Appendix A ™ DriveRack Once you have found the clip point of your amplifiers, you can mark this position and turn the amplifiers back up to the point where they are clipping. You can now use the output limiters in the DriveRack PA to protect the amplifier from clipping no matter what you do at the console. With the amplifiers clipping, now go to the Limiter page of the DriveRack PA and turn the limiter for each output band on. Make sure that the threshold is all the way up to +20dB.
