  Configuring The DriveRack PA2 This section of the manual describes how to configure the DriveRack PA2 for your application. The easiest way to configure the PA2 is to use the built-in Wizards.

• Page 21: Set Gain Structure & Limiters

  ® The PA2’s output POLARITY parameter (located in the crossover) is used to match polarity between drivers. Some multi-way main speakers will require certain drivers to be polarity inverted when operating in bi-amped mode (bypassing the internal passive crossover network). When selecting any bi-ampable main speaker from the PA2’s speaker tuning list in the Setup Wizard, such polarity inversion will be performed for you automatically.

When you select your amplifiers in the Setup Wizard, the PA2 will automatically set the limiter thresholds and gain structure between the PA2 and amplifiers. If your amplifiers are not available in the Setup Wizard, you should choose the NOT LISTED option.

Go into the PA2’s output limiters and ensure they are 4� all turned OFF, OVEREASY is set to OFF, and their THRESHOLD’s are set all the way up to 0.0 dB. Also, turn off all non-essential PA2 processing if it is enabled (i.e., Compressor, GEQ, Subharmonic Synth, and AFS).

  EQ, which translates to smaller gain adjustments in the EQ and better sound quality. You can perform this procedure while listening to your reference music and do it by ear or use the dbx RTA-M reference mic and RTA. The music you choose to use for reference should contain full-bandwidth audio and should be something you have spent much time listening to and are extremely familiar with.

• Page 25: Ring Out The System With Afs

  ® 6. Ring Out The System With AFS Ringing out the sound system for feedback before use allows you to squeeze a little more gain out of the system before the onset of feedback and can help ensure you’re not right at the edge of feedback during the performance. The AFS Wizard does a great job of taking the guesswork out of ringing out the sound system for feedback.

• Page 27: Managing Presets

  ® Managing Presets The DriveRack PA2 has two types of presets: user and factory. The user presets occupy preset memory locations1–75. The factory presets occupy preset memory locations 76–100. The difference between these preset types is that factory presets are meant to be used as templates and cannot be overwritten and user presets can be overwritten and are designed to store your custom presets.

• Page 29: The Pa2 Processing Modules & Parameters

  ® The PA2 Processing Modules & Parameters This section of the manual provides descriptions of all the processing modules available in the DriveRack PA2 and their associated parameters. Graphic EQ (GEQ) The 31-band GEQ module lets you manually tune the sound system’s frequency response and is meant to be used alone or alongside the AutoEQ PEQ (which is set when you run the AutoEQ Wizard).
• Page 30 ® • MYBAND This option is optimized for live music performance using a portable PA system in small to medium sized venues (coffee shops, clubs, etc.). It offers some low-end boost along with low-mid cut, which enhances the low end while preventing the system from sounding too muddy.

• Page 31: Parametric Eq (autoeq, High, Mid, Low Peq)

  ® Parametric EQ (AutoEQ, HIGH, MID, LOW PEQ) There are two types of PEQs available in the PA2: the AutoEQ PEQ and the output PEQs (labeled LOW, MID, and HIGH). The AutoEQ PEQ is an 8-band parametric EQ which resides in the input processing side of the PA2 (pre crossover) and is automatically adjusted by the built-in AutoEQ Wizard.
• Page 32 ® • [20 Hz – 20 kHz] BAND(1–8) FREQUENCY This parameter adjusts the center/cutoff frequency of the selected EQ band. • [-12 dB – +12 dB] BAND(1–8) GAIN This parameter adjusts the gain of the selected EQ band. • [0.1 – 15.909] BAND(1–8) Q This parameter is only available with BELL type filters and adjusts the width of the selected PEQ filter.

  Suppression) algorithm to help combat this dreadful phenomenon. The AFS algorithm in the PA2 is a little different than the AFS algorithm used in any previous dbx products. That’s because the dbx engineers revisited the already-stellar AFS algorithm to see if they could improve it. And guess what? They did! The updated AFS algorithm in the PA2 can now detect and eliminate feedback faster than ever before and with even higher precision.
• Page 34 ® TIP: AFS works best when the signal entering the PA2’s inputs is sufficient. This requires proper gain staging between the mixer and PA2. If the signal level is too low, AFS may be slow to respond to feedback. See ‘Manual System Optimization Tips’...
• Page 35 ® begin to round robin – meaning that if all Live filters have been set and new feedback occurs, the first Live filter set will be released then re-set at the new feedback frequency location. The Live filters can be set to release after a period of time by enabling the LIVE LIFT option and adjusting the LIFT AFTER parameter.
• Page 36 ® TIP: Since it’s not really possible to predict exactly how many Fixed filters you may need, a good setting to start with is the default setting of 6. If after ringing out the system, you feel you need to squeeze a little more gain out of the system before feedback, you can increase the FIXED FILTERS setting and run the AFS Wizard again or manually ring out only the newly added Fixed filters in the AFS menu.

• Page 37: Subharmonic Synthesis (sub)

  ® Subharmonic Synthesis (SUB) dbx’s subharmonic synthesis (or sub-synth) processing has been specifically optimized to enhance the low frequencies in audio material and was designed for use in a variety of professional audio applications, including nightclub and dance DJ mixing, theatre and film sound, sound design, music recording, live music performance, and broadcasting. Using traditional EQ to enhance this extremely low frequency region can increase noise potential and stage rumble (low-frequency feedback) in live PA systems.
• Page 38 ® NOTE: If you experience low-frequency artifacts on a voice when using subharmonic synthesis, try engaging a high-pass filter, using EQ, or a combination thereof on the vocal’s mixer channel to reduce the artifacts. If a high-pass filter and EQ are not enough, try lowering the overall amount of Subharmonic Synthesis applied to the signal by adjusting the SUBHARMONICS parameter.

• Page 39: Compressor (comp)

  ® Compressor (COMP) A compressor is used to compress the dynamic range of the audio signal, bringing up the lower-level portions of the signal and restricting the higher-level portions of the signal. In live sound applications, it is common to compress the audio at different stages in the signal chain.
• Page 40 ® a 2:1 ratio would allow the output signal level to increase by only 1 dB for every 2 dB of level increase over threshold. In other words, 1 dB of compression will be applied for every 2 dB increase in level above threshold. For light compression, choose a lower ratio.

• Page 41: Delay

  ® Delay There are two different delay module types available in the PA2: the input (also known as pre or backline) delay module and the output (also known as driver alignment) delay module. The output delay modules (labelled HIGH, MID, and LOW) are used to time align loudspeaker drivers which require it. Typically, driver alignment delay is only required when configuring a bi-amplified (2-way) or tri-amplified (3-way) system.

  ® Crossover (XOVER) A crossover is used to divide the broadband signal into separate frequency bands. This allows each loudspeaker or driver in a sound system to be operated within its optimal frequency range. Using an active crossover, like that in the PA2, has the additional benefits of increasing the efficiency of your power amplifiers, lowering intermodulation distortion, and in some cases, improving the drivers’...

When two Linkwitz-Riley filters are summed, there is no increase in level around the crossover frequency, which makes these type of filters very popular.
