1.3 Quick Start
For those of you that wish to jump right in, the following information has been provided to act as a quick start guide for
optimizing performance of the DriveRack 260.
Connections
When setting up the DriveRack 260, make connections as follows: • Always make connections prior to applying power to the unit.
• C
onnect the output(s) from the sending device (mixer) to the Ch. 1 XLR input connector (mono) or both, Ch. 1
and Ch. 2 XLR input connectors (stereo).
• Make output connections from the output XLR connector(s), shown below, to the input connector(s) of the
selected power amps. For customers new to the DriveRack 260, we recommended starting with output 1 and then
working up from there. Here are some examples:
• Full Range - Outputs 1 & 2 (all frequencies are passed)
• 2-Way - Outputs 1 & 2 (highs), Outputs 3 & 4 (lows)
• 3-Way - Outputs 1 & 2 (highs), Outputs 3 & 4 (midrange), Outputs 5 & 6 (lows)
Of course you do have options to configure the DriveRack 260 differently than the examples listed above. However, for
the novice user, adhering to the above connection examples will lower the probability of improper configuration.
If you have the optional RTA microphone, connect the microphone to the XLR RTA Mic Input.
IMPORTANT: It is recommended that the power amps are turned off prior to cycling power to the Driverack 260.
Always make sure that your power amps are the last item turned on and the first turned off.
nce all of the connections have been made, and the unit is powered up, you can
O
navigate through the entire signal path of the DriveRack 260 from the front panel of the
unit. The display provides you with a clear and concise overview of each aspect of the
signal path from the input (left side of display) to the output section (right side of display).

SECTION 3 – CONFIGURATION FUNCTIONS
The Configuring section of the DriveRack 260 will be your key to successful navigation of the configuration functions
of the DriveRack. The following information provides, descriptions about program functions and in depth configuration
options of the DriveRack 260.
3.1 Program Definition
The first step in understanding the programming capabilities of the DriveRack is to understand the components of
a complete “program.” Within an individual program, there are several levels of editing that make up the complete
program. When initially entering a program, you will be at the “program” mode level. This level supplies the user with
current program information such as: current signal path, effect usage, and program name/number. From this point, the
DriveRack 260 gives you the option of entering subsequent levels of operation that are dedicated to program editing.
These levels include Configuration mode and Effect Edit mode. All of these components combined, make up the
conventional “program”, and they are all unique to each individual program. The exception is the Utility menu which
is accessed via the Utility button and contains a global set of parameters and therefore, is not part of one particular
program, but rather all programs.
3.2 Navigating Factory Programs
From the factory, the 260 DriveRack ships with 25 factory programs that have been designed to accommodate virtually
any sound reinforcement and installation application. The factory programs offer a clear and concise explanatory title to
get you up and running in a timely manner. These programs can also be used as templates or starting points for the user
to create custom programs.
Selecting Programs:
The quickest way to get up and running with the DriveRack is to use any one of the factory programs that are available
in the box. To select a factory program, (from program mode), use the DATA wheel to scroll through the various
factory programs. As each factory program is selected, the display will clearly indicate the title that is directly related to
a specific application. Once a program is selected, ‘Not Loaded’ will flash in the display. To load this selected program,
press the DATA wheel in (this is the SELECT button). The display will appear something like this:

Once you have selected a program with a configuration that accommodates your application, the DriveRack offers
instant access to edit effect types within the configuration.
To instantly access an effect module, simply press the corresponding button in the button array for the desired module.
3.3 Editing Factory Programs
Once you have reached the module that you wish to edit, use the PREV PG and NEXT PG buttons to move through
the pages within the module. The DATA wheel is used to edit parameter values. The following illustration shows an
example of the Compressor module in edit mode:
Note: The cursor indicates the currently selected parameter for editing. To select parameters to edit from the current
page, press the DATA wheel until the cursor is next to the parameter that you wish to edit.

3.4 Saving Factory Program Changes
Once you are satisfied with the changes that have been made to a factory or user program, the DriveRack allows you to
save these changes to the program as a custom USER program by pressing the STORE button. The first time you press
the STORE button the DriveRack 260 will ask you if you want to store or delete the program. Just press the STORE
button a second time to advance and store the program. The display will now appear something like this:

PRESS <STORE> TO ADVANCE
• Rotate the DATA wheel to select the program to be replaced and press the STORE button and the existing
program will be replaced with the new program. All edits will be saved.
The DriveRack 260 will store up to 25 user programs (1-25) in addition to the 25 factory programs (26-50).
Note: Factory programs cannot be over-written. From the factory, programs 1-25 (User) are the same programs as 26-50
(Factory). The difference is that users can overwrite programs 1-25. However, the factory programs will always reside
in program locations 26-50. If a user attempts to overwrite a factory program (26-50), the DriveRack 260 will move the
program index to the user program location equivalent. For example if trying to store a program to Factory program
location 50, the DriveRack will automatically change the store location to User program location 25. Of course, the user
can then change the user location if desired.

3.5 Creating a User Configuration
The 260 has 25 Factory Presets in which to choose from. For some configurations, you may be able to simply select
one of these presets as a starting point and edit the program from there. In the Quick Start section of this manual,
you saw how you can use the Wizards to configure basic programs (i.e. stereo Full Range, stereo 2-Way and stereo
3-Way programs with mono or stereo subs). The Wizard works especially well if your speakers and amps are in the
list. However, there may be times when the routing in your configuration may need to be changed, you want to
link/unlink processing modules or select different DSP inserts in the signal chain. This is where the Driverack 260’s
User Configuration mode comes in. User Configuration is an ideal feature available in the DriveRack 260. Even with
the versatility of the Factory Preset configurations within the DriveRack, there may be an application that requires a
unique “custom” program configuration. The DriveRack gives you the ability to create a custom routing configuration
by selecting and modifying the modules including: Inputs, pre-crossover EQ, an insert section which includes: Notch
Filter, Compressor, Gates, AGC, Subharmonics Synthesizer and AFS (Advanced Feedback Suppression), Crossovers, postcrossover Parametric EQ, Dynamics, post Delay, Output Gain and Phase. The following information contain a standard
block diagram of the signal path in the DriveRack 260 which can be used as a reference map, as well as step-by-step
instructions for creating custom user configurations.

SECTION 4 – DETAILED PARAMETERS
The DriveRack 260 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 260.
4.1 Pre-Crossover EQ (28-Band GEQ or 9-Band PEQ)
The DriveRack 260’s Pre-Crossover EQ section may be configured as a single or linkable 28 band graphic EQ or 9-Band
Parametric EQ.
GEQ
EQ On/Off
Turns the EQ on and off.
Flatten/Restore
This parameter either flattens the GEQ settings (sets all bands to 0 dB) or restores (think of this as ‘undo’) the GEQ to
the last settings before flattening. The DriveRack unit allows you to leave the EQ edit window and return without losing
the edited EQ settings.
Frequency (F) 31.5Hz to 16.0kHz
This parameter allows you to select any one of the 28 available frequency bands.
Gain (G) -12 to +12 dB
This parameter allows you to adjust the level of any one of the 28 bands of the GEQ in .5 dB increments.
PEQ
EQ On/Off
Turns the PEQ on and off.
Flat Set/Undo
This parameter either flattens (sets all bands to 0 dB) or restores (think of this as ‘undo’) all bands to their original
settings.
Band 1 Frequency 20 to 20kHz (Low Shelf)
Selects the frequency of the low pass shelf parametric EQ.
Slope 1 3-12dB/Octave
Sets the slope of the low shelf parametric EQ.
Level 1 -12 to 12 dB
Sets the overall gain of the shelf EQ.
Band (2-8) Frequency 20 to 20k
Selects the frequency of the selected band of the parametric EQ.
Q (2-8) 0.20 to 16.0
Adjusts the Q of the selected band of the parametric EQ.
DriveRack® 260 User Manual
27
Section 4
DriveRack

Detailed Parameters
Level (2-8) -12 to 12 dB
Sets the overall level of the selected parametric EQ frequency.
Band 9 Frequency 20 to 20k (High Shelf)
Selects the frequency of the high shelf parametric EQ.
Slope 9 3-12dB/Octave
Sets the slope of the high shelf parametric EQ.
Level 9 -12 to 12 dB
Sets the overall gain of the high shelf parametric
4.2 Feedback Eliminator
The DriveRack 260 offers the exclusive patent pending AFS (Advanced Feedback Suppression) feedback elimination
module. Feedback is caused when a microphonic signal such as a guitar pickup or microphone is reproduced with
amplification and is repeatedly picked up in phase. The AFS uses Precision Frequency Detection and state-of-the-art
processing to determine the exact portions of a given frequency of your feedback that need to be removed (instead
of taking out large sections of your sound). The AFS module of the DriveRack 260 allows the user to optimize the
elimination of feedback. In the past, graphic equalizers were used to eliminate feedback from a system. This was an
acceptable method for eliminating feedback, but when this method was precision tested, the result clearly showed that
a single 1/3 octave EQ slider was removing approximately half of the signal power. With AFS, the module removes the
feedback automatically and the proprietary, precision AFS filters remove only a fraction of the frequency spectrum. The
following diagram shows AFS as opposed to competing, competitive feedback eliminators and conventional graphic EQs:
AFS On/Off
Turns the AFS module on and off. If AFS is Off, the filters are bypassed, and the algorithm is halted (the filters are not
updated). If AFS is On, the filters are active, and the they are updated according to the current selected mode (Fixed or
Live).
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 “Clear w/ Data Wheel.” If the Clear field is blank, then nothing is displayed on this row. To clear filters move
the cursor down to the ‘Clear w/ Data Wheel’ row, then turn the Data Wheel. ‘Clearing Filters...’ will appear in the
display.
Mode - Live or Fixed
When the mode is set to Fixed, the algorithm updates only the fixed filters. When the mode is set to Live, the algorithm
updates only the live filters. In FIXED mode, the system is forced into feedback by the user and filters are automatically
assigned to a frequency which is
28
DriveRack® 260 User Manual
DriveRack

Detailed Parameters
Section 4
creating feedback. FIXED mode is used before the performance without any input signal. In LIVE mode, the live filters
automatically detect and remove feedback during the performance. When all of the live filters have been used, they
begin to round robin. Essentially this means that the first filter set is replaced where a new feedback is detected and
notched out. This mode is useful because feedback frequencies may change as the microphone is moved, and/or as the
characteristics of the venue change. Note that only the fixed filter settings will be stored with the new program. Live
filters clear whenever the unit power cycled, the user loads a different program, or the user clears the filters using the
‘Clear all Filters’ function.
Type - Speech, Low Music, Medium Music and High Music
If Fixed or Live mode is chosen, the text will read “Type.” The options will be Speech, Music Low, Music Medium and
Music High. These types pertain to the Q, sensitivity, and algorithm type. Values are; Speech (Bandwidth = 1/5 octave
and Q=7.25) Music Low (Bandwidth = 1/10 octave and Q=14.5) Music Medium (Bandwidth = 1/20 octave and Q=29)
Music High (Bandwidth = 1/80 octave and Q=116). Note: To guarantee that feedback is suppressed at lower frequencies,
the AFS may place wider notch filters at these lower frequencies (below 700 Hz).
Number Fixed - 0-12
This will range from values 0-12. The total number of filters is the total number of filters available, and the number of
live filters will be = Total Num Filters – Num Fixed. If this is changed before the filters are reset, then the filters will
be reset one by one as the number changes. For example, if the number of Fixed filters goes down, then the last fixed
filter set will be reset. Likewise, if the number of Fixed filters goes up (and thus the number of live filters goes down),
then the last live filter set will be reset. The Fixed/Live filter usage will be indicated at the bottom of each page of the
feedback elimination effect. ‘F’ indicates an available fixed filter, and ‘L’ indicates an available live filter. A blocked out F
or L indicates a filter that is set, or in use.
Live Filter Lift (On/Off)
This parameter turns the Live Filter Lift on and off.
Lift After - 5 sec to 60 min
This parameter allows the user to setup the box so that the Live filters will automatically be removed after a set time (as
indicated by the “Lift After” parameter). It ranges from 5 seconds to 60 minutes. This feature is useful if the microphone
being used is moved or the characteristics of the venue change over time. As example; a filter placed minutes ago will
not be presently preventing feedback. This feature removes unnecessary filters from the spectrum to increase sonic
quality. If the feedback is still there (after the filter is removed), it will catch it and notch it out the same.
Total Number of Filters 1-12
This parameter selects the number of filters being used
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. The Subharmonic Synthesizer module’s two separate bands of subharmonic
synthesis provide the best combination of smoothness and control.
Sub-Harmonic Synth - On/Off
Turns the Subharmonic Synth module on and off.
Sub-Harmonics Synth - 0 to 100%
This parameter sets the overall level of the Subharmonic Synthesizer.
DriveRack® 260 User Manual
29
Section 4
DriveRack
®
Detailed Parameters
24-36Hz and 36-56Hz (Subharmonic Synthesis) Level - 0 to 100%
These controls individually let you customize the amount of the respective synthesized frequencies to be added in,
tuning the ultimate bass response of your system to taste. For example, if the sound is too woofy or growly, try turning
down the 36Hz-56Hz level. If your
woofers are bottoming out (making a ticking, popping sound), try turning down the 24Hz-36Hz level. You may find
that a setting produces fine results in one room, but produces too much boominess in another. If this occurs, adjust the
controls as needed, (e.g., decrease one or the other of the band levels). Experimentation will pay off with smooth, full,
deeply extended bass. Remember, you are not selecting a frequency. You are controlling the overall level of each band.
4.4 Gate
Gate On/Off
Local (per band control) or global on and off.
Threshold -50 to 20 dBu
The threshold is the volume level at which the gate opens. Anything above the threshold passes, while signal that is
lower than the threshold is attenuated. Beware, setting the threshold to high can cut off the tail end of signals as they
fade out (the sustain of a guitar note, a held piano chord, a reverb tail, etc.).
Ratio 1:1.0 to 1:15
This is where you decide how much downward expansion you want. This ratio works opposite from that of the
compressor or limiter. If a ratio of 1:4 is selected, a signal that is 1dB below the threshold will be reduced in gain so that
it becomes 4dB below the threshold.
Attack 0.1 to 200 m Sec
As the signal reaches the threshold area, the Attack control sets the speed at which the gate opens. Use very fast attack

Hold 0 to 500 m Sec

4.5 Automatic Gain Control (AGC)
The AGC is used to keep the average level of a signal at a constant level. This is done by selecting a desired Target
output level and Window. The AGC keeps the signal within the Window about the selected Target by slowly adjusting
the gain. The maximum gain that can be applied to the signal is selected by the Gain parameter. When the input signal
falls below the Low Threshold the AGC releases the gain and returns to unity. This prevents the AGC from adding gain
when there is no signal present and raising the system noise floor. High level signals are reduced by a fast limiter to
prevent distortion by clipping. The AGC Threshold meters show what region of the AGC the input signal is in. The T
(yellow) indicates the signal is within the Window. A + (red) indicates the signal is going into the Limiter. A – (green)
indicates the AGC is adding maximum Gain and is at or below the Window. When the Threshold meter is off the signal
is below the Low Threshold.
AGC: On/Off
Turns the AGC module On and Off.
Target: (Targ) -20 to 20 dB
The Target parameter defines where you would like the average level of the AGC output to be. If the average level of
the signal rises above the Target the gain will be reduced. For signals with an average level below the Target the gain
will be increased.
Gain: 1 to 20dB
This adjusts the maximum amount of gain that can be added by the AGC.
Window: 1 to 10dB
This adjusts the amount of variation in the output
Low Threshold: -60 to -30dB
The Low Threshold sets a lower limit to the AGC. This prevents the AGC from adding gain to low level signals or noise.
Attack: 0.20 to 5 Seconds
Adjusts how fast AGC will reduce gain when the signal level is above target.
Release: 30.0 to 1 dB/Second
Adjusts the rate of gain increase when the signal level drops below target.

4.7 Crossover
The Crossover is used to divide the input signal into several frequency bands. This allows the user to drive the speaker
in its optimum frequency range and send each output separately for more efficient use of amplifier power. The
DriveRack 260 Crossover can be configured as a 2x2, 3, 4, 5, or 6 (stereo configurations) or 1x1, 2, 3, 4, 5 or 6 (mono
configurations). Appendix A.5 illustrates each of the available crossovers. The High-Pass or Low-Pass filter being edited

4.9 Compressor/Limiter
The DriveRack 260 also offers Compression and Limiting modules. The Compressor is a full bandwidth Stereo
Compressor inserted prior to the Crossover. The Compressor is the perfect tool for tightening uneven signal sources,
providing a more even mix. The Limiters are located
on each output channel and have been strategically placed for speaker and amplifier protection. Note that Compressor/
Limiter threshold metering can be observed in the Meter section by pressing and holding the UTILITY button. The
parameters for the Compressor/Limiter are as follows and are user adjustable.
COMPRESSOR
Compressor On/Off
Turns the Compressor module on and off.
OverEasy (O) Off to 10
There are ten levels of OverEasy® that can be used for the compressor. 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
DriveRack® 260 User Manual

Section 4
DriveRack
®
Detailed Parameters
of the sound is compressed gradually. OverEasy® compression starts to compress before the level of the signal reaches
the threshold and reaches full compression after the level has gone above the threshold. OverEasy® compression, by its
very nature, sounds much smoother and more natural and will be used for most applications. When it is gentle (natural
sounding or light) compression that you are looking for, the compressor offers VariKnee™. VariKnee™ gives you ten
levels of OverEasy®
compression to choose from (1 being almost hard knee and 10 being the softest (most gradual) knee). This lets you
choose the exact knee that is needed for the dynamic effect you are looking for. If you are unsure where to set this
parameter, a setting of 4 is a great place to start.
Threshold (T) -40 to +20dBu
Threshold is the signal level at which the unit starts to compress the signal. If the level is set to -10 dBu, than any signal
larger than -10 dBu is compressed while any signal that has a level that is lower than -10dBu is left at the same signal
level. Light compression is where only the loudest parts of the signal go over the threshold. Very heavy compression can
be achieved by setting the threshold low enough that almost the entire signal content is over the threshold. For most
signals the most natural compression is achieved when most of the signal content remains just below the threshold and
only the peaks cross the threshold.
Ratio (R) 1.0 to Inf:1
Ratio is the amount the unit reduces the signal level of the sound that is above the threshold. A 2:1 ratio means that
if the incoming signal is 2dB over the threshold the unit will compress the signal, and outputs a signal that only goes
1dB over the threshold. For light compression choose a lower ratio, while heavy compression requires a higher ratio. A
setting of Inf:1 makes the compressor act as a limiter.
Gain (G) -20 to +20 dB
This parameter is used to compensate for the gain lost during compression. By using heavy compression on a signal and
then boosting the signal with the output gain, the user can create a signal that sounds much louder than it actually is.
Auto On/Off
When Auto Mode is on, the 260 automatically sets the Attack, Hold, and Release times for the signal. The auto mode
constantly adjusts these parameters in real time for optimum performance. You will find that for most applications, not
only is using the auto mode faster and easier but by letting the unit constantly tweak these parameters for you will result
in a better end result (try and hit a snare exactly the same for three minutes).
Attack 0.1 m Sec to 200 m Sec
Attack is how fast the compressor starts to compress the signal after it passes the threshold. Fast attack is useful when
dealing with lots of fast transients. The attack control is not active when in auto mode.
Hold 0 to 500 m Sec
Hold is the time the 260 remains in compression after the signal has dropped below the threshold. A longer hold time is
useful in smoothing out the sound when compressing several fast peaks that are fairly close together in time. In general
some hold time helps to make the compression sound more natural but too much can over compress your signal
making for an unwanted drop in level. The hold control is not active while in auto mode.
Release 360 dB / Sec to 5 dB / Sec
Release is how fast the 260 comes out of compression. The release is in dB per second. For example, if release is set to
5 dB /sec, and the signal is at 10dB of gain reduction, the release time is 2 seconds. Too fast a release time can result in
an audible volume jump, while too slow a release time can result in compression of signal that is not above threshold.
This can cause volume drops in your signal that may not be desired. The release control is not active while in auto
mode.

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 limiter starts to limit is the
“knee.” “Hard knee” limiting is when the limiter starts to reduce the level of a signal abruptly as it passes over the
threshold. OverEasy® (soft knee as it is sometimes called) is when the volume of the sound is limited gradually.
OverEasy® limiting starts to limit before the level of the signal reaches the threshold and reaches full limiting after the
level has gone above the threshold. This OverEasy® limiting, by its very nature sounds much smoother and more natural
and will be used for most applications. When it is gentle (natural sounding or light) limiting that you are looking for,
the limiter offers VariKnee™. VariKnee™ gives you ten levels of OverEasy® limiting to choose from (1 being almost hard
knee and 10 being the softest (most gradual) knee). This lets you choose the exact knee that is needed for the dynamic
effect you are looking for. If you are unsure where to set this parameter, a setting of 4 is a great place to start.
Threshold (T) -40 to +20dBu
Threshold is the signal level at which the unit starts to limit the signal. If the level is set to -10 dBu, any signal larger
than -10 dBu is limited while any signal that has a level that is lower than -10dBu is left at the same signal level. Light
limiting is where only the loudest parts of the signal go over the threshold. Very heavy limiting can be achieved by
setting the threshold low enough that almost the entire signal content is over the threshold. For most signals, the most
natural limiting is achieved when most of the signal content remains just below the threshold and only the peaks cross
the threshold.
Auto On/Off/
When auto is turned on, the 260 will override the manual attack, hold and release parameters and continuously adjust
these parameters automatically.
Attack .01 to 200 m Sec (per band or global)
This is the speed at which the 260 limiter starts to limit the signal once it has crossed the threshold. Set the attack time
longer for lower frequency bands, and shorter for higher frequency bands.
Hold 0 to 500 m Sec (per band or global)
Hold is the time the limiter stays in gain reduction after the signal level has dropped below threshold. Hold is useful
when you want the limiter to function for a period of time after it has been triggered. Be careful not to set the hold time
too long as it will not release in time.
Release 360 to 5 dB / Sec (per band or global)
Just like the release time on the compressor, the limiter’s release time controls how fast the limiter releases from gain
reduction after the signal drops below the threshold. Set the release times longer for lower frequency bands and shorter
for higher frequency bands.
Peakstop+™ On/Off and 1-6
This parameter turns the PeakStop+ limiting on and off. PeakStop+ involves a two-stage process of dynamic limiting. The
first stage of PeakStop+ is the Instantaneous Transient Clamp™ whichclamps the signal with a soft logarithmic clamp
function. This logarithmic function ensures that the signal will not exceed the level set by the PeakStop+™ OVERSHOOT
control by more than the overshoot amount, and that it will not introduce harsh artifacts. The second stage is a unique
program limiter featuring Intelligent Predictive Limiting™. Its function is to monitor the input signal and intelligently
predict the amount of gain reduction needed to keep the output signal below the ceiling set by the Instantaneous
Transient Clamp™. Note that since the PeakStop+™ limiter is a fail-safe limiter, it must come after the OUTPUT GAIN
control.

4.10 Alignment Delay
The DriveRack 260 offers pre-crosssover and post-crossover alignment delay. The post-crossover Delay modules can
be used for delay compensation when speaker drivers are offset from one another, compensation for the difference in
high and low frequency speed, and delay fills. The pre-crossover Delay modules can be used for delaying the system
as a whole, without having to readjust each post-crossover delay module. The parameters for the alignment delay are as
follows and are user adjustable:
Delay On/Off
Turns the Delay module on and off.
Delay Time
Sets the amount of speaker alignment delay time. Delay times include:
• Seconds - 0.00 to 1.3
• Feet - 0 to 1465.1
• Meters - 0 to 445.9
Note: The delay time must be allocated to be available. See section 3.5 “Creating a User Configuration” for information
on allocating delay.
Units - Seconds, Feet or Meters
Selects the unit of measurement for the delay.
4.11 Input Routing (IN)
The signal routing begins at the INPUT ROUTING block of the 260. There are two input routing mixers; they are ‘A’ and
‘B’. These input routing mixers allow you to mix any combination of input channels, 1 and 2, for greater flexibility in
routing. Generally, by default, input Ch. 1 corresponds to input mixer ‘A’ and input Ch. 2 corresponds to input mixer ‘B’,
however this can be changed. For example, inputs 1 and 2 could be mono summed to the ‘A’ mixer for a mono front
of house system, while the ‘B’ mixer also receives a mono summed signal, from inputs 1 and 2, but feeds a delay or
balcony fill. The power in such a setup is that each input routing mixer, ‘A’ and ‘B’, could have completely independent
input signal processing chains and parameters. Therefore, in such a configuration, the user could Auto EQ the front
of house system (input mixer ‘A’ chain) independently from the delay fills (input mixer ‘B chain) and apply feedback
suppression to only the front of house system, while not affecting the delay fills. Each input routing mixer (‘A’ and ‘B’)
contains the following parameters, which are user adjustable on all programs.
Input 1 Level -Inf to 20dB
Adjusts the input level of input 1.
Input 2 Level -Inf to 20dB
Adjusts the input level of input 2.
Master level -Inf to 20dB
This parameter is used to control the overall level of the mixed input signals.

4.12 Output
The output section of the DriveRack 260 provides the user with the ability to control output levels of the unit and
adjust phase compensation of loudspeakers within the signal path. The output level control is located in the signal path
before the limiters; this means that the limiter directly affects the output level. The parameters for the Phase/Polarity
Compensation effect are as follows and are user adjustable. Please refer to section A.7 of the Appendix for a complete
output signal routing diagram.
Shift On/Off
This parameter is used to turn the selected output phase parameters on or off. When Shift is off, phase is 00 and polarity
is positive (+).
Polarity +/This parameter is used to reverse the polarity of the output signal.
Phase 0 to -175 Degrees
This parameter is variable in 5 degree increments and sets the amount of phase shift within the selected output path.
The phase is referenced to the upper frequency of the selected output crossover band.

5.4 Security
The DriveRack 260 does provide a quick front panel System Lockout feature (see Appendix A.2 “Power Up Quick Key
Options” for information on this feature). However, this System Lockout feature requires that the processor be power
cycled to lock/unlock the device. Therefore, the DriveRack 260 also provides you with an additional password protected
security feature to protect all detailed parameter editing and configuration modification settings of your DriveRack unit.
The Utility menu of the DriveRack system includes a complete security system set-up. This security system allows you
to set security access to unit features including: Program List, Store, Mutes, Inputs, Pre EQ, Inserts, Pre Delay, Crossover,
Post EQ, Dynamics, Post Delay, Outputs, RTA and Program Lock, with security levels that vary from low to high (low
having little or no access, medium having some access and high having full access). By providing different levels of
access, this ensures limited access to different users. This security system also allows you to create unique passwords
which will limit/prevent any other users from accessing system parameters. The following information is provided to
help you set all security parameters.
Prior to setting security passwords you will access the security menu by pressing the UTILITY button. Then use the

for the other password level if required. Since the security system has three levels (high, med and low), there can
TORE>-SAVE/<UTIL>-EXIT
be three different levels of user access. High level users always have full access to the box. Typically, the device
would be programmed to allow the medium level users minimal access, and the low level users very limited or
no access. However, if you simply require full access and no access, you do not need to set the medium level
password. Just make sure to set all of your Security Level functions to high, meaning one must be logged in as a
high level user to have any access to the processor’s parameters.
To now lock out the box you must log in as a low level access user (or essentially log out as a high level access
user). Follow this procedure to lock out the device:

6.2 ZC-Zone Controllers
ZONE CONTROLLER INSTALLATION
The installation of the Zone Controllers MUST be accomplished with the use of cable which is rated VW-1 or higher.
Common NEC designations which meet this rating include: CMP, CMR, CMG, CM and CMX.
The Zone Controllers offer additional utility to the DriveRack 260. They allow real-time adjustment of output levels,
mutes and program changes from simple wall panel interfaces. On the 260, a maximum number of six Zone Controllers
may be used and they may be nested, in other words, one controller may be used for a single zone and then another
controller may be used for the entire venue or system. With a maximum distance of up to 1000 ft. on CAT5 cable with
RJ-45 connectors, the Zone Controllers offer an easy to program and use remote control surface.
ZC REMOTE DESCRIPTION
The following describes the functions of each dbx ZC remote wall panel.
ZC-1
The ZC-1 is a programmable zone controller that allows output volume level control from a wall panel.
ZC-2
The ZC-2 is a programmable zone controller that allows output volume level and mute control from a wall panel.
ZC-3
The ZC-3 allows wall panel program selection for the 260.
ZC-4
The ZC-4 provides contact closure program selection for room combining applications.
ZC-BOB
The ZC-BOB allows parallel or home run cabling of the Zone Controllers.
PROGRAMMING
To be programmed, each Zone Controller must have its ID number set using the DIP switches on each ZC. The Zone
Controllers are programmed from the Utility Menu, which can be accessed either from the front panel of the DriveRack
260 or from DriveWare (the software GUI).
The diagrams on the following page show screen shots from the DriveWare GUI, as well as a description on how to
program each Zone Controller.

ZONE CONTROLLER WIRING
The DriveRack 260 Zone Controllers, (ZC-1, ZC-2, ZC-3, ZC-4) can be wired serially or in parallel. To wire in series each
Zone Controller must have an identification or zone number chosen using the DIP switches on the side of the controller
(see diagram A). Each controller must have a unique number chosen, although there may be multiple Zone Controllers
controlling a single zone, or a single Zone Controller that controls multiple outputs. The Zone Controllers can then be
wired together and connected to the DriveRack 260 (see diagram B).
The Zone Controllers may also be wired in parallel with the use of the ZC-BOB. To wire in parallel (home run cabling),
each controller must have a unique identification or number chosen using the DIP switches on the rear of the panel (see
diagram A). It is good practice to match the ID # of each ZC with the corresponding numbered port on the ZC-BOB. To
wire in parallel, each controller must be wired into a port of the ZC-BOB with a connecting wire going to the DriveRack
260 (see diagram C).

When connecting Zone Controllers, in series, the following cable length restrictions apply:
• If using a single ZC, the ZC may be connected directly to the DriveRack 260. The maximum cable length for a
single ZC connected to the DriveRack 260 cannot exceed 1000 feet.
• As shown in Diagram A, any (3) Zone Controllers may be wired in series as long as the total cable length does
not exceed 600 feet.
• Any (6) Zone Controllers may be wired in series as long as the total cable length does not exceed 300 feet. Refer
to Diagram B.
• Cable runs of up to 1,000 feet may be achieved using “Home Run” wiring. An example of this is shown in
Diagram C. A dbx Zone Controller Break Out Box (dbx ZC-BOB) is used to parallel several cable runs (up to
six).
Note: The preceding cable lengths were achieved using Cat5 Enhanced cable exhibiting a maximum D.C. resistance of
29 Ohms per 1,000 feet. Daisy chaining ZCs off the ZC-BOB is not recommended or supported.

A.4 Auto EQ Optimization Tips
By using the System Setup Wizard, crossover parameters, post-crossover parametric EQ and, in some cases, driver
alignment delay settings are set to match your system. The Auto EQ can be used to adjust your system to compensate
for room effects, and adjust the response of the entire system to your liking. After allowing Auto EQ to “pink the room”
your system will sound tighter. The low end will have more definition, the mids will be more intelligible, and the highs
can be tamed. Here are two things to look for to get the best performance from the Auto EQ.
Look out for Modes
Some speaker and RTA microphone positions will result in certain frequencies canceling out. The resulting modes can
not be corrected with equalization. The Auto EQ does not detect modes in the frequency response, so may try to boost
a band to compensate for a mode without positive affect. 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 re-pink the room for a more effectual Graphic EQ adjustment.
Adjust Crossover Output Gains (gain structure)
If your system setup or the response you have chosen results in the Auto EQ lifting or cutting a number of consecutive
bands of the Graphic EQ, you can adjust the level of the associated crossover output gain to match the average boost
or cut in the graphic EQ and re-pink your room. This time, the adjustment of the Graphic EQ bands will be less “heavy
handed” and the system will sound better having fewer phase problems and a lower noise floor than a more aggressively
adjusted Graphic EQ. With the rest of your system properly adjusted, the Auto EQ can compensate for room resonance
and adjust to suit personal taste without large excursions in the Graphic EQ bands.
Note: If using a ‘Custom’ configuration, meaning any of your amplifiers/and or speakers were not selectable in the
System Setup Wizard, it is recommend to properly tune some of the parameters within the DriveRack 260 before using
the Auto EQ feature. Failing to do so could yield undesirable results. Therefore, it is highly recommended that the
parameters contained in the following effect modules should be tuned in the DriveRack 260 before using the Auto EQ
feature:
• Crossover
• Output Limiters (including calibrating the systems gain structure - see section “A.10 System Setup and Gain
Structure”)
• Output PEQ(s), if applicable
• Output Delay(s) (driver alignment delay), if applicable

The DriveRack 260 gives you the option of changing the input gain level settings. There are 3 hardware configurable
gain settings. They are: +14 dBu, +22 dBu and +30 dBu. For these cases, use the following procedure to change the
gain level settings. Please be advised however, that once the gain level has been changed from the factory settings, the
output meters will no longer be calibrated correctly.

The DriveRack 260 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 260 we have included a Wizard setup tool to help in system setup. If you use the Wizard to set up your
DriveRack 260 it will automatically set the limiters for some amplifier selections. If your amplifiers are not available in
the Wizard, you should choose the Custom setting. The following section explains how to maximize system gain and
how to use the limiters to protect your amplifiers from clipping.
In traditional system design, the output of your console would be routed to a system EQ, a compressor, and a crossover
with output level control. From the crossover, there may be additional filters that are employed to improve the response
of your speakers. There may also be limiters set up to keep your amplifiers from going into clipping and protect your
speakers from the hazards of a clipped signal. Your amplifiers play a vital role in system setup, because they are last
item in the chain before your speakers and offer the greatest amount of gain (that is their job after all). If your amplifiers
are incorrectly setup you will not be using your system to its fullest potential and could be harming your speakers.
One thing that is critical to system setup is maximizing gain structure. Gain structure refers to aligning the gain of each
device so that they all clip at the same point, and the noise floor of the entire system is at its absolute minimum. Quite
often PA systems are setup with the amplifier input controls turned all the way up in the incorrect assumption that this
is the only way to get the maximum output level. Amplifiers are fixed gain devices, turning down the amplifier input

attenuators does not change the potential output of the amplifier; it only requires more input voltage to get full output
power. Many amplifiers will clip with an input level greater than +6 dBu when the input attenuators are turned all the
way up. Most mixing consoles can deliver over +18 dBu of output level before clipping. This means that with your amps
tuned all the way up you are sacrificing 12 dB of headroom, resulting in poorer noise performance and the potential of
system clipping. By adjusting the amplifier controls properly, you can maximize your system performance.
A way to set up your amplifiers for maximum gain structure is to use the clip indicators of the console and amplifiers
themselves. Disconnect the output of the amplifier from the speakers. Run a continuous signal (pink noise or sine
waves – many test CDs are available that have these types of signals) through your console. Turn up the output of the
console until it begins clipping. If there is no clip indicator on the console then use the output meters; most reputable
console manufacturers use red LEDs at the top of the meters to show the onset of clipping. Once the console is clipping,
back the output gain down slightly until the clip indicator turns off. Run this signal through the DriveRack 260 and into
the amplifiers with the crossovers and output gain section in the DriveRack 260 set for your particular speakers. Make
sure that the output limiters are turned off. Run this signal into the amplifiers and turn up the input attenuators until
the amplifier clip indicator begins to turn on. Turn the attenuators down slightly, so the clip indicator no longer is on.
You have just maximized the gain through your system. This amplifier setting should give you maximum gain without
clipping, another way of say this is that when the output of your console is clipping you will also be at the clip point of
your amplifiers.
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 260 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 260 and turn the limiter for each output band on. Make sure that the threshold is all the way up to +20dB.
Now slowly reduce the threshold until the clip indicator of the amplifier turns off. You have successfully set the output
limiter up and the amplifier will not be able to go into clipping no matter what the input is. You should now proceed to
the next output band and go through the same process. If you are using a sine wave to create clipping in your amplifier
you should make sure that the sine wave is within the frequency range of the output band that your are working
with. Once all the limiters are set up you can now turn the amplifiers back down to the gain maximized position. The
Wizard will automatically set your limiters based on your choice of amplifier. Because of component variances within
the amplifier circuitry, you may need to adjust the limiter settings by a few dB after running the Wizard to ensure that
they are set correctly. Once all the limiters are set up and the gain is maximized, reduce the output of your console and
reconnect your speakers. Now for the fun part, sit back and send your favorite music through the system. If your system
is not loud enough, you may want to consider an amplifier or amplifiers with greater output power. Most loudspeaker
manufacturers recommend an amplifier that can provide 1.5 to 2 times the rated RMS power of the speaker. If this setting
is too loud when your speakers are reconnected you can turn down the amplifier input attenuators even more.
