AFS
• The 260 DriveRack also offers its exclusive AFS (Advanced Feedback Suppression)
module which is located within the INSERT module section of select or user-created
configurations. This unique feature now makes unwanted feedback in a PA system a
thing of the past. The AFS Wizard will lead you through the setup of of the fixed fil-
ters of the AFS module. The fixed filter mode is designed to place notch filters as
you introduce feedback by opening up your mics and slowly increasing the gain.
Because the fixed mode is sensitive, it is important not to present an external music
source such as CD player or other audio signal into the system. From the Wizard
menu, rotate the <DATA> wheel until the display appears as follows:
• Press the <NEXT PG> button and the display will read:

• You will now use the <DATA> wheel to select the number of fixed filters. This will range from
values 0-12. The total number of filters will stay at 12, and the number of live filters will be =
Total Num Filters – Num Fixed. Live and Fixed filter types differ in that FIXED mode filters are
automatically assigned to a frequency creating feedback, thus remaining at that frequency until
cleared by the user. In LIVE mode, live filters automatically detect and remove feedback fre-
quencies in the presence of audio (music or speech). 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 frequen-
cies may change as the microphone is moved, and/or as the characteristics of the venue
change.

the <NEXT PG> and the display will read:
AB

• These types pertain to the Q, sensitivity, and algorithm type. The filter is established by using
the formula: Q= Freq divided by Bandwidth. This means that a higher Q will produce a fil-
ter that is more narrow. Values are: Speech (Bandwidth = 1/5 octave and Q=7.25) Music
Low (Narrow notch filter, Bandwidth = 1/10 octave and Q=14.5), Music Medium (Very
Narrow notch filter, Bandwidth = 1/20 octave and Q=29) Music High (Ultra Narrow notch fil-
ter, Bandwidth = 1/80 octave and Q=116). To guarantee that feedback is suppressed at
lower frequencies, the AFS may place wider notch filters at these lower frequencies (below
700 Hz). Once the desired fixed type has been selected, press the <NEXT PG> button and
the display will read:

gram index to a user program.
User Configuration is an ideal feature available in the 260 DriveRack. Even with the versatility
of the Factory 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 cus-
tom 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, Post-
crossover Parametric EQ, Dynamics, Post Delay, Output Gain and Phase. The following infor-
mation contain a standard block diagram of the signal path in the 260 DriveRack which can be
used as a reference map, as well as step-by-step instructions for creating custom user configu-
rations.

Section 4 Detailed Parameters DriveRack
The 260DriveRack 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 260 DriveRack.
4.1 Pre-Crossover EQ
The 260 DriveRack’s Pre-Crossover EQ section may be configured as a single or linkable 28
band graphic EQ or 9-Band PEQ.
GEQ
EQ On/Off
Turns the EQ on and off.
Flatten/Restore
This parameter either flattens the GEQ or restores the GEQ to the last setting before flattening.
The DriveRack unit allows you to leave the EQ edit window and return without losing the edit-
ed EQ settings.
PEQ
EQ On/Off
Turns the PEQ on and off.
Flat Set/Undo
This parameter either flattens (set) or restores (undo) all bands to their original settings.
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.
Level 9 -12 to 12 dB
Sets the overall gain of the high shelf parametric
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 updat-
ed 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 “Start w/ Data Wheel.” If Clear
(none) is selected, then nothing is displayed on this row. When the user moves to this third
row and turns the Data Wheel (when Clear Live or Clear All is selected) then the filter reset is
invoked.
Release 360 to 5 dB
Release sets the speed at which the gate “closes” or attenuates when the end of the Hold time
is reached.
AGC: On/Off
Turns the AGC module On and Off.
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
Notch On/Off
Turns the notch filters on and off.
Frequency (1 to 6) 20 to 20K
Selects the desired notch filter frequency of the selected notch filter.
Gain -36 to 6 dB
Sets the level of the selected notch filter. Set to +6dB to help find unwanted feedback, then set
to -3dB to -36dB to remove.
Q 16 to 128
Selects the Q of the selected notch filter.
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 260 DriveRack Crossover can be configured as
a 2x3, 4, 5, or 6. Appendix A.5 illustrates each of the available crossovers. The High-Pass or
Low-Pass filter being edited is indicated by the highlighted edge in the graphics area.
Frequency
Adjusts the frequency of the Low Pass filter from 20 to 20KHz.
Type
Selects the filter type. Selections are: BS 6, 12, 18, 24 Bessel type filter, BW 6,12,18,24 for
Butterworth type filter with slope of 6, 12, 18 or 24 dB/Octave and LR12, 24 for Linkwitz-
Riley type with slope of 12 or 24 dB/Octave.
Gain
Sets the level of the selected crossover band. Range is from Infinity to +20dB.
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.
Type
This parameter selects the PEQ type. Types include: 1. Bell-All parametrics are bell-shaped 2.
HShelf - One shelf is High, while all others are bell 3. LShelf - One shelf is Low, while all oth-
ers are bell and 4. LHShelf - One shelf is High and one is Low, and the others are bell.
Q (1-4) 0.20 to 16 dB
Sets the Q or Bandwidth of the selected Parametric EQ.
4.9 Compressor/Limiter
The 260 DriveRack also offers Compression and Limiter 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 such as vocals and guitars. The Limiters are located
on each output channel and have been strategically placed for speaker and amplifier protec-
tion. 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 fol-
lows and are user adjustable.
COMPRESSOR
Compressor On/Off
Turns the Compressor module on and off.
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 perfor-
mance from the unit. 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).
LIMITER
Limiter On/Off
Turns the Limiter module on and off.
®
Auto On/Off/
When auto is turned on the 260 will continuously set the attack / hold / release controls
itself.
PeakStop+ involves a two-stage process of dynamic limiting. The first stage of PeakStop+ is the
Instantaneous Transient Clamp™ which clamps the signal with a soft logarithmic clamp func-
tion. 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
®
Overshoot 1-6
This parameter sets the amount of overshoot for the Instantaneous Transient Clamp™.
Delay On/Off
Turns the Speaker Alignment delay on and off.
Length
Sets the amount of Speaker Alignment delay time. Delay times include: Seconds- 0.00-2.7 sec-
onds, Feet- 0.00-11.3 and Meters - 0.00-3.43. Fine adjustments are made in 20uS increments.
Coarse adjustments are made in 190 msec increments.

™
Section 4 Detailed Parameters DriveRack
Noise Level -10 to 10 (Mixer and Router)
Adjusts the overall level of the pink noise generator.
4.12 Output
The output section 480, 481 and 482 DriveRack™ units provide the user with the ability to con-
trol 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 compressor/limiters; this
means that the compressor/limiter directly affects the output level. The parameters for the
Phase Compensation effect are as follows and are user adjustable. Please refer to section A.9
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 level is
off, phase is 00 and polarity is positive.
Polarity On/Off
This parameter is used to reverse the polarity of the output signal.
Phase 0 to -1750
This parameter sets the amount of phase within the selected output path. The phase is refer-
enced to the upper frequency of the selected output crossover band.

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 5000 ft. on CAT5 cable
with RJ-45 connectors, the Zone Controllers offer an easy to program and use remote control
surface.
ZC-1
The ZC-1 is a programmable zone controller that allows volume level control from a wall panel.
ZC-2
The ZC-2 is a programmable zone controller that allows 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 identification set using the DIP switch-
es on the rear of the panel. The Zone Controllers are programmed from the Utility menus,
either from the front panel or from the GUI. To program, each Zone Controller is selected and
the outputs and functions are assigned. The ZC-1 allows output selection and Boost and Cut
level. The ZC-2 appears exactly the same as a ZC-1 in the Utility menu, but also allows output
muting as well as Boost and Cut.
The ZC-3 and ZC-4 allow program selection from either a wall panel, or contact closures. The
diagrams on the following page show screen shots from the GUI, a ZC-3 being programmed
with the selected programs and the panel that is assigned and a ZC-4 being programmed with
up to four contact switches and the program that each of these combinations of switches will
load.
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 cho-
sen using the DIP switches on the rear of the panel (see diagram A). 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).

A.1 Factory Reset
In the event that a reset is required, the DriveRack™ 260 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 program-
mable 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.

The 260 DriveRack 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.
To change the gain level, move the jumpers to the pins that are marked with the desired gain setting
1) First, make sure that the unit has been shut off and unplugged prior to opening the unit.
2) Ground yourself prior to opening the DriveRack™ chassis to prevent ESD damage.
3) Open the chassis by removing five screws on each side of the chassis and the top two center screws on the rear panel,
as well as the top center allen screw located on the front panel
4) Locate the jumper block shown in the illustration below:

Input Jumpers
In traditional system design, the output of your console would be routed to a system EQ, a com-
pressor, and a crossover with output level control. From the crossover, there may be addition-
al filters that are employed to improve the response of your speakers. There may also be lim
iters 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.
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 clip-
ping. 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 attenu-
ators 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 ampli-
fiers.
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 con-
sole. 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 con-
sider an amplifier or amplifiers with greater output power. Most loudspeaker manufacturers rec-
ommend 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.
