DriveRack™ User Manual

The Configuring section of the 480, 481, 442 and 482 DriveRack™ units 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 480, 481 and 482 DriveRack™ units.

The first step in understanding the complex programming capabilities of the DriveRack™ is to understand the elements involved that combined, define 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. From this point, the 480, 481, 442 and 482 DriveRack™ units give you the option of entering subsequent levels of operation that are dedicated to program editing. The levels include: Configuration mode and Effect Edit mode. The key element to remember is that all of these components combined, make up the conventional “program”, and that they are all unique to each individual program. The utility menu mode and Network setup and management and setup are accessed via the utility menu, and are not part of the program.

From the factory, the 480, 481, 442 and 482 DriveRack™ units are shipped with 20 factory programs that utilize carefully constructed routing configurations that have been designed to accommodate virtually any sound reinforcement and installation application. These configurations are laid out in an intuitive straight forward manner on the 480. The 480 display shows the entire signal route from the input section to the output section.

Selecting Programs:

The quickest mode for getting up and running with the DriveRack™ is to simply use any one of the factory programs that are available in the box. To select a factory program, (from program mode), use the PARAMETER 1 knob to scroll through the various factory programs. This is an ideal method of selection because when each factory program is scrolled to, the display will clearly indicate the routing matrix, as well as all of the effects that are being used for the selected program. Once a program is selected, press the PROGRAM/CONFIG button to load the program. The display will appear something like this:

Input in a manner that will accommodate your application. The inputs of the DriveRack™ units can also mix audio from any one, or all of the analog inputs. Options for selecting and numbering Inputs include: Input names 1-4 and M.

3.5- B Pre Crossover EQ

At the pre crossover section of the signal path, the DriveRack™ units give you the option of utilizing either a 31 band graphic or 9 band parametric EQ on each channel of the selected input. The DriveRack™ will also accommodate a dual 31 band graphic EQ, dual (Show and House) 31 band graphic, or 9 band graphic EQs on each input. Enter the Configuration creation section of the DriveRack™ by pressing and holding the PROGRAM/CONFIG button. Now use the PARAMETER 2 and 3 knobs to move to the selected input of the pre-crossover EQ section. Once you are there, use the PARAMETER 1 knob to select either the 31 band graphic (G), Show/House (SH) 31 band, or the 9 band parametric (P) equalizer. In addition to the equalizers available in this section, inputs 3 and 4 offer real time audio analyzers which can be selected by using the same procedure.

3.5- C Notch Filter

At the Notch filter section of the signal path, the DriveRack™ units give you the ability to use a 1-5 band notch filter on any input within the section, while not exceeding 10 bands within the unit. The notch filter is the perfect tool for removing unwanted frequencies from the signal path. Enter the Configuration creation section of the DriveRack™ by pressing and holding the PROGRAM/CONFIG button. Now use the PARAMETER 2 and 3 knobs to move to the selected input of Notch filter section. Once you are there, use the PARAMETER 1 knob to select the desired Notch filter.

3.5- D Delay Section

The DriveRack™ units offer two unique delay sections within the signal path. The first Delay section can be used for setting overall room delay settings. Enter the Configuration creation section of the DriveRack™ by pressing and holding the PROGRAM/CONFIG button. Now use the PARAMETER 2 and 3 knobs to move to the selected input of Delay section.

3.5- E Crossover

The Crossover section of the DriveRack™ unit offers 27 different crossover options that can accommodate any audio application. Enter the Configuration creation section of the DriveRack by pressing and holding the PROGRAM/CONFIG button. Now use the PARAMETER 2 and 3 knobs to move to the Crossover section. Once you are there, use the PARAMETER 1 knob to select the desired Crossover module. Section 3.7 provides you with in-depth information for selecting and moving crossover types.

3.5- F Post Crossover Parametric EQ

After the Crossover section, the DriveRack™ units offer an additional 4 band Parametric EQ module. This EQ is often used to compensate for non-lineararities in speaker response. Enter the Configuration creation section of the DriveRack™ by pressing and holding the PRO- GRAM/CONFIG button. Now use the PARAMETER 2 and 3 knobs to move to the selected output EQ section.

METER 2 and 3 knobs to move to the selected output Delay section.

3.5- I Output Routing and Phase Compensation

From the Configuration creation mode, the DriveRack™ gives you the option of routing any digital output to any of the eight analog outputs of the DriveRack™ unit. This means that the digital output signal can be routed to any one of the eight physical outputs. Options for numbering Outputs names include: 1-8 . This means that two signals that are sent to the same output, will be summed to one output that shares the same name. In addition to output routing, each output section of the DriveRack™ unit offers phase compensation within the selected output module.

The DriveRack™ provides the user with an option to link like modules together (ie; four 31 band Graphic EQs and so on) so that when a change is made in a selected program to one module, the change will affect all of the like modules. This linking feature can be applied to every module used in any single configuration. The following procedure will illustrate how to perform this feature.

• While you are in Configuration mode, use the PARAMETER 2 and 3 to scroll to the mod- ule section that you wish to link. For this example, we will use the Graphic (G) EQ modules. Once a single Graphic EQ module has been selected, you can select all of the Graphic EQ modules by pressing the PARAMETER 3 knob, and the display will appear something like this:

• At this point, rotate the PARAMETER 3 knob to select all four Graphic EQ modules, then press the PARAMETER 2 knob to link the modules together. Once this has been done,

The 480, 481, 442 and 482 DriveRack™ units also offer compressing or limiting capabilities. Furthermore, within the configuration menu, compression or limiting can be assigned to similar bands (ie: highs with highs or lows with lows), or used in a full range capacity within the selected crossover. The parameters for the Compressor/Limiter are as follows and are user adjustable:

Compressor On/Off

Turns the compressor/limiter module on and off.

Peakstop+ On/Off

This parameter turns the peakstop limiting on and off. When peakstop+ is enabled, the ratio is automatically changed to ∞ :1.

OverEasy 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 right 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. 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. This 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 most OverEasy®). This lets you choose the exact knee that is needed for the dynamic effect you are looking for.

Threshold -40 to +20dBu

Threshold is the signal level at which the 480, 481, 442 and 482 DriveRack™ units start 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 1.0 to Inf:1

Ratio is the amount the 480, 481, 442 and 482 DriveRack™ units reduce 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 480, 481, 442 and 482 DriveRack™ units will compress the signal, and outputs a signal that only goes 1dB over the threshold. For light compression choose a lower ratio, while a heavy compression requires a higher ratio. A setting of Inf:1 sets the compressor act as a limiter, and engages peakstop+ if turned on.

Gain -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 was.

The 480, 481, 442 and 482 DriveRack™ units also offer a speaker alignment delay which is ideal to use for compensating signal delay that occurs between speaker driver components such as speaker clusters or between internal speaker components such as horns, speakers and subwoofers within speaker cabinet. The Speaker alignment delay is also ideal for compensation the difference in that high and low frequencies travel. The parameters for the Speaker Alignment Delay are as follows and are user adjustable:

Delay On/Off

Turns the Speaker Alignment delay on and off.

Units - Seconds, Feet or Meters

Selects the unit of measurement for the delay.

Length

Sets the amount of Speaker Alignment delay time. Delay times include: Seconds- 0-170.64ms, Feet- 0-192.32 and Meters - 0.0-58.5. Seconds- 0-341.32 for the 442, Feet- 0-384.66 for the 442 and Meters - 0-117.08 for the 442). Fine adjustments are made in 10ms increments.

The Network Function section of this manual will provide you with detailed information for establishing and maintaining a communication network between the 480, 481, 482, 442 and 480R DriveRacks™, and a PC, via the GUI interface by utilizing an RS-485 network standard protocol through a back bone system. Use this section to optimize communication performance between networked DriveRacks™.

Network Overview

The following illustration shows the versatility of a DriveRack™ network system. Notice that the DriveRack™ can be controlled by the GUI interface, 480R and the 480. This provides triple redundancy unit protection because information is continually being sent to all three controllers simultaneously. Also take note that the 480R can receive MIDI AFL cue information from selected mixing consoles.

Recommended Cable Specifications:

Essentially, any product in the DriveRack™ system offers several different options of communicating in a network system. From the factory, all DriveRack™ products ship with a single 1foot DB-9 network cable. The following applications utilize the following cable recommendations:

PC GUI Interface - DB-9 female-to-female nul modem cable. 480R and 480P - DB-9 male-to-male cable. The 480P also supports RJ-45 cables. RS485 Network (DB-9 type) - DB-9 male-to-male cable. RS485 Network (RJ-45 type) - RJ-45 cable.

Network cables are CAT-5 UTP 24 gauge.

Cable Lengths

480R to 480P - 250 feet max. 500 feet with dbx proprietary cable. 480P to Network - Up to 4000 feet. RS 232 PC to any slave unit - Max. 50 feet. MAXIMUM BACKBONE CABLE LENGTH - 4000 feet.

Please See Section A.11 for Wire Diagram Information

Connectors:

Every product in the DriveRack™ line feature both DB-9 and RJ-45 type connectors for establishing a network system. Both connector types are offered for added convenience to the user. DB-9 connectors are however used exclusively for interfacing with a PC. The following illustration shows the typical network rear-panel connectors for the 480, 481, 442 and 482 DriveRack™ units. You can utilize either connector type on a single unit. However, you cannot use both input or thru connectors simultaneously.

In addition to the rear panel network connectors, the 481, 482 and 442 offer PC GUI interface DB-9 type male connectors on the front panel.

DriveWare System Control GUI

System Control is a feature that will allow you to group multiple inputs and outputs together, and control them with one set of controls. Any input of any Driverack unit used in a network setup can be assigned to the System Control Input Group. By assigning inputs to the System Control Input Group, these inputs are then linked together and their Graphic EQs can

7.8 DriveRack System Control

Network Functions

SECTION 7

DriveRack

™

DriveRack™ User Manual

Network Functions

SECTION 7

™

be controlled simultaneously. In addition, an offset delay can be added to the System Control Input Group. Any output of any Driverack unit used in a network setup can be assigned to the 32 System Control Output Groups. An output can be assigned to more than one group. By assigning outputs to the System Control Output Group, those outputs are then linked together and their Delay offset, Output Level offset and Mute can be controlled simultaneously.

As an example of how you assign the outputs, you can make output groups called: HIGH, MID, LOW, SUB, MAIN, DELAY TOWERS, and ALL. You would assign all the high frequency driver outputs to the HIGH group. Similarly, assign the mid, low and sub outputs. All outputs associated with the main outputs are assigned to the MAIN group. All outputs associated with the delay towers are assigned to the DELAY TOWER groups. Finally, all outputs are assigned to the ALL group. With this configuration you can adjust the levels of the low, mid, high and sub outputs relative to one another. You can also adjust the level and delay between the delay and main towers relative to one another, and ultimately, have control over all outputs.

DriveWare allows configuration and parameter editing for System Control. The following gives a brief explanation of the System Control elements within DriveWare.
