10.Input Level LEDs

The LEDs are used to indicate the level of input A/B. In order to get an up-front distortion-free signal, you keep the signal quite high, but do assure that the red CLIP LED doesn't light up continually.

11.Mute switches

There are six mute switches (1-6). They are used to mute the signal of the respective outputs. When the switch is on, the corresponding led will light up. These switches can avoid signal peaks when switching on and off the sound system and isolate the individual audio sections during testing or checking sound, etc.. The restored Mute function can be set to use the Wake Up Function (Utility menu Misc. Setup submenu) and can be set as Normal (last setting before the unit was switched off) or Mute (all outputs automatically forced into Mute status).

their

12.Output Level LEDs

These LEDs indicate the level of the respective outputs (you can adjust the output via adjusting the Output Gain parameter of Edit menu.)

Note: The LIMITER on any output will change the way in which the level is displayed on the corresponding LED. In fact, the level shown on the ladder is no longer the "absolute" output level, but the level of the signal at -24dB,

-12dB, -6dB compared to the limiter threshold (indicated by the orange LIMIT LED).

In this case, the two bypassed convention will improve the quality of the signal. A signal connected to the digital input has the same processing as that connected to analog input. The Digital/ Analog input selection can be set by using the Input Select function (Utility Menu-Misc. Setup Submenu).

16.RS485 OUT

This is the standard serial communication interface port. It allows outgoing communication between a MAXIDRIVE3.4 and PC or other MAXIDRIVE3.4 units. The RS485 interface is very suitable for remote control over long distances (difficult with RS232 standard ports) and daisy-chaining several MAXIDRIVE3.4.

17.RS485 IN

The function of the RS485 IN port is opposite to RS485 OUT. It allows incoming communication between a MAXIDRIVE3.4 and PC or other MAXIDRIVE3.4 units. The RS485 interface is very suitable for remote control over long distances (Difficult with RS232 standard ports) and for daisy-chaining several MAXIDRIVE3.4.

18.RS 232

This is the serial communication interface port. It allows incoming and outgoing communication between a MAXIDRIVE3.4 and a PC or other MAXIDRIVE3.4 units. Communication protocol includes:

-Remote control: 1). Connect the MAXIDRIVE3.4 to a PC; 2). It is possible to use the LTO editing software to control functions of all the processor remotely.

-Preset Dump: 1). Connect two MAXIDRIVE3.4; 2). It's possible to Dump the single Presets from one unit to another (refer to Dump procedure).

-Program Change commands send/receive: 1). Connect two DAXIDRIVE3.4; 2). When a Preset is recalled on the first one, it's possible to send a Program Change command to the second one to recall the same Preset number (refer to Load Preset procedure).

19.OUTPUTS

These (Outputs1~6) are balanced XLR-M connectors. The high quality, low noise, 20 bit converters can make A/D conversion.

20.INPUTS

INPUT A and INPUT B are compatible with balanced XLR and JACK. They are audio connectors of the respective sections. The high quality, low noise, 20 bit converters can make A/D conversion.

4. GETTING STARTED

The powerful versatile signal processor MAXIDRIVE3.4 is mainly designed for use with audio systems. Its routing

figurations of the input and output can be only set by recalling one of the PRESETS included in the internal memory. So the user must be very clear about the main function of the unit in order to get a best operation of your MAXIDRIVE3.4. Before you start your operation, please read the following parts carefully:

4.1 Configuration of the system

At first, switch off the equipment, carry out the audio and power connection from the various components of your

sound system.

Then, connect the main cord and only switch on the MAXIDRIVE3.4. The display will show the data regarding with the operating system release for a few seconds.

4.2 Adjusting the input signal

It is much more important to set the input signal of a digital unit than that of excessivelyan analog unit, because high input signals will make particularly distinct noise (highany saturation of the A/D converters cause a typical level square wave).

Proceed as follows:

Keep the MAXIDRIVE3.4 outputs in status (LEDs light on).MUTE

MAXIDRIVE3.4'sFeed a signal in on the input and watch the LED ladders.INPUT LEVEL A-B

To obtain a good signal/noise ratio, i.e. an up-front distortion-free signal, keep the signal quite high, but make

certain the red CLIP LED doesn't light up continually.

Find out the output level setting for your mixer (or other unit) and connect it to the input of the MAXIDRIVE3.4.

4.3 First Setup

At this point, the first custom setup can be prepared. The following is only the description of setup procedure. The detailed specifications of each parameter are shown in the respective paragraphs of the manual.

Firstly, set the following parameters in order:shown

Output Pol. Polarity of the outputs Xover Crossover frequencies (separation of the speaker channels) Output Delay Alignment of the speaker enclosure components Output Gain Levels of the outputs

Note: The regulation of the MAXIDRIVE3.4's parameters is closely related to the characteristics of the com-

ponents of the sound system. So if you're not the expert, please refer to the documentation and technical specifications of your power amplifiers, loudspeaker enclosures, monitors, etc.. This will enable you to work faster and safely.

(if you have the necessary equipment) and any corrections required.

Then, if necessary, adjust the values of the following functions:

Output EQ Output equalizers Output Limiter Output limiters

Note: In this first phase of setting up your sound system, the adjustment of these functions (which if not Indis

-pensable during installation) can wait. But do remember that adjusting the equalizers can also affect the signal level. So if considerable equalization changes are made, remember to check and adjust the output levels too, if necessary.

This indicates that the value of one or more parameters has been temporarily modified with respect to the stored in the PRESET shown. Practically speaking, this indication means that the changes made to the PRESET have not been stored.

Note: once it has been enabled, the indication remains even if the "original" values are reset manually.

The indication disappears as soon as the PRESET is saved or as soon as a new PRESET is loaded (including this same PRESET).

In other words, the indication disappears as soon as stored values are accessed. If the PRESET isn't saved, temporary changes are lost as soon as a new PRESET is loaded (including this same PRESET).

Note: temporary changes are kept on the other hand in the "buffer memory": when the unit is switched on, the system maintains exactly the same settings as when the unit was switched off, including temporary changes.

4.9.System Protection

These indications appear when the function ( menu) is enabled, i.e. when the system is totally ( )LOCK UTILITY T or partially ( ) protected against accidental or unauthorized changes (even if temporary).P Protection is ensured by a , without which editing procedure can't be unlocked.password

The practical differences between andDelay Input Delay Output

A Delay is only a processor by means of which a signal is deliberately delayed by a programmable length of time. From a technical point of view, the Delays applied to the inputs and outputs are equivalent. Nevertheless, their application is different:

Parameters

Input Delay

DELAY

OUTPUT DELAY

INPUT DELAY

delays the signal of an input (or the sum of the inputs) before sending it to the routing system. In this way, all the outputs which depend on that input are delayed by the same length of time.

Also called input Delay is mainly used to compensate for the effectsMaster Delay, dues to the distance between the various speaker enclosures or between various blocks of a complex sound system (for example in large concert halls, stadiums, etc.), Thus achieving virtual alignment.

Output Delay only delays the signal of a specific output.

Also called Channel Delay, output delay is mainly used to compensate for the distance between different blocks of the same sound system (for example clusters) or to correct internal alignment of a speaker enclosure components.

Parameters

In these pages, the number of the parameters and how they are presented varies according to the configuration of the PRESET and according to and settings ( menu). In fact, theseGanging Units UTILITY pages only show the parameters that can actually be used, in the most suitable form of editing.

5.3.1 Input Gain

Input gain control.

Input Gain

Allows to adjust the amplification of the signal fed in through Inputs A and B. Editing values are in the range +6dB ~ -30dB, with 0.5dB steps.

GA I N

-2.5dB

Note: Setting the input signal of a digital unit is particularly important, much more than on an analog unit, as

any saturation of the A/D converter due to an excessively high input signal causes a typical particularly distinct noise. To achieve a good signal/noise ratio, i.e. an up-front distortion free signal, feed a signal in on the MAXIDRIVE3.4's input and watch the LED ladders. Keep the signal quite hINPUT LEVEL A-B igh, but make certain

the red LED doesn't light onCLIP continually.

5.3.2 Input EQ

Input equalizer with 5 parametric filters.

Allows to alter the overall tone of the signal connected to the respective input. Also called the equalization of the input signal effects all the outputs connected to theMaster EQ, input and the input SUM. This component's characteristic quality and programmability (identical to the output Equalizer) enable it to be Used so effectively and flexibly as to make the use of graphic equalizers often unnecessary.

Input EQ

Each equalizer has 5 pages (one for each filter), showing the name of the input it affects and the number of the filter.

The following editable parameters are available for each filter:

a. Type of filter

Allows to choose among Peaking, Low or High Shelving with a slope of 6 or 12 dB per octave and Notch filter.

The values can be set in the following ranges:

5.3.3 Xover

Low-pass and high-pass filters. Made up of a combination of a low-pass filter and high-pass filter, the crossover allows to divide the into segments that can be used by the individual section of a sound system (for example

Xover

High, Mid & Low).

Each Xover has 2 slightly different pages (one for each filter), where the name of the output it affects and the type of filter are shown.

00Hz

Output1-LowPassFilter

Low Pass Filter

The low-pass filter allows all the frequencies below a specific frequency to pass, whereas it cuts all the frequencies above it.

Signal segment obtained with the combination of LPF and HPF.

Each filter has the following editable parameters:

Type of filter

Allows to choose three different types of filter and different attenuation slopes:

Butterworth (But) at 6, 12, 18 or 24dB per octave, Bessel (Bes) at 12, 18 or 24dB per octave, Linkwitz-Riley (LR) a 12, 24 or 48dB per octave.

By setting the value, the filter is disabled and the signal passes without its frequency being alThru tered.

Crossover frequency

Allows to choose the filter cutoff frequency.

46 zH

Phase

Allows fine control (in 5 steps) of the signal's phase. The effect of this control is summed with that of the Output Polarity function (0 ~ 180 ). In this way it's possible to adjust the phase of each individual output with 5 steps through a full 360 .

Note: this control is only in the Low-Pass Filter window.

5.3.4 Output EQ

Output equalizer with 5 parametric filters.

Also called Channel EQ, allows to alter the tone of each individual output. The characteristics of quality and programmability are identical to those of the Input Equalizer and enable this unit to be used extremely effectively and flexibly.

Out pu t EQ

Each equalizer has 5 pages (one per filter), indicating the name of the output it effects and the number of the filter.

00 1

Since technical specifications and editing fields of the Output EQ are identical to those of the Input EQ, please refer to INPUT EQ section for descriptions.

5.3.5 Output Gain

Output level control Allows to adjust the signal level of each individual output.

+1 . 5

Example: Output 1 - Filter 1

Out pu t Ga i n

Editing values are between +6dB ~ -30dB, with 0.5dB steps.

GA I N

-6.5

Note: The level of each output is shown by the respective OUTPUT LEVEL LED ladder. To avoid distortion, don't

let the red CLIP LED light up. As automatic protection, you can also enable the LIMITER (EDIT menu) on the outputs that require it. In this case, remember that enabling the LIMITER changes the display mode on the level, but the level ofrelative LED ladder: in fact, the level shown is no longer the absolute output the signal In relation to the LIMITER threshold.

5.3.6 Output Pol

Controls the output's polarity. Allows to invert the phase of the signal of individual outputs.

Out pu t Po l

Editing values are:

Normal: leaves the phase unchanged

Reverse: shifts the phase through 180 , inverting it.

The effect of this control is summed with that of the parameter of the filter ( menu), whichLPF Xover - EDIT operates with 5 steps in a range of between 0 and 180 . In this way it's possible to set the phase of each individual output with 5 steps within a complete 360 revolution, a very useful function when assembling arrays of speaker enclosures, in the control of the interpolation between various enclosures or between sections of the same system.

5.3.7 Output Limiter

a. Output level limiter

Allows to keep the signal of each individual output within a set level. Can be used effectively to protect the components of a sound system.

Allows to choose between 3 types of Limiter reaction speed. In fact, these are attack and release times that are optimised so that the Limiter reacts more or less rapidly when the signal exceeds or drops below the threshold:

Fast

Normal

Slow

c. Threshold

Allow to set the level above which the Limiter intervenes (limiting the signal) and below which it leaves the signal unchanged.

The editing values are within the following ranges: +19.8dBu ~ -10dBu, with 0.2dBu steps

The measurement unit can be chosen with the Lim. Thresh. Unit function ( menu submenu).UTILITY - Units The Off value disables the LIMITER, whereas any other value enables it.

5.4.1 GANGING SUBMENU

Ganging Input Ganging

Output Ganging

This submenu allows to group together the treatment of similar inputs and/or outputs. Similar is intended as meaning elements which have the same properties and/or the same structure. For example, the right and left sections of a stereo system are similar, as they are made up symmetrically of the same quantity and type of elements (the same components for High, Mid and Low frequencies).

Gang i ng

The practical use of the Ganging function consists in the possibility of editing with identical values the parameters of similar elements, carrying out single (instead of double) operations.

For example, it's possible to set the same Delay value or equalization on both inputs with just one operation; or set identical Xover parameters for the various outputs fed to a stereo sound system; or yet again, enable the LIMITER simultaneously on the two outputs dedicated to two mono stage monitors.

The system automatically recognizes incompatible elements contained in the various configurations and only enables the Ganging function where it can effectively be used. Therefore, the Ganging function doesn't have any effect on the MONO setups. The Ganging function can be enabled separately for both groups of input and groups of outputs.

IMPORTANT: Precisely for its characteristics, the Ganging function affects the way in which the relative parameters audio are edited or represented: As soon as Inputs and/or Outputs are ganged, the various menu pages only show the values that can actually be used. This however doesn't mean that the values change immediately. On the contrary, the values remain unchanged (Even if not shown) until new values are entered. Only at that point ganged, Inputs and/or Outputs assume the same value with the just one operation.

For example, even if the display shows that "Input A&B" are ganged in the page with a certain parameter, the value shown remains that of Input A until a new value is entered, as Input B doesn't automatically assume the values of Input A.

To check this:

1. set Input Gangin=Off, load the *Default* PRESET, set INA Delay=1 and INB Delay=0;

2. set Input Gangin=On, return to the Input Delay menu: the display shows INA&B Delay=1:

a. if you leave the value unchanged and once again set Input Gangin=Off

going back to the Input Delay menu, the display shows INA Delay=1 and INB Delay=0 ("original" values).

b. if you change the value, for example INA&B Delay=3, and you once again set Input Gangin=Off

going back to the Input Delay menu, the display shows INA Delay=3 and INB Delay=3 ("new" values).

This condition is used to avoid accidental or temporary enabling of the Ganging function from changing the values of all the stored PRESET. The rule can be summed up as follows: "only the values that have to be intentionally changed are changed".

So generally speaking, to avoid contradictions, oversights and confusion between what is shown and what is effectively carried out, it s advisable to enable the Ganging functions before starting to edit a PRESET. Moreover, it s best to make certain to effectively set the required value, manually confirming all the parameters required.

Note: The elements in Ganging assume the "new" value as soon as the DIAL changes the status of the "old " value. So, if the value which has to be allocated to the elements in Ganging is the same as the old value, it's necessary to use the DIAL, temporarily change the value (even only by one step) and then go back to the "old" value.
