5.1.3 Dump Out PRESET T o download a PRESET : Use to reach the required PRESET . DIAL Press ENTER. Note: The menu page remains unchanged to allow other to be dumped. PRESETS All the Preset s data (name, configuration, parameter values, etc.) are immediately transmitted to the units connected to the serial ports (other , computers, etc.
5.2.Delay Menu Use this menu to work on the systems delay lines. The practical differences between and Delay 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.
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.
16 The values can be set in the following ranges: The values can be set in the following ranges: 5.3 Edit menu The values can be set in the following ranges: menu EDIT Input Gain Input EQ Xover Output EQ Output Gain Output Pol.
17 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. 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.
18 b. Centre Frequency / Cutoff Frequency Peaking Low Shelving High Shelving Notch c. Bandwidth Allows to choose the width in octaves of the Peaking or Notch type curve. It s not used with Shelving curves. Peaking Notch d. Gain Allows to control the boost or cut of the selected frequencies.
19 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 audio signal High, Mid & Low).
20 Each filter has the following editable parameters: T ype of filter Allows to choose three different types of filter and dif ferent 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.
21 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 .
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. The following editable parameters are available: b. Reaction times Allows to choose between 3 types of Limiter reaction speed.

b. Output Ganging Used to enable/disable Ganging function on the outputs. The settings are: 25 5.4.2 UNITS SUBMENU Used this submenu to choose the measurement units to be used with certain functions. a. Delay Unit Used to set the measurement units in which Delays are expressed (DELA Y menu).
26 5.4.3 Misc. Setup submenu Use this submenu to set a series of system options. a. Input Select Used to choose which MAXIDRIVE3.4 should use. inputs The options include: The inputs selected become and . Any signal on the inputs not selected is ignored.
27 c. T emperature Used to key in the value of the environmental temperature of place of installation. The system uses this value to automatically compensate for the differentials due to the dif ference speed of sound T ransmission according to the air temperature.
28 How to enable protection First of all, choose the protection mode: T wo modes are available: T otal: Partial: all editing functions are blocked and only the parameters relative to the Inputs access.
Note: in the event of an incorrect password, the display prompts again, encrypting all the characters again. Protection is unlocked and the system enters default status. 5.4.5 MEMOR Y CARD SUBMENU Allows to the Multimedia Memory Card. format The Card can't be used by the system.
