Safety precautions

Information regarding use of loudspeakers

WARNING! Never stand in the immediate vicinity of loudspeakers driven at a high

level. Professional loudspeaker systems are capable of causing a

sound pressure level detrimental to human health. Seemingly non-

critical sound levels (from approx. 95 dB-SPL) can cause hearing

damage if people are exposed to it over a long period.

In order to prevent accidents when deploying loudspeakers on the

ground or when flown, please take note of the following:

When setting up the loudspeakers or loudspeaker stands, make sure

they are standing on a firm surface. If you place several systems on

top of one another, use straps to secure them against movement.

Only use accessories which have been tested and approved by d&b

for assembly and mobile deployment. Pay attention to the correct

application and maximum load capacity of the accessories as detailed

in our specific "Mounting instructions" or in our "Flying system and

rigging manuals".

Ensure that all additional hardware, fixings and fasteners used for

installation or mobile deployment are of an appropriate size and load

safety factor. Pay attention to the manufacturers' instructions and to

the relevant safety guidelines.

Regularly check the loudspeaker housings and accessories for visible

signs of wear and tear and replace them when necessary.

Regularly check all load bearing bolts in the mounting devices.

CAUTION! Loudspeakers produce a static magnetic field even if they are not

connected or are not in use. Therefore make sure when erecting and

transporting loudspeakers that they are nowhere near equipment and

objects which may be impaired or damaged by an external magnetic

field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic

data carriers (floppy disks, audio and video tapes, bank cards, etc.) is

sufficient; a distance of more than 1 m (3 ft) may be necessary with

computer and video monitors.

MAX Manual (5.1 EN) Safety precautions - 1

MAX

MAX loudspeaker

MAX is a 2-way floor monitor employing a 15“/2“ coaxial driver

combination with a passive crossover. The driver design allows the use

of a compact, low height cabinet. MAX can be driven actively or

passively.

Coaxially mounting the 2“ HF and 15“ LF drivers creates a very

compact single driver whilst retaining the benefits of separate magnetic

assemblies. The drivers are positioned together to utilize the combined

shape and geometry of the LF cone and HF horn to create a single

waveguide with a controlled, symmetrical 60° conical dispersion.

The MAX cabinet is constructed from marine plywood and has an

impact resistant paint finish. The front of the loudspeaker cabinet is fitted

with a rigid metal grill covered with a replaceable acoustically

transparent foam. A socket to accept a loudspeaker stand, a ratchet

strap kelping bar and optional MAN CF4 stud plate rigging points

complete the possible rigging options for MAX.

NOTICE: Only operate MAX cabinets with a correctly configured d&b amplifier,

otherwise there is a risk of damaging the loudspeaker components.

As an alternative other high quality power amplifiers may be used,

provided their output power does not exceed 500 Watts into 8 ohms

and an additional subsonic filter is used (25 Hz with 12 dB/octave

minimum), otherwise there is a risk of damaging the loudspeaker

components.

Connections

The MAX cabinet is fitted with two EP5 connectors. All pins of both

connectors are wired in parallel.

Using one connector as the input, the second connector allows for direct

connection to additional cabinets.

The MAX cabinet can be supplied with NL4 output connectors as an

option.

Pin equivalents of EP5 and NL4 connectors are listed in the table below.

Operating modes

4-wire operation (standard wiring EP5 and NL4)

Connector wiring

(4-wire operation with EP5 connectors)

The MAX cabinet is driven by a 4-wire cable to allow the choice of

active or passive operation. The HF and LF drivers are each fed by their

own pair of pins and separate passive crossovers. Pin assignments 1/2

of the EP5 connectors (NL4: 1+/1–) connect the LF driver, pins 3/4

(2+/2–) connect the HF driver, as shown in the diagram opposite.

2-wire operation (NL4 only)

Fig. 1: MAX 2-wire operation NL4

Fig. 2: MAX 4-wire operation NL4

For applications requiring dedicated passive use, the MAX cabinet’s

internal wiring can be configured for connection to pins 1+/1– of the

NL4 connectors allowing use of a 2-wire cable.

In the 2-wire/passive configuration both the LF and HF drivers are

connected to pins 1+/1– of the NL4 connector. Note that only the HF

driver wiring (white and white/red) differs from that used in the 4-wire

version.

The passive 2-wire configuration can also be used when the MAX

cabinet is combined with a d&b active subwoofer and driven through a

single 4-wire cable.

In the 2-wire configuration MAX can also be used with amplifiers from

other manufacturers. The output connector of the amplifier or signal

distribution box should feed the positive signal to pin 1+ and the

negative signal to pin 1– of the cabinet’s NL4 connector.

Modification

Tools required: 2.5 mm Allen key

1. Undo the four Allen screws of the connector plate.

2. Take off the connector plate.

3. Change the wiring on the back of the connector plate to the

desired configuration as shown in the illustrations opposite (1

and 2).

4. Refit the connector plate.

Operation with D6 or D12

Select the controller setup MAX.

MAX cabinets can also be operated with the LINEAR setup of D12 and

E-PAC amplifiers. However, the MAX setup provides low-end

equalization and limiter settings specially tuned for MAX cabinets used

as stage monitors thus providing improved performance and headroom.

Note: When MAX cabinets are used as downfills or frontfills for C4 systems,

passive operation is recommended. In Active mode the phase response

of MAX cabinets is not compatible with C4 systems.

Operation with D6

Up to a total of two MAX loudspeakers can be passively driven by each

D6 amplifier channel.

Operation with D12

The D12 allows the MAX cabinet to be driven either in "2-Way Active"

mode or in passive mode.

D12 Input/Output routing "2-Way Active"

Selecting "2-Way Active" mode with the MAX setup enables up to two

MAX cabinets to be actively driven by the D12 amplifier. In applications

with low continuous levels and low ambient temperatures up to three

cabinets may be connected.

In "2-Way Active" mode the D12 routes separate LF and HF signals to

the amplifier channels. Pins 1/2 of both EP5 output connectors (NL4:

1+/1–) carry the LF signal, pins 3/4 (2+/2–) carry the HF signal. The

output connector pin assignment is changed automatically when "2-

Way Active" mode is selected.

The input signal can be fed either to INPUT A or to INPUT B and is

routed (linked) to both amplifier channels internally.

respective channel. In applications with low continuous levels and low

ambient temperatures up to three cabinets per channel may be

connected.

Passive operation ("Dual channel" mode)

In "Dual channel" mode, the MAX cabinet can be used in either 4-wire

or 2-wire operation. The respective channel has to be set to MAX. Each

amplifier drives all output pins on the channel's output connector. Pins

1/3 of the EP5 output connector (NL4: 1+/2+) carry the positive and

pins 2/4 (1–/2–) carry the negative components of the signal.

Passive operation ("Mix TOP/SUB" mode - NL4 only)

In "Mix TOP/SUB" mode, the MAX cabinet has to be configured for 2-

wire operation.

Selecting the MAX setup mode for channel A and an applicable

subwoofer for channel B allows a single D12 to drive two MAX and two

active subwoofer cabinets.

When the D12 is operated in "Mix TOP/SUB" mode, the MAX cabinet

and a respective active subwoofer can be linked together locally and

fed by a single 4-wire cable from either amplifier output connector.

Note: To apply SenseDrive for the subwoofer, EP5 connectors and 5-wire

cables have to be used. When operated in "Mix TOP/SUB" mode, the

subwoofer has to be fed from the output B connector of the D12

amplifier.

Controller settings

For acoustic adjustment the settings CUT, HFA and CPL can be selected.

CUT

Set to CUT, a high pass filter with a 130 Hz cut off frequency is inserted

in the controller signal path. The MAX is now configured for use with

d&b active subwoofers.

Frequency response of HFA circuit

In HFA mode (High Frequency Attenuation), the HF response of the

MAX is rolled off. The HFA circuit provides a natural, balanced

frequency response when a unit is placed close to listeners in near field

or delay use.

High frequency attenuation begins gradually at 1 kHz, dropping by

approximately 3 dB at 10 kHz. This roll off mimics the decline in

frequency response experienced when listening to a system from a

distance in a typically reverberant room or auditorium.

CPL circuit

Frequency response of CPL circuit

The CPL (Coupling) circuit compensates for coupling effects between the

cabinets when building closely coupled arrays. CPL begins gradually at

1 kHz, with maximum attenuation below 400 Hz, providing a balanced

frequency response when the MAX cabinet is used in arrays of two or

more. The function of the CPL circuit is shown in the diagram opposite

and can be set in dB attenuation values between –9 and 0, or a positive

CPL value which creates an adjustable low frequency boost around

65 Hz (0 to +5 dB).

Operation with E-PAC

E-PAC version 1, E-PAC version 2

E-PAC configuration for “Linear” mode

To drive MAX cabinets, select the MAX or LINEAR setup.

E-PACs version 1 or 2 only provide the Linear setup. The configuration

is set by the appropriate DIP switches on the rear panel.

In LINEAR mode all four pins on the NL4 connector are driven by the

E-PAC power amplifier, pins 1+ and 2+ carry positive signal, 1– and 2–

carry negative signal. The MAX cabinet can be used in either 4-wire or

2-wire configuration.

For an E-PAC version 3, the configuration is set via the encoder in

conjunction with an LCD.

The E-PAC allows to drive one MAX loudspeaker. LO IMP mode

configures the E-PAC to drive a maximum of two MAX loudspeakers

with a 6 dB reduction in input level to the loudspeakers.

The CUT and HFA settings are available on E-PAC versions 2 and 3. The

characteristics of the CUT and HFA settings are explained in the

previous section "Operation with D6 or D12 - Controller settings".

MAX Manual (5.1 EN) Page 8 of 12

Operation with P1200A and ampMAX module

The combination of P1200A and ampMAX allows the MAX cabinet to

be driven either in "2-Way Active" mode or in Passive mode.

Controls on ampMAX module

2-WAY ACTIVE switch

The "2-Way Active" operation is described in the previous section

"Operation with D12 - "2-Way Active" operation”.

If "2-Way Active" is selected, the left volume control (CH A / ACTIVE)

controls both channels and sets the overall level while the right volume

control (CH B / HF-LEVEL) sets the relative HF level.

CUT switch

The CUT setting is available. The characteristics of the CUT setting are

explained in the previous section "Operation with D6 or D12 -

Controller settings". In active mode only the channel A CUT switch is

functional.

LFC switch

When the MAX cabinet is used without an active subwoofer, selecting

LFC (Low Frequency Compensation) extends the low frequency response

of the MAX cabinet down to 75 Hz. In active mode only the channel A

LFC switch is functional.

associated amplifier channel.

Up to two MAX cabinets per channel can be driven in passive mode.

Operation with P1200A and AMP-L module (NL4 only)

Controls on AMP-L module

The AMP-L module provides a single linear amplifier channel, which

drives the pins 1+/1– of the respective NL4 output connector. For

operation with the AMP-L module the MAX cabinets has to be

configured for 2-wire operation (see previous section "2-wire

operation").

A P1200A mainframe fitted with two AMP-L modules can drive two

MAX cabinets per channel in passive mode. Fitting one AMP-L and one

subwoofer controller module allows a single mainframe to drive two

MAX and two active subwoofer cabinets. All cabinets can be linked

together locally and fed by a single 4-wire cable from either mainframe

output connector.

CUT switch

The CUT setting is available. The characteristics of the CUT setting are

explained in the previous section "Operation with D6 or D12 -

Controller settings".

MAX Manual (5.1 EN) Page 9 of 12

Dispersion characteristics

Due to the conical coverage pattern of the coaxial driver design the

horizontal and vertical dispersion characteristics of the MAX are largely

identical (slight differences which do occur are attributable to the

cabinet shape). The diagram below shows dispersion angle versus

frequency plotted using lines of equal sound pressure (isobars) at –6 dB

and –12 dB. The nominal 60° dispersion angle is maintained from 4 to

10 kHz.

MAX isobar diagram

Frequency response

The diagrams below show the different response curves for MAX driven

with the D12 amplifier. The response in standard mode with the Linear

setup selected is equivalent to the operation with a linear power

amplifier (SPL at a distance of 1 m (3.3 ft), output voltage 2.83 V).
