Passive and 2-Way Active operation

The D6 and D12 amplifiers can drive the MAX12, MAX, M6

und M4 passively, the D12 also allows 2-Way Active operation.

The M2 can only be driven in 2-Way Active operation.

CUT mode

Set to CUT, the cabinet low frequency level is reduced and is

configured for use with d&b active subwoofers.

The operation with D6 and D12 amplifiers

In applications with low continuous levels and low ambient temperatures

HFA mode

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

the system is rolled off. The HFA 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 function

The CPL (Coupling) function compensates for coupling effects

between closely coupled cabinets by reducing the low and mid

frequency level. CPL begins gradually at 1 kHz, with maximum

attenuation below 400 Hz (for M2 250 Hz), providing a balanced

frequency response when monitors are used in pairs. The CPL

function 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).

MAX12 and MAX with other amplifiers

MAX12 and MAX may be driven by any high quality power

amplifier provided the output power does not exceed 500 Watts

into 8 ohms and an additional subsonic filter (25 Hz and 12

dB/octave) is used.

d&b SenseDrive

The D12 incorporates d&b SenseDrive for accurate control of

LF drivers in d&b loudspeakers driven 2-Way Active or in d&b

subwoofers driven actively, resulting in an extremely precise bass

performance, even at high levels. SenseDrive is only available

using a D12 fitted with EP5 connectors and appropriate 5-wire

cabling. For further information please refer to the d&b TI 340

SenseDrive, which is available for download at www.dbaudio.com.
