(min. and max.)

Two M2 cabinets can be driven by a single A1 mainframe fitted

with an M2 controller module.

CUT switch

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

is explained under the previous section "Operation with D12 -

Controller settings".

LFC level control

The detented LFC control (Low Frequency Coupling) adjusts the

systems low and low/mid response for the different operating

environments of the M2 cabinet.

The

FLOOR

position is the standard setting for a single M2, used

as a floor monitor.

Turning the control to the

PAIR

position, the low and lower/mid

frequency range is further reduced (Corner frequency about

600 Hz). The maximum left position fully compensates the different

coupling behaviour of the low and high frequencies when two

cabinets are used in a paired monitor application.

Turning towards

FREE

increases the systems low end for operation

without floor coupling (e.g. flown).

Dispersion characteristics

The diagrams below show dispersion angle vs frequency plotted

using lines of equal sound pressure (isobars) at –6 dB and –12 dB.

The nominal 45

horizontal dispersion angle is maintained from

800 Hz - 10 kHz.
