Power Cord

The unit is shipped with a power cable matching the power outlets

in the country of sale. Only the included power cable has been

approved for use with the M2.

In case of questions please consult an electrician.

DIGM Mode

DIGM Mode will be selected automatically if an optical DIGM signal is

present. (DIGM = Discrete Intelligent Gain Management)

DIGM Mode means:

• The gain of the M2 can be controlled without loss by an external DIGM control

unit, such as B.M.C.'s DAC1.

• For reasons of tonal quality the audio input signal should be received directly

from a fixed level source like a CD player, a DAC or a Phono Amp, without any

further preamplification or signal attenuation.

• The M2 shows the selected gain in the DIGM display – 66 steps from 00 to 66,

each step equals 1dB.

• The M2 switches off in- and outputs, if the optical DIGM signal is lost during

DIGM mode. This may happen by inadvertently switching off the DIGM controll

unit (e.g. DAC1) or an accidentally disrupting the optical fiber cable.

• After disruption and re-establishment of the optical DIGM signal, the M2 can

be again set to DIGM operation by turning the input switch.

• Attention: If there is no optical DIGM signal present after turning the input

switch, the M2 will change to Power Amplifier Mode with maximum gain! As a

precaution, set your CD player (or other sources) on PAUSE.

• The M2's XLR-CI input can only be selected in DIGM Mode. This protects the

XLR-CI input from unintended usage in Power Amplifier Mode.
