5. Channel pairs that are available for monitoring in this mode include left/right, left surround/right surround and
center/sub. Please note that you cannot monitor individual channels or other pair combinations other than which
are listed above.
6. To select the Left Surround/Right Surround pair, press either the LS or RS switch. The surround channels will now be
sent to the headphone outputs, the corresponding channel switch LEDs will light solid and the previous channel pair
selection will become inactive.
7. To select the Center/Sub channel pair, press either the Center or Sub switch. These channels will now be sent to the
headphone outputs, the corresponding channel switch LEDs will light solid and the previous channel pair selection
will become inactive.
8. To return to the Left/Right channel pair, press either the Left or Right switch. These channels will now be sent to the
headphone outputs, the corresponding channel switch LEDs will light solid and the previous channel pair selection
will become inactive.
9. To exit the 5.1 headphone mode and return to the m906’s normal operating state, press the headphone encoder
switch.
Note:
If you’ve selected a 5.1 source, are currently in the 5.1 headphone mode and inadvertently select a
stereo input source, this mode will automatically become inactive and the m906 will return to it’s normal
operational state. You can, however, select different 5.1 sources while in this mode. CAL mode is not operable
when this mode is active. Also, it should also be noted that this mode does NOT affect any of the 5.1 speaker
output paths nor the fixed level DAC output.
tHe fiXeD LeveL 5.1 Dac oUtPUt
The DACs in the m906 are reference quality circuits which are suitable for all critical monitoring, mixing
and mastering applications. As a bonus feature, we’ve included a fixed level 5.1 DAC output that lets
you access the DACs with a fixed output level. This is an extremely useful feature which allows you to,
for instance, send out a 5.1 channel audio stream to a 6 channel recorder for mastering or archiving
purposes.
This output is fed from whatever you currently have selected as your digital input source. Another
beautiful thing is that you can continue to monitor your control room source while a transfer from this
output is being made. For instance, if you leave the current digital input to listen to an analog input,
the previous digital input will continue to be sent to the fixed level DAC outputs. If you select a different
digital source input, the fixed level DAC will then be fed from that new source.
The lower line of the LCD display will indicate which digital input is active and its sample rate. The s-Lock
status is indicated by the presence of an asterisk (*) to the right of the sample rate.
The 5.1 DAC output level is set to 0dB as the default value on a new m906 system, but this can easily be
changed in CAL mode (discussed later).
