OPERATING - INPUT/OUTPUT SECTION
INPUT
This knob controls the Input level for both the
Analog and Digital Input options. For optimal
performance of the M300 a well-adjusted Input
level is essential.
Analog Input Range
Counter Clockwise : -10dB
Center
: 0dB
Clockwise : +14dB
Digtal Input Range
Counter Clockwise : -18dB
Center
: 0dB
Clockwise : +6dB
1/L - 2/R INPUT LEDs
These LEDs signal with three colors.
Green
: Indicating that you are “well on the
safe side”
Yellow : Reaching optimal performance.
Red : Should only occasionally blink at
absolute peaks in the material you
feeding the M300 with.
The Input knob adjusts the level for both Left
and Right Input channels. If there is a
significant difference between the Input of the
Left and Right channels you should adjust the
Output of the device feeding the M300.
DIG. IN
The M300 has analog as well as digital Input
options. The digital Input is the S/PDIF type
connected via RCA phono cables.
To select/deselect the Digital Input press the
DIG IN button once.
The green LED next to the DIG IN button will
indicate various situations.
LED Off
Digital Input is set to Off. The M300 processes
only the signal present on the Analog Inputs.
This is done on an internal Sample Rate of
44.1kHz.
LED Green
The M300 is locked correctly on the Digital
Input signal. With the digital signal a clock is
supplied. The M300 can lock on either a 44.1
or a 48kHz Sample Rate frequency which are
the most commonly used Sample Rate
frequencies. E.g. a regular CD is 44.1kHz.
Flashing LED
If Digital In is selected but no digital signal is
received or the signal is corrupt the M300
automatically returns to internal clock and
Analog operation. However, the M300 will
continue to look for digital signal on the S/PDIF
Input and this is indicated by the flashing LED.
If you wish to stay in analog mode press DIG
IN once and the LED will stop flashing.
Dual S/R On - LED
When this LED is lit (green) it is indicated that
the Dual Send/Return Routing is selected via
the switch located on the rear panel.
