FILTER DSD - DIGITAL FILTER RESPONSE
The m920 provides the user with the ability to
change the bandwidth of the digital filter used by
the DAC when monitoring DSD sources. To adjust
DSD digital filter response setting:
• Push and hold the rotary encoder to enter the setup
menu. Then rotate the encoder until you reach the
Filter DSD screen as indicated by the Fd symbol.
• Push and release the encoder to enter the DSD filter
readout.
• Rotate the encoder clockwise to increase the filter
bandwidth and rotate the encoder counter-clockwise
to decrease the filter bandwidth. Available options are
47kHz, 50kHz, 60kHz and 70kHz.
• Once you have set the desired DSD filter response, push
and release the encoder to store the setting and return
to the setup menu, or push and hold the encoder to exit
the setup menu.
LINE OUTPUT MODE
The rotary encoder is used to select and adjust the
volume of the three available sets of outputs (head-
phones, line 1 and line 2). Depending of the output
mode selected here, the two line outputs can either
be selected and controlled independently of each
other, or they can be grouped together and con-
trolled in parallel.* These options depend on how
your m920 is installed – you may want to send the
identical, parallel line outputs to two different input
destinations (power amp, powered monitors, head-
phone distribution etc..). Or you may want indepen-
dent control of two different sets of monitors (mains
and nearfields).
One interesting possibility for having the two line
outputs grouped is a simple 2.1 monitoring setup
- send one set to your monitors and the other to a
subwoofer. Use the level offset feature to trim either
set of outputs accordingly. To select between the two
line output modes:
• Push and hold the rotary encoder to enter the setup
menu. Then rotate the encoder until you reach the two
line output mode options, as indicated by the letters L1
or L2.
• Push and release the encoder to toggle between either
mode, which again we be indicated by the letters L1 or
L2. L1 is what refer to as ‘grouped’ operation, where
both line outputs are selected and adjusted together in
unison. L2 is what we call ‘round robin’, where each line
output is selected and adjusted independently of each
other.
• Once you have selected the mode you require, either
rotate the encoder to advance to the next setup menu
item, or push and hold the encoder to exit the setup
menu.
*NOTE:
When the m920 unbalanced line output 1
is configured for fixed DAC output, the LINE OUTPUT
MODE menu is not available. In this configuration, the
volume control selection toggles between HP and L2.
EXCLUSIVE OUTPUT MODE
This mode allows you to toggle between all three
outputs and mute the output(s) not selected. The
exclusive output mode can be very useful when ref-
erencing between the line outputs (controlling your
speakers) and your headphones. Instead of having to
manually mute or turn down the volume when tog-
gling between outputs, this mode handles it auto-
matically. Once enabled, selecting either line output
turns that output on at its set volume and mutes the
headphone outputs. Selecting the headphone out-
put turns this output on at the set volume and mutes
the line outputs. Note: the exclusive output mode is
saved anytime the m920 is power cycled. To activate
exclusive output mode:
• Push and hold the rotary encoder to enter the setup
menu. Then rotate the encoder until you reach the
exclusive output mode option, as indicated by the
letters EO.
• Push and release the encoder to toggle on, which will
be indicated by the illuminated the decimal points E.O.
(push and release again to toggle off).
• Once you have selected the output mode you require,
either rotate the encoder to advance to the next setup
menu item, or push and hold the encoder to exit the
setup menu.
