8. FREQUENTLY ASKED QUESTIONS
HowdoIndtheIPaddressofmyMDA?
We recommend using Anthem’s ARC Genesis software or us-
ing a utility called Fing. See section 2.2 for additional details.
I’m connecting my DVD player to the MDA using a TOS in-
put, but even if the disc is playing, I do not hear any sound.
The MDA digital input only supports a PCM stream. Access
your DVD player setup menu and change the output format
to PCM.
I have a subwoofer connected to the MDA using an RCA
jack, but even if I’m playing music with lots of low-fre-
quency content, the subwoofer does not work.
Enable the subwoofer (the default setting is o). See section
2.4 for additional information.
I’m sending commands to the MDA using the serial port,
but the MDA does not react.
Make sure to congure your controller to 115200/8-N-1. Make
sure to send the terminator “;” at the end of the command. CR/
LF are not required.
I’mconguringapairofspeakersinstereobridgemode
on zones 1 and 2. I have my left speaker on zone 1 and
my right speaker on zone 2. My source’s left channel is
attached to the Analog 1 left input and its right channel
connected to the Analog 2 right input. I only hear sound
fromtheleftchannel.WhatamIdoingwrong?
Inputs and speakers (even bridged speakers) operate inde-
pendently of one another. Attach your source’s left and right
channels to the Analog 1 inputs and set Zone 1’s Input Source
to Analog 1. When in bridge mode, Zone 1 becomes the “mas-
ter,” so source selection, volume change, tone control, are all
done by accessing the Zone 1 panel. All settings in Zone 2 set
before selecting Stereo Bridge mode are no longer relevant.
My CD player analog output level cannot be controlled
and defaults to a very high level (2 Vrms). When playing
music, the MDA seems to be clipping very often. How can
thisbeavoided?
The MDA allows you to change the trim of any source. Select
the Inputs pane and set the trim level between -6 dB to -9 dB
for the source where your CD player is connected.
How does the MDA work when the On Mode switch is set
toAuto?
When the MDA is in standby, it monitors all analog and digital
connectors to check if the unit needs to turn on:
Analog connectors are monitored for a signal higher than
-60 dBV (1 mVrms).
Digital connectors are monitored by checking if there
is any bit toggling on the coaxial or Toslink inputs. The
MDA doesn’t check for a specic level to achieve <1/2W in
standby, only activity.
When in operation, the active channels are monitored. When
the level drops below -60 dBV (for either analog or digital in-
puts) for the amount of time programmed in the Auto-O de-
lay, the zone turns o. If all zones are o, the unit will go in
standby.
