3. SETUP MENU continued …
Audio In (applies to MAIN only):
There are three input types to choose from – Digital, Analog-DSP, and Analog-Direct. After highlighting
‘AUDIO IN’ use the buttons to select an input format.
Dig (Digital): Choose from HDMI (possible only if Scaler In is set to HDMI – the same input is used),
any coaxial, any optical, or the AES/EBU connection. Any digital input can be assigned to multiple
Sources. This allows, for example, two unique Setup/Preset settings for the same DVD player – one
for DVDs using the DVD1 Source, and the other for CD music using the CD Source. Note that Dolby
Digital and DTS are transmitted only
through a digital connection.
Anlg-DSP (Analog with Digital Signal Processing): If you want your subwoofer to play from an
analog L/R input, use this setting. Analog input is converted to digital through the AVM 50’s high-end
A/D converters to enable bass management, time alignment, Mode, Bass/Treble, Lip-Sync Delay,
and THX. These are also available for the 6-Ch input, since it can also be set to Anlg-DSP. With the
bass management and time alignment that this provides, the resulting sound quality from
DVD-Audio or multichannel SACD is far better than setting the 6-Ch input to Anlg-Dir. If your player
has bass management and time alignment, defeat it by setting all channels ‘large’ and to the same
distance. This is necessary when using Anlg-DSP, otherwise the processing occurs twice.
Anlg-Dir (Analog-Direct): A/D conversion and Digital Signal Processing are bypassed, and the
preamp plays the traditional role of switching inputs and adjusting levels. There is no subwoofer
output in Analog-Direct, except with 6-Ch input and only
if the source material has a subwoofer
channel recorded in it.
Auto Digital (applies to MAIN only):
When set to ‘Yes’, the AVM 50 switches to Digital when it senses a digital bitstream and to Analog-DSP when
it doesn’t. This feature is useful with digital cable boxes that use the digital output for digital channels and
analog output for analog channels.
HDMI 6-Channel Map: (applies to MAIN only, for DVD-A format only):
There is no current standard regarding which channel on a DVD-Audio disc comes out of which channel on
the preamp when HDMI connection is used between them. If you hear channels coming out of the wrong
speakers, change HDMI 6CH MAP to the setting that makes each channel come from the correct speaker.
Muting (applies to MAIN only):
This eliminates ‘popping’ sounds that may occur with some digital source components during a bitstream
change. If popping is heard when changing chapter on a DVD or channel on a digital satellite receiver or
cable box, use Max setting. However, if the beginning of a track is cut off when playing a CD, use Min setting.
EQ (applies to MAIN only):
For Sources set to Digital or Anlg-DSP, you can preset low and high frequency levels. This is useful for source
components that have frequency irregularities. After highlighting the EQ line, press SELECT and use the
buttons to select LF (low frequency) or HF (high frequency), then use the  buttons to adjust. In the
FM/AM Setup/Presets menu, FM and AM can be adjusted separately. The EQ settings in this menu and the
‘on-the-fly’ BASS / TREBLE adjustments do not
affect each other (see section 4.7).
Speaker Configuration (MAIN only):
Choose between Cinema or Music configuration (section 3.2), or Auto-LFE. When this is selected, the
AVM 50 uses the Cinema configuration if there is LFE in the source material, and changes to the Music
configuration at all other times. Auto-LFE is recommended when using the same player for DVDs and CDs,
and separate Cinema and Music configurations.
