Placement and connection

Warning! Please read this manual prior to operating the MAP in order to avoid
damage on your valuable equipment.

Also, please make sure all units of your audio/video system are switched off while
connecting or disconnecting any cables to avoid damage of the input and/or output
sections of your units.

Please make sure that your Audionet MAP is installed at a place that is sufficiently
ventilated to allow the heat to leave.

The mains input 23*) is located at the back panel of the MAP. Please use the provided
power cord to connect the MAP to mains. If you want to use a different power cord
make sure that it meets the specifications for your home country.

WARNING:
The electrical specifications at the back must meet the specifications of your home
country.

The mains switch at the back panel has to be switched off before connecting the
MAP to mains. The MAP is a Class I device and must be earthed. Please ensure a
stable earth connection. 'Phase'/'Hot pin' is marked at the back panel (phase) 23.

The MAP is a stand by device. Please use the mains switch 23 at the back panel to
switch on the MAP. After a short time the display reads 'AUDIONET' to show that the
unit is in stand by mode.

Only in case of extended absence (like vacations) or if massive trouble on mains power
is to be expected you should disconnect the unit from mains. Switch off the MAP with
the mains switch at the back panel 23. The display will go out.

WARNING:
Before switching off the mains switch of the MAP, please make sure that all units
connected to the outputs of the MAP are switched off, too.

Additional earth connection

Optionally, there is a special cord available for an additional earth connection to be used
with earth connector 21. Use the screw of earth connector 21 to connect the additional
ground cord to the MAP. Put the plug of the ground cord into a mains socket near your
power cord. The sound will be improved.

We strongly recommend using the additional earth connection!

Audionet Link

In connection with other Audionet devices like AMP I, AMP II, AMP II MAX, AMP
III, AMP IV, AMP VII etc. your MAP is able to switch on/off the complete system.
Please connect a Toslink plastic fibre cable from the Audionet-Link Output 20 at the
back of the MAP to the Audionet-Link inputs of other Audionet devices. For further
instructions please read the user's manual of the other Audionet devices.

Polarisation of mains plug

The correct polarizing of mains is important for reasons of audio clarity and stability.

Therefore the Audionet MAP indicates a wrong polarisation of the mains lead. While
powering up, the MAP checks the mains polarisation. If you read 'Attention:
Mains Phase incorrect!' switch off the MAP and then flip the plug in your wall
outlet.

Connecting the external power supply EPS

Use the provided special cord to connect the optionally available EPS to the EPS-Input
22 at the back panel of the MAP. Connect both (!!) units (MAP and EPS) with mains.
Switch on first the EPS then the MAP. The unit is now in stand by mode.

To disconnect both units from mains please switch off first the MAP, then the EPS.
Before switching off the MAP, make sure it is in stand by mode by pressing the power

key at the front panel or the key on the remote control.

Audio/Video-Connections

Analog Inputs:

Connect 2-channel analog sources to one of the 6 analog inputs 16. If you are using a
recording device (tape deck, MD recorder, VCR etc), connect it to IN 5 15. The signal
on this input is not routed through to the REC OUT output 17 in order to prevent
feedback loops. Analog input IN 4 is setup for Dolby* Pro Logic IIx decoding by default
(the user can change that in the setup menu!). So please connect the analog 2-channel
outputs of your DVD-Player, LaserDisc-Player, VCR or other analog sources, that
playback Dolby Surround coded material, to input IN 4.

If you have the optional phono card installed, plug in the MM- or MC pickup of your
turn table into input IN 6 14 and connect the chassis of the turn table to the ground
screw gnd 13. The phono card offers independent selection of gain, input capacity and

5

input resistance for optimal adjustments to all kinds of available pickup systems. For
further details please refer to the user's manual of the phono card.

Digital Inputs:

Connect your digital sources to digital inputs 1 to 5 10. By factory default digital inputs
2,3 and 5 are setup for multi channel decoding (Dolby Digital and DTS**). Digital inputs
1 and 4 are setup for stereo PCM signals (all default setting can be changed by the user
in the setup menus!). If you have the optional RF-Demodulator card installed, connect
the 'RF AC-3' output of your LaserDisc-Player to digital input 4 9.

Note: Do not forget to set the option 'Set RF-Demod.' to 'available' in the
"Global Setup" menu. You also have to remove the blue jumper on the input PCB.

In order to send DVD-Audio music data across the HighBit interface from the DVD
player Audionet VIP1) to the MAP V2.0, connect digital output 1 of the VIP with digital
input DIGITAL IN 2 of the MAP. Furthermore, you need a second connection running
from digital output 2 of the VIP to digital input DIGITAL IN 3 of the MAP V2.0. Only
in case of both connections are setup and the switch for the interface mode on the back
panel of the VIP is set to h-bit (refer to owner's manual of VIP), it is possible to receive
and decode DVD-Audio data with the MAP.
Note: Data on the Audionet HighBit interface will be recognized and decoded
automatically by the MAP. If the second data connection is missing the MAP will issue
the error message: 'HighBit Cable 2 Out of lock'. Please check the correct
setup and connection of both cables from VIP to MAP.

External 8-Channel Analog Inputs:

Plug in analog multi channel sources (external decoder, DVD-Player with internal
decoder, SACD-Player etc.) into the 8-channel analog input 11 of the MAP.
Note: The External 8-Channel Analog Input has no signal processing at all, only pure
analog volume control!

Analog Outputs:

The output of the front channels L/R 19 (Cinch and XLR) are marked main line out or
main right/main left and are located in the lower left part of the back panel. All other

analog outputs 12 are located in the section ANALOG OUTPUTS in the upper right part
of the back panel. For Center and Subwoofer channel are two outputs available each
carrying the same signal.

Digital Outputs:

Select DigiRec Select in the setup menu, which digital input 2 to 5 10 is routed to the
digital outputs 8. Both formats (optical and coaxial) are always available. The digital
record select works independently, therefore you can use digital out for recording while
listening to a different source.

1

Make sure your VIP supports the HighBit DVD-Audio interface. Software upgrades are available for older models.

6

Video Inputs:

Plug in your cinch/composite video sources into video inputs IN 1 to IN 4 3. S-Video
sources are to be connected to video inputs S-VIDEO 1 to S-VIDEO 4 4. Use the video
inputs in any order as every one of the 8 video inputs can be assigned to every audio
input (see menu 'Channel Setup'). Even multiple assignments are allowed, i.e. one and
the same video input can be assigned to more than one audio input.

Video Outputs:

The video signal assigned to the current audio input is available at the VIDEO OUT
jacks; cinch video at OUT 1 or OUT 2 7 and S-Video at S-VIDEO 1 or S-VIDEO 2 6.
All video signals at the cinch video inputs are converted to S-Video format by the
internal 'Cinch Video to S-Video Converter' and available at the output S-VIDEO 1.
The On Screen Displays (OSD) is only available at video outputs OUT 1 and S-
VIDEO 1 5. In order to prevent unintentional recording of the OSD picture, please
connect your video recording device to video outputs OUT 2 or S-VIDEO 2 as they
never carry the OSD signal.

Further Video In-/Outputs:

A video signal at video output VGA OUT 1 is only available, if you have installed the
optional Progressive Scan Card. Without Progressive Scan Card video inputs Y/R, Cr/G
and Cb/B 2 are decoupled from the corresponding outputs by 0dB-gain video
amplifiers. Connect your DVD-Player and projector to the corresponding in-/outputs.
Note: Please refer to chapter 'Progressive Scan Card' for detailed information about
connection and configuration of the optional Progressive Scan Card.

First Steps

The following provides a short overview of the first steps and their order to setup the
MAP. For any detailed description please refer to the sections 'Usage front panel' and
'Remote control'.

After connecting your MAP V2.0 to the other components of your Hifi or Home Cinema
system (refer to section 'Audio / Video connections'), some setup options have to be
configured. Your MAP needs information about the number of speakers, their distances
from the listening position and sensitivity to work with optimum performance. The
setup procedure is quite easy if you stick to the following order:

1. Number and size of speakers: Use key Bass Manager

(refer to chapters 'Remote control' and 'Preferences / Setup')
Select what kind of speakers you are using. 'Large' refers to speakers that are
capable of reproducing the complete bass domain down to the lowest frequencies.
Use setting 'Small' for bookshelf-type speakers or small sized design speakers that
are not capable to produce a rich bass foundation due to their construction. According

7

to these settings the MAP determines automatically the amount of bass information
that is sent to each speaker. Due to the different calculating operations that are
needed for this bass management, the perceived volume level may vary between
different settings.

2. Distance of speakers to the listening position: Use key Delay Manager

(refer to chapters 'Remote control' and 'Preferences / Setup')
Measure the distance of each speaker to your listening position and enter the number
into the Delay Manager. Your MAP automatically calculates the necessary delay of
each channel so that the music signals arrive at the exact same time at your listening
position. As the delay settings are calculated and setup in real time, the music signal
may be influenced for the short moment of setting the new value.

3. Level setup: Use key TestTone

(refer to chapter 'Remote control', section 'Keys for level setup')
The noise signal will support you to determine the correct level of each speaker, so
all perceived volumes are the same. This setup is necessary as different speakers have
different sensitivities causing different perceived volumes though the input signal has
the same level.

Note: After adjusting the volume levels of all speaker channels we recommend to save
these settings to all input channels as a simple start up for further channel or source
dependent level settings. To save the current level settings to all input channel, press the

following keys on the remote control: Save Setting à à
Now all input channels have the same volume level settings. Of course, you can change

these settings easily for each input channel independently if necessary. After these 3
steps the most important global settings are done.

Following the global setup there are lots of options that are valid for each input channel
separately. These local settings are necessary to meet all the demands of different source
units connected to the MAP's inputs. Please refer to section 'Preferences / Setup',
subsection 'Channel Setup' for further details.
